Wow! Thanks, friend! I think this is the probable reason why my fully corrected glasses and the sales people with perfect eyesight had problems. One sales fellow had lasik which left him 50 degrees off (cannot remember exactly off by plus or minus) who did not have any problems focusing.
Now, does this mean I will need a + 0.5 diopter if I want to focus with fully corrected glasses?
BTW is 0.5 diopters the equivalent to 50 degrees for glasses?
