Cataracts

A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see theexpression on someone’s face. Cataracts are the leading cause of blindness worldwide and they affect more than half of all Americans age 65 and older.

The lens, where cataracts form, focuses light that passes into your eye, producing clear, sharp images. A cataract scatters the light as it passes through the lens, preventing a sharply defined image from forming. As a result, your vision becomes blurred. As you age, tissues within the lens of your eyes break down and clump together which causes your eyes to become less transparent. It is important to make an appointment for an eye exam if you notice any changes in your vision. If you develop sudden vision changes, such as double vision or blurriness, see your doctor right away.
