We had already built a contact lens can act as display screen, but this is the first time a prototype powered by radio waves actually worked on the cornea of a rabbit. This display is currently low ... a pixel.
Will we see a day of real-time information displayed in our field of vision to the way the T-800 Terminator? Most likely if we believe a recent publication of an article showing the latest progress made by researchers around Babak Parviz, who had already begun to build a contact lens for virtual environments in 2008.
At the time, the device could not work done on the cornea of rabbits that had served as a test because no source of energy not supplied. It was, in fact, to study their tolerance to contact lens polyethylene terephthalate (PET plastic bottles) on which an electric circuit, with several LED display was mounted
Today, researchers have succeeded, as they were planning to develop a contact lens similar but powered by radio waves picked up by a satellite circling the lens on its edges.

There is currently only one pixel consists of a blue LED combined with Fresnel microlenses. Indeed, without these devices, the focal length of the eye being what it is, a display made up of pixels would be perceived as mere blur by the wearer of the lens.

If tests with rabbits were again positive, the plastic of the contact lens does not allow the eye to breathe, which is necessary to prevent damage to the cornea in the long run. It also remains to build a screen with a large number of pixels and to test in humans.
By the time Honda presents the latest progress of IBM and its chip Asimo synaptic, one wonders if the world of Terminator technology is not at hand. What is certain is that these lenses could have many applications, not just military.
In addition to project directly the path to a pedestrian in a lost city, they could directly prevent a patient from an anomaly in the composition of his blood or malfunction of an organ from biosensors embedded in his body .
