What Are Cataracts?
Inside our eyes, we have a natural lens. The lens bends (refracts) light rays that come into the eye to help us see. The lens should be clear, like the top lens in the illustration.
Vision Problems with Cataracts
If you have a cataract, your lens has become cloudy, like the bottom lens in the illustration. It is like looking through a foggy or dusty car windshield. Things look blurry, hazy or less colorful with a cataract.
What Are the Symptoms of Cataracts?
Here are some vision changes you may notice if you have a cataract:
- Having blurry vision
- Seeing double (when you see two images instead of one)
