Yes: Lutein (which you can only get into your system through your diet) is a carotenoid, but unlike beta carotene, does not convert to vitamin a in the body. Zeaxanthin and lutein are the only carotenoids known to concentrate specifically in the eye. They are believed to help filter damaging light and prevent free radical damage to the delicate structures in the back of the eye.
