Dear Snail Scott,
Radiant heat can scorch the surface of your eyeball, the conjunctiva, in =
just the same way that it can scorch your skin. Place the back of your =
hand in the position your eye would be. If it feels dead cold, maybe you =
would be safe. But as one who has had burns and damage to the =
conjunctiva, and now watches those "floaters" (Not as bad as they used =
to be twenty five years ago thanks to Eyebright), I prefer to give my =
sight all the protection I can. Blindness for some is a tragedy of =
nature. But I would be stupid to put myself in a position where I made =
myself blind. Almost did it once. Never again.
Best regards,
Ivor.

I have a pair of glasses described at time of purchase
as "Crews (brand) Storm (model) 5.0 green tint welding
glasses." I use them and they are quite dark. My
eyes feel very comfortable when looking into the kiln
with them, and yet I know that since the brightness is
filtered out, my eyes feel comfortable even though the
IR could possibly still be coming through and I would
still fel jsut as comfortable. After hearing all the
concerns from this thread, I an e-mail to the Crews
company asking them if what I have does infact filter
IR along with UV. They say that both IR and UV rays
are filtered with the 5.0 tint green lenses that I
have which is reassuring, but I want to know for sure.
The only actual welding helmet I've seen (long ago)
used actual glass (along with some sort of film or
coating to create the tint), my glasses are plastic.
Is plastic capable of filtering the same way glass is?
