There is no proven way to prevent cataracts. However, certain lifestyle habits may help slow cataract development. These include:

• Not smoking.
• Wearing a hat or sunglasses when you are in the sun and avoiding sunlamps and tanning booths.
• Eating a diet rich in vitamins C and E. Eat at least 3 servings of fresh fruits or green, leafy vegetables, and take a multivitamin every day. There is no solid proof that these foods prevent cataracts, but researchers are studying this.
• Limiting your alcohol intake.
• Avoiding the use of steroid medicines when possible (some people need them).
• Keeping diabetes under control.
