I’m sceptical that blue light lenses, even those that effectively block blue light, are doing much of anything. Blue light can mess with your circadian rhythm, but so can orange-tinted light if it’s bright enough. A better system would be to limit screen time after dark. If you are using screens, lower their brightness to the lowest amount you can still see. You can use a night -time filter to tint the screen orange after dark (most OS’s and devices support some form of this). Blue light lenses while holding a OLED device six inches from your face at full intensity? Likely not doing much.
I thought about this before, and mostly agree. My mom knows nothing about computers and could probably use Ubuntu if I stick it on a machine and gave it to her. The thing preventing me from doing it is that when things go wrong in Linux, it often requires extensive terminal usage to fix. And my mother can often find new and creative ways to break a computer. If something went wrong with it, I would have to fix it. There is literally no one else she knows who would even know where to start. At least if she’s on windows, she can find someone to help her.
