> I never understood their use as computer glasses because all computers and phones have low blue light modes now and these do what they say they do, and I've measured the output of screens with a spectrophotometer. Anecdotally, when I first had "anti-blue-light computer glasses" many years ago, nor windows nor mac os had the "night mode" feature. Run-of-the-mill monitors didn't have it, either, instead sporting an extremely blueish image. I don't know that my glasses helped with sleep, but they sure as hell made the screens more pleasant to look at. And no, fiddling with the monitor settings didn't really help. I'm talking about your standard crappy enterprise monitors, with abysmal contrast, so that if you lowered the brightness or some such you couldn't make out anything anymore on them.
