Did you know that every time you watch TV, use your smartphone, or work on your computer, your eyes are exposed to blue light? Blue light has a short wavelength and carries a lot of energy, and studies suggest that prolonged exposure to it may potentially be harmful.

Why is Blue Light a Concern Now?

We've always been exposed to some blue light from the sun, digital screens, electronic devices, and fluorescent lighting. However, with the increasing use of LED back-light technology in TVs, computers, smartphones, and tablets, we're now exposed to more sources of blue light for longer periods than ever before.

The Vision Council found that over 83 percent of Americans use digital devices for more than two hours daily, with more than 60 percent experiencing symptoms of digital eyestrain. Fortunately, there are strategies to help protect your eyes from these issues.

How Can Lutein and Zeaxanthin Help?

To defend against blue light and digital eyestrain, limit your screen time and consider supplementation with premium quality lutein and zeaxanthin. These carotenoids accumulate in the retina, especially in the macula responsible for central vision.

Lutein and zeaxanthin act as a filter, giving your macular pigment its yellow color and shielding your eyes from the negative effects of blue light. They also protect your eyes from oxidative stress caused by high-energy light.

Are Supplements Effective?

Yes! A major NIH study in 2001 showed that nutritional supplements, including lutein and zeaxanthin, can preserve macular health. A follow-up trial revealed that taking 20 mg of lutein daily for one year increased the density of the macular pigment, acting like internal sunglasses against blue light.

How Much Should You Take?

While aging brings changes to the eyes, you can support eye health with nutrition. Foods rich in lutein and zeaxanthin include kale, winter squash, spinach, turnip greens, collard greens, and Swiss chard. Consider supplementing with 20-40 mg of lutein, 4–8 mg of zeaxanthin, and 25 mg of zinc daily.
