Prevention

Remember that cataracts cannot be fully prevented. However, taking some precautions may slow the development of cataracts. Wear dark sunglasses to prevent ultraviolet (UV) light rays, especially UVB rays, from hitting the eye. Heavy exposure to UV rays can hasten cataract development, and there is evidence that the effects may be cumulative over many years. This means that no one is too young to protect his or her eyes with sunglasses.

Some eye care practitioners believe that a diet high in antioxidants, such as beta-carotene (vitamin A), selenium and vitamins C and E, may forestall cataract development. Avoiding other risk factors - such as cigarette smoke, air pollution and heavy alcohol consumption - may also help.
