vision quest Cataracts and age-related macular degeneration (AMD) are the two leading causes of blindness and visual impairment among millions of aging Americans. Add to that excessive screen time in a digital age that is causing eyes to age faster in a younger population. Retinal damage and eye strain is showing up in younger adults, from constant exposure to blue light from computers, phones, tablets, and TVs. While blue light can be good, the amount of time people spend close to screens is cause for concern. Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells, which can result in AMD. Fortunately, research has shown us that nutrition can impact these conditions as well as the overall health of our eyes. Here are some of the key nutrients and herbs that can help keep your eyes seeing their best, both now and as you age.
Nutrients
The Age-Related Eye Disease Study (AREDS), which followed 3,600 adults, showed that people may benefit from vitamins C and E, beta carotene, zinc, and copper to reduce the risk of vision loss caused by intermediate to advanced macular degeneration. Another study found that people consuming plenty of A, C, and E vitamins, by eating fruits and vegetables or by taking a supplement, decreased their risk for developing cataracts by 37 percent. Vitamin C is of particular importance because it is the major antioxidant in the lens of the eye.
Carotenes
Lutein and zeaxanthin are natural carotenes found in green leafy vegetables like spinach and kale, as well as egg yolks and broccoli. Lutein is concentrated in the macula of the eyes, and together lutein and zeaxanthin 24
help to protect against harmful blue light. Studies show that people who supplement with lutein have a 57 percent lower risk of macular degeneration. Beta carotene, a common carotene found in sweet potatoes and carrots, converts to vitamin A in the body and is also essential for healthy eyes.
Herbs
One of the most well-known herbs for the eyes is bilberry, a cousin to the American blueberry. Bilberries and blueberries are rich in anthocyanins, plant compounds that strengthen the walls of the small capillaries leading into the eye, that promote healthy circulation, and that act as antioxidants to protect against free radical damage to the eyes. Studies have shown that bilberry extract can help enhance the ability to focus, fight visual fatigue, and support nighttime vision. For optimal eye health, using a combination of different antioxidants often gives the best results. Take care of your eyes and you’ll see the difference, both now and later in life! ●
