Cataract: Vision Problem

A clouded lens is referred to as a cataract. The lens is positioned behind the eye's coloured area. Clear, sharp images are produced on the retina as a result of the lens's ability to concentrate light entering your eye. A cataract prevents a sharp image from reaching your retina by scattering and blocking light as it travels through the lens. The vision is consequently blurred. Usually, but not always, cataracts form in both eyes at the same time. There may be a variation in vision between the two eyes as a result of one eye's cataract being further along than the other.
