Hi, I'm from australia, only 18 years old, last eye exam 6months ago (routine/all okay). I work in a hotel and I'm a very hyper-aware person--- could say hypochondriac aswell. Anyway, when walking down the halls at the hotel the rooms all have small sqaure signs on the wall with their number, I've noticed by just a mm or two, my right eye catches the sign in it's field of vision before my left eye does when i stand in the middle of the hall. I have no medical history of any problem.
