I had a hot piece of brass make it over the top of my glasses and rest on my eyelid. While trying to yank my glasses off with my hearing protection on I managed to dislodge the brass from my eyelid allowing it to drop to a point just under my eye before getting the glasses off and having the offending brass drop calmly to the floor. It's healing nicely but I suspect I will be wearing a billed cap from now on when shooting.
Exactly why most of us shoot with baseball or similar caps. Also why women should not shoot while displaying cleavage.
