Just to state my position, no i do not think visors should be mandatory. I, personally, think if someone is crazy enough not to wear a helmet, then let them. But that is just me.
Anyways, wasn't it Al McaInnis that had to sit out for a season after a blade got in between his visor? As i remember he never was the same afterwards. Yes, he was getting old and i am sure he had other complicating injuries. But that one was particularly nasty.
Other than Homer, I cannot think of another serious eye injury in the past season. Stitches? Yeah sure, they are hockey players. They know a thing or two about stitches. But, if try and tell me that NHL hockey players are checking into the Optometrist as often as they are checking for the tooth fairy? Then i am going to have to all BS on that.
