Your vision is important, and the foods you eat may help to keep your eyes healthy. Your eyes require vitamin A for normal vision, and research indicates that nutrients such as vitamin C, vitamin E, beta carotene (vitamin A precursor) and an antioxidant called lutein may help to reduce the risk of advanced age-related macular degeneration -- a leading cause of blindness in the elderly. Other studies suggest that omega-3 fatty acids may help protect eyes from retinal degeneration and ease the discomfort of dry eyes.
The researchers used large amounts of nutrients in these studies -- similar to what you may find in specially formulated dietary supplements. However, there are some superfoods that are high in some of these eye-protecting nutrients and pack a powerful nutritional punch.
