A comment on Blackjack's Text Test. If you read text, you won't be able to tell which eye is seeing what, but if you close your non-dominant eye, you will see the text shift, that is because that eye was not really focusing on the text. Non-dominant eye is used for demension.

Wrong. Non dominant eye/dominant eye would not factor into this either. (What you are speaking of is depth perception, not dimension, and that is also achieved with both eyes, not one independaent eye) I would challenge anyone to provide any proof of the contrary. Dominant eye will only be a factor with one eye shut, and it doesn't matter if you're ambidextrous. With both eyes open, dominant eye and non dominant eye work together and send the signal to form ONE VIEW, not two. If you are seeing two separate images, you are:
A) Experiencing positional horizontal nystagmus
B) Inebriated, which causes involunatry nystagmus
C) Cross eyed
So unless you just got off a rollercoaster, or you're drunk, or you are cross eyed, pretty much you fall into the other category, which is that normally when your eyes are open (both of them) you see ONE Image. Admittedly in my obnoxious test, we are looking at a screen, and it is one dimensional. Doesn't change the fact that if you were to place an object (like a steno pad) on the bridge of your nose to act as a wll between the left and the right eyes, you would still be able to read this text normally, as if it was not there. Close one eye, and it is a different story.
You mention that the non-dominant eye is used for dimension. That is incorrect. Both eyes must work in unison to create depth perception (not dimension), and normally the dominant eye will serve that purpose, not the non dominant eye. Also, with the binding of the steno pad used as a wall between both eyes, close either eye, and the text moves. Open both eyes, and tell me which eye is seeing the center of the text. Answer: Trick question. Both eyes do. This is the problem with dominant eye theories in relation to shooting pool, a task normally performed with the assistance of both eyes, not one. When assited with the other eye, they compensate for each other and DO NOT WORK INDEPENDENTLY FROM EACH OTHER. Newsflash. . . you cannot help this either, and it is ridiculous to say otherwise.
Laura says she is ambidextrous, and she can toss away the mechanical bridge. Great. That still won't change what she sees out of either eye, nor will it change the fact that she'll have to learn the game all over again shooting with the opposite hand. Fran Crimi says dominant eye has a lot to do with head alignment. I agree head alignment is important, while at the same time I contend that it is all about alignment, and nothing to do with eye dominance. Eye dominance and head alignment (with both eyes open) have nothing to do with each other anyway. I am a strong believer in equilibrium, when the ears are centered with the shoulders (head not drooping forward) amazing things happen in shotmaking (due to stability, mechanics, and balance - not eye dominance).
Then we have the folks that say that my test proves nothing. My answer is, that the dominant eye "theory" is your "theory" and not a fact. When eye dominance becomes a factor in shooting pool, and the theory is proved, come back to the table and discuss it. It is a fact that when both eyes are open, they work in unison, transmitting signals to the brain that are interpreted into one image. Which eye is dominant and non dominant does not matter as what each eye is viewing is blended to fit one image. If your eyes do not do this, then I hope you do not drive, and if you do, I'm staying away from you.
