Help me identify these "glasses"

[Dopplegarp]

Hi all,

These are from the kit of a South African soldier stationed in North Africa. I am guessing that are some sort of glasses meant to help against sand storms and such. Also included are picture of the case it came in. Any comments welcome!

Yes, these are dust goggles. All kinds were used by both sides. Erwin Rommel became famous for wearing a captured British pair over his visor cap.
