I've always assumed they are protective goggles. German soldiers in the desert often wore protective goggles as sand is a constant nuisance. Belloq would have further need of protective eyewear as an archeologist because he is often sifting through sand.

Interesting. Yes, you can clearly see they're goggles when Belloq walks into the tent to see Marion. I wouldn't have guessed anti-gas, though. Anti-sand perhaps, but not anti-gas. Good find.
