I think part of the issue is that Zuckerberg is a smaller dude and they're pretty big sunglasses so he has a bit of that "Look! I'm wearing dad's glasses!" thing going on.
So that's half of men and most women ruled out?
Big glasses are actually quite popular with women.
Heavy frames and large lenses tend to compensate for larger noses, and other facial issues (although they won't come out and say that). Clear glasses can really focus on the eyes.
I know a couple of women that have made large, heavy-rimmed glasses into a real fashion statement.
