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

If you have not 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 will find how much you love wearing them when facing digital screens for an extended time. With FEIYOLD Blue Light Blocking Glasses, you will no longer experience eye fatigue or headaches.

To demonstrate the effectiveness of these glasses, use the blue light torch to beam 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 has turned purple, while the area shaded by the FEIYOLD Blue Light Blocking Glasses has not turned purple. This clearly shows that FEIYOLD blue light glasses can effectively block most of the harmful blue light, thereby protecting your eyes.

You can now enjoy your digital activities without worrying about the damaging effects of blue light. The pictures from the website, however, cannot determine whether the glasses have any anti-blue light coating. These online tests are designed for orange-colored sleep glasses, which work by removing the entire blue spectrum and turning your vision orange.

One of the key features of FEIYOLD Blue Light Blocking Glasses is their adjustability. If the legs sit unevenly, you can easily bend them or adjust the bridge to change the shape of the frame, ensuring a comfortable and proper 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, making it a comfortable and durable choice.

Prolonged exposure to blue light can cause eye fatigue, blurred vision, and headaches. With FEIYOLD computer glasses, you will notice a difference in just a few days. These glasses effectively block the most harmful blue light from your computer, phone, and TV, providing much-needed protection for your eyes.

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

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.

To make it even more convenient, FEIYOLD offers two pairs of glasses at a great price. You can keep a pair in each of your reading areas or share one with a friend or family member. It's an economical and practical solution for protecting your eyes and those of your loved ones.

FEIYOLD stands behind its product, and they are dedicated to providing worry-free service. If you encounter any issues with your purchase, simply reach out to them, and they will be there to solve your problems. There is no risk for you to try these remarkable blue light blocking glasses.
