In a normal eye, light passes through the lens and gets focused on the retina. To help produce a sharp image, the lens must remain clear. Although we know that cataract develops because of the change in the chemical composition of the lens, we do not know exactly what causes these chemical changes to happen. The symptoms of cataract are as follows - Cloudy or blurry vision. Problems with light.
Colours seem faded.
Poor night vision. Frequent changes in your eyeglasses or contact lenses. These symptoms can also be a sign of other eye problems. If you have any of these symptoms, check with your eye care professional. A regular eye examination is all that is needed to find a cataract.
