Serious question - Couldn't you just use f.lux (the software program) to remove or tamper the same spectrum that these glasses are supposed to filter to achieve the same effect?
vpr555Not really. The overall color would be the same, but the spectrum wouldn't. This is a phenomenon called metamerism if you want to look it up. TL;DR : same color can be the result of many different spectrum. What is important for eye strain is spectrum.
