Just as you have a dominant hand, you also have a dominant eye. You need to aim with the dominant—or master—eye for the most accurate shooting. Usually your dominant eye is the same as your dominant hand but not always, and it can change.
To determine your dominant eye:
- Open both eyes, and look at a small object in the distance.
- Form a small triangular opening with your thumbs and forefingers.
- Stretch your arms out in front of you.
- Focus on the small object while looking through the small triangular opening.
- Make the opening just large enough to see the small object, and keep both eyes open.
- Bring your hands slowly to your face, keeping sight of the object through the small opening; the opening will come to your dominant eye naturally. If you are not sure, close one eye at a time. The weak eye will see the back of your hand; the strong one will be focused on the object in the triangle.
