This Contact Lens Zooms In When You Blink Twice

Scientists have developed a contact lens that can be controlled by eye movements.

For example, it can zoom in when the wearer blinks twice, the Independent reports.

The lens responds to electrical signals generated by the eye. It’s being developed at the University of California at San Diego.

“Even if your eye cannot see anything, many people can still move their eyeball and generate this electro-oculographic signal,” said Shengqiang Cai, lead researcher, according to New Scientist.

The lens can change its focal length in response to up, down, left, right, blink and double blink movements of the eye.

The researchers believe the soft biomimetic lens could be a step toward “visual prostheses, adjustable glasses, and remotely operated robotics in the future,” CNet notes.
