Scientists create lenses that increase the image on command

Scientists at the University of California, San Diego are working on a prototype contact lens that

controlled by eye movements.

How it works

The biomimetic lens consists of elasticpolymer films that respond to electrical signals generated by the eyes when they make any movements. Owners of these lenses will be able to zoom in or out by simply blinking twice.

But it's too early to throw away your reading glasses.So far, the prototype only functions with a special installation of electrodes around the eyes. Scientists hope that in the future their invention will be used in prosthetics, glasses and remote-controlled robotic technology.
