I always hated the bright background on computers. The green or amber old PC screens were better. The first program for inverting the colors I wrote on my first homecomputer, Atari ST. Since then I always look for something handy to switch to dark mode on my computers, even if they don't have a built in way of doing it. The one I'm using now is f.lux, working good enough for me. I can let it run normal colors when I start up some art program so I get correct colors and automatically switch back to red when I go to the darkmode editor. I also make sure I turn down the brightness on the screen as much as possible since that is a bright lamp shining at you for 8 hours per day. My eyes are deteriorating with age too so this is getting more and more important. That blue light is not good for your retina. There are glasses with filter so you get the blue filtered out everywhere, might be something to look into soon I guess.
