Eye alignment.............

learning from an ophthalmologist as to what a physical dominant eye
What do you do in a case where the ortho person determines that the right eye has better focus over all distances, but after a few minutes of play it is only the left eye that can still see?

In my post I wrote that if there is an eye pathology then adjustments have to be made accordingly.

This is a very interesting forum with a variety of views. And I believe there will be more views discovered.

My question is: While rifles and pistols have monocular sighting systems, why do most instructors believe binocular sighting is best for pool? In target shooting, using one eye is accepted however in aggressive pistol/rifle situations both eyes are used.to increase the field of vision and give depth perception. Pool shooting is more like target shooting.

It would be nice if a person actually trained in sports vision analysis could join the conversation. But, in the absence of such a person....

I think the main use of two eyes at pool is in depth perception, which presumably improves your feeling for the cut and carom angles.

On the other hand, one of the greatest players of all time, Joe Davis, had only one eye that was useful. He shot pretty well on a snooker table.

An interesting experiment would be to use eyepatches on both veteran players and beginners, but a tough one to set up. Most people are used to using two eyes and it would probably be a large hurdle for them to change to one.

Aiming a rifle is done with one eye aligned with the barrel (no depth perception needed). I think aiming in pool would be easier with one eye too, even with the eyes above the cue. But, as you say, we need both eyes for depth perception, so we use both for aiming too. The "vision center" is where you see the cue alignment most accurately (like aiming a rifle) even with both eyes open.

I can consciously choose which eye to sight with, but have never tried it while shooting. Maybe a new technique? Do all the shot planning, PSR and even initial alignment with both eyes and then switch to the dominant eye only for the final stroke(s)...? Geno the Ad Machino teaches using different eyes depending on the cut side, but I don't understand (or buy) that technique.

I dislike the shooting analogy for pool. Shooting rifles requires clear sights and blurred targets. In pool, you aim to see the target clearly, as well as peripheral targets like rails or caroms, so two eyes are used.

Almost no pool player has perfectsmonicular or binocular vision (making vision center under one eye or right between both eyes above the center of the nose). This is also why I dislike the shooting analogy.

In practice, it's pretty subtle, it reminds me of reading about the "ticks" in the system that shall not be named. By sweeping your eyes, or slightly favoring one side I think you can kind of see the edges better. At least it feels like it. YMMV. :)
 
Why? You can focus on both (alternately) with one eye.

In rifle shooting, focusing on the target would leave a blurred sight just below the target in peripheral vision. Shooting pool is different, we typically do not see a blurred ferrule in peripheral vision that seems to touch the object ball's (or the ghost ball's) target.
 
Nothing more informative for the mind, than watching the cue ball contact your object ball.
Shooter receives immediate feedback on play conditions.... adjusts as needed.

Re: the shooting analogy: In shooting, the rifle and the target are in a straight line. It’s a one-dimensional shot to aim and to execute (assuming no lateral correction for wind needed.) So field of view is extremely narrow.

In pool, on anything other than a straight-on shot, there is a second dimension: the pocket; the angle to the pocket needs to be determined. Two eyes are better for that.

It could be argued that once the CB path is determined by whatever aiming system used the shot line can be treated as the one-dimensional line, but it would be difficult and confusing to switch between two eyes for aiming and one eye to execute the shot.

How did you determine this? Will you share the experiment?

I think you need depth perception in order to see where the pocket is in relation to the OB, allowing you to accurately visualize the cut angle.
