Research suggests that antioxidants and other important nutrients may reduce your risk of cataracts and macular degeneration. Specific antioxidants can have additional benefits as well; for example, vitamin A protects against blindness, and vitamin C may play a role in preventing or alleviating glaucoma.
The following vitamins, minerals and other nutrients have been shown to be essential for good vision and may protect your eyes from sight-robbing conditions and diseases. Incorporating the following foods in your diet will help you get the Recommended Dietary Allowance (RDA) of these important eye nutrients. Established by the Institute of Medicine (National Academy of Sciences), the RDA is the average daily dietary intake level of a nutrient sufficient to meet the requirements of nearly all healthy individuals in a specific life stage and gender group.
While the RDA is a useful reference, some eye care practitioners recommend higher daily intakes of certain nutrients for people at risk for eye problems. (In the following list, mg = milligram; mcg = microgram (1/1000 of a mg) and IU = International Unit.)
Lutein and Zeaxanthin
