Contact Lens

Scientists created a contact lens that zooms in and out just by blinking your eye.

University of California San Diego scientists designed a robotic contact lens that can respond directly to user’s eye movements.



The case of the lens is made out of polymers that becomes more convex or concave, depending on the voltage change, allowing it to “zoom in or out.”

“The system developed in the current study has the potential to be used in visual prostheses, adjustable glasses, and remotely operated robotics in the future,” advanced functional materials.

“In the current work, a novel human–machine interface is developed to use electrooculographic signals generated by eye movements to control the motions and the change of focal length of a biomimetic soft lens.
The motion and deformation of the soft lens are achieved by the actuation of different areas of dielectric elastomer films, mimicking the working mechanisms of the eyes of human and most mammals. The system developed in the current study has the potential to be used in visual prostheses, adjustable glasses, and remotely operated robotics in the future.”
