Oh, then you should definitely look into eye protection.
Also, if you're hit directly in the eye a lot, you should read up on the signs and symptoms of retinal detachment. It may seem kind of scary and freaky, but if your vigilant about protecting your eyes, treatment for RD is a "minor inconvenience" (and in most cases you can train KM etc again), as opposed to permanent blindness!
