Hydrophobic glasses Hydrophobic glasses – Lenses treated with a hydrophobic coating that repels water, preventing droplets from sticking to the surface. This makes the lenses easier to clean and keeps them clear in rainy or humid conditions, improving visibility and comfort for the wearer.

Ocular hypertension
Ocular hypertension Ocular hypertension – A condition characterised by higher-than-normal pressure inside the eye, which can increase the risk of developing glaucoma. Unlike glaucoma, ocular hypertension does not cause damage to the optic nerve or vision loss by itself but requires monitoring and management to prevent potential complications.
Nose pads
Nose pads Nose pads – Small, soft pads attached to the glasses frame where they rest on the sides of the nose. Nose pads provide comfort and help keep the glasses in place, preventing them from slipping down the nose. They are usually adjustable and can be made from materials like silicone or rubber for …
Nose bridge
Nose bridge Nose bridge – The part of the glasses frame that sits on your nose, connecting the two lenses. A well-fitting nose bridge distributes the weight of the glasses evenly, ensuring comfort and stability. Different styles of nose bridges are available to accommodate various nose shapes and sizes.
Night vision glasses
Night vision glasses Night vision glasses – Glasses designed to improve visibility in low-light conditions, such as during nighttime driving. These glasses often feature anti-reflective coatings and yellow-tinted lenses to reduce glare from headlights and streetlights, enhancing contrast and making it easier to see in the dark.
Myopia
Myopia Myopia – Also known as nearsightedness, a vision condition where close objects are seen clearly, but distant objects appear blurred. Myopia occurs when light focuses in front of the retina instead of directly on it, usually because the eyeball is too long. Glasses or contact lenses with negative diopter values (minus lenses) are used …
Macular degeneration
Macular degeneration Macular degeneration – Age-related Macular degeneration is a condition that affects the macula, the central part of the retina responsible for sharp, detailed vision. Macular degeneration leads to the gradual loss of central vision, making it difficult to read, recognise faces, or see fine details. While there’s no cure, treatments can slow its …
Hyperopia
Hyperopia Hyperopia – Also known as farsightedness, a common vision condition where distant objects are seen more clearly than those that are close. Hyperopia occurs when light entering the eye focuses behind the retina rather than directly on it. Corrective lenses with positive diopter values (plus lenses) are typically prescribed to help focus light correctly …
Glaucoma
Glaucoma Glaucoma – A eye diseases characterised by increased pressure within the eye (intraocular pressure) that can damage the optic nerve. This damage can lead to progressive vision loss. Regular eye exams are crucial for early detection and management, as glaucoma can cause irreversible blindness if left untreated.
Glasses sphere
Glasses sphere Glasses sphere – The part of your glasses prescription that indicates the strength of lens power required to correct nearsightedness (myopia) or farsightedness (hyperopia). The sphere (SPH) value is measured in diopters, with a minus sign (-) denoting myopia and a plus sign (+) indicating hyperopia.
