Goal contact lenses can "zoom" with flashing

KOMPAS.com – Never watched a sci-fi movie showing that human eyes could do the business zoom in to see the objects in the distance more clearly? This ability could become reality.

A group of researchers at the University of California in San Diego, USA, manufactured contact lenses that allowed the eye to do so zoom with a wink.

When it is moved or blinks, the ball of the human eye produces an electrical signal called electro-oculography. Researchers at the University of California have designed contact lenses that can respond to these signals.

The contact lens in question is made of polymer-based material and can be adjusted focal length or area of ​​vision depending on the intensity of the signal captured by the eye.

When the intensity of the electrical signal of the eyeball movement is very strong, for example when it flashes twice, the contact lenses made from this polymer may then be of more convex shape to produce an effect. zoom in

"The system developed in this study has the potential to be used in eyes, glbades and artificial robots that will be exploited remotely in the future," the research team summarized in its report. KompasTekno of L & # 39; independent, Wednesday (31/07/2019).

For now, even though it has been proven that the concept is applied, contact lenses zoom The University of California always comes in the form of a large experimental machine with electrodes attached to the skin around the eyes of research subjects.

It may take a few years before the components can be reduced to fit into a compact contact lens.
