Are Coloured Contact Lenses Safe?

Whether it is for Halloween costumes, comic cosplay conventions, theatrical performances, or personal beauty reasons, there is a growing interest in decorative lenses.

People choose to wear contacts for many reasons. Besides their normal corrective function, many people wear contacts for aesthetic and cosmetic reasons. Coloured contacts, in particular, have become very popular in recent years because of their immediate ability to change appearances drastically.

Plano vs. prescription contacts

Typically, coloured contacts, also known as decorative contact lenses, are available in both prescription and plano forms:

Coloured contact lenses with a prescription: Changes your eye colour and corrects your vision whether you are nearsighted, farsighted or astigmatism.
Plano colour contacts: Changes your eye colour with no alternation for vision correction. This type of lens is also known as non-prescription coloured contacts.

Read on to discover the benefits of wearing coloured contacts, as well as some risks you should be aware of before purchasing prescription coloured contacts.

DID YOU KNOW?

Coloured contacts are a fun way to experiment, but it is important to know all the risk factors before trying them out.

Coloured contacts types

Worn for cosmetic purposes, most coloured contact lenses you will find are designed to mimic the natural look of the coloured part of the eye, called the iris.

In general, coloured contacts come in three kinds of tints:

Visibility tint lens: These lenses come with a light blue or light green tint that does not affect your natural eye colour. Their primary purpose is vision correction.
Enhancement tint: These lenses come with a solid but translucent tint that is a little bit darker than a visibility tint. They are worn to enhance your natural eye colour. These are best suited for wearers with light-coloured eyes who want to make their natural eye colour more intense.
Opaque tint: These lenses are non-transparent and can change your eye colour completely. You will need this tint to change your eye appearance if you have dark-coloured eyes.

What are the most naturally coloured contacts?

From the lens collection available at SmartBuyGlasses, Solotica offers a natural look. Combining groundbreaking technology and exceptional colour opacity, their lenses can transform dark eyes into breathtaking blue, green, grey and brown. They are also available as prescription colour contact lenses too.

Hidrocor is a popular collection because it does not have a limbal ring in the outer rim and has CE-certified, ANVISA-certified and FAA-approved natural colour contacts. Natural colours, Aquarellas and our other collections offer soft and stunning looks.

Colour contacts for light eyes

Coloured contacts with enhancement tints are great for people with light-coloured eyes because they define the edges of your iris and deepen your natural eye colour without changing your eye colour completely. If your natural eye colour is blue, and you want to experiment with different shades and still want to keep a natural look, you could try a grey or green contact lens.

Color contacts for dark eyes

If you have dark-coloured eyes and want to change your eye colour, you will have to use opaque tinted lenses to cover up your natural eye colour completely. Try a light honey brown or hazel colour for more natural tones.

Colored contact lenses: frequently asked questions

Do I need a prescription to buy coloured contacts

Coloured contact lenses are medical devices, so before you can buy your first pair of coloured lenses, you must have a valid eye prescription from a licensed optician.
Even if you want plano lenses, you must visit a vision specialist beforehand and have them write you a prescription for wearing coloured contacts.

How to know if I am buying safe contact lenses?

Coloured contacts are absolutely safe – as long as they are properly prescribed, worn, and cared for.
You should never buy or wear coloured contacts unless purchased “over the counter” with a proper prescription and approved by a licensed optician. Decorative contacts sold in flea markets, gas stations, or beauty salons are NOT approved medical devices; you should never buy or wear them.

What are the risks of coloured contacts?

Coloured contact lenses can increase the risk of eye infections, your cornea getting scratched and may also cause eye damage if used incorrectly.
Although it sounds fun and harmless, you should never share your coloured contact lenses with friends or family. Doing so greatly increases your chance of contracting harmful eye infections.

How to wear contact lenses safely: top tips

Wearing contact lenses can improve your vision and give you a different look, but it is important to wear them correctly. Here are some top tips on how to wear contact lenses safely, including essential information about hygiene, storage, and cleaning.

Wash your hands thoroughly before handling lenses.
Don’t wear your lenses longer than the recommended time limit.
Never sleep in your contact lenses.
Remove any makeup or dirt from your eyes before putting on lenses.
Use fresh solutions and clean cases when storing lenses.
Schedule an eye exam at least once a year to ensure everything is healthy.

Are coloured contacts safe for kids?

Halloween contact lenses are a popular choice for people of all ages who want to change their eye colour for an event or just for fun. While these lenses can be a safe and effective way to change your appearance, parents should be careful when considering costume contact lenses for their children.

Contacts require proper care and hygiene to prevent infection and other complications, especially for kids who may not have the same level of responsibility as adults. It’s important to talk to an eye doctor before allowing your child to wear coloured contacts to ensure the lenses are safe, comfortable and properly fitted for their eyes.

How to tell if you have an eye infection from contact lenses

If you wear any type of contact lens regularly, it’s important to keep an eye out for any signs of infection. Symptoms can include redness, swelling, eye pain and discharge. If you’re experiencing any of these symptoms, remove your contacts immediately and see a doctor as soon as you can.

If you wear contact lenses, it may also cause skin irritation from inappropriate wear patterns. This health risk is greater among those wearing poorly-made colours or purchasing from unlicensed vendors. Always seek advice from a medical professional before purchasing any contact lens.

Dominant Eye Test

Dominant Eye Test

Ask our dispensing opticians

Ask now

Which is your dominant eye, left or right? We'll explain how you can tell in this article.

At some point, you may have heard the terms “dominant eye” or “ocular dominance,” but what exactly do they mean, and how can you determine your dominant eye? Since we usually use both eyes at once, having a dominant eye is often an overlooked trait.

Below are some basics on how to find your dominant eye and when eye dominance can make a difference.

How to tell which eye is dominant

A dominant eye doesn’t mean better vision but rather guiding the other better because of preference. Your dominant eye provides slightly more input to the visual cortex of your brain and relays the information more accurately, especially object location.

The visual cortex is the brain region that receives and processes information from the retina.

Eye dominance can vary from person to person. While someone may have a strong degree of dominance in one eye, another may have an eye with a lesser difference in dominance. For most people, eye dominance won’t impact day-to-day living and is more of a curiosity.

DID YOU KNOW?

It is possible, but very uncommon, for a person to have no dominant eye.

The eye dominance test

If you’re curious, there are several techniques to determine your dominant eye. Below are two basic tests, called “sighting tests,” which can be done quickly and easily.

