Same symptoms like mine. Try to find some old laptops and check. You have to find perfect combination of hardware, os and softwares. You need to try lots of combinations and come up with the setup works for you. For starters try to find very old system and test your eyes.
Once you found it, keep it safe. Turn off all software updates. Create system restore point on that place. After that any software installation even for personal use, create a restore point before doing it. you should have options to go back whenever you got the eye strain back.
For office system, ask your system administrator/IT dept to provide remote access to the system and access it from your personal system as remote access. That way your screen, hardware and graphics drivers will be a good one but core PC will be that of your office one.
