Created contact lenses with the zoom function. How do they work? Source:

Robotic contact lenses in the future will be available for daily use

Perhaps this news will please all who wear — a team of researchers from the University of California in San Diego () has created a pair of soft contact lenses that can zoom in and zoom out the image, tracking movement of the eyes. In order to see any object closer, enough to blink twice in a short period of time. However, not all so simple: this technology needs to be improved, so today the zoom function can only be used with special equipment that is worn on the head. The paper was published in the journal .

Robotic lenses that can zoom in and zoom out the image, perhaps the dream of every person with myopia or hyperopia. On the one hand, such — a real boon if you need to recognize the number of the approaching bus, or see a street sign. But if you are driving a vehicle and randomly will blink two times, it can create a dangerous situation on the road.

In a flash

To create a “smart” soft contact lenses, the researchers measured the signals, which are generated when certain eye movements, for example when you look left or right. Soft contact lens reacts to electrical impulses during the movement of the eyes. This means that the contact lens “knows” that you are looking left or right, and can function based on this particular movement. However, despite the fact that it is unlikely to be finalized in the near future, the development of scientists opens doors to new opportunities and development of advanced technologies. Researchers believe that in the future the developed system can be used for regulated points of robotics that can be controlled remotely, as well as for medical purposes.

As they say in their paper, the researchers, lens soft contact lenses uses a brand new interface, controlled by eye movements and the resulting electrooculographic signal. Even when the eyes are at rest, between the cornea and the Bruch's membrane — the most internal layer of the choroid of the eye — there is a constant electrical impulse. This momentum can be measured with each eye movement. These dimensions affect lenses.

what is zoom lens?

The lens are made of saline, which is enclosed in two electroactive polymer film and is controlled by five electrodes placed around the eyes. Under the influence of electric current lenses its structure, allowing the user to zoom in and zoom out , just blinking. And because the lenses are made of polymer films consisting of several layers, the relative change in focal length can reach 32%, which makes the zoom function is quite impressive.

working on smart lenses scientists around the world.

Today, the prototype of smart contact lenses requires additional equipment, and the user's head must be affixed. However, there are no buttons to control the development is not provided. Moreover, today lenses can be vulnerable to errors in the recognition of eye movements. However, “smart” contact lenses were not as a commercial product, and is intended to show that the existence of such technologies in the future and may be available for use in real life.
