2010-01-29 - Dominant eye


This is something I was vaguely aware of. You obviously use both of your eyes to look at things- but you use one more than the other. You probably do it without thinking most of the time. You'll naturally use your dominant eye when looking through a camera lens or something similar. This is how you test to see which is your dominant eye:

Extend both of your arms out in front of your chest with your palms facing away from your body. Stick your thumbs out and overlap your hands by crossing your thumbs and finger tips, leaving a hole in the middle. It should look something like this guy.
Look through the hole and focus on a small object about 20 feet away.
Close one eye, and then the other. When you close your dominant eye the item will jump out of your field of vision (behind your hand). When you close your weak eye the item will be in relatively the same position it was with both of your eyes open.
Your dominant eye has no correlation to your dominant hand. I am right-handed and left-eye dominant. This isn't incredibly useful unless you're doing some corrective treatment with your eyes or you're learning to shoot a gun.
