![]() Sadly, many companies offer products for which they claim blue light blocking properties, without showing their spectral transmission properties. Thanks!Įxcept with a spectrogram, it is very difficult to define a filter’s spectral transmission properties. ![]() ![]() Some of the links below are also commission links, as disclosed. With the help of a few spectrograms you’ll see below why it is possible to say deceivingly – but without lying – that blue blockers don’t distort color.ĭisclaimer: My interest in blue light filters comes from my problems with light sensitivity (photophobia), discomfort glare, and computer eye strain.ĭisclosure: You can support GLARminY – at no additional cost to you by “ donaing” a small percentage of anything you buy from Amazon by accessing Amazon through this link ( commission link). Such a blue light filter necessarily distorts color! ![]() a filter should block either most blue light or considerably more blue light than it blocks other, longer wavelengths of visible light. But to prevent or mitigate eye strain, glare, insomnia, etc. Saying that “ blue light blockers don’t distort color” is manipulation used to convince uninformed people to buy products that filter blue light, but not much and not any more than it filters the rest of visible light spectrum.
