Nutrition and Vitamins for Your Eyes
Learn how diet and nutrition play an important role in the health of your eyes in this series of informative articles written by experts in vision and eye health.
Who doesn't want to enjoy a lifetime of excellent vision?
But besides having routine eye exams and having your eyeglasses prescription and contact lens prescription updated when changes occur, is there anything else you can do to keep your eyes healthy and maintain optimum vision?
According to nutrition research, an important key to healthy eyes and good vision may be getting enough carotenoids in your diet. In particular, carotenoids may help protect your eyes from the damaging effects of blue light and reduce your risk of macular degeneration later in life.
What Are Carotenoids?
Carotenoids (kuh-RAH-teh-noids) are pigments that give fruits and vegetables their vibrant red, orange, yellow and green colors. They act as antioxidants and have significant cancer-fighting properties.
How Do Carotenoids Work To Keep Eyes Healthy?
The most sensitive part of the retina in the eye is called the macula. The macula has the highest concentration of photoreceptors in the retina and is the portion of the retina where our sharpest vision is produced. It also is responsible for our ability to perceive colors.
Three dietary carotenoids — lutein, zeaxanthin and meso-zeaxanthin — form the pigment in the macula ("macular pigment") that protects the millions of photoreceptor cells located in this small region of the central retina.
In particular, the antioxidant and anti-inflammatory properties of the macular pigment reduce oxidative stress on the retina caused by high-energy blue light, which is believed to contribute to the development of macular degeneration.
Also, blue light has shorter wavelengths than other visible light, which scatter more easily in the eye, causing glare and reducing contrast sensitivity and visual acuity. The macular pigment selectively filters out image-degrading visible blue light for sharper vision.
Which Foods Contain Eye-Healthy Carotenoids?
Foods with the highest concentrations of lutein and zeaxanthin found in macular pigment include:
Leafy greens such as kale, spinach, Swiss chard and turnip greens are excellent natural sources of eye-healthy carotenoids.
• Swiss chard
• Mustard greens
• Turnip greens
• Green peas
How To Boost Your Diet And
Nutrition To Protect Aging Eyes
Age-related eye diseases such as macular degeneration and cataracts commonly cause impaired vision and blindness in older adults. But lifestyle changes, including good nutrition, could help delay or prevent certain eye problems.
Besides adopting a healthy diet, you can help protect your eyes by avoiding prolonged exposure to ultraviolet (UV) rays and high-energy blue light, quitting smoking and getting annual eye exams.
During a dilated eye exam, your eye doctor can carefully examine the health of your eyes and check for eye diseases such as macular degeneration, glaucoma and diabetic retinopathy. Detecting these conditions early may help prevent permanent vision loss.
Diet, Antioxidants And Healthy Eyes
Diet is an extremely important part of the daily lifestyle choices you make. Foods you eat and the dietary supplements you take affect your overall health as well as the health of your eyes.
Eat plenty of colorful fruits and vegetables for optimum eye health.
A diet high in saturated fat and sugar may increase your risk of eye disease. On the other hand, healthy foods such as greens and fruits may help prevent certain eye diseases and other health problems.
Cardiovascular disease, diabetes and eye conditions including cataracts and age-related macular degeneration (AMD) have been shown to occur less frequently in people who eat diets rich in vitamins, minerals, healthy proteins, omega-3 fatty acids and lutein.
All healthy diets should include ample amounts of fresh, colorful fruits and vegetables. In fact, experts recommend that you consume at least five to nine servings of these foods daily.
Choose dark green or brightly colored fruits and vegetables to obtain the most antioxidants, which protect your eyes by reducing damage related to oxidizing agents (free radicals) that can cause age-related eye diseases.
Lutein and zeaxanthin are plant pigments called carotenoids that have been shown to protect the retina from oxidative changes caused by ultraviolet light. Spinach and kale are excellent food sources of lutein and zeaxanthin, which are also found in sweet corn, peas and broccoli.
Vitamin A, vital for healthy vision, is found in orange and yellow vegetables such as carrots and squash. Fruits and vegetables also provide essential vitamin C, another powerful antioxidant.
