Each week, we spotlight a cool innovation recommended by some of the industry's top tech writers. This week's pick is a smart contact lens.

"The first true smart contact lens" could bring augmented reality right to the surface of your eye, said Julian Chokkattu at Wired. California-based Mojo Vision has been working for five years on such a prototype, and it's still "a few years away from becoming a real product." But they are now able to demo a lens that lets you "look to the corner of your eye to activate an interface" for what is billed as the "smallest, densest display ever made."
