Went to the site and it looked real good until I saw that they only do
plastic lenses. Leaves me out.

I'm curious--why does it leave you out?


Because if it isn't glass, they are near useless to me. Last pair of
plastic
lenses I had lasted about 6 hours.

Do you work over a forge, grind metal in enclosed spaces, or do you
just weld without a mask?


Machine shop. Grinding is one place where plastic lenses are superior. If
sparks from a grinder hit plastic lenses, it just bounces off. With glass,
when a spark hits the lens, it causes a, for lack of a better word, bump.
This bump is glass and cannot be removed. Guess how I know.
