Nowadays science is very evolved, and with each passing day many innovations are being built, the living proof is that, and Nasal Bleeding Seats may soon be a thing of the past.
Scientists at the University of California San Diego have created a prototype contact lens controlled by eye movements. Users can make the lens increase or decrease the zoom simply blinking twice. An article detailing the team's findings was published this month in Advanced Functional Materials.
Biomimetic lenses are made of elastic polymer films that respond to electrical signals generated by your eyes when they make a movement, such as blinking. Known as electro-oculographic signals, humans are able to emit electrical impulses when they are sleeping. "Even if your eye can't see anything, many people can still move their eyeballs and generate this electro-ocular signal," said the head researcher. Shengqiang Cai à New Scientist.
É It is important to note here that the prototype only works on special equipment, and the test subjects had a series of electrodes placed around the eyes. Scientists hope that their invention can be used in prostheses, adjustable glasses and remotely operated robotics in the future.
