Blue Light Blocking Glasses for Women/Men, Retro Round Anti-Eyestrain Computer Gaming Glasses (2 Pack)

Product Description If you have never worn blue light blocking glasses before, it is important to note that there may be an adjustment period of 2-3 days. During this time, you may experience some discomfort. However, once you get used to it, you will appreciate the benefits when you spend a long time in front of a digital screen. No eye fatigue, no headaches.

To test the effectiveness of FEIYOLD Glasses, use the blue light torch to shine on the sensitive area of the blue light testing card, as shown in the first picture. You will notice that the part of the testing card exposed to the torch turns purple, while the part shaded by FEIYOLD Blue Light Blocking Glasses remains unaffected. This demonstrates that FEIYOLD blue light glasses can block a significant amount of the harmful blue light and protect your eyes. Now you can enjoy your digital time without worrying about the harmful effects of blue light.

Please note that online pictures cannot determine whether the glasses have anti-blue light properties. These online tests are specifically designed for orange sleep glasses, which work by removing the entire blue spectrum, resulting in a completely orange vision.

If the legs of the glasses are uneven, you can bend them or adjust the shape of the frame to ensure a proper fit. The lightweight TR90 frame is designed for all-day wear, providing flexibility, bendability, and shock resistance, without putting stress on your nose.
