Further firestain inquires

Hi Elliot,

ok, thank you!

I think I will continue to use my Solaris 3.0 IR green lenses…just in case…as I would like to prevent cataracts if at all possible…

I initially got them because they were recommended for my kiln enameling set…and I had seen some posts on cataracts…

I thought that James Binnions thread reply, from back in the day, (copy/pasted below) was helpful too…i think it is the IR infra red that I was trying to protect against…possible cause for cataracts…(?)

(James Binnion thread reply:)

American Welding Society and OSHA both require shade 3-5 for brazing
(our soldering) there is no differentiation for fuel type as they
all emit light that can damage your eyes when brazing.

Three sources for eye strain/damage from light radiated by torches,
the work and the brazing surface.

Infra Red, ie heat probably the biggest danger in brazing cooks the
eye.

Visible light, more a cause of eye strain than damage at lower
levels but can damage if bright enough with long enough exposure
think platinum soldering.

UV, not a big amount of UV from brazing operations and most plastic
lenses (safety glasses) are pretty good at stopping it.

Aur92 and Didymium lenses are glass lenses that are visible light
filters, they don’t much of anything about UV or Infra Red. They are
specifically designed to knock down the yellow sodium flare in hot
glass working and do a good job on the yellow flare from flux and
fire bricks.

If you solder all day every day you need to wear some form of shaded
lens (not didymium or Aur92) to knock down the infra red.If you are
soldering platinum then you need to where at least a shade 5.
