It’s not just a ‘camera’, it is also a ‘net browser.............

Yes, it can be used to record things that you are seeing, just like those “spy camera” glasses that undercover sting tv shows use. It’s more like a smart phone, though, because the eyepiece actually has a display and allows you to input commands through eye movements.