For the first test:

Extend your arms in front of you, with your palms facing away from you, bring your hands together, crossing your thumbs and forefingers to form a small triangular opening.
With both eyes open, choose a small object in the distance (about 15-20 feet away) and center this object as you look through the small opening.
Close one eye at a time. When you close one eye, the object will be stationary. When you close the other eye, the object should disappear from the triangle or jump to one side.

If the object does not move as you look through with one eye, that is your dominant eye. For example, if you look through the opening at the object with your right eye open and left eye closed, and the object is still centered, you are right-eye dominant.

For the second test:

Extend one arm in front of you with your thumb or index finger on that hand in an upright position.
With both eyes open, focus on an object in the distance.
Move your arm so that you superimpose your thumb on that object (it is normal if your thumb partially disappears).
Alternate closing one eye at a time.

The eye that keeps your thumb directly in front of the focused object while the other eye is closed is your dominant eye.

If you still can’t tell, ask your eye doctor at your next eye exam. Some studies have shown that sighting tests, though generally accurate, can be affected by handedness and other non-visual factors. They argue that non-sighting tests are more precise in determining eye dominance.

In these tests, both eyes are kept open and visual stimuli are presented to each eye separately using special optical devices. These tests can only be performed in specialized vision clinics or research facilities.

Eye dominance and handedness

While eye dominance and handedness are not directly related, they may be associated, but it is impossible to predict eye dominance based on handedness alone. Studies suggest that most of the global population is right-handed, but only a third have a dominant right eye.

Research has shown that the odds of a right-handed person being right-eye dominant are high, approximately 2.5 times greater than the odds of that person being left-eye dominant.

Is it possible to not have a dominant eye?

Most people have a dominant eye, but there are rare cases when neither eye is dominant. Some people have mixed or alternating ocular dominance, meaning one eye is dominant for certain tasks while the other is preferred for different functions. There is a spectrum of degree when it comes to eye dominance.

Some people may have a significant difference between their eyes, while others may have a minimal difference.

Dominant eye in sports, shooting, and photography

You may notice your dominant or preferred eye when you use a camera, microscope, or telescope. Understanding which is your dominant eye can improve your performance in certain sports and activities, especially any that require accurate aim.

Minor adjustments to the position of your head or hands can help put your dominant eye in a better spot, allowing you to level up during leisure time or competitions.

Sports

In some sports, taking full advantage of your dominant eye is fundamental and requires positioning your head in a way that allows you to do so. Golf and baseball are two examples in which this is necessary. In golf, certain strokes must be perfectly aligned and require turning your head fully to use and benefit from your dominant eye.

While batting in baseball, your head must be turned enough for your dominant eye to see the pitch’s rotation, position, and speed.

Shooting sports

Some people experience crossed dominance, where their dominant eye and hand are not on the same side. This can cause problems during shooting, but being aware of this can help you make adjustments to improve accuracy.

To shoot and hit moving targets, you should aim with your dominant eye; if you use your non-dominant eye, your target won’t be in the right place. If possible, shooting with the hand that matches your dominant eye is recommended.

Another way to compensate for cross-dominance is to keep both eyes open until right before you take your shot. You can use 100% of your peripheral vision and depth perception with both eyes open.

Photography

Knowing your dominant eye can also aid in taking better photos. When looking through the viewfinder of a camera with your dominant eye, you will get a more accurate preview and alignment of the shot.

If you’re using your non-dominant eye, you may notice that specific details will end up displaced or outside the frame in the final image.

Eye dominance problems

For the vast majority, eye dominance has no bearing on day-to-day living. Generally, the term dominant eye is used to describe the preferred eye in typical visual conditions where both eyes function well as a team. In some cases, dominant eye is used to refer to the normal functioning eye in cases of strabismus or amblyopia.

While not the only cause, a strong dominant eye can sometimes trigger amblyopia or lazy eye. As one eye relays stronger visual signals than the other, it causes the non-dominant eye to become weaker over time.

This can be treated early by patching the dominant eye in hopes of strengthening the non-dominant one. There are also eye exercises that can be done to help improve vision.

Eye dominance

Your dominant eye shouldn’t be an obstacle on a daily basis. It’s beneficial to be aware of this as it can help in certain activities, but as long as your vision is aligned and clear, it shouldn’t matter which eye is dominant.

Conjunctivitis: Self-Care and Causes

Pink eye is the common name for conjunctivitis, an eye infection. Learn about its causes and treatments in this article.

What is pink eye or conjunctivitis?

Itchy eyes, watery discharge or pinkness in the eyes? You might just have conjunctivitis. Commonly known as ‘pink eye’ because of the characteristic colour that appears in the eye, conjunctivitis is the inflammation of the thin, clear covering of the white part of the eye and the inside of the eyelids (conjunctiva).

But don’t fret. It’s a very common infection and easily treated. Read on to find out more about this common infection – and how to avoid catching it in the first place.

Different types of conjunctivitis

There are three types of conjunctivitis; bacterial, viral and allergic. Before we look at the differences between these three, let’s look at the similarities. All three generally develop when you have a weakened immune system, such as a cold (virus) or a sore throat (virus or bacteria). All three are highly contagious.

Finally, although it is helpful to read guides like these to try and identify which type you may have before seeing an eye doctor, it is vital not to self-diagnose and very important that you seek medical help on the first symptoms of pink eye.

DID YOU KNOW?

The chlorine in swimming pools can irritate the eyes and lead to conjunctivitis.

Bacterial conjunctivitis

Bacterial conjunctivitis is caused by bacteria that spreads to your eyes from your respiratory system or your skin. You can also catch it if you rub your eyes when your hands aren’t clean, use eye makeup (mascara) that has been contaminated or share other things that your eyes touch (like a towel) with someone with conjunctivitis.

Contact lenses can also be a vector for carrying conjunctiva mucous. Best practice is to always use new (daily lenses) or clean lenses (reusable) and washed hands to insert them.

Whether you have contracted bacterial conjunctivitis or not, you should throw out any contact lenses after use. In the case of pink eye, take a break from contacts until it clears up completely. Once your eyes are back to full health, it’s safe to use contacts again, but be sure to use a new, fresh pair.

Viral pink eye

Conversely, viral pink eye is caused by viruses like the herpes simplex virus. You can catch it when someone who is infected sneezes or coughs near you and the droplets come into contact with your eyes.

Allergic conjunctivitis

Allergic conjunctivitis happens when your eyes come into contact with pollen and become red itchy, and watery. It is an eye inflammation caused by an allergic reaction and is normally a short-term condition in comparison to the former two.

Conjunctivitis self-care treatments

Conjunctivitis is easy to treat and most cases usually clear up by themselves in 1-2 weeks. You can use medically prescribed antibiotics and eye drops to help clear up a bacterial infection quicker than waiting for it to heal itself.

