A eyelense that zooms in when you blink: A Technology for Future; Inspired from James Bond.

Looking ahead For those who aren't fans of eyeglasses contact lenses are a grotesque alternative choice But scientists have created a way to make them more splendid allowing users to enlarge objects just by flashing twice.

Scientists at the University of California San Diego create amazing soft contact lenses by measuring electrooculographic signals that are produced when the eye makes action such as up and down left and right and blinks Even when your eyes are closed or you are in total darkness these electrical impulses can still be produced.

"Even if your eye can not see everything a lot of people can still move their eyes and generate this electrooculographic signal " senior researcher Shengqiang Cai told New Scientist."

The lenses made by scientists can change their focal length rely upon the signal produced by the eye They use a dielectric elastomer to change the shape of the soft lens allowing the focal length to shift by 32 percent This allows the lens to enlarge entity just by blinking twice.

The researchers said the invention could have applications in "visual prostheses flexible eyeglasses and remote controlled robotics in the future" It remains to be seen whether it will be used by the armed forces and government organizations but you can speculate the potential of what are substantially mini binoculars built in the eyes of soldiers and spies.
