Engineers of the George Washington University have succeeded in using nanoscale fabricating techniques to create a flexible contact lens with a biologically safe electronic circuit and light source. This means the lens can be worn, like a regular lens, on the eye. Furthermore, it's capable of relaying information to the human eye which the eye otherwise wouldn't pass onto the brain.

More and more screens which give us sight on the visual world are being created. It’ll be projected into our lenses how we have to walk, in our ear we’ll hear data about the person we’re speaking to, see things that aren’t really there. And all of that in 3D. We’ll have to wait a while for this technology, but eventually it’ll be the most normal thing in the world.
