Scientists Unveiled Contact Lens That Zooms By Blinking Twice

Reports revealed that scientists have created a robotic soft contact lens that let you zoom and control it by just blinking twice. The invention was made by scientists from University of California in San Diego.

The report also added that you can control the whole lens by just eye movement. The scientists measured the electrical impulse and found a way to use it to change the focal length of the lens.

“The human eyeball is electric – there is a steady electrical potential between its front and back, even when your eyes are closed or in total darkness. When you move your eyes to look around or blink, the motion of the electrical potential can be measured.” according to lead researcher Shengqiang Cai.

“Even if your eye cannot see anything, many people can still move their eyeball and generate this electro-oculographic signal.” added by the lead researcher.

The study claims that due to the soft materials used in the lens, virtual changes in the focal length can be as large as 32% which can be changed by deforming the lens. The scientists used dielectric elastomer to achieve the essential deformation.

The scientists added that in the future, this lens can be used for visual prostheses, adjustable glasses and remotely operated robotics.

How about using it as a superspy?
