Scientists Have Created Contact Lenses With Zoom Function

Scientists at Harbin Institute of Technology and the University of California have created contact lenses that can be controlled with eye movement.

Scientists measured the electric potential of the eye and found a way to use it to change the focal length of the lens. As a result, a contact lens was created, capable of responding to this signal.

During the study, scientists measured electrooculographic signals that usually come from eye movements. In biomimicry lenses made of polymers, a dielectric elastomer is used to achieve the required deformation and increase by 32% when receiving the necessary signals.

In order to change the scale, the user just needs to blink twice. Then the lenses will zoom in by 32%, the process of returning to normal vision occurs in exactly the same way – a person just needs to blink twice.

It is still unknown when the lenses will go on sale and who will be engaged in their production. In addition, the study does not say whether scientists intend to use lenses as a separate product or integrate them into ready-made products to improve the quality of vision.

Scientists believe that in the future this technology can be used for eye prostheses or special glasses, and even remotely control lenses.
