Eye dominance
I recently started back playing pool after a very long hiatus. For the first month I was playing I would run a couple balls then miss seemingly easy shots. I read about eye dominance her on AZ and just for kicks I did the little test to determine my dominant eye. According to the test, I am left eye dominant and i shoot right handed for the most part. I am ambidextrous, so I can shoot with either hand, but I have always shot right handed and its just what I am more comfortable with.
Here, at home on the dining table, I took a few balls I had from when I owned a table and lined up mock shots. My normal pre -shot routine was to find my line, bend into the shot, and shoot. Most of the time this would line the cue up under my right eye ( I got my wife to help see what eye I automatically went to when bending into the shot.
I thought about it for a bit and decided to try something. I did my normal pre-shot routine, HOWEVER, I did it just to the right of the shot line. When I got into my stance from just a few inches to the right of the shot line, it lined the cue under my left eye (again, the wife helped with this).
She noticed that with my normal stance, my cue would be about 1/2 inch off of the shot line but in my mind and vision, I THOUGHT I was on the line.
I did another test. I took an extra shaft and laid it on the table. I got down in my stance normally and pretended the extra shaft was the shot line. Sure enough, my cue was coming in over the other shaft at an angle, even though I thought I was dead straight. I came into the shot a little to the right of the shot line( shaft on the table) and it lined up perfect.
The next day I paid close attention and lined up from the right while shooting pool. My game instantly improved and I was running 5-6 balls again, ran a couple racks out even.
Ever since then, my game has improved 50%. Its tough retraining yourself how to line upshots when you've been doing it one way for 30 years, but I am doing it.
Eye dominance, at least in my situation, means an awful lot.
