Is the vision center supposed to be the same for all shots? If I have a long straight in shot then my vision center is under my right eye. If I hold both hands up and make a circle focusing on a far away object then my right eye is dominant. When i hold up my right hand only and make a circle my left eye is dominant. Is it possible for the dominant eye to shift based on some reference point? I have been toying with the idea of having my left eye over the cue when cutting balls to the right and my right eye over the cue when straight in and cutting balls to the left. Has anyone ever heard of anything like this as far as eye dominance or a shift in vision center?
