I one learn t that the polycarbonate that we used in glasses were rated to protect your eyes from projectiles traveling at around 600-700kmph! Naturally I wanted to test this. My boss happened to be a shooter and agreed to take an old lens to the gun range and shoot at it.
The next day he showed me the lens. He had fired a shotgun at it with 00 buckshot at 12ft and the lens had 'caught' all the pellets! I wish I could find a photo of it but I seem to have misplaced it.
Nevertheless if you get shot at while wearing polycarb glasses, your eyes should be safe, maybe not the rest of your head though! lol!

My prescription Oakley A-Wires lasted me over 10 years (I've lost count), upgraded recently to Oakley Splinters purely for fashion reasons, the A-Wires are still good, use them as a backup pair. Oakley have always been expensive (even more so for prescription lenses) but definitely worth it IMO.
