You know the age-old idea of eating carrots to maintain healthy eyes? Well, there is a reason for it. Beta-carotene is an important anti-oxidant that keeps eyes working correctly, and happens to be responsible for the orange color of carrots and other produce. Beta-carotene is converted to Vitamin A in your body which is used in the process of converting light into the actual images you see, and keeping your cornea moist.
This antioxidant is easy to find: carrots, apricots, cantaloupes, peaches, blueberries, sweet potatoes, winter squashes, and most of the dark green leafy vegetables.
