So, I went and did some looking around at how this thing supposedly works, and it's pretty cool and certainly doable. The outer ring holds power and processing components, while the tiny tip on the stalk carries a microled display. The display isn't particularly high resolution, but it's plenty good enough to project even photographic images onto your retina (not at photo quality, of course). So, you'd have basically a clear view past all the stuff in the contact. The image would appear as if it were out in your field of vision at the same distance as the subject you are observing. Personally, I think this is like that cell phone I had back in the 80s: Clunky, expensive, and not so powerful. But it demonstrates we can do it with today's technology. I can see this, without involving augmented reality, actually being a real, I-can-buy-it thing in not so many years.
