Scientists create contact lenses that magnify in the blink of an eye

Imagine a future where zooming in your camera or binoculars is no longer necessary to spot distant flocks of birds.

Telescopic Contact Lens
This future may be closer than expected, as engineering scientists led by Joe Ford of the University of California, San Diego have created a contact lens that zooms when you blink twice.
The team has created a contact lens that zooms on command, completely controlled by your eye movements.
In short, the team measured the electrooculographic signals produced by our eye movements—up, down, left, right, blink, double blink—and then created a soft biomimetic lens that responded directly to those movements.
Bionic lenses or materials are man-made and, as the name suggests, they mimic natural materials.They follow a natural design layout.
What the scientists ended up with was a lens that could change focus based on a given signal.
It’s no exaggeration to say they’ve now created a lens that zooms in the blink of an eye.Or blink twice in this case.
Perhaps even more incredible, the lens doesn’t change based on the line of sight.In fact, it doesn’t need a line of sight at all to change its focus.
It changes due to the electrical energy produced by the movement.So even if you can’t see, you can blink and the lens can zoom.

Telescopic Contact Lens
Aside from how beautiful it is, the scientists hope that their invention will help in “future visual prosthetics, adjustable glasses and teleoperated robots.”
