Yeah, it's something I picked up. When someone shoots a gun, they close one eye. I applied the same concept to bowling, and it works wonders

. I don't really know how to describe eye dominance, but if you put your hands in a triangle and center an object inside the triangle, close one eye at a time. Whichever eye the object is shown clearly is your dominant eye. Hope I didn't make that more confusing than it should be. I also heard about aiming further down the lane as well. That also seems to work well for me. I just switch up my routine for whichever works best at the time.
