Beta Carotene Pills May Not Save Vision, Brigham and Women's Hospital Study Finds
Carrots, rich in beta carotene, long have been thought to sharpen eyesight, but a new study suggests that beta carotene pills are powerless against a common type of vision loss among older people. Age-related macular degeneration is the leading cause of blindness in people 65 and older. The condition blurs the center of the field of vision, making it difficult to read, drive, thread a needle and even recognize faces. It affects more than 10 million Americans and there is no cure.
