How Vitamins and Supplements Can Promote Eye Health

For most people, vitamin deficiency isn’t enough to cause a severe vision problem, and a supplement can’t necessarily stop an eye problem from developing. Still, deficiency of certain vitamins can affect eye health, and for patients with a family history of cataracts and other eye problems, loading up on the vitamins might not hurt.

Lutein and Zeaxanthin

Lutein and zeaxanthin are antioxidants located in the eye, and they may help reduce the risk of chronic eye diseases, according to the American Optometric Association. They filter out harmful light rays to protect and maintain healthy cells. They also help prevent oxidation of the lens, which can lead to cataracts. Plus, researchers with the Age-Related Eye Disease Study 2 (part of the National Eye Institute) determined that high concentrations of these vitamins may help slow the progression of age-related macular degeneration (AMD). However, there was no evidence that these supplements could completely prevent macular degeneration. Since the body does not naturally produce lutein or zeaxanthin, they can be taken through supplements or leafy greens like spinach or kale, egg yolks, and other fruits and vegetables.

Other Vitamins for Eye Health

Vitamin A is probably the most famous vitamin for eye health; it’s the reason why so many parents encourage children to eat their carrots. Vitamin A can contribute to eye health and help people with AMD and cataracts, and rhodopsin—also found in carrots—promotes better vision in low-light situations. Vitamin C provides crucial antioxidants, can help slow the progression of cataracts, and can provide vitamins for AMD patients, while Vitamin E adds an additional layer of protection against these eye conditions. Omega-3 fatty acids also promote eye health; while there’s no evidence that they can prevent or slow most conditions, researchers have found evidence that they may provide relief from symptoms of dry eye.

Eating healthy fruits and vegetables packed with lutein, zeaxanthin, and other vitamins won’t give you superpowers, but they certainly promote better vision and may help slow the progression of certain eye conditions.
