Google is expanding the availability of its Internet connected eyewear Google Glass to more people, but not the general public just yet.
Google Inc said yesterday that it is allowing the 10,000 or so people who have been testing out its wearable computer to invite three friends each to buy Glass.
The gadget, which works like a smartphone but is worn on your head like glasses, costs $1,500. The invites will be available in the coming weeks.
Google says it's also letting users who bought their device before Monday to swap out their Glass for a new one. The new devices have been updated to work with prescription frames and include a single earbud.
Glass has a hands-free camera that shoots photos and video through voice commands.
