Anecdotal evidence may be indicating the canopy material of the 80's
and earlier simply let this radiation through?

Anecdotal evidence can be the best kind sometimes...it's from the real world!

I remember in 1972 or 1973 Wil Schuemann coming into the office one Monday
looking like a negative raccoon: pale around the eyes with thin pale stripes
from eyeball corners to his ears, and considerably redder everywhere else on
his face. He'd gotten that way soaring his ASW-12 (in MD, but I don't remember
whether in wave) wearing glass sunglasses and the usual goofy hat.

My subsequent under-canopy experience mostly in the intermountain west has
never replicated his. If it happens it must be possible...

I saw that on a guy who tried arc welding using gas welding goggles.
