As you think about ways to improve or preserve your eye health, it's important to realize that vitamins and nutrients are not a cure for eye disease, nor will they give you back vision you may have already lost.  However, good nutrition at all ages is vital for your entire body, and plays an important role in maintaining healthy eyes.  

Foods rich in vitamins C and E, zinc, lutein, zeaxanthin, and omega-3 fatty acids DHA and EPA are good for eye health as well as general health, according to the Age-Related Eye Diseases Study (AREDS).  These foods are linked to lower risk for age-related macular degeneration (ARMD), cataracts, and dry eyes.  Eye-healthy food choices include citrus fruits, vegetable oils, nuts, whole grains, dark green leafy vegetables, and cold water fish.

People who have diabetes or ARMD or are at risk for these diseases can also benefit by following a low-glycemic index diet.  The GI value is based on how fast a food's carbohydrates raise the body's blood sugar levels; low GI foods have less impact on blood sugar fluctuations.

People with macular degeneration may be able to slow the progression of the disease by taking a special nutritional supplement called the AREDS formula, developed as a result of the AREDS research.  This is promising news for people who are at risk for or already have ARMD.  Be sure to discuss any supplements with your primary care physician as well as your eye physician.  You may learn more about these supplements on this site's Nutriceuticals page.

Making healthier food choices is a good thing no matter how early or late in life we begin.  Encouraging good eating and exercise habits with kids sets patterns they're likely to stick to their entire lives.  As an adult, you  should speak to your eye physician about any concerns regarding your eye health and for specific recommendations involving nutritional supplements.
