Researchers from the College of California, San Diego, have created a new robotic smooth get in touch with lens that lets you zoom by blinking two times. The lens can be managed by your eye actions. 

Eye actions like blinking carry change potential to sign. Shengqiang Cai, the guide researcher, explained to the New Scientist that the eye has an electro-oculographic likely, even if you are sleeping:

Even if your eye can’t see nearly anything, lots of men and women can however move their eyeball and create this electro-oculographic signal. 

So, these scientists measured the electrical impulse and discovered a way to use it to change the focal size of the lens. The review promises that since of the gentle supplies applied in the lens, relative variations in the focal duration can be as substantial as 32 per cent. The focal length is altered by deforming the lens. In the experiment, the workforce used dielectric elastomer to realize the demanded deformation.
