Do you have dark mode ON all day? Ever use the tiny suspender Chromium extension?
No, I tried some Linux prog once, red shift I think it was, and it did help a bit I guess, but then bought the glasses, and it fixed my eye strain tearing, stinging etc. So I never put anything on agsin to dim the blue lights (I’ve since rei stalled many times several os’s, so never got around to using any kinds of dark mode or blue light suppressors. )
