Scientists Create Contact Lenses That Zoom When You Blink Twice

Scientists at the University of California San Diego have created a contact lens, controlled by eye movements, that can zoom in if you blink twice. “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,” reports CNET. “The lens created was able to change its focal length depending on the signals generated.” From the report: 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. The researchers believe this innovation could be used in “visual prostheses, adjustable glasses, and remotely operated robotics in the future.”
