Retro Round Anti Eyestrain Computer Gaming Glasses for Women/Men (2Pack)

If you haven't worn blue light blocking glasses before, you may need an adjustable period of 2-3 days to get accustomed to them. During this adjustment period, you may experience some discomfort. However, once you get used to them, you'll find that you love wearing them when facing digital screens for long periods of time. With FEIYOLD Blue Light Blocking Glasses, you'll experience no eye fatigue and no headaches.

To test the effectiveness of these glasses, you can use a blue light torch to beam the sensitive area of the blue light testing card, as shown in the first picture. The part of the testing card that is beamed by the torch will turn purple, while the part shaded by the FEIYOLD Blue Light Blocking Glasses will not turn purple. This demonstrates that FEIYOLD's blue light glasses can effectively block most of the harmful blue light, protecting your eyes.

You can enjoy your digital time without worrying about the damaging effects of blue light. The pictures from the website may not be able to determine whether the glasses have anti-blue light properties, as these online tests are designed specifically for orange-colored sleep glasses that remove the entire blue spectrum, turning your vision orange.

Once 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 and even fit. The lightweight TR90 frame is designed for all-day wear, without putting any stress on your nose. It is flexible, bendable, and shock-resistant.

Prolonged exposure to blue light can cause eye fatigue, blurred vision, and headaches. With our computer glasses, you'll notice a difference in just a few days, as they effectively block the most harmful blue light from your computer, phone, and TV. The 3A transparent lens not only blocks 99% of the harmful blue light spectrum (400-440nm), but also allows for high transmittance (93%), providing a perfect balance between eye protection and visual experience.

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

Buying a pair of FEIYOLD Blue Light Blocking Glasses is an economical and convenient solution. Keep a pair in each of your reading areas, or share one with your friend or family member. It's the perfect gift for your parents, friends, and any seniors in your life, as well as yourself.
