This thing called vision center

Of course, I have my own view points on this.

First, let’s really define it with real world concepts. From my basic knowledge of vision, my definition of vision center is that point where both of the eyes line of sight is converged on.

Notice it is where the eyes are directed to and not which way the head is directed.

You can change the eyes line of sight convergence point, vision center, just by moving your eyes and never move your head.

Using a bridge negates the idea that the head therefore the vision center needs to be over the cue, or also shooting one handed.

The are lean over shots also. You lean over to get the cue in position but you can not do so with your head.

Just a few thoughts.

I do use my vision center/line of sight when using the mechanical bridge or shooting one-handed, what would be the reason to avoid doing so?

We can swivel our eyes to view a target, but it's still best IMO to keep the vision center/line of sight consistent including the neck rotation--that is, to look "straight ahead".

Exactly. By turning your head, to the right for example, and then focusing on an object to your left, you can have both eyes very close to capturing the same 2D perspective, which affects the brain's ability to accurately perceive a depth/3rd dimension.
 
In my dotage my vision has gotten worse.

And in short order I anticipate having cataract surgery. But in the meantime I am finding some success with turning my head a bit right to align my cue more under my left eye. Its never been something I found useful before but it does seem to help with creating a better shot picture for me now.

We turn our head & eyes very many times each & every day. For the most part we keep our eyes level. Try "tilting" you head to one side or the other & keep up it that way with the eyes on a 'diagonal' & spend the whole day like that.

NASA did an experiment where I get placed goggles on subjects that then what they saw up side down. Over time the brain turn the image back to up side up. When the goggles where removed the subjects saw up side down & again over time the picture was reversed. The image on our retina IS up side down just that through a camera lens on the film. It is our brain that reserves our... 'Perception of it so that we can function properly. Just as we all do not have the same spacial awareness we also do not have what could be called objective vision.

I would think that Gene Albreight may know more about the eyes "for pool" than maybe anyone else. He showed me over the phone that I am not consistently right eye 'dominant'. Now that is not the hard wiring to which Fran Criminal refers.

We do many naturally, but sometimes naturally is not the best for a given task even though we would think so.

No, but that doesn't mean the hard wiring she refers to doesn't exist.
