What percentage of blue light is blocked at each of the wavelengths 380nm to 490nm?

Hi and thank you for your question! The Vizomax anti-blue light filter for computer monitor blocks 100% of the blue light between 380nm to 490nm. Please, let us know if you have more questions! Kind regards, Meryl

anti-blue light screens are clear. no tint. yet anti-blue light glasses are mostly all tinted yellow. is there a reason why

Hi Dena, Thank you for your question! Our anti-blue light TV Protectors are clear as well as we have used the latest anti-blue light technology when creating them. It depends on the brand & manufacturers whether an anti-blue light protector is yellow tinted or not. The quality doesn't depend on this you can rest sure about it. Kind regards, Meryl
