Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is important in the xanthophyll cycle. The name is derived from Zea mays in which zeaxanthin provides the primary yellow pigment, plus the Greek word for yellow. Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers.
Therefore, zeaxanthin has only three stereoisomeric forms. The (3R,3'S) stereoisomer is called meso-zeaxanthin. Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is the pigment that gives paprika, saffron, and many other plants their characteristic color. Foods considered good sources of lutein and zeaxanthin include eggs, spinach, goji berry, kale, turnip greens, collard greens, romaine lettuce, broccoli, zucchini, kiwifruit, corn, garden peas, swiss chard and Brussels sprouts.
In this third segment we will take a look at the important role diet can play in preventing vision problems and some of the best food items for eye health.

DHA is also used as a treatment for macular degeneration and for sight preservation.
Carotenoids are the yellow, orange, and red pigments synthesized by plants and found in many colored vegetables and fruits. Some of the most common carotenoids found in plant-rich diets include alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein, zeaxanthin, and lycopene.
