Eyes Home > Information on Cataracts
Cataracts occur when the lens of the eye becomes cloudy. As a result, the flow of light is distorted and the picture formed on the retina becomes dim or blurry. This can result in symptoms such as:
- Blurry vision
- Poor night vision
- Difficulty reading
- Frequent prescription changes in eyeglasses.
Although there are many different types, age-related cataracts are the most common. In fact, by the age of 80, more than half of all Americans either have a cataract or have had cataract surgery.
