Zinc has some antioxidant characteristics and is found in the retina. Zinc play a major role in bringing Vitamin A from the liver to the retina, helps Vitamin A create a protective pigment called melanin. Zinc also helps support the health of tiny capillaries in the eye, which are essential in nourishing the retina and related connective tissue. Zinc and copper, in balance (15:1 ratio between zinc to copper as zinc uses copper in the body), help support a proper acid balance in the body, which in turn helps may help avoid development of new floaters.
Zinc is not stored very well in the body. Those who eat meat or seafood likely get enough zinc. Although there are large amounts of zinc in beans, grains, and nuts, apparently due to plant phylates zinc is not well absorbed. Therefore, zinc supplementation may be important for vegans and vegetarians. This is especially important for diabetics since zinc helps to inhibit the develop of a serious condition called sugar cataracts. Check with your medical provider if you think you should be supplementing with zinc.