To help ease discomfort while the infection clears, you can also use lubricating eye drops to prevent your eyes from getting too dry, put cold ice packs against your eyes to soothe swelling and clean the discharge from your eyes with a wet cloth or tissue.

It is important to note that these home care recommendations aren’t a replacement for medical treatment. They are extra tips to help ease discomfort during your healing journey but should not be used instead of a doctor’s recommendation or prescribed medication.

Bacterial conjunctivitis home care

Bacterial conjunctivitis, also known as bacterial pink eye, is a highly contagious condition that affects the membrane lining the outer surface of the eye.

While antibiotic eye drops are the most effective treatment option, there are a few home remedies that can also provide additional relief. For example, normal over-the-counter drops can help with itching and provide temporary relief. Look for “lubricating” drops or “artificial tears”.

Other remedies include the use of warm compresses to reduce inflammation, keeping the affected eye clean and avoiding shared items such as towels or pillows. However, please note that home remedies should not be relied upon solely and that medical attention should be sought if symptoms persist or worsen.

Viral pink eye home care

Viral pink eye, also known as viral conjunctivitis, can be a bothersome and highly contagious condition. While antibiotic treatment is the best course of action for healing the virus, some home remedies can relieve symptoms and aid this healing process along with medication.

For instance, placing a cool compress over your affected eye for 10-15 minutes can help reduce inflammation and ease discomfort.

Another effective remedy is applying aloe vera gel, which is known for its soothing and anti-inflammatory properties. Additionally, of course, keeping your hands clean and avoiding touching your eyes can help prevent the spread of the infection.

Allergic pink eye home care

Allergic pinkeye, also known as allergic conjunctivitis, is a condition caused by an allergic reaction such as hay fever, resulting in the inflammation of the conjunctiva. Symptoms include redness, itching and watery eyes.

In addition to any medical care you receive, there are home remedies that can help control the allergic reaction and alleviate symptoms. Some of these remedies include using a cold compress with a fresh cotton ball and clean water, avoiding allergens and rinsing the eyes with saline solution regularly.

It is always best to visit a doctor for a proper diagnosis and treatment plan, but these remedies can provide some relief in the meantime.

When to seek medical care

If you’re experiencing any symptoms of pink eye, such as redness, itching and green or white discharge from the eye, it’s important to seek medical care. A medical professional can diagnose pink eye and recommend the appropriate treatment, whether it be prescription eye drops, medication or ointments.

It’s especially important to seek medical care if you wear contact lenses, as pink eye can cause significant complications and may even lead to vision loss if left untreated. Don’t hesitate to schedule an appointment with your healthcare provider if you suspect you have pink eye.

How to avoid reinfection

Once your pink eye has cleared up, it’s important to avoid reinfecting yourself. Make sure you throw out any eye makeup or applicators you used when you had conjunctivitis and get rid of disposable contact lenses and solutions if you used them during your infection.

Thoroughly disinfect hard contact lenses, eyeglasses and your lens cases – all three can harbour bacteria. You can read more about how to properly clean these items in our helpful guides available at our Optical Centre.

What Are Mirrored Sunglasses?

Learn all about mirrored sunglasses and their pros and cons in this comprehensive guide.

If you’re someone who loves to express your style while ensuring practicality, mirrored sunglasses could be just what you’re looking for.

In this article, we’ll cover what mirrored sunglasses are, when to wear them, their pros and cons and if mirrored sunglasses come in various lens colours. So first things first, what are mirrored sunglasses?

Mirrored sunglasses are a type of eyewear that features lenses with a reflective coating on the outside. This coating gives the lenses a mirror-like appearance, helping them to reduce glare as more light bounces off them compared to standard tinted lenses.

The popularity of mirrored sunglasses originates from their aesthetic appeal. They exude a feeling of modernity while also offering a sense of mystery and intrigue.

Because of the interplay of light, they can create a fascinating visual impact, boosting the wearer’s style and making a bold statement.

Looks aside, mirrored sunglasses have also become a staple accessory for many people thanks to the practical advantages of their reflective quality.

Benefits of mirrored sunglasses

Mirrored sunglasses, often known as reflective sunglasses, have numerous advantages in addition to their fashionable appeal. Here are some other benefits which mirror sunglasses provide:

Enhanced contrast

Their mirror coating can enhance contrast, vision clarity and reduce glare. This feature can be particularly beneficial in snowy environments, where the vast white surfaces can create blinding glare, affecting safety.

UV protection

While mirrored sunglasses prevent excess light from hitting your eyes, they are also great at protecting against harmful UV rays.

By blocking harmful UV rays, mirrored glasses contribute to maintaining good eye health over time. They can help prevent conditions like photokeratitis (sunburn of the cornea), which can occur after spending prolonged periods in intense sunlight without proper eye protection against UV light.

Style versatility

Mirror shades come in a wide range of frame styles, colours and lens tints. From sporty, athletic-inspired frames to classic sunglasses silhouettes, mirrored lenses can be worn for any occasion.

Increased privacy

The mirrored coating on the lenses acts as a one-way mirror, meaning people can’t see your eyes while you can still see out clearly. Regular sunglasses obscure your eyes to people on the outside too, but mirrored lenses give wearers a greater sense of privacy.

DID YOU KNOW?

Mirrored sunglasses are regularly worn by astronauts to protect their eyes from intense glare and harmful radiation in space.

Downsides of mirrored sunglasses

Although mirrored sunglasses provide several advantages, there are some drawbacks you should be aware of when buying a pair of sunglasses with mirrored lenses.

Maintenance

In comparison to standard sunglasses, mirrored sunglasses demand additional care. Because of their reflective coating, they need more frequent cleaning as they’re more prone to being marked by smudges and fingerprints. Some mirror sunglasses may have a scratch-resistant coating, although it’s still important to take extra care of them.

You can do so by always cleaning them with a microfiber cloth to remove smudges, as using tissues, towels or clothing can further harm your lenses. When not wearing them, keep them in a protective case to avoid scratches.

Cost

Mirrored sunglasses can also be more expensive than regular tinted sunglasses due to the additional manufacturing process required to apply the reflective coating.

Colour distortion

Mirrored glasses can also sometimes distort the perception of colours. The reflective coating, while effectively reducing glare and enhancing visual comfort in bright conditions, can alter the appearance of objects and surroundings by reflecting different hues onto the lenses. This distortion of colours may affect activities that require accurate colour perception.

Fine detail and contrast

When wearing mirrored sunglasses, less light reaches your eyes, which can mean that you don’t see fine details as clearly. Depending on the colour of the lenses, this can also affect contrast.

