My Jackson EQC filters IR and UV when off. The flash doesn't hurt my
eyes when I forget to turn the helmet on.

That's interesting. I just never thought to ask. It always worried me,
and has kept me from using an auto-darkening helmet. After cataract
surgery in both eyes and 3,000 laser burns on my retina capillaries to
treat diabetic retinopathy, I try to treat them well. Luckily, I can
still see great. I want to keep it that way.

Do you still have the data cards with the cataract replacement
lenses?

Hmm. 'Probably around here somewhere.

Mine say that they block UV on their own. (Mind you -- you
still could get sunburn on the eyeball surface, but not as bad as
damaging the retina. (or course, the UV blocking may not be part of all
cataract replacement lenses -- I may have been lucky there.)

I'll have to look into it. Thanks for the tip, Don.

BTW, after wearing very expensive progressive-lens glasses for eight
or ten years, after the cataract surgery, and my post-surgery eye
test, my doctor announced "you don't need glasses anymore."

Yippee! Now I just wear readers for the computer and reading.
