Lutein and Zeaxanthin for Vision

Date : 2018-5-25 9:40:03 Views :

Why Are Lutein and Zeaxanthin Good for Your Eyes?

Not only can you find these potent antioxidants in many vegetables, they are also in your eyes, especially the lens, retina, and macula. That’s why doctors believe they play a key role in healthy vision.

How Do They Help?

Lutein and zeaxanthin protect your eyes from harmful high-energy light waves like ultraviolet rays in sunlight. Studies suggest that a high level of both in eye tissue is linked with better vision, especially in dim light or where glare is a problem.

Diets rich in these two nutrients may help hold off age-related eye diseases. For example, one study found that people who ate foods rich in zeaxanthin -- think “green veggies” like spinach, kale, and broccoli -- may be half as likely to get cataracts. Another showed that if you have macular degeneration, which causes damage to the middle of your retina and can take away your central vision, supplements with lutein and zeaxanthin can slow its progress. Eye doctors have a test they use to measure the level of these nutrients in your eye.
