What Do You Know About Cataracts?
More than half of Americans 80 years and older have cataracts, the National Eye Institute (NEI) says.
1. Most cataracts related to aging are caused by proteins clumping in the lens of the eye.

The correct answer is
The clumps of protein cloud the eye's lens. The lens is a clear part of the eye that helps to focus light on the retina, the light-sensitive tissue at the back of the eye. The lens must be clear for the retina to get a sharp image. Cataracts cut the amount of light that can reach the retina, the NEI says. This process is a gradual one, progressing so slowly people don't notice much change in their vision. The cataract becomes a problem when the cloudy areas grow large enough to blur or dull vision. Cataracts can also develop when the lens slowly changes color, from clear to yellowish-brown. This type of cataract puts a brown tint on the world, making it more difficult to see blues and purples.
