No matter what the situation here is, that's crazy shit.
If that was a real eye, then this guy was cool as a cucumber for having just lost an eye.
If it was a glass eye...then how did he get licensed? First of all, for not being able to see out of one eye (which gets the fight stopped in normal circumstances), but also, even if you can fight with one eye, isn't having a glass eye in your head at the time pretty dangerous? Couldn't that shit get kicked into your brain or something?
