Eyesight is one of the most cherished human senses -- it's also one of the hardest to repair. That's why most inventions in the retinal implant field deal with restoring people's ability to see. But what if you could enhance your vision like a robot?

That's exactly what has been developed: a contact overlaid with computer circuitry to give people bionic eyesight. This could provide you with a "heads-up" display to be used for piloting or even video games. It is actually powered by radio frequencies, but they've still got to test it out on a real person.

You may be asking yourself if the contact is flexible enough to fit comfortably in an eye. By using a technique that assembles itself with scaled-down components, it's much like normal contacts! This would be the coolest eye accessory to come along ever -- I'm going to be holding out for this to hit the consumer market in the future.
