Hey buds, A Friend of mine has a Windows 8 machine and its a monster---fully loaded, etc. He's being forced to sell it because of "eye and headache problems ?" I don't understand ? ? ? I Googled it and found some Remote answers (i'm sure that Microsoft is in with Google) and couldn't find any concrete answers. MY bud went to a few dr's and they mentioned something about having a Contrast problem and the way his brain perceives contrast. In short, Windows 8 gave him dry eye issues and heaches. (my buds a programmer and very knowledgeable about computers and tried every HW change possible). The end result of having a Windows 8 machine for my friend is that he gets headaches and dry eyes. SO MUCH SO that he was forced to switch back to a Windows 7 machine. When he did---the headaches disappeared. WTF ? ? Anyone ELSE hear of this issue? Google doesn't have an explanation.
