I'm left eye dominant and this hinders my rifle shooting but has little to do with pool or hand gun shooting. We use two eyes to aim. There is no one finite path for your aim (as with aiming a rifle). Your brain makes a mental adjustment for two eye paths. You should take about 2 seconds longer to focus on the object ball with "quiet eyes." This gives your brain enough time to calculate. Remember to trust your instincts. Don't stare too long. Two seconds is all you need.
Dr Dave is where I first saw this. There is a female psychologist that has developed the idea of quiet eyes. For me, I've seen improvement in my game by focusing on this and principles learned from the inner game of tennis. These two schools of thought are complimentary.
