You never had the idea that it would be nice have eyes with a zoom function, like in a camcorder or camera? Undoubtedly, nature has awarded us a certain quality focusing on short and long distances, but we don’t able to visually bring closer what is far from us and therefore too shallow.
And only in science fiction films show this feature man, but we somehow understand that these are all fairy tales – and nothing more. But it was not for nothing that in one Soviet song it was sung that we were born for in order to make a fairy tale come true. And really, remember how many fantastic ideas came to life in recent decades. And this process is accelerating. It looks like eyes with zoom functions become reality.
At least that’s what California researchers say. University that is located in the city of San Diego, which together with Chinese scientists have created unique robotic contact lenses, capable of such a miracle (Advanced magazine wrote about this the other day Functional Materials).
This technology is based on the function of electrooculographic signals “that are generated by the movement of the eyeball even in in the case when a person seems to see nothing. Thereby the zoom can work due to the muscle current of the eyeball, and the scale itself Visions are regulated by the blinking of the eyelids.
A new type of contact lens developed by American scientists and their Chinese counterparts, just allows you to use such unique, almost fantastic feature. As the presenter says the specialist in this study, Shengqiang Cai, their technology can be used as in visual prostheses or special adjustable glasses and robotics.
Robotic bionic eyes are definitely new. word in medicine and robotics. Let’s hope this breakthrough US and Celestial scientists will not remain at the laboratory level research and will not be put in a long box as “unpromising” direction in the study of the human eye.
However, this is unlikely to happen: note that the researchers University of California tackle this problem already some years. For the first time they announced their achievements (then very modest) in 2013. And then the military became interested in it USA…
