The carotenoid xanthophylls lutein and zeaxanthin have been shown to offer protection from age-related macular degeneration, a disease of the eye that can lead to blindness. Now researchers at Ohio State University have revealed that the nutrients can also help prevent cataracts.
In the current study, reported in the December 2004 issue of the Journal of Nutrition, human eye cells were treated with several concentrations of lutein, zeaxanthin or vitamin E, and exposed to ten seconds of ultraviolet-beta radiation (UVB). Ultraviolet-beta radiation is a wavelength of sunlight that is believed to be responsible for cataract formation. An additional group of cells was not pretreated.
