Lutein (pronounced loo-teen) and zeaxanthin (pronounced Zee-uh-zan-thin) are two substances that you are likely to hear the most about if you have AMD (age related macular degeneration). These are two chemicals from a group of substances called carotenoids and act like internal sunglasses protecting your eyes. Lutein is found in spinach, kale, collard and mustard greens, and egg yolks. Plants make other types of xanthophylls; however, lutein is the only one that accumulates in the eye. Zeaxanthin is much like lutein and together they help produce a richer and more vibrant pigment in the retina. This helps protect the macula from further degeneration.