Mirrored vs polarised sunglasses

Mirrored and polarised lenses cater to diverse needs and preferences, each offering unique benefits. Mirrored lenses boast a reflective coating that deflects light away from the eyes, reducing glare and enhancing visual clarity, making them perfect for sunny outdoor activities.

On the other hand, polarised sunglasses are designed to reduce glare from horizontal surfaces like water or pavement, improving visual clarity and reducing eye strain.

So, choosing between mirrored and polarised sunglasses often depends on the specific activities and environments you anticipate encountering.

When to wear mirrored sunglasses

As mirror sunglasses reflect glare, they’re an excellent choice for outdoor activities. Here are a few situations in which they come in handy:

Beach activities

When gearing up for beach activities, a pair of sunglasses with reflective lenses emerge as the perfect accessory.

They’re excellent at handling glare from the sand and water, enhancing your beach adventures or any water sports.

Outdoor sports

Whether you’re cycling through rugged terrain, shredding down snowy slopes or trekking along sun-drenched trails, mirrored sunglasses will be highly beneficial. Their ability to reflect light rather than absorb it ensures reduced eye strain, making them a must-have for your outdoor pursuits.

Daytime driving

When you’re behind the wheel, glinting sunlight can be a nuisance as it bounces off the road, car hoods, LCD screens located in your car or other vehicles.

Mirror sunglasses can significantly reduce glare from these reflective surfaces and protect your eyes, providing clearer vision and enhancing safety on the road.

Do mirrored lenses come in different colours?

When it comes to selecting the perfect pair of sunglasses, mirrored lenses stand out as a popular choice. However, a common question arises: Do mirrored lenses come in different colours? The answer is yes. Here is a brief overview of the options available.

Silver lenses

Silver mirrored lenses typically provide true colour perception and natural contrast. They’re suitable for a wide range of outdoor activities, making them a classic and versatile choice for everyday wear.

Green lenses

Green mirrored lenses offer excellent contrast and depth perception while minimising colour distortion. These would specifically be beneficial if you’re playing golf or going fishing as they provide better contrast between the surfaces and objects beneath.

Red lenses

Red mirrored lenses are extremely popular as they offer a brighter view and reduce eye fatigue.They are particularly favoured among snow sports enthusiasts and runners, who often opt for them during early morning runs to benefit from their brightening effect which enhances visibility and reduces eye fatigue.

Blue lenses

Blue mirrored lenses are popular for their stylish appearance and ability to reduce glare. They also provide a soothing effect on the eyes, making them a fashionable and functional choice. Because of this aspect, these are particularly beneficial if you enjoy outdoor sports such as sailing or cycling.

Gold lenses

Gold reflective lenses provide a warm, soothing tint that enhances contrast and depth perception. They offer excellent glare reduction and are particularly effective in bright sunlight.

As a result, they are perfect for activities like driving or hiking, where varying light conditions demand optimal vision. Additionally, gold lenses also make a fashionable statement as they add a touch of glamour to eyewear choices.

Why should you go for mirrored sunglasses?

A pair of mirrored sunglasses is an ideal option for individuals seeking something more from their eyewear. Their trendy and modern design not only catches the eye but also helps to keep your eyes safe from UV rays, and shade them from harsh glare and uncomfortable levels of brightness on sunny – or even overcast – days.

Whether you enjoy being outdoors or simply love the fashion appeal of mirrored sunglasses, getting a pair of these sunglasses is a decision that you’re unlikely to regret.

With tinted eyeglasses and sunglasses, you can get different benefits to better your vision and maintain your eye health.

SUMMARY

The term tinted glasses refers to eyewear with different coloured lenses, such as blue, green, brown, or yellow.

They help reduce glare and improve contrast and visibility in various conditions.

Today’s eyewear comes in a variety of different colours and with many different features and add-ons. For those with a more specific use in mind for their eyewear, it is worth checking the options for tinted lenses.

Besides the fact that there are multiple types of eyeglass tinting to opt for, they all have unique benefits that they bring with various suggested uses.

What are tinted glasses?

Tinted glasses are simply a type of sunglasses or eyeglasses lens. They are created by coating a UV-blocking lens with different tints: blue, green, brown, yellow etc. Tinted lenses are both a fashion statement and a great way to protect your eyes against harmful UV rays and enhance the contrast.

There are two types of tinted eyewear, solid and gradient tint. Solid-tinted lenses are the most popular and have one colour applied to the entire lens.

Gradient lenses (not to be confused with photochromic lenses) usually transition from a plain colour at the top towards a clear lens at the bottom of the frame. Unlike photochromic lenses, the lens coating stays gradual and does not change according to the sunlight.

What are tinted glasses for?

Deciding what colour tint is best for sunglasses can change depending on your lifestyle and what you will do while wearing your sunglasses. Lighter tints can be great to add a little style to your look, while darker tints can provide more visual comfort in different light and weather conditions.

Green-tinted sunglasses

Green lenses are considered the most protective type, as this tint blocks blue light and UV rays, reducing eye strain and glare in bright environments. These tinted lenses are great for:

Rainy or sunny weather conditions
Golf and tennis
Outdoor activities

Blue/Purple-tinted sunglasses

Blue and purple-tinted glasses improve colour perception and object contours. They offer great protection from reflective surfaces like water and snow. The features of these tinted eyeglasses are ideal for:

Eliminating sun glare
Misty, foggy, and snowy weather conditions
Hockey
Cricket

Red/Pink-tinted sunglasses

Red or pink lenses soothe the eyes as they block blue light and minimise eye strain and glare from screens. They can also improve depth perception and enhance details. When are they suitable to wear?

Driving / Racing
Skiing and other winter sports

Dark amber, copper, or brown-tinted sunglasses

Dark amber, copper or brown lenses are usually indicated for people with myopia, as they can help enhance contrast and clarity. These lens colours also provide UV protection and can help judge distance in hazy and foggy conditions. The activities that pair well with these tints include:

Driving
Fishing
High altitude sports

Gray and black-tinted sunglasses

Gray and black lenses are a fantastic option for everyday use and work on bright and overcast days. This option of coloured lenses provides accurate colour perception while offering the most significant light reduction, reducing eyestrain. You should grab a pair if you are into the following:

Water sports
Deep-sea fishing
Very sunny conditions
Baseball

Yellow-tinted glasses

Yellow tints filter out blue light and help the eyes pick out soft colours, which is beneficial in low-light conditions such as indoor sports and overcast days. Ideal activities for this colour of tinted sunglasses are:

Hiking in shaded areas
Mountain biking
Indoor use
Driving

Are tinted lenses worth it?

