If you’re concerned about vision loss and improving your ocular health, you can improve your chances of keeping your eyes in good condition by eating healthfully and following a supplement regimen. Vision can deteriorate over time, and this may be a result of genetics, environmental toxins, a poor diet, or even side effects of prescription drugs. Some people experience eye problems as a result of sinus infections and seasonal allergies. Taking supplements to support the health of your eyes can be a valuable way to help preserve your vision and ease eye-related conditions.
Among the common causes of vision loss and poor eye health are:

• Obesity.


• Gender (the risk is higher in women than in men).


• Family history.


• Smoking.


• High blood pressure.


• Diets lacking in key nutrients.

Research: The Eyes Have It

In 2001, researchers at the National Eye Institute published a study highlighting the effectiveness of various vitamins and nutrients in supporting eye health. The Age-Related Eye Disease Study found that high doses of vitamin C, vitamin E, beta-carotene, and zinc may reduce the risk of age-related macular degeneration (AMD), a condition that often leads to blindness. AMD is of special concern to the aging population, and causes small whitish-yellow fatty deposits in the center of the retina, ongoing vision loss, and sometimes dryness of the eyes.

A 1994 study highlighted the role of carotenoids in reducing the risk of vision loss and blindness. Carotenoids are nutrients found in green, leafy vegetables, and can easily be incorporated into a high-antioxidant diet. Supplements that contain high levels of antioxidants such as vitamin C and vitamin E may lower the risk of eye diseases and strengthen natural tissue.

Zinc is an important mineral for eye health, since the eyes rely on their high concentration of zinc to send and receive nerve transmissions. An antioxidant, zinc can help keep the immune system and skin healthy as well. Effective macular protection often begins with a zinc supplement or multivitamin with high levels of zinc.

Bioflavonoids, such as those found in various fruits, can also play a role in improved eye health. They may prevent damage caused by free radicals, and can easily be included in a diet with five or more servings of fruits and vegetables each day. Common extracts in supplements include:

• Grape seed.


• Green tea.


• Ginkgo leaf.


• Bilberry fruit.


• Lemon.

Lutein has often been associated with eye health and reducing the risk of blindness, but scientists and doctors have yet to confirm a strong link between lutein and eye disease. However, more studies are being conducted to investigate the direct effects of lutein in the diet, and whether it can be linked to macular degeneration.

To support the health of your eyes, valuable additions to your daily regimen may include zinc, vitamin C, and vitamin E. However, these supplements are just that—supplements to a balanced diet and healthy lifestyle.
