Scientists develop contact lenses in order to zoom in. Blink twice to get a close look. Seats with nosebleeds may quickly be a thing of the past. Scientists at the San Diego University of California have developed a prototype contact lens regulated by the motions of the eye.
Scientists develop contact lenses in order to zoom in
By simply blinking twice, wearers can zoom in or out the lenses. A paper released this month in Advanced Functional Materials detailing the results of the team. The biomimetic lens is made of stretchy polymer films that respond when they make a movement, such as blinking, to the electrical signals your eyes generate.
Known as electrooculographic signals, even when sleeping humans are able to emit electrical impulses. “Many people can still move their eyeball and generate this electro-oculographic signal even if your eye can not see anything,” lead scientist Shengqiang Cai said to New Scientist.
But still don’t throw away your reading glasses or binoculars— it’s early days still. Gizmodo revealed that the prototype only works in a unique setup, and a series of electrodes were put around their eyes by test topics. Scientists hope that future use can be made of their creation in prostheses, adjustable glasses, and remotely operated robotics.
