My problem is that I am right handed, left eye dominant, but the vision in my right eye is better than my left.
I tilt my head a tad to focus my left eye on the pistol sights. Since I can't do anything with my left hand, so I shoot rifles, with my non-dominant, but better vision, right eye.
My problem, developing with age is the inability to see the sights with my glasses, and unable to see the target without my glasses. I take off my glasses to shoot rifles so that I can see the sights. So far, I have only winged two neighbors and 3 dogs; I am not sure of the identify of the last thing I heard hollering after a shot, but it sure wasn't happy.
