DCHAS-L Discussion List Archive

I ran into them in the 1970s and it's interesting to see they're still around.

I agree with other commenters that the Z87.1 mark should have a
suffix letter or letters to denote intended use(s). It will add costs
for manufacturers to design the markings and include them in the
assembly process.

The bottom of the wraparound lens does open a gap, as has been
mentioned. I'd see these as almost being the filtering facepieces of
protective eyewear, easy to wear and popular, but not thoroughly
protective.
