I've had some similar experiences... in that I was pretty much A-OK on Windows 10 all the way up to 1909 and a bit. Something changed a while after I updated to 1909 and I was getting eye strain. (I tried installs of Win 7 and Win 10 and they all exhibited the same problem). Then a while later the problem just went away. I've never been able to explain it.
True, I did get my prescription updated around the same time so that may have had something to do with it - but then I was not having any problems with my good laptop.
Now, my Win 10 machine is all good - and it's my good (for years!) Macbook that has gone bad. Same Macbook screens, cables etc etc and there have been NO major updates installed but it's all giving me eye strain.
This stuff is just utterly confounding. That said, I am a bit suspicious about my prescription and whether things have changed there - but I can't get it checked as we're in lockdown.
