If you mean: "Do I have a dominant eye?" I'm not sure because the standard tests for this give me mixed results. Regardless, my
vision center position is with my cue directly centered between my eyes in the center of the chin.
"Occular dominance" isn't necessarily related to one's best "vision center" position in pool. Repeating what I wrote in a previous post:
For some people (e.g., those with extreme eye dominance), the "vision center" position is with the dominant eye directly over the cue. For many people, the "vision center" position is with the cue centered exactly between the eyes, regardless of which eye might be "dominant" or not. And for some people, the "vision center" position is with the cue somewhere between (but not centered) or outside of the eyes, regardless of which eye might be "dominant" or not.
IMO,
it is best to ignore which eye one might think is dominant or not and just determine your "vision center" position with simple drills. A key fundamental of pool is having your eyes in the right place, and this "right place" is different for each individual. The only way to determine it is with a cue and balls at a table. The standard tests for "ocular dominance" won't necessarily help with this.
