As you can see from the internal view, two eyepieces protrude forward, although it's not clear if the shell is transparent or not. If not, then the shell will need some sort of aperture, since CEO Rony Abovitz says that the technology uses "wafer-like" components that manages "the flow of photons" to create a "digital light-field signal" in your eyes. Which sounds exactly like the sort of buzzfeed-filled jargon you use when you don't want to tell people how your device works. Given how much money respected investors, such as Google, Qualcomm, Warner Bros. and Alibaba, have put in to the business, presumably there's something very real behind all the fluff.
