Eye dominant

I was talking to a buddy a few days ago. He asked if I was left eye
or right eye dominant. I didn't know. So he gave me a test to do.
Make a diamond by connecting your 2 index fingers together and your 2
thumbs together. Find a small object across the room, and put this
hand frame around it with your arms fully extended. As you stare at
the object bring your hands slowly toward your face.

OK, do it before you continue reading.

You find that your hands naturally gravitate towards one eye. I find
out that I am left eye dominant. Since discovering this I have noticed
that I study and read everything with my left eye. I had always
thought both eyes were always equal...I was wrong.

Also, depending on which eye is dominant will affect your shooting.
