Hello All,
The glasses pictured are Gentex Ballistic laser protective glasses. (Minus the hard case.) My experience with them is-
The Green lenses are Mil-Spec Red-IR lenses.
The Brown lenses provide protection from IR and all visible spectrum, but are really dark...
the grey lenses while not certified for laser protection at all, are great for 405nm. (They attenuate everything, you can only see flourescence...)
But don't buy them from this site. $20 is a rip-off. I regularly get them for $10. I'll post a few links when I get the chance. ($10 beats $100 for laser goggles any day... ;-)
cheers,

p.s.- WackBag- they are way better than OD2 for their rated wavelengths. (More like OD 3 or 4. I'll post the mil-spec if I can find it...)
