If this is not just a sarcastic note, no one with any sense shoots withour safety glasses these days. In my Rifle & Pistol club, no one goes on the range without glasses. An autoloading rifle or handgun can pop a hot brass case right back toward your eye. You start training your youth shooter to put the glasses on before loading the gun.
It’s a joke referring to the movie “A Christmas Story.” The little boy wants a BB gun for Christmas but everyone keeps telling him “You’ll shoot your eye out, kid.”

I just replaced my shooting glasses. A month back, a pellet fragment bounced back 10 meters and embedded dead center in the lens. I got tired of looking at the scratch it left, so I bought new ones - and never shoot without them.
