I'm in the process of getting an answer from my source on safety and
industrial hygiene on the question of eye protection for neon.  In going over
the posts so far I am surprised at the concern for UV and not IR which is what
is more prevalent in torch work.  I believe the phosphor excitation that was
mentioned when in proximity to the flame is caused by thermionic emission of
electrons from the torch fume.  I don't think that there is enough temperature
in a gas and air flame to cause UV emission although as I said, I am getting
an expert opinion on that.

 As for myself, I don't wear glasses except when working soda lime or pyrex
when I use the didymium glasses to cut the sodium flare.  For hot glass work
welding glasses of a shade of 6 are the recommended eyewear but it would be
much too dark for neon work.  I think that there is concern for glass
shattering in the eye as well.  I'll continue on this some more (I'm getting
"lets go" glares from the wife).  So......
