What Causes a Cataract? Is There Any Way to Get Rid of It Without Eye Surgery?

A cataract is a clouding of the whole or part of the lens inside the eye, resulting in blurred or distorted vision. It may be caused by normal aging (age-related), exposure to the sun's ultraviolet radiation over many years, injury (traumatic) or disease (secondary). Most cataracts occur and develop after age 55 slowly but some babies are born with cataracts (congenital).

In general, there is no way to prevent age-related cataracts. If you have eyeglasses or contact lenses, make sure they're the most accurate prescription possible. Limit your night driving. When you go outside during the day, wear sunglasses to reduce glare.
