The sunglasses caused quite a stir when they launched last September. They were cheaper and more approachable than Google's high-end Glass wearable, and displayed a clear ring of lights when the user was recording. The camera's footage was unique too, shooting in a circular format that allowed fellow Snapchat users to watch in landscape, vertical, or a mix between the two. Snapchat followed up with a store in New York City, which attracted long lines at first. Recently, however, it's been a lot easier to just walk up and buy a pair (the cold weather has probably helped.)

Ever since Snapchat rebranded as Snap, it's talked about itself as a camera company. The app, it seems, is just the start of a broader push that involves both hardware and software. Wider availability for Spectacles, at least in the US, should also help the company as it gears up for a long-awaited IPO.
