Blue Light Blocking Glasses for Women and Men

If you haven't worn blue light blocking glasses before, you may need an adjustable period of 2-3 days to adapt. During this adjusting period, you may experience some discomfort. However, once you get used to it, you'll find how much you love the glasses when facing digital screens for an extended time. No more eye fatigue or headaches.

Use the blue light torch to beam the sensitive area of the blue light testing card and the FEIYOLD Glasses as shown in the first picture. You'll notice that the part of the testing card beamed by the torch has turned purple, while the area shaded by the FEIYOLD Blue Light Blocking Glasses has not. This demonstrates that the FEIYOLD blue light glasses can effectively block most of the harmful blue light and protect your eyes. You can now enjoy your digital activities without worrying about the damaging effects of blue light.

Please note that the pictures from the website cannot determine whether there is any anti-blue light coating on the glasses. These online tests are designed for orange-colored sleep glasses only, which work by removing the entire blue spectrum and turning your vision orange.

If the legs of the glasses sit unevenly, you can easily bend them or adjust the bridge to change the shape of the frame, ensuring a comfortable, non-crooked fit. The lightweight TR90 frame is designed for all-day wear without stress on the nose, providing flexibility, bendability, and shock resistance.

Prolonged exposure to blue light can cause eye fatigue, blurred vision, and headaches. You'll notice a difference in just a few days of using our computer glasses, as they block the most harmful blue light from your devices, such as computers, phones, and TVs.

The 3A transparent lenses not only block 99% of the harmful blue light spectrum (400-440nm), but also maintain a high transmittance of 93%, striking a perfect balance between eye protection and visual experience. The lightweight and durable TR90 frames ensure comfort for long periods of wear.

Prolonged exposure to blue light can also slow or stop the production of melatonin, leading to sleep disorders. The FEIYOLD Blue Light Shield can protect you and provide you with a better night's sleep.

Buying two pairs of these glasses at a great price is economical and convenient. Keep a pair in each of your reading areas, or share one with a friend or family member, especially seniors in your life.