The importance of eyeglass tinting becomes evident after using the correct lenses for your activities. Tinted lenses provide adjustments that help you go through your day with ease. For example, they equip wearers with the best alteration to stay safe when enjoying their favourite pastimes and sports.

They can help with photophobia, providing visual comfort to light-sensitive individuals
They can be used indoors and outdoors for better visibility. Tinted lenses can be great both outside as protection from the sun’s UV light as well as inside to safeguard your eyes from the blue light emitted by digital devices
Style and fashion options
More affordable than polarised sunglasses
Reduce visual stress

What are the disadvantages of tinted lenses?

Tinted eyeglasses and sunglasses also have a few downsides worth noting:

They can sometimes cause colour distortion
No advanced glare protection: Tinted lenses do not reduce glare/horizontal reflection

What is the difference between tinted and polarised lenses?

The main difference between polarised and tinted lenses is that polarisation reduces glare to the minimum.

Polarised lenses protect your eyes from UVA or UVB radiation; they also cut out horizontal light reflected from surfaces that create a distracting glare, making it difficult to see. Polarised sunglasses also enhance colour perception.

Moreover, polarisation is a filter integrated directly into the lens material, while the tints applied to glasses and sunglasses are an additional add-on.

Overall, polarised lenses remain a great option for anyone who spends a considerable amount of time outdoors, particularly on the water, where they can drastically improve comfort and safety.

DID YOU KNOW

Tinting is an add-on added to your lenses, while polarization is a filter integrated into the lens material. Tinted sunglasses are great for reducing brightness and UV rays, but they don’t necessarily eliminate harsh glare like polarised sunglasses can.

Should I try tinted lenses?

Glasses and sunglasses are not just fashion accessories; depending on what tint you choose, you can get different benefits to better your vision and maintain your eye health.

At SmartBuyGlasses, you can combine your prescription or plano lenses with grey, brown and green tints (even in different gradients) to match them with your needs and activities.

If you’re looking for guidance on adding a pair of tinted glasses to your wardrobe and are unsure where to start, talk to your eye doctor or our online team of certified opticians. They can help narrow your options to match your budget, needs and lifestyle.

Thin Glasses Frames – Are They Right for You?

Finding it challenging to decide which glasses frames to wear next? This guide will help.

Thought thin glasses frames were strictly reserved for older generations? Think again. Among fashion-forward men and women, thin-frame glasses are now linked with a sophisticated, elegant aesthetic.

Advantages of thin glasses frames

There are a few benefits to choosing thin glasses frames. Here are just some of them.

Comfort

Glasses with thin frames have a range of advantages, the most appealing being comfort. When you have a light frame material, your glasses weigh less, meaning a more comfortable experience.

No nose bridge imprint

Say goodbye to that unsightly nose bridge imprint! You know the one. Removing your eyewear shouldn’t have you feeling self-conscious about the mark left by nose pads.

Fortunately, with thin glasses frames you can be reassured that you are much less likely to experience this issue.

The minimal force at the points of contact between your face and glasses can make a big difference over a whole day of wearing your specs.

If you have a high prescription, you may still experience added weight on your nose, so this is something to consider when looking at thin frame glasses.

Snug fit

Continuously nudging your eyeglasses back up the bridge of your nose? Nudge no more. Thinner frames lend themselves to a closer fit on your face.

Coupled with the lightweight, slim design of thin frame eyeglasses, you no longer need to deal with them sliding down your nose.

Even those with thick lenses can enjoy this benefit. Thanks to technological advancements, it is easier to find lenses that fit your strong prescription needs and still offer sleek, thin lenses.

However, if, for example, you have -7.00 prescription in a 1.74 lens index, your glasses overall would still be thicker and heavier.

Do thin frames suit you?

Thin glasses frames offer a distinct look, and the benefit of lightweight comfort. Consider the below points when deciding whether they should be your next pair.

Give it personality

The right pair of eyeglasses needs to tick the function and style boxes for every wearer. Especially if you wear yours regularly, they should complement your look.

If you’re after a bold aesthetic, don’t shy away from these frames on account of their narrowness. Play with colour and materials to make your look stylish, while still enjoying the lightweight design.

Face shape

Determining which face shape you have is useful to help you narrow down the types of frames you should consider. Oval, square, round and heart… all of these face shapes have an ideal thin glasses frame pairing.

You can use our convenient face shape guide to see which category you fall into, as well as some tips for each face type.

What about your lens prescription?

Your lens prescription will have a role to play in the frames you wear. For each prescription, there is a recommended lens index.

The lens index indicates how light refracts through a lens, and in conjunction with your prescription, indicates the thickness; the higher the index, the thinner and lighter the lens can be made.

With a low index, your choice of eyeglass frames is narrowed down because your lenses are thicker, requiring the right frames to comfortably fit into.

With a high index, you may find you have more options to choose from, or could even go with a rimless option.

Finding the lightest weight frames

So, we already know that thin frame glasses are naturally more lightweight than their thicker framed counterparts.

You can also explore different materials, like metallic or acetate, to lighten the weight of your glasses even more.

Stainless steel

Stainless steel thin metal glasses frames have the advantage of being durable, strong, non-corrosive, and tend to be more affordable than some other popular metal materials like aluminium.

Flexon

Flexon is a popular choice for those with an active lifestyle. It’s a titanium alloy, and because it’s able to return to its original shape after being bent or twisted, its flexibility is suited to those who spend their time out and about.

Constantly bending and snapping your glasses? Flexon could be a good material for your frames.

Titanium

Strong and resistant to corrosion, titanium is another popular option for those who want their thin metal glasses frames to last.

If you have sensitive skin, titanium could be a smart choice if you want a metallic frame; its hypoallergenic, so it won’t irritate your skin.

DID YOU KNOW?

Titanium has evolved into one of the most desirable materials for all types of items.

Acetate

If a metallic frame isn’t for you, you can experiment with colors by choosing acetate. Ideal for men and women who want to keep their look simple yet fashionable, these lightweight frames offer a sophisticated choice.

Experiment with different colours and finishes for a style that suits you.

Balance practicality with style

Choosing eyeglass frames can be challenging when you have such a variety of styles to shop from.

Now that you know about the different materials and colours to choose from, you can browse with confidence knowing that a pair of thin frame glasses allows you to enjoy the benefits of practicality while staying stylish.

Contact Lens Brands

Choosing your brand | Contact lens types | Brands | Best Contact Lenses | Does contact lens brand matter? | Changing contact lens

Read our helpful guide to discover more about the different contact lens brands on the market.

