safety glasses??why??

We were doing some milling with a bad rotary table, and the endmill shattered.... Sending very hot pieces of Carbide into my glasses, arms, and chest. Come by 114's pit some regional and I'll show you the scars.

Had I not been wearing my glasses, I probably would've lost my eyesight.

(as a second note, NEVER use a rotary table unless you know it's in perfect condition... it was scary to have that endmill fly apart.)

Although I have never personally had anything fly at me or seen anything flying at somebody (other than poof balls) in FIRST, I still wear my safety goggles.
I recently bought a $6 pair of safety goggles which fit over my glasses at a local hardware store, I can see perfectly out of them, and they don't fog up.

I see no reason not to wear a pair of safety goggles. If the only ones you have access to are scratched up and dirty, then get your own.
