Scientists from the University of California, San Diego, have created a new robotic soft contact lens that lets you zoom by blinking twice. The lens can be controlled by your eye movements.

How is this possible? In the simplest of terms, the scientists measured the electrooculographic signals generated when eyes make specific movements (up, down, left, right, blink, double blink) and created a soft biomimetic lens that responds directly to those electric impulses. The lens created was able to change its focal length depending on the signals generated.

Therefore, the lens could literally zoom in the blink of an eye.

Incredibly, the lens works regardless of whether the user can see or not. It's not about the sight, it's about the electricity produced by specific movements.
