Google on Monday said it is joining forces with the frame giant behind Ray-Ban and other brands to create and sell Glass Internet-linked eyewear in the US. The California-based technology titan billed the partnership with Luxottica as its biggest step yet into the emerging smart eyewear market. Luxottica brands include Oakley, Alain Mikli, Ray-Ban, and Vogue-Eyewear. The announcement in a Google blog post came as the web titan sought to burnish the Glass image ahead of its expected debut in the US market this year.
