What science has to say
Plenty of claims are made about the positive effects of supplements on vision and eye health, but very few research studies support these claims. One exception is the Age-Related Eye Disease Studies (AREDS). These are large studies conducted by the National Eye Institute. The studies focused on two conditions that affect millions of Americans, age-related macular degeneration (AMD) and cataracts.
What supplements may help my eye health?
The following supplements, including the antioxidants, have been shown to be beneficial for eye vision.
Lutein and zeaxanthin
Lutein and Zeaxanthin are carotenoids. Carotenoids are pigments found in plants and in your retina. Supplementing these pigments helps increase their density in your retina. They also absorb high-energy blue and ultraviolet light that can damage your eyes.
Also found naturally in your eyes, zinc is a powerful antioxidant that protects against cell damage. Zinc is the primary mineral in the AREDS2 formulation. When taking zinc, copper absorption is lessened. It’s recommended that zinc be combined with copper supplements.
Vitamin B1 (thiamine)
Vitamin B1 is essential for the health of your eyes. There’s evidence that vitamin B1, taken with other vitamins, may reduce your risk of getting cataracts, but more research is needed.
Known as one of the “anti-stress” B vitamins, vitamin B1 reduces inflammation.
Initial research also indicates that it may be an effective for treating uveitis, an inflammatory eye condition that can lead to blindness.
Omega-3 fatty acids
The diet of most Americans doesn’t contain enough omega-3 fatty acids, the main source of which is fish. Photoreceptors cells in your retina contain a large quantity of omega-3 fatty acid. It’s believed that docosahexaenoic acid (DHA), a type of omega-3 fatty acid, helps in the development of retinal cells. It’s also thought to have a role in reducing inflammation and helping cells of the retina and the cornea heal and regenerate after damage due to light exposure and aging.
A number of studies indicate that people who consume more of two omega-3 fatty acids, DHA, and eicosapentaenoic acid (EPA), were less likely to have AMD. Low levels of omega-3 fatty acids are associated with dry eye syndrome and retinopathy, a disease that causes progressive damage to the retina. Research has also shown that infants whose formula contains DHA develop better vision than infants not given DHA.
Several large studies show that vitamin C reduces the risk of getting some types of cataracts. Two of these studies also found that a combination of vitamins C and E supplements reduced risk for cataracts and slowed the progression of cataracts.
Eyestonia is a special formulation that has been specifically chosen to help maintain good vision health. Contains bilberry, lutein, zeaxanthin, vitamin A, vitamin D3, vitamin E, zinc and copper. The combination of antioxidants and vitamins in Eyestonia helps to increase macular pigment optical density (MPOD) and visual acuity of the eye and maintain night vision. The carefully selected ingredients in Eyestonia help to maintain and support your vision health.
