You might not know it, but one of your eyes completely determines the direction in which you look. That’s the eye that you need to use to aim your firearm.
To determine which of your eyes is dominant, do this:
- Extend your hands in front of your face, placing them together so that only a small opening remains between them.
- Look through that space with both eyes open, focusing on a distant object.
- While maintaining your focus, keep both eyes open and start moving your hands closer to your face, continuing until your hands reach your face.
- At this point, you will have instinctively lined up the opening in your hands with one eye — your dominant eye.
