SCIENTISTS CREATE CONTACT LENSES THAT ZOOM WHEN YOU BLINK
TWICE
It is absolutely the stuff of science
fiction: a contact lens that zooms on your command.
But scientists at the University of
California San Diego have gone ahead and made it a reality. They've created a contact lens, controlled by eye movements, that can zoom in if you blink twice.
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.
Why create this? Why the hell not.
The researchers believe this innovation could be used in "visual
prostheses, adjustable glasses, and remotely operated robotics in the
future," but I'm waiting for them to turn up on CSI Miami. Could you
imagine the crimes Ice-T could solve on Law and Order wearing these things?
