You can try some older driver and disable current graphic driver. You can try set Windows 7 as close to Windows XP There are several ways you can try that your eyes would get some reliefe. I am really sad that windows XP is deprecated because I would never ever switch to higher Windows due to problems with eyes.
When I use windows 7 my eyes start to get sore right a way and after a few hours I feel pain and can not work normally. I can work on computer for more than 11 hours a day and no problem with eyes. On windows XP I have no problems with eyes at all. On the same hardware I have installed old windows XP and windows 7.
I guess our eyes are sensitive to something whitch was introduced with windows 7 arrival or perhaps already when Vista arrived. Many people who switched from XP to windows 7, 8, 10 have similar problems and many people do not have this problems at all. XFAUSTx have you already found solution to your problem?
