Blue light blocking capacity test
Use the blue light torch to beam the blue light testing card and Cyxus glasses as shown in the first picture.
We can see that one part of the testing area directly beamed by blue light has turned blue, and the other part shaded by Cyxus Glasses has not turn blue.
Thus we can see, Cyxus blue light filter glasses can block most of the harmful blue light and protect your eyes. With Cyxus glasses, you feel free when facing digital screens.
