I don't feel like that would help the aesthetics much. Mostly what it would do is make it look like you were wearing those Craftsman Illuminator eye lights that they sell in hardware stores.

It's the lensless metal bridge across the face that really makes them stand out. I've found that when I snap the sunglass lens into my Glass, even though I look like I'm wearing a pair of particularly douchey sunglasses, I don't get as many people staring. Worn without the lenses in, I feel like a freak show wherever I go thanks to all the gawkers. I've worn Glass in public a mere handful of times—I never use it at all anymore. The conspicuousness-to-usefulness ratio is just not sufficient for me.

A battery pack maybe. But then you would either have to hide a cable in the bridge (An vital area for frames) or have a gaudy cable around the back of your head.

Or go with the asymmetry and get a pirate patch for the other eye.

that's what is bothering me. could never figure it out from a UX perspective, but that is definitely it.
