This seems far-fetched to me.

Mojo (https://spectrum.ieee.org/ar-in-a-contact-lens-its-the-real-...) claims to be on track for this, but:

- their "working demo" is apparently not actually wearable

- it has no built-in battery -- if I have to wear an inductive charger around my eye, I may as well wear smart glasses, right?

- the whole thing has a bit of a Theranos feel about it

I'm skeptical.
