Overview

A cataract is a clouding of the lens of the eye. The lens focuses light on the retina at the back of the eye. Cataracts block some of the light and make it harder for you to see clearly. Cataracts often develop when you get older.

Most cataracts grow slowly. At first, you may just need stronger glasses to help you see better. Later, if the cataracts grow and begin to seriously impair your vision, you can have surgery to remove them.

How can you care for yourself at home?

• Move room lights and use window shades to avoid glare.
• Use more lighting or higher-watt bulbs.
• Use a magnifying glass for reading. Look for large-print books and other reading material to make reading more enjoyable.
• Have your eyes checked regularly, and update your glasses when needed.
• Wear sunglasses to block out harmful sunlight. Buy sunglasses that screen out ultraviolet A and B (UVA and UVB) rays.
• Do not smoke. Smoking can make cataracts worse. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
