Brief Summary
Vision at twilight and night is more difficult and dangerous for the entire population, even more so for the elderly and especially for the elderly with degenerative disease. Multiple worldwide laboratories have demonstrated the ability to raise macular pigment optical density with dietary carotenoids. This proposal further evaluates the relationship between macular re- pigmentation and vision under stressed conditions simulating twilight and night driving.
