Ok, so a follow-on question. For those who have very good hand-eye coordination (where you tend not to fumble an object you are trying to catch), do you wear glasses, and if so is the prescription strong enough to introduce a lot of distortion (curvature) along the edges? I noticed that when I switched to contact lenses for a few years, I was surprised that I could actually reliably catch a ball. Back to glasses now, but I can't catch anymore, play pool, bowling, etc.