Millions of people opt for contact lenses every day over prescription glasses. Contact lenses are thin, curved lenses placed on the eye’s surface (aka “Cornea”) to correct your vision. They’re typically transparent and unnoticeable. However, they also come in various colours that can change your look while providing the same benefits.

How do I choose the right brand?

If you are a first-time contact lens wearer, you may feel overwhelmed by all the contact lens brands and available options. Luckily, you will not have to worry about the options available as contact lenses are fitted by your eye doctor. This includes a thorough eye examination to identify your visual impairment and overall health. So you can decide what the most suitable style for you is.

A physician may also advise you about the replacement schedule and brand. Following this, you can take a look at our quick and easy guide to help you understand the breakdown of major contact lens brands out there.

What are the two types of contact lenses?

Contact lenses are either hard or soft. Hard contact lenses are more durable but are more difficult to adjust to. On the other hand, soft lenses are typically more comfortable to wear and take less time to get used to.

Please read our guide below before you buy contact lenses online to be sure to purchase the pair that matches your optician’s prescription.

What brands of contacts are there?

Johnson & Johnson

Johnson & Johnson is a leader in contact lens technology and was the first company to invent the fantastic silicone hydrogel material that is now being implemented in almost all contact lenses on the market.

Johnson & Johnson is most well-known for introducing Acuvue contacts, the world’s #1 prescription contact lens brand. In fact, Acuvue was the first company to present and sell daily disposable contact lenses. They offer a wide range of options for contact lens wearers with different wear time preferences and even toric lenses for astigmatism. If you are looking to buy contact lens brands for astigmatism, consider the following:

Acuvue

DID YOU KNOW?

There are many types of contact lens brands available for different needs, but your optometrist will always prescribe you the best for your eye issue.

What is the best contact lens brand?

If you already wear contact lenses, you probably have a favorite brand of lenses that you stick to. If you’re considering the switch from glasses to contacts, you’ll undoubtedly want to learn more about each of the main brands.

Acuvue is one of the most popular and highly recommended contact lens brands on the market. They manufacture a wide range of extremely comfortable lenses. If you’re searching for a well-known and well-respected lens brand, Acuvue is likely to be recommended to you by your doctor.

Other popular and highly recommended contact lens brands include Dailies, Air Optix, Biofinity, and Soflens. With so many brands to choose from, it’s always important to research and speak to an optician to find the right pair for you. Remember, you don’t need to worry about brands as your Eye Care Professional is going to fit you with the correct lenses for your eyes.

Does contact lens brand matter?

When it comes to contact lenses, different brands may have different levels of comfort and convenience for specific needs, so be sure to consult with your eye doctor before purchasing contact lenses.

It is important to remember that contact lenses are medical devices and must be prescribed by a qualified eye care professional. By working with your eye doctor, you can ensure you get the contact lenses that best match your vision correction needs and lifestyle. Your eye doctor can also provide guidance on contact lens safety, care, and wear to help keep your eyes healthy.

Ultimately, contact lens brand does matter. With the right contact lenses, you will be able to enjoy clearer vision and improved comfort. Put your mind at ease by researching the various brands available so you can be sure to understand everything that your doctor recommends in your contact lens prescription.

Can you change contact lens brand?

It’s common for a friend or family member to recommend their lens brand since they know they’re comfortable. However, keep in mind that what works for one person may not work for another.

Before switching contact lenses, you’ll need a new fitting before, even if the contacts are the same brand. This is because different contact lenses have different curves and dimeters which alter the fit. Remember to always ask your optician before changing contact lens brand.

There are so many contact lens choices available at SmartBuyGlasses. If you have any questions about which contact lens brand is best for you, don’t hesitate to ask one of our certified online opticians.

What Are Asian Fit Glasses?

Ask our dispensing opticians

Ask now

Depending on your facial features, Asian fit glasses may be the best for you. They have special features that give you the most comfortable fit and stops the frames from sliding down your nose.

SUMMARY

Asian fit glasses are specially designed with a lower bridge to better fit unique facial features, such as a lower nose bridge, higher cheekbones and a rounder face shape.

This design provides a comfortable fit that prevents the frames from sliding down the nose, pressing against the cheeks, or feeling tight around the temples.

If you are having problems with your glasses fitting your face comfortably, then this article all about Asian fit has the answers you are looking for.

Do you find that your glasses sit tightly, always slide down your nose or sit too close to your eyelashes? Then maybe your face is telling you to upgrade to a pair that fits your facial features the way they are supposed to.

What does Asian fit mean in glasses?

We all look different and we all have different facial features. Just think about how, nowadays, anyone can unlock their phone by simply placing it in front of their face.

When choosing a pair of glasses, remember that what fits your face won’t necessarily fit another – just like your face is the only one to unlock your phone. It could be your eye shape, bone structure and so on.

Do you feel that your glasses do not correctly fit your face because they are too tight at the temples or always slip down your nose? For people with lower nose bridges and high cheekbones in particular this is a common issue. Due to the diversity among facial features, standard glasses aren’t always the right fit.

We have a solution!

Asian fit glasses are designed specifically to help avoid these issues. Also known as low bridge fit glasses or Omni fit, Asian fit eyewear can be more comfortable for people of Asian descent but is also not limited to them.

Asian fit sunglasses and glasses cater to specific facial features. If your answer is yes to any of these questions below, then you may want to consider getting yourself a pair of low bridge fit glasses:

Do you have flatter facial features?
A rounder and wider face?
A low nose bridge and/or higher cheekbones?

If you’ve said yes to 1 or more of the above questions, then sit back and let’s have a look at what your face is saying.

Humans have adapted to their environment and climate for centuries, and based on these factors, our bodies have mutated to fit our surroundings, even our facial features.

Our noses, for example, have adapted to diverse climates, and if you live in a more humid climate, you’ll tend to have a wider nose to allow for more air to flow.

Facial features

In the Asian community, many tend to have a lower nasal bridge, the part that is between your eyes and close to your forehead. Therefore the bridge of your nose is lower than your pupils, making it harder for the glasses to sit correctly on your face and align with your vision.

If you have higher cheekbones, your glasses will tend to touch your cheeks, so when you talk or smile, you’ll see your glasses move as well. If your eyewear is always leaning on your cheeks, it can be uncomfortable.

With a wider and rounder face, standard glasses can be a little tighter around the temples or quite often sit too high on your face.

Can non-Asians wear Asian fit glasses?

Whether you are from an Asian community or not, having these particular facial features may entail that Asian fit glasses are designed specifically for you. If you have a smaller face shape you may also opt for an Asian fit.

