Cataracts




I have never had a cataract before but my friend did one time. We were in junior high and we were hanging out at school one time and I noticed something a little bit different with her eye. I really didn't notice much of her eye, it was just a little bit of red. She said she couldn't see really that good, and that her eyes were getting blurry. The next day she went to the doctor and they told her that she had a cataract eye.

A cataract is a painless, cloudy area in the lens of the eye that blocks the passage of light to the retina. The retina is the nerve layer at the back of the eye. The nerve cells in the retina detect light entering the eye and send nerve signals to the brain about what the eye sees. Because cataracts block this light, they can cause vision problems.

Your doctor can find out if you have cataracts by doing a physical exam and by asking questions about your symptoms and past health. You may need other tests to make sure you have a cataract or to rule out other conditions that may be causing vision problems.
