Actually, I believe that with the many iterations of the space armor, there wasn't really any sort of eyes lits to speak of except for decorative ones for esthetic purposes. His space armors all had internal screens or holographic HUDs.

Stark also isn't the type of inventive genius to create a design flaw wherein he'd only be able to operate his armor through visual outputs only and through cameras located in the helmet. (Unless it's a convenient plot device to build drama I guess, artistic license being what it is) Anyway, the point is, there is obviously some time of work around that a writer will plug into the story in the event something like that happens. I wouldn't be surprised if there is (or will be a story) where he's in space and takes off the faceplate on his armor to reveal a standard space mask or something underneath the armor so he could take it off in space as need be.
