Short Sightedness (Myopia) – This is when images are focused in front of the retina instead of on it, which makes distant objects appear blurry.
Long Sightedness (Hyperopia) – Hyperopia is the opposite of myopia; the eye focuses images slightly behind the retina. Distance vision can be blurred, and as an object moves towards you, the more your vision will blur.
Astigmatism – The cornea of the eye is usually spherical. If it resembles a rugby ball shape instead, you have astigmatism.
Presbyopia – This condition is associated with ageing. It causes blurred vision at reading distance and causes an insufficient focusing power for other near distance tasks.
Glaucoma – Glaucoma develops when increased fluid pressure builds up inside the eye. The increased pressure can damage the optic nerve and over time cause loss of vision.
Cataracts – A cataract is the clouding of a normally clear lens. Images can become dull and blurred as a cataract grows and over time sight becomes worse.
Macular Degeneration (MD) – MD occurs when the central part of the retina, the macula, degenerates. There are two types of MD – the dry form and the wet form.
