What is a Cataract?


A cataract is the gradual clouding of the part of your eye known as the crystalline lens. Cataract formations occur at different rates and can affect one or both of your eyes at the same time. A cataract is not a foreign body in the eye nor a growth of any sort nor a film over the eye.

How do I know if I have a cataract?

Most cataracts are found during routing eye examinations by the ophthalmologist. Persons over 40 should have their eyes checked approximately every two years. Examinations performed before the lens is completely clouded give valuable information about the back of the eye. If a cataract does develop, the ophthalmologist will have a better idea how much vision can be improved by surgery.

Why do cataracts form?

This clouding is usually due to the aging process but can also be caused by eye trauma, heredity, diabetes, and even some medications. Whatever the cause, cataracts typically result in: Blurring of eyesight, especially in bright light; visual distortion when reading (e.g. inability to distinguish between letters); brighter and clearer vision in one eye.
