Are you right-handed, or left-handed? When using a fork, writing, or throwing a ball etc., predominantly one hand (right or left) will feel comfortable performing these actions. If you always use your right hand, you are "right-handed." If you always use your left hand, you are "left-handed."
The same can be said about the eyes. Just as a person can be right/left handed, everyone has a "dominant eye."

Discover Your Dominant Eye

1. Select an object that is a few feet away from you.
   
2. Stare at the object and then point to the object using your index finger.
   
3. When your eyes are focused on the object and not on your finger, you will see two blurry fingers in your line of sight.
   
4. Now, close one eye and then close the other eye.
   You will notice that with one of your eyes closed, your index finger will point exactly at the object, however, when the other eye is closed, your finger will point at an area slightly shifted to the side of the object. The eye withwhich you see your index finger pointing exactly at the object is your "Dominant Eye."
