Truth to that.
The differences between the very top hitters and a level just below them is so small that every advantage helps. Tiger Woods got laser surgery to make his eye better than 20/20 and it improved his game, but he was #1 in the world before his surgery.
I read somewhere that in Olympic sports the gap between gold and 4th place (no medal) is approximately 0.5% for most events. Better vision can turn a player on the national team into one of the best hitters. It won't turn a beer league hitter into Ted Williams.
DD 1 switched from glasses to contacts because it made school and life easier for her. She quit softball less than a year later, and still wears contacts.
