So apparently the Z87.1-2010 high impact ratings for glasses are the exact same as the standard Z87.1 baseline tests. Meaning your "impact resistant" Z87.1+ glasses are now only TESTED to ~1j of impact.
Before you go freaking out, the minimum lens thickness has not changed from 2003 (2.0mm), so they may very well hold up to 3j impacts, but they're not RATED nor is anyone LIABLE for the lenses breaking over 1j
So first of all, I'd like more than just the 3 people we had double, triple, quintuple check this math and report back to here:

End result is we may have to *very quickly* raise the minimum eye protection requirement for airsoft in Canada to MIL-PRF31013 (7.5j) pretty much overnight.
I REALLY hope someone proves us very wrong on this and the standard is still in the 3j range, but if not, everyone change their shit immediately.
