Contact lenses are ever-so-important for people who depend on it solely without worrying about wearing glasses. 


Now scientists at the University of California in San Diego have created lenses that can be controlled by your eye's movement, reports Gizmodo

Responding to the eye's movement through specific (up, down, left & right) signals, the lenses work by understanding these electric impulses and responding accordingly.

The electroculographic signals make sure the biomimetic lens respond without any delay, meaning blinking twice will signal the lens to zoom in.

This simply means your eyes can change its focal length depending on what signals your eyes generate.

These lens work regardless of whether a user can see or not, meaning, it can be a useful tool to develop visual prosthesis, adjustable glasses, and remotely operated robotics in the future.
