Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is important in the xanthophyll cycle. Synthesized in plants and some micro-organisms, it is the pigment that gives paprika (made from bell peppers), corn, saffron, wolfberries, and many other plants and microbes their characteristic color.
The name (pronounced zee-uh-zan'-thin) is derived from Zea mays (common yellow maize corn, in which zeaxanthin provides the primary yellow pigment), plus xanthos, the Greek word for "yellow" (see xanthophyll).
Xanthophylls such as zeaxanthin are found in highest quantity in the leaves of most green plants, where they act to modulate light energy and perhaps serve as a non-photochemical quenching agent to deal with triplet chlorophyll (an excited form of chlorophyll) which is overproduced at high light levels during photosynthesis.
Animals derive zeaxanthin from a plant diet. Zeaxanthin is one of the two primary xanthophyll carotenoids contained within the retina of the eye. Within the central macula, zeaxanthin is the dominant component, whereas in the peripheral retina, lutein predominates.
Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field. Early on there are often no symptoms. Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. While it does not result in complete blindness, loss of central vision can make it hard to recognize faces, drive, read, or perform other activities of daily life. Visual hallucinations may also occur but these are not serious and do not represent a mental illness.
Macular degeneration typically occur in older people. Genetic factors and smoking also play a role. It is due to damage to the macula of the retina. Diagnosis is by a complete eye exam. The severity is divided into early, intermediate, and late types. The late type is additionally divided into "dry" and "wet" forms with the dry form making up 90% of cases.
Prevention includes not smoking, exercising, and eating well. Vitamin supplements do not appear to be useful for prevention. There is no cure or treatment that returns vision already lost. In the wet form, anti-VEGF medication injected into the eye or less commonly laser coagulation or photodynamic therapy may slow worsening. Supplements in those who already have the disease may slow progression.

Zeaxanthin is the predominant carotenoid in the macula, which helps protect your central vision. Unfortunately, Zeaxanthin is hard to get through the average daily diet. This brief video explains the effects of Zeaxanthin and how to obtain Zeaxanthin for healthy macular pigment and healthy vision.
http://www.ihealthtube.com Both are known as powerful antioxidants important for eye and brain health. Dr. Jim Stringham discusses both as well as which is more prevalent when it comes to both the eye and brain.
http://PreserveMacForte.com Zeaxanthin is found in the macula and it protects your eyes against damaging blue light, which may help you fight macular degeneration. Age related macular degeneration (AMD) is the leading cause of blindness in older adults. Macular degeneration prevention is a debatable topic and one that not all experts agree upon. There is also no known treatments for dry macular degeneration and it is recommended by most eye care specialists to supplement your diet with a daily vitamin containing specific antioxidants shown to slow macular degeneration.
