Think about a future wherein no more zooms are needed in cameras or binoculars required to identify that faraway flock of birds.
This future could also be nearer than anticipated, as engineering scientists led by Joe Ford from the University of California San Diego in the U.S. have created a contact lens that zooms while you blink twice. The group has created a contact lens that actually zooms upon your command, purely controlled by your eye movements.
Put simply, the team measured the electrooculographic signals created by our eye movements – look up, down, left, right, blink, double blink – after which made a soft biomimetic lens that straight responded directly to those movements.
Biomimetic lenses, or supplies, are man-made and because the name suggests, they mimic pure materials. They observe a natural design layout.
Electrooculography is a way used to monitor and record eye movements.
What the scientists ended up with is a lens that is in a position to shift its focal length relying on the signals given. Quite actually, they’ve now created a lens that zooms at the blink of an eye. Or two blinks in this case. Maybe much more incredibly, the lens does not change based on sight. The truth is, it would not want the sight to change its focus in any respect.
It changes due to the electricity generated by the movement. So, even if you cannot see, however, can blink, the lens can zoom.
However, actually seeing the change in focus is what makes this invention all the more fascinating.
