Was: Propane story
My ophthalmologist told me that I’m developing cataracts, and I’d
certainly like to avoid making them worse. I believe Alma suggested
that infra red causes or aggravates cataracts. I had thought ultra
violet light was the problem. Is it IR only, UV only, or both
I’ve been using Auralens’ Aura-92 glasses while viewing enameling
through a kiln window, and when I used to use an oxy-acetylene
torch. James’ statement regarding didymium lenses caused me to check
the Auralens website:
which confirms his assertion that didymium offers no IR protection.
Regarding their Aura-92 lenses, the spectral transmission charts on
their website show that Aura-92 is a lot better than didymium, and
they claim ‘very good’ UV protection and ‘much improved’ IR
protection, but is it good enough?
Their Aura-99 lenses show vastly better UV and IR filtering, but
they block more visible light as well. Should people who do enameling
or use acetylene torches, and who are concerned about developing
cataracts use Aura-99 lenses? Something else?
Clarification of this might be helpful to a lot of Orchideans.
