What Causes Cataracts?
Most cataracts are caused by aging. But certain risk factors can increase your risk of cataracts.
For example, long-term exposure of the eyes to ultraviolet (UV) radiation from sunlight and other sources has been associated with cataract formation. Smoking, certain medications, and health problems such as diabetes and hypertension also increase your risk of cataracts.
Some cataracts called traumatic cataracts can occur at any age following an injury to the eye. And sometimes, cataracts are present at birth; these are called congenital cataracts.
Cataracts are common and affect more than 20.5 million Americans over age 40.1
