Cataracts

What is it?

A cataract is clouding of the lens in the eye.

Causes:

There are many factors that increase the risk of having cataracts. Exposure to ultraviolet light causes damage to the lens of the eye and, with time, may lead to cataracts. Trauma or surgery of the eye increases the risk of cataracts. Diabetes and genetic disorders, such as galactosemia, may put you at a higher risk for having cataracts. Some medicines, such as prednisone or cortisone, can increase the risk of cataracts. Smoking may even increase the risk of having cataracts.

Signs and Symptoms:

Cataracts usually develop slowly over time, making the changes in vision gradual and less obvious. You may not see as clearly and have trouble seeing in dim lighting as the lens becomes cloudy. If the lens becomes totally cloudy, you will lose sight in that eye.

Wellness Recommendations:

Wear sunglasses outside on sunny days. If you smoke, quit.

Medical Care:

When you cannot see well enough to safely do your activities, surgery may be done to remove the lens of the eye.

Dietary Measures:

  • Spinach, tomatoes, cruciferous vegetables (broccoli and cauliflower), citrus fruits, and melons may decrease your cataract risk.
  • Eating foods high in beta-carotene and vitamin C may prevent cataracts.
  • Eating large amounts of salt, fat, and butter may increase your cataract risk.

Herbs and Supplements:

Before taking any herbs or supplements, ask your caregiver if it is OK. Talk to your caregiver about how much you should take. If you are using this medicine without instructions from your caregiver, follow the directions on the label. Do not take more medicine or take it more often than the directions tell you to. The herbs and supplements listed may or may not help treat your condition.
