Single-pixel contact lens tested on a person

Not so long ago there was a news about the creation of a contact lens with a built-in LED display, while the resolution is 1 pixel. The prototype was tested on rabbits. American Ben Krasnov (Ben Krasnow) did not wait for the human trials to begin, and assembled his own lens with an LED. And not just collected, and experienced for themselves. Honestly, the result looks scary: something done “on the knee”, from wire and scotch - and a living person in the eye. In short, a real cyberpunk!

The device consists of a wire coil and an SMD LED (size 0402), which are fused between two ordinary soft contact lenses. The power is carried out in an inductive way from the second coil, which is located in front of the eye in the manner of a monocle. A simplest pulse generator on an electromagnetic relay was used as a signal source.

The display contains no additional focusing elements, so the LED should be visible only as a blur in the field of view. So, Ben will be able to make indicators with a resolution of more than one pixel not before he masters the manufacture of Fresnel lenses of suitable size.

According to the inventor, the lens does not cause much discomfort when wearing, but because of its weight it constantly slides down. For the video demonstration, the LED was fixed with the radiating side out, so that instead of the display we got the “Terminator eye”.
