u could get your eyes checked at specsavers or whatever, it is not very expensive, they take a scan of the eye and they can see if something is up with it or even if u need glasses ofc. if u need glasses f.ex u will compensate, so your eyes get tense cause u try to focus all the time instead of beeing more relaxed when looking, i can do just fine so long im not on pc or phone but, absolutelty need them if i am on pc or phone over extended time. i switched to a ips after a good while with va, no issues. but i would say i would never use a monitor that size at that distance, my 27" covers my fov just fine and benefit of higher dpi i guess. and 16:9.
