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.
