Idk, my eyes start to hurt if there's too much blue light in the environment (fluos are the worst). Screen blue light isn't nearly as bad, but a filter still makes it more comfortable.
It could make you less "over concentrated " thus reduce eye strain and stress. As if sitting in comfy room with warm colors. It's just speculation though.
I've tried this several times, but I'm always afraid I'll forget it's on when doing colour-sensitive work (e.g. editing photos). Your eyes adjust to the difference somewhat (so that at one point the yellow starts feeling neutral), but things would still be off in the end.
That part sucks. You definitely need a non-altered screen for that. I've probably made some less attractive color choices now that you've reminded me haha.
