A cataract is a clouding of the natural lens, the part of the eye responsible for focusing light and producing clear, sharp images.
The lens is contained in a sealed bag or capsule. As old cells die they become trapped within the capsule. Over time, the cells accumulate causing the lens to cloud, making images look blurred or fuzzy.
- For most people, cataracts are a natural result of aging.
- People with diabetes tend to get cataracts more commonly and at a younger age.
- Surgery for cataract is highly successful resulting in a dramatic improvement in quality of life.
