Study Demonstrates Role of Zeaxathin in Eye Health

Research performed at Schepens Eye Institute and the Department of Ophthalmology, Harvard Medical School, has established that dietary zeaxanthin plays an essential role in protecting the retina of the eye from the damaging effects of light and may help prevent age-related macular degeneration (AMD). From the many carotenoids in the diet, the human retina selectively accumulates only two: zeanxanthin and lutein, and they are known as the macular pigment because their concentration in the macula is so high. Becaue these carotenoids absorb blue light and because they are powerful antioxidants, scientists have hypothesized that they protect the retina.
