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

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 adjusting period, you may experience some discomfort. However, once you get used to it, you'll find how much you love them when facing digital screens for an extended period.

These glasses can effectively reduce eye fatigue, headaches, and other issues associated with prolonged exposure to harmful blue light. To demonstrate their effectiveness, you can use a blue light torch to shine on the sensitive area of the blue light testing card, as shown in the first picture. You'll notice that the part of the testing card exposed to the torch turns purple, while the section shaded by the FEIYOLD Blue Light Blocking Glasses remains unaffected.

This visual test clearly shows that FEIYOLD blue light glasses can block most of the harmful blue light, providing protection for your eyes. You can now enjoy your digital activities without worrying about the damaging effects of blue light.

It's important to note that the online tests available may not be able to determine the presence of anti-blue light features on the glasses. These tests are typically designed for orange-colored sleep glasses, which work by removing the entire blue spectrum and turning your vision orange. With FEIYOLD blue light blocking glasses, the lenses are transparent, allowing for a more natural visual experience while still providing effective protection.

The FEIYOLD glasses feature a lightweight TR90 frame designed for all-day wear without causing stress on your nose. The frames are flexible, bendable, and shock-resistant, ensuring a comfortable and secure fit. If the legs sit unevenly, you can simply bend them or adjust the bridge to change the shape of the frame, ensuring it sits properly on your face.

The 3A transparent lenses not only block 99% of the harmful blue light spectrum (400-440nm), but also maintain a high transmittance of 93%, providing a perfect balance between eye protection and visual clarity. This makes the FEIYOLD glasses an excellent choice for extended use on computers, phones, and TVs.

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

For your convenience, the FEIYOLD blue light blocking glasses are available in a set of two pairs 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.

The FEIYOLD team stands behind their product and offers a worry-free service. If you encounter any issues with the glasses, please don't hesitate to contact them, and they will be there to resolve your concerns. There is no risk in trying these blue light blocking glasses, as they are designed to provide you with a comfortable and protected digital experience.
