Can anyone tell me in a general sense how easy it is to detect this problem in a day to day usage? Because I can't tell if I have the problem or if my brain/eyes are playing a trick on me attempting to convince me that I have the problem. If I have the problem it's hardly noticeable. If I don't, then my eyes are doing as I described above. The pictures posted in the various posts aren't enough for me to determine if I have the problem.
