oxy-propane eye protection?

Yep same shade shield you use for Oxy Acet. Usually shade 5.

I would think that a prudent person would use the goggles for oxy-acetylene, which are pretty dark, darker than sunglasses, but not ridiculously so.

The yellow glow of hot steel does need reasonably dark lenses, perhaps shade 5 as a start, to give a better view of the area on the metal itself.

What are you going to use the torch for? Jewelers use oxy-fuel (generally propane or natural gas) torches and I never met one who used dark glasses except for melting and for platinum work. For brazing, silver and gold soldering, etc. on small items, most feel it's not needed. I don't use shaded lenses except for platinum -- when I'm melting, I just don't stare at the crucible. For platinum, it's essential, though, as the stuff gets white-hot. For larger brazing work, some use shades, some don't. I don't, though I only braze larger stuff infrequently. The oxy-propane flame is nowhere near as bright and radiant as oxy-acetylene, so it mostly depends on how hot the work is getting, and how large the radiant area is. (and how close you are to it, of course).

UV is not a problem with oxyfuel welding. Shade 5 goggles recommended for the visible light.

Thanks everyone!

Yes, it's a jeweller's torch, and will mostly be used for brazing small parts, mostly an inch or two across, in copper, inconel and stainless. I have some small propane torches I use for silver soldering, but they were struggling a bit and I wanted something hotter for brazing.
I got it working on butane (don't laugh, I filled two party balloons, one with butane lighter fuel and one with oxygen, to try it out) - works great. I am seriously pleased. Working with a flame that's comfortably hot enough is so much easier! It's lot quieter than the propane torches too, a calm gentle hiss rather than a whiny roar.
Might try MAPP gas for a bit of welding too. Maybe some ordinary shades for that? I have a nice dark wraparound plastic prescription pair somewhere, but it hasn't been that sunny recently in the UK and they will take a bit of finding ...
One other question you may be able to help with - could I use it for cutting? It's a Minox torch and says "2" on the copper part of the nozzle. Would a cutting nozzle be available? Obviously I'd need lenses for that.

Although shade 5 lenses are recommended, I found those bulky, dark, plastic sunglasses that cover your ordinary glasses work well for me. They are considerably cheaper than the shade 5 goggles from the welding supply people. YMMV.
