In case some of you don't know which is your dominate eye, you can do a test. Hold your finger out in front of your eyes, extending your arm as far as it will go, use that finger to cover an object completely with the finger, then making sure you cover the object from view with BOTH eyes open, close one eye, and if the finger stays covering the object with the eye that is open then that is the dominate eye. Yet if the finger moves from view of covering the object, then that is your eye that is not dominate. I guess though some people are left and right brain dominate so I guess this might not work for them.
