Google just signed the deal that could allow its Glass wearable computing device to go mainstream. The company has announced a partnership with Luxottica, the eyewear manufacturer behind a host of brands including Ray-Ban and Oakley, to design and produce an exclusive collection of eyeglass frames that incorporate the technology. To start, the deal will be limited to the US market, and focus on Ray-Ban and Oakley. According to a Luxottica press release, the first collection will "combine high-end technology with avant-garde design offering the best in style, quality, and performance." According to a Google-provided FAQ, design will be a joint effort between Luxottica and Google, while Luxottica will handle manufacturing and distribution. The FAQ doesn't say, however, when the resulting new versions of Google Glass might hit the market. It might not be anytime soon, though.
