You drink milk for strong bones and avoid salt to promote a healthy heart. But what can you eat to keep your vision sharp? According to the American Optometric Association, there is a whole menu of options:
Green leafy vegetables, such as spinach, and eggs are good sources of lutein and zeaxanthin. Studies show these nutrients reduce the risk of age-related macular degeneration and cataracts.
The vitamin E found in nuts, fortified cereals and sweet potatoes is thought to protect eyes from the damage caused by free radicals, or unstable molecules that break down healthy tissue.
Omega-3 fatty acids - most readily found in fish oil - are important for proper visual development and retinal function.
Meats, dairy products, beans and whole grains are rich in zinc, which helps facilitate the production of melanin, a protective pigment in the eyes.
