New Contact Lens Allows Users to Zoom When Blinking

A new contact lens is setting the stage for future advancements in eye care. The lens allows users to zoom simply by blinking. It was created by researchers at the University of California San Diego and is detailed in Advanced Functional Materials.

To work, the lens is attached to the eye via 5 electrodes. It is the placement of these electrodes that allows users to zoom after blinking quickly twice. An electrical charge causes the lens to expand and contract, making the lens more convex. This initiating blink also responds to eye movement; the lens will zoom in the given direction.

Researchers are hopeful this new technology may be used for future prostheses, glasses, and remotely operated robotics.
