Our eyes operate similar to a camera, each using a lens to see clearly. The eye lens is made of water and protein. Sometimes the protein clumps together to form a cataract. A cataract can occur in one or both eyes, but it does not spread from eye to eye.
Cataracts can be caused by the aging of the protein in your eyes, smoking, diabetes, surgery or an eye injury.
- Cloudy or blurry vision

- Headlights, lamps or sunlight may appear too bright

You may also require frequent changes to your eyeglass or contact lens prescription. The symptoms may be improved with new eyeglasses or using anti-glare sunglasses. But if not, surgery is the only effective treatment.
The surgery for cataracts involves removing the cloudy lens and replacing it with an artificial lens. Cataract removal is one of the most common operations performed in the United States.
