So incase anyone in the future is every curious...
I've been playing with the cue under my right eye now for about 3 days, and I can say that aiming and lining up on shots has become much easier. Almost effortless. Where I am aiming is where the ball is hitting.
The way I went about this was very simple. I looked at the division line on the pool table where the rail cloth meets the wood. I stood behind this line, standing by the short rail... looking at the opposite short rail. I moved my head around so that division line appeared straight. Then I brought my head down towards that line, all the while keeping it straight. Then noticed that it was directly under my right eye.
This may be different for some people, but I think it is a good way to find vision center.
