I really identify with your situation and sometimes I wish there was a name for this, like a disease, so we could have help from the state and some investigation going. It's awful what is happening to us, really is.
I haven't found a computer that I can use since my old one, a laptop with 13 years, just stop working for various reasons. I've tried different settings, software and hardware to no good results even if some stuff is better than others. What I found most useful was the dasung paperlike e-ink monitor and I've been writing with it connected to a windows 10 laptop. when I need to Check something with color I turn on the laptop screen, see it for a couple minutes and then return to the dasung monitor. it's expensive but they are the only company in the world doing it…
I also tried cover one eye, in the first hour seemed to help but then I go eye strain and headaches all the same.
I found that also helps me to have the monitor really far away or connected to an old crt TV which is not good for writing but only for video calls or watching duff.
Windows 11 is coming do you guys think it will be better or worse?
at some point someone who works at these companies will have the same problem has us, no? and point to their attention that something is not OK. I find people always complaining of eye strain and headaches much more in the last couple of years…
tech should become better not worse, I really don't get it.
Also I've been using a typewriter just to do drafts of texts and then do the final edit on the computer and I must tell you what a relief… it's like not having anything distracting you from you thought process. you write and then it appears on paper, it's there. I know it's not a viable option for office work now a days but at least for drafts and sketchs it works well, and then you can scan it and Send it also ahah. (new dorm of email?, just kidding).
hope you find a solution, all the best
