Many of us are aware of the tools being marketed with a promise to improve 'sports vision'. In this case a hitting sport. No doubt all components of sports vision are required to execute the task successfully in a hitting sport. But the question remains, as how this ability is trained. I would agrue that hitters in baseball train their dynamic vision while hitting the ball itself. So how are these various tools like
www.visualedge.com, beads, strings etc. useful? Comments anyone?