What is the difference between Asian fit and standard fit?

Now that we’ve established who and for which particular facial features Asian fit glasses are, we can see exactly how they work.

3 main aspects make Asian fit glasses a little different from Standard fit glasses:

Asian-fit glasses are designed with larger nose pads that ensure the glasses sit correctly on your face and away from your eyelashes. Standard fit glasses, instead, have a shorter bridge meaning that they may not fit well if you have a low nose bridge.
The lenses are shorter, wider, and slightly tilted. This helps prevent the glasses from constantly touching your cheek and helps to create a gap between your face and the lenses. With your glasses sitting further away from your face, you’ll also reduce the risk of your eyewear fogging up, a pain every glasses wearer endures.
The frame is wider and slightly curved for rounder and prominent heart face shapes, to prevent the glasses from being too tight at the temples or sitting too high on your face.

Round and heart-shaped faces tend to have a wider forehead which means that some regular or smaller size glasses would be too tight and squeeze your face. If you are not entirely sure what your face shape is, you can easily find out with our shape face guide.

Are Asian fit glasses smaller?

Just like any clothing item that we wear, even glasses have a particular size, whether they are standard fit or Asian fit. They are smaller in some aspects, but it will depend on the measurement.

Sunglasses, and glasses in general, have 3 different measurements:

The first measurement indicates your lens width
The second number is the width of the bridge
The third is the temple width

Extra nose pad features

For Onmi fit glasses, you want to ensure that the bridge or nose pads have the right size to sit correctly on your nose. The size can also differ depending on the frame material used.

Generally, bridge measurements on standard-fit glasses vary from 14-24 mm, but if it is too wide on your nose bridge, the glasses may slip down.

DID YOU KNOW?

There are many differences between Asian and Standard fit glasses. Finding out if you need Asian fit can make your experience much more comfortable.

Frame type

Plastic frames with a solid nose bridge for Asian fit glasses can measure around 8mm and this helps provide support and less slipping. A great example is Ray-Ban Asian fit glasses, which sit just right on your face and avoid any touching between your cheeks and glasses.

Many metal frames, for example, have adjustable nose pads that you can adjust to fit the glasses properly on each side of your nose. Certain metal frames can have a nose bridge of up to 11mm. Measurements for low bridge glasses can tend to be lower than the standard fit but do vary. But don’t let all these numbers stop you from getting a pair of trendy and cool Asian fit glasses.

Great-looking, better-fitting glasses

If you have a low nose bridge, wide and flat facial features or high cheekbones, then most probably Asian fit glasses are just the right eyewear for you.

Look trendy with a pair of Asian fit eyeglasses or low bridge sunglasses that fit; avoid the pain of your eyewear moving inconveniently or them fogging up your vision because they are too close to your face.

What Are Blue Light Glasses?

What Are Blue Light Glasses?

Ask our dispensing opticians

Ask now

Discover how blue light affects our eyes and dive into how blue light glasses work.

SUMMARY

The purpose of blue light glasses is to block the harmful blue light emitted by digital screens from reaching the eyes, which can disrupt your circadian rhythm.

By limiting the amount of light that reaches your eyes, blue light glasses can offer several benefits, such as reducing eye strain, improving sleep quality and more.

Disclaimer: Blue light glasses are intended to benefit individuals who spend long hours in front of digital screens or are exposed to artificial blue light sources. However, it’s important to note that the scientific evidence supporting these benefits is still evolving, and individual experiences may vary.

Have you ever finished your gaming session or work day with tired and irritated eyes?

In today’s digital era, our lives are intricately intertwined with screens, from smartphones and laptops to tablets and e-readers.

As we navigate this digital landscape, we often overlook the potential implications of prolonged screen exposure on our eye health and overall well-being.

That’s where blue light-blocking glasses step in, offering a potential solution to the problems caused by blue light emitted from digital devices.

What is blue light?

Blue light refers to a specific range of electromagnetic radiation within the visible light spectrum.

Blue light rays are at the high end of the visible light spectrum and have the shortest yet most powerful wavelength (380-460nm).

Blue light waves are the closest to invisible waves and ultraviolet rays, which are known to be the most dangerous of all light waves.

Because of its higher energy, blue light is more likely to scatter in the atmosphere, which is why the sky appears blue during the day.

So is blue light harmful?

It’s important to note that not all blue light is harmful. Blue light is present naturally in sunlight (largest source of blue light) and plays a crucial role in regulating our circadian rhythms.

The primary concern arises from excessive exposure to artificial sources of blue light, particularly from digital devices, LED lighting and energy-efficient light bulbs.

Therefore, it is best to be safe and protect your eyes from blue light with a pair of blue light-blocking glasses.

The purpose of blue light glasses

The primary purpose of blue light-blocking glasses is to reduce digital eye strain and discomfort caused by digital devices (that emit blue light).

When we spend long hours in front of computers, smartphones, tablets or other electronic screens, we expose our eyes to higher levels of blue light than what they would naturally encounter from daylight.

Symptoms of digital eye strain (also known as computer vision syndrome) may include eye fatigue, dry eye syndrome, blurry vision, headaches, discomfort in the neck and shoulders and difficulty falling asleep.

Blue light-blocking glasses work by selectively blocking or filtering out a portion of the blue light spectrum, aiming to reduce these potential negative effects.

By wearing blue light-filtering glasses, some individuals report experiencing less eye strain and improved comfort while using a digital device for extended periods.

DID YOU KNOW?

The most common symptoms of the negative effects of blue light are: eye fatigue, dry eyes, blurry vision, headaches and discomfort in the neck and shoulders.

What are the benefits of blue light glasses?

Blue light-blocking glasses are designed to mitigate the potential negative effects of excessive blue light exposure from digital screens.

While the scientific evidence supporting their benefits is still evolving, many users who wear plano and prescription glasses with a blue light filter report experiencing some positive results.

Reduced eye strain

Prolonged screen time can lead to digital eye strain, which may cause symptoms like dry eyes, blurred vision, headaches and eye discomfort.

Blue light-blocking glasses can help reduce eye strain by filtering out a portion of the blue light that contributes to these symptoms.

Improved sleep quality

Blue light exposure, especially during the evening or nighttime, can suppress the production of melatonin, a hormone that regulates sleep.

Wearing glasses that block blue light in the evening or using devices with blue light filters can help maintain the body’s natural circadian rhythms and improve sleep patterns.

Enhanced comfort

People often report feeling more comfortable when using a computer screen and other devices while wearing blue light glasses, as the glasses can help reduce the harsh glare and intensity of screens.

