So in case anyone wants to verify which eye is their dominent eye, here is the easiest way to do it...
1. Extend one arm straight out in front of you and hold up one finger vertically so that you can use it like a rifle sight.
2. Move your finger rifle sight so that it is lined up on the target of choice, make sure you leave both eyes open when you line it up.
3. Now while still line up with both eyes open, close just one of your eyes and then just the other one.
4. With only your dominant eye open, the target will still be lined up with the sight the same as both eyes open, when you close your dominant eye the target will shift shift left or right (in the direction of your dominent eye)...
