I don't have any stats for you but people in our dojo seem to take it in the eye once in a while as well. Just some info on using goggles, there is a guy in our dojo that has perscription sports goggles like the basketball players use. The only problem he has is when we do things like Iriminage with new people that tend to grab the whole side of your head unstead of using a pressure point. Other than that, he doesn't have an issue with them on the mat. btw... he's probably much safer wearing them while doing weapons work with me anyway! he-he-he! oh I see, just POINT the kissaki at their eye, don't actually PUT it in their eye! ok, I get it! HA!
Hey! heres a marketing idea, nerf bokkens! someone run with it!