Potential retinal protection

Some studies suggest that excessive exposure to blue light, particularly high-energy blue-violet light, might contribute to retinal damage over time.

Blue light glasses with specific coatings may offer protection against potential long-term damage, although more research is needed to establish this and other benefits conclusively (Dawnie et al. 2019).

Minimised risk of macular degeneration

Some researchers believe that long-term exposure to blue light could be associated with an increased risk of age-related macular degeneration (AMD) (Zhao et al. 2018).

Wearing blue light glasses might help reduce this risk by limiting the amount of harmful blue light reaching the eyes, safeguarding your macular health.

When should you use blue light glasses?

Since blue-blocking glasses filter out possible harmful wavelengths of light, they are best worn in situations where you risk being exposed to too much blue light.

This includes almost all electronic devices with screens – so, whether you’re watching television, checking your phone or working at a computer, blue light-blocking glasses can prevent sleep issues and minimise your risk of eye strain, headaches and difficulty sleeping.

We suggest wearing blue light-filtering glasses:

On extremely bright, sunny days
In front of a computer monitor (i.e. when playing video games)
When using your phone (especially at night)
When a migraine feels imminent

When having long sessions of extended screen time, it is strongly recommended to safeguard your visual performance by taking frequent breaks, wearing computer glasses and making sure the device is at least at arm’s length.

Are blue light glasses really necessary?

If you worry about the impact of blue light on your eyes and sleep patterns, you may consider trying a quality pair of blue light-blocking glasses, especially if you have a lifestyle that involves extensive screen use.

As always, it’s a good idea to consult with an eye care professional to determine the best approach for your specific needs.

What is Blepharitis?

Ask our dispensing opticians

Ask now

Blepharitis is a condition that irritates the eyelids. Learn all about it and how to treat it.

Disclaimer: We at SmartBuyGlasses are not medical doctors. This article contains general advice. If your eyelids are inflamed, consult your doctor or an eye care professional for treatment.

Blepharitis is a medical term that indicates an inflammation of the eyelids. This occurs due to infection at the base of eyelashes or when the tiny oil glands at the base of the eyelashes become clogged.

It’s characterised by an inflammation of the eyelids that causes sore red eyelids or crusty eyelashes.

This condition may also cause burning, itching or a gritty sensation. Although blepharitis is not sight-threatening, it can lead to discomfort and chronic conditions if not treated and managed.

Eyelid inflammation is very common. In a survey of American ophthalmologists and optometrists, eye doctors reported that 37% and 47% of their respective patients had experienced blepharitis symptoms at some point in their lives. (Lemp & Nichols 2009)

Luckily, eye doctors are able to prescribe effective blepharitis treatments that can limit eyelid inflammation and help resolve the issue.

What are the causes of blepharitis?

Blepharitis is caused by a type of bacteria that lives on the skin, a skin condition such as seborrheic dermatitis and the glands inside the eyelids not producing enough oil.

However, there are several other possible causes of blepharitis, including:

Seborrheic dermatitis, a chronic form of eczema
Rosacea, a skin condition characterised by facial inflammation
Dry eyes (something you may experience and linked to blepharitis)
Allergies, including allergic reactions to eye medications, contact lens solutions or eye makeup
Parasites (Demodex eyelash mites)
Eyelash extensions

DID YOU KNOW?

Blepharitis is most likely a multifactorial condition (Eberhardt & Rammohan 2023), meaning it can have multiple causes, such as bacterial infections, inflammatory skin conditions and parasitic infestations.

What are the symptoms of blepharitis?

The most common symptoms of blepharitis include:

Burning or stinging eyes
Crusty debris at the base of eyelashes
Irritated, watery eyes
Itchy eyelids
Grittiness or a foreign body sensation

Depending on the severity of blepharitis, you may have some or all of these symptoms and blepharitis symptoms may be intermittent or constant. In some cases, blepharitis also causes loss of eyelashes (madarosis).

Blepharitis is also a common cause of contact lens discomfort, forcing many people to give up on wearing contacts. Blepharitis can cause disruption to the tear film, which can affect contact lens wear comfort.

Are there different types of blepharitis?

Blepharitis can be categorised into two types, anterior blepharitis and posterior blepharitis, based on its location on the eyelids.

Anterior blepharitis

Anterior blepharitis is commonly caused by a bacterial infection (staphylococcal blepharitis) or dandruff of the scalp and eyebrows (seborrheic blepharitis).

These bacteria are commonly found on the face and eyelids, but if they become excessive or the lid area reacts poorly to their presence, an infection may occur. Less commonly, allergies or a mite infestation of the eyelashes can cause anterior blepharitis.

Posterior blepharitis

Posterior blepharitis can occur when the glands of the eyelids irregularly produce oil (meibomian blepharitis). This creates a favorable environment for bacterial growth.

Posterior blepharitis can also develop as a result of other skin conditions, such as rosacea and scalp dandruff.

Am I at risk for blepharitis?

In some cases, a person might be more at risk of contracting blepharitis. For example, these are some risk factors:

Wearing contact lenses
Not removing makeup thoroughly
Having oily skin
Having dandruff
Suffering from allergies
Having rosacea

What not to do with blepharitis?

To effectively manage blepharitis, there are a few things you should avoid during the course of the treatment.

It is advisable not to wear contact lenses while experiencing symptoms, as they can worsen the condition and hinder the healing process.

Additionally, refrain from using eye makeup, especially eyeliner and mascara, as they can introduce irritants.

It is also recommended to replace any eye makeup that has been used to avoid reintroducing the bacteria.

On the other hand, there are also some to-dos you can follow. Firstly, make it a habit to clean your eyelids twice a day at the beginning of your treatment with the prescribed eye lid wash from your healthcare professional.

As your symptoms improve, you can gradually reduce it to once a day. Eyelid hygiene cleaning is important even if your symptoms clear up, as it helps maintain good eye hygiene.

Blepharitis treatment

If you’re experiencing symptoms that you think may indicate blepharitis, it is recommended to see an eye doctor for an eye exam. He or she will assess the best way to treat your condition with some of the following methods:

Eye drops. Steroid eye drops can control redness, swelling and irritation. Also, artificial tears may be an option.
Medicines to fight infection. If your blepharitis is caused by bacterial infection, your eye doctor may prescribe topical antibiotic eye drops, ointments or pills.
Treating the root causes. Treating an underlying health issue such as rosacea or dandruff, if it is the cause of your blepharitis, can be beneficial in alleviating the symptoms.

Follow your doctor’s advice, and your blepharitis should heal up in one or two weeks, depending on the severity. For any doubts or questions, you can always consult our certified online opticians.
