Cataracts - Risk Factors

(Page 2)

Lutein and zeaxanthin are the two carotenids that have been most studied for cataract prevention. They are xanthophylis compounds, which are a particular type of carotenid. Lutein and zeaxanthin are found in the lenses of the eyes. Some evidence indicates that xanthophyll-rich foods (such as dark green leafy vegetables) may help retard the aging process in the eye and protect against cataracts. However, there is not enough evidence to suggest that taking supplements that contain these carotenoids lowers the risk for cataract formation.
