Do you know the signs of cataracts?
When you have a cataract, the normally clear lens of the eye becomes cloudy. This makes seeing difficult. Cataracts can form very slowly. The first signs can be:
- Clouded vision
- Glaring or sensitivity to bright light
- Poor night vision
- Faded color vision
- Double or multiple vision in one eye
- Frequent changes in prescriptions for eyeglasses or contact lenses
Usually cataracts are related to aging. More than 17% of Americans ages 40 and older have a cataract in one or both eyes. More than half of all Americans ages 80 and older have cataracts.2 Other causes can be:
- Using cigarettes or alcohol
- Eye injuries
- Excessive sun (UV) exposure
- Certain medications
- Diabetes
