Does anyone know how to check for left or right eye dominance when you shoot? I heard some guys talking about it at Boy Scout camp this weekend and thought it was an interesting topic since I have never heard of it before.
Hold your arm straight out in front of you at head level. Stick your thumb straight up. Close your left eye and use your right eye to look past your thumb at something across the room. Without moving your head or thumb, close your right eye and open your left eye. If your thumb "jumps" when you switch to your left eye, you are right eye dominant. If not, switch back to your right eye. If the thumb "jumps" you are left eye dominant.
Most people are right eye dominant.

This seems to be how to do it: [I just checked with my son who trained for the US Olympic rifle team and he said this is how they did it]; To check your eye dominance, with both eyes open, point a finger at an object in the distance. Close first one eye then the other. The one that stays in line with the finger is your dominant eye.
Most people who are right-handed also have a dominant right eye, but not always. Some people are cross-dominant, meaning they are left-handed with a dominant right eye or vice-versa.
