To get the facts about cataracts, take our true-false quiz. Over 17 million people in the world are blind due to cataracts. When this happens, you may have blurry vision. Sometimes a problem is noticed only when there is either very dim or very bright light. Surgery is needed only if a cataract is causing problems with everyday living or increasing your risk of falls or injury.
Cataracts can occur at all ages, even in babies.
But cataracts are much more common in older adults. By age 75, over 90 percent of people will have some cataract changes. You may be more likely to get cataracts if you have other chronic diseases or if you have injured your eye in some way. All Rights Reserved.
