Cataracts and Age-Related Macular Degeneration are the leading causes of visual impairment in the United States. Nutrition is one promising way to delay or prevent the progression of these diseases. Proper nutrition is critical for preserving vision throughout your lifetime. No doubt you have heard that carrots can improve your vision, but other powerful antioxidants and nutrients such as Lutein, Vitamin C and Omega-3 Fatty Acids can also improve your eye health and reduce your risk of cataracts and Age-Related Macular Degeneration.
Lutein and Zeaxanthin are nutrients found in eggs and leafy greens such as kale, broccoli and spinach among many other vegetables. These antioxidants filter harmful blue energy wavelengths of light and help protect healthy cells in the retina and reducing the risk of Age-Related Macular Degeneration. If you are not getting enough of Lutein and Zeaxanthin in your diet, you can also take daily supplements such as Ocuvite.
Vitamin C is a powerful antioxidant that promotes healthy skin, bones and eyes. Long term consumption of Vitamin C may reduce the risk of Cataracts. A Cataract is defined as the clouding of the normally transparent lens of the eye. When the lens becomes opaque, blurred vision may result. Although cataract development is part of aging, oxidative stress can promote the damage of certain proteins in the lens which leads to the lens becoming progressively more cloudy over time. Oxidative stress resulting from free radicals originates from UV radiation, pollution, and smoking. Antioxidants such as Vitamin C safely react with free radicals and terminate the chain reaction that leads to damaged molecules in the eye. Excellent natural sources of Vitamin C include red peppers, berries, citrus fruits and tomatoes.
Furthermore, Omega-3 Fatty acids also play an important role in maintaining proper eye health. Without the proper kinds of fat in our diet, our eyes may suffer. A diet rich in Omega-3 Fatty acids can reduce the risk of developing Dry Eye Syndrome and Macular Degeneration. To maintain eye comfort and good vision, the front surface of the eye must be covered with even layers of quality water and oils. Omega-3’s can improve the eyes oil film, which is produced by small glands on the eyelid, called meibomian glands. Foods rich in Omega-3’s include catfish, halibut and salmon.
