I'm incredibly right side dominant including eye, I have to focus hard on seeing with my right eye -(as I can consciously feel which eye I am seeing from) and picking out dimples on the left side of the ball to help control my potential for a massive over rotation on backswing, I also play a push draw and am working in reducing an overly in to out path.
That said, if I don't control over rotation my head turns off the ball and I completely lose sight of the ball, not helped by a neck fusion at C6/7!
Where I feel I really struggle is putting alignment, lining ball up with the hole from behind with my left eye closed, stand over the ball and it looks completely different, as in miles out when looking with both eyes, not helped by my current S2S Jailbird which looks weirdly closed and a force forward press etc is not suiting my eye at all - time for a change!
