Engineers from the University of California,located in San Diego, created contact lenses with a double optical approximation. You can control the scaling in them using your eyes. It is enough to blink 2 times - and you look at distant objects.
Twinkling twice in a row is a command forfocal length changes in lenses. To obtain such a result, engineers measured electrooculographic signals that generate eyes, making certain movements.
Next, a biomimetic soft lens was created,trained reaction to movement. It also edits the focal length when it receives a certain signal. Thanks to this, the user begins to see far objects better. As scientists believe, over time, their development can be used in smart glasses, prostheses and robots equipped with a remote control.
