Me (and many other people) experience eye-ache from new Macbooks (and windows machines).
I have spent two years of trial-and-error and found that installing macOS Mavericks on my MacBook (pro 13 late 2013, Intel Iris 1536 MB) resolves the issue of eye ache completely. (it is believed that newer systems use harsher version of temporal dithering that causes of a certain group of indivisuals eye aches).
I cannot stay at Mavericks because of software support and security issues, so the only thing is an issue now:
How can I take drivers from Mavericks and install them on Catalina? (I tried replacing .kext in /System/Library/Extensions with old files but it didn't work).
I'm struggling with installing driver of my graphic adapter on high Sierra but till now I failed to find a solution to my issue ....
My PC configuration is .
CPU : AMD A8-5500 APU with integrated Radeon 7560
RAM : 8G
I tried to download a tool from tonymax website and after I used it I unable to login to my Mac high Sierra so I installed high Sierra again .....
