What Causes Cataracts to Occur?
A cataract is most often related to aging of the eye. A family history of cataracts can be a factor. In addition, a history of diabetes, eye injury, smoking, or the long-term use of certain medications (most notably steroids) can also play a role in the development of cataracts. Frequent and extensive exposure to ultraviolet light has also been shown to hasten the development of cataracts. No specific evidence exists that links diet and the development of cataracts.
