There's almost no UV coming off. Instead it is IR and some sodium flare yellow. There are weldingshades # 1 and # 2 that he might not find too dark.

One of our labs uses sealed borosilicate glass tubes for some experiments. A tech seals several dozen of the tubes with a torch (I know he is using oxygen, I think the fuel is propane, I know it is not acetylene) at onetime. He was complaining about the brightness of the light, so is now wearing safety sunglasses that block 99+% UV.
Anyone have experience with something similar to this? I have seen the didymium glasses that hobbyists use for glass blowing, but I am not surewhat eye protection to provide. He has tried welders goggles, but found them too dark.
Thanks,
