What is the cause and how do I prevent cataracts?
There are many causes of cataracts. The most common cause is aging of the eye. Both eyes are usually affected but often to a different degree. There is no way to consistently prevent cataract development. Several vitamins have been shown to reduce cataract formation but their protective effect is very limited. Avoiding excessive exposure to UV light by using glasses and sunglasses with UV filters may help a little.
