Vitamin A and Carotenoids
Published February 1st, 2007
Carotenoids are a class of highly unsaturated yellow to red pigments occurring in plants and animals. They are the natural extracts from which Vitamin A is derived. Three carotonoids most often mentioned in the context of eyes are beta carotene, lutein, and zeaxanthin. Lutein and zeaxanthin appear to be particularly important to eye health. They have been found to be highly concentrated in the macula of healthy retinas and appear to neutralize free radicals generated when ultraviolet and blue light strikes the retina.
