Guest article today by Dr. David Cronauer, Doctor of Optometry.

Can you imagine what it would be like not to be able to see, or to have a dramatically reduced visual ability? There are so many things we take our sight for and yet we do very little to protect our eyes and keep them healthy! Fortunately, there are some easy ways to make sure your eyes get the protection they need to stay strong throughout your life. This post will focus on five key nutrients that will keep your eyes healthy and help avoid the development of eye damage, such as cataracts or glaucoma.

1. Vitamin A. Do you remember hearing that carrots are good for your eyes? That is because carrots are an excellent source of Vitamin A, which plays a key role in vision as well as in cell reproduction and healing. Vitamin A helps you see well in the dark, and a deficiency in this vitamin often causes blindness in third-world countries. In addition, vitamin A helps the immune system. Other than carrots, an excellent source of vitamin A is liver. Nutritional supplements can also provide this important element. Be careful, though, as large doses of vitamin A can be toxic.
2. Vitamin C.Vitamin C has been linked to the prevention of cataracts. Studies show this is most effective over a long period of time, so start focusing on this today! It can also reduce eye pressure in glaucoma patients, easing the stress on their vision. Excellent sources of vitamin C include many fruits, such as oranges, watermelon, grapefruit, and strawberries.
3. Vitamin E. Vitamin E is an antioxidant that protects body tissue from cell damage cause by free radicals. Intake of this vitamin can help protect your eye from many diseases associated with aging. Good sources of vitamin E include nuts, nut oils, and green leafy vegetables.
4. Lutein. Lutein is a carotenoid that can protect your eyes from light-inflicted damage. While sunlight is an important nutrient in itself, certain frequencies within the sunlight can be damaging to your eyes. Leafy green vegetables are a good source of lutein, and you can also find supplements that provide carotenoids.
5. Sunlight! Many of us spend the majority of our days indoors, often in front of a computer. Extended periods of time looking at a computer screen and in unnatural light can be very damaging for your eyes. Be sure to take frequent breaks, focus your eyes on a variety of distances, and try to get at least one hour of natural sunlight each day.

We all want to make sure we stay healthy as long as possible. As you take care of your muscles, cholesterol, joints, and bones, don’t forget to also nurture your eyes. They will serve you well throughout life if you make sure they receive the nutrition and care they need.
