Scientists create contact lenses that zoom with a blink

The lenses could eventually be used in visual prostheses, adjustable glasses and remotely operated robotics

Spotted: Researchers from the University of California, San Diego, have created contact lenses that can be controlled with eye movements, including a zoom feature that is activated by blinking twice. They work by using the eye’s electrooculographic potential. 

The scientists measured the electrical impulses of the human eye and then adapted them to change the focal length of the lenses, accurately adjusting the focus of the lenses. Changes in the focal length can be as large as 32 percent and are achieved by deforming the lens. 

“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,” the authors wrote in their study.

Springwise has spotted other innovations focused on improving contact lenses, such as smart contacts that can slowly release medication into the wearer’s eyes.
