Cataracts are a common vision condition. More than 24 million Americans over the age of 40 have cataracts, and approximately 50% of Americans will develop the condition by the time they are 75 years old.
A cataract is a clouding of your eye's natural lens. As the condition progresses, your lens becomes increasingly clouded, preventing light from passing through to the retina clearly. This results in a progressive deterioration of vision. Fortunately, clear vision can easily be restored with cataract surgery.
