Hi Marilyn (and everyone else),
Regarding the dark glasses: I've asked a lot of questions and
gotten a lot of conflicting on the subject. Textbook
answer seems to say if you're using any fuel gas/O2 combination,
you need to wear UV protection for your eyes. Many practicing
jewelers I've seen don't bother. A practical person I spoke with
said that the size flame jewelers use wouldn't generate enough UV
to be worried about.
Nevertheless, a blind jeweler does nobody any good. I was
worried. I really had a hard time seeing those little snippets
of solder with the dark UV glasses I got at the welder's supply
shop where I get my tanks filled. Forget annealing based on the
color of the metal being dull red!
Then I was speaking with an optometrist who said the UV
protection is merely a coating on the lens, and can be applied to
any lens, shaded or otherwise! For my birthday (or Father's Day)
last year my sweetheart bought me a pair of Gargoyles(tm)
untinted glasses with UV protection. I think they're actually for
some sort of sport (maybe shooting?), and they've been great!
Much broader field of vision than conventional safety glasses and
undistorted due to the manufacturing technique.
Just thought I'd toss that out! I'd be interested if anyone on
Orchid has anything related to add!
