Retro Round Anti Eyestrain Glasses for Women and 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 adjusting period, you may experience some discomfort. However, once you get used to it, you'll find how much you'll love them when facing digital screens for an extended time. No more eye fatigue or headaches.
To demonstrate the effectiveness of FEIYOLD Blue Light Blocking Glasses, use the blue light torch to beam 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 has turned purple, while the area shaded by the FEIYOLD glasses has not. This clearly shows that FEIYOLD blue light glasses can block most of the harmful blue light, effectively protecting your eyes.
You can now enjoy your digital activities without worrying about the detrimental effects of blue light. It's important to note that the online tests designed for orange-colored sleep glasses cannot determine the anti-blue light properties of other glasses. Unlike those orange glasses, which work by removing the entire blue spectrum and turning your vision orange, FEIYOLD glasses are designed to block only the most harmful blue light wavelengths (400-440nm) while maintaining a high transmittance (93%), providing a perfect balance between eye protection and visual experience.
The lightweight and durable TR90 frames of the FEIYOLD glasses are designed for all-day wear without causing any stress or discomfort on your nose. If the legs sit unevenly, you can easily bend them or adjust the bridge to change the shape of the frame, ensuring a perfect fit.
Prolonged exposure to blue light can not only cause eye fatigue, blurred vision, and headaches but can also slow or stop the production of melatonin, leading to sleep disorders. FEIYOLD Blue Light Shield can protect you from these issues and provide you with a better night's sleep.
To make it more convenient and economical, 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, especially seniors in your life.
We believe in the quality of our product, and we stand by it. If you encounter any issues with the FEIYOLD Blue Light Blocking Glasses, please don't hesitate to contact us. We'll always be here to solve your problems, and there's no risk for you to try them out.
