Google Shows Off New Iteration Of Glass Hardware 

Google published two photos of the next version of Glass, its computer device that you can wear like glasses, on Tuesday in a Google+ post. A consumer-friendly Google Glass will be available sometime next year — there’s no official release date yet — and current Glass “Explorers” will be able to swap the old pair for a new set. Explorers can also invite up to three friends to purchase the $1,500 lenses.

So what’s new?

As reported Monday by Techland’s Jared Newman, the second-generation has a mono earbud, rather than a speaker. It also is designed to work with prescription glasses.
