On the face of it (pun intended), these look like sunglasses with a couple of cameras fitted. There doesn't seem to be any AR functionality, which means these are designed to capture photo and video and pipe it to Facebook.
The only controls visible seem to be a button on the right-hand arm. There are also tiny holes in the frame for what are probably speakers and a microphone.
Because these sunglasses need a battery and other associated electronics, the frames look a bit on the jumbo side.
There are no signs of a charging port, so one would assume wireless charging.
