My speculation is that looking at someone wearing Glass messes with us on a deep-seated, perceptual level. Direct eye contact is a huge part of how humans communicate, and Glass interferes with that.
It's worse than eyeglasses or sunglasses, though, because it's asymmetric and offset, so it seems (to me) to trigger some kind of "deformity" cue.
If it really is violating our evolutionary preferences for symmetric faces and unobstructed eye contact, fashion won't be enough for it to catch on.
