A day after inviting members of its Explorers program to swap their old frames for new ones, Google Glass is showing the world what the latest model looks like. In a post on Google+, the company shows a slightly modified version of Glass that includes a removable mono earbud. These will also be the first models to support prescription lenses, the company said.

Members of the Explorers program will be allowed to invite up to three friends to purchase the $1,500 hardware. The move comes as Google is reportedly ramping up production of Glass, and possibly building a crazy floating showroom for them in the San Francisco Bay. A version of Glass targeted at more mainstream customers is expected to go on sale next year.
