Driving glasses Driving glasses are glasses/lenses may incorporate an anti-reflective coating that eliminates the glare from street lights or headlights, helping drivers by reducing the risk of being blinded by light. They’re often worn at night, but driving sunglasses also exist.

Diopter
Diopter Diopter (D) – A unit of measurement used to measure the power of a lens, indicating its ability to bend light. Diopters is the measurement used to record nearsightedness, farsightedness and astigmatism. For instance, a lens with a -2.00 diopter is used to correct myopia, meaning it helps focus distant objects more clearly.
Blepharitis
Blepharitis Blepharitis – A chronic condition characterised by inflammation of the eyelids, usually affecting the area where the eyelashes grow. It can cause symptoms like itching, redness and crusty flakes. Although uncomfortable, blepharitis isn’t contagious and is usually manageable with good eyelid hygiene and, in some cases, medicated treatments.
Bifocal Lenses
Bifocal lenses Bifocal lenses – Eyeglass lenses that contain two distinct optical powers in one lens. The upper part of the lens typically corrects distance vision, while the lower part is designed for up-close vision, such as reading. These lenses are commonly prescribed for people with presbyopia who also have a refractive error like myopia …
Astigmatism
Astigmatism Astigmatism – A common vision condition that consists in a refractive error due to the cornea (the clear front surface of the eye), lens, or both being too curved. This causes light to focus unevenly on the retina, resulting in blurred or distorted vision at all distances. Corrective lenses or minimally-invasive surgery can typically …
Corneal Ulcer
Corneal ulcer Corneal ulcer – A serious eye condition that affects the cornea, usually due to infection from bacteria, viruses, fungi, or parasites. Symptoms include severe pain, redness, discharge and blurred vision. Corneal ulcers require prompt medical treatment to prevent permanent vision loss.
Corneal Abrasion
Corneal abrasion Corneal abrasion – A scratch or injury to the cornea, the eye’s clear, protective layer. Symptoms include pain, redness, watery eyes or increased tearing and sensitivity to light. While some corneal abrasions heal on their own, more often they need additional eyedrops to speed up the cell regeneration. They can also sometimes lead …
Anti-reflective Lenses
Anti-reflective lenses Anti-reflective lenses – Lenses treated with a multi-layer coating that reduces reflections from the lens surface and reflects artificial light. This enhances clarity, minimises glare from screens, headlights and bright lights, and allows others to see your eyes clearly. These lenses are ideal for driving at night, working on computers, or any situation …
Blue Light Lenses
Blue light lenses Blue light lenses – Lenses that are specifically designed to filter out a portion of high-energy visible (HEV) blue light emitted from digital screens and artificial lighting. Prolonged exposure to blue light can contribute to digital eye strain and may disrupt sleep patterns. These lenses are particularly useful for those who spend …
Conjunctivitis
Conjunctivitis Conjunctivitis involves the inflammation or infection of the conjunctiva, the thin, clear tissue covering the white part of the eye and the inside of the eyelids. Symptoms include redness, swelling, itching and discharge. Conjunctivitis can be caused by bacteria, viruses, allergens (in which case it’s also known as pink eye), or irritants, Bacteria conjunctivitis …
