I agree completely with Ben and Conor about releasing these rules early. For one thing, the change to using the ANSI Z87 standard is incredibly important. I've seen countless people wearing standard eye glasses with those flimsy side-shields. Those don't work. No, no. They REALLY don't because your glasses aren't safety glasses to begin with.
I am posing a challenge to everyone who uses power tools: Take a pair of real safety glasses (they have "Z87" or "Z87+" imprinted in small letters near the edge of the lens). Remove the lens from the frame (it should snap apart - you don't have to break it). Now take a drill with a phillips bit and put a deck screw into the lens. Awesome, huh? It DOESN'T crack. Now take the same lens and hold it steady on a flat surface. Take your favorite hammer and hammer the lens (not the screw). Really hammer it. It doesn't shatter, it only scratches it!
Now are you convinced? If not, it's your sight that's at risk.
P.S. Please don't use that pair of safety glasses again
But you should keep them around to demonstrate to those who complain about this requirement.
