Always loved that graphic. 
Yeah, ātransmittanceā values are pretty useless - they tell you more about how much you can see wearing them (how good of āsunglassesā they are) than anything about the laser safety.
OD 1.19 isā¦nothing. Most glasses you see targeted at actually helping are OD4 or above for the desired wavelengths.
And am I reading your further quote rightā¦their supplier TESTED at the WRONG WAVELENGTH for this laser??
I just ordered a couple pair myself and went serious, from a real optical engineering supply house not risking my peepers on who-knows-where-from Amazon stuff even. Probably overkill, but went with an OD 6+ formula from 200-500nm. (And yes, I have the enclosure too, but I need to add a couple shields along the long bottom edge since it slightly overhangs the deskā¦even if I canāt get hit I have a cat that might be tempted to chase the beam if it were to scatter out some.)
