Product Description
If you haven’t worn blue light blocking glasses before, you may need an adjustable period of 2-3days.
During this adjusting period you may experience discomfort.
Just keep it, and you will find how you love it when you facing digital screen for a long time.
No eye fatigue, no headache.
Use the blue light torch to beam the sensitive area of blue light testing card and FEIYOLD Glasses as shown in the first picture. We can see that the part of testing card beamed by the torch has turned purple, and the other part shaded by FEIYOLD Blue Light Blocking Glasses has not turned purple.
Thus we can see, FEIYOLD blue light glasses can block most of the useless blue light and protect your eyes. You can enjoy your digital time without worrying about the hurting from blue light.
Note:
The pictures from website are unable to demermine whether there is anti-blue light on the glasses. These online tests are designed for orange colored sleep glasses only. Orange glasses work by removing the entire blue spectrum, turning your entire vision orange.
