These unique devices help to cope with illness and psychological problems
Once we read about it in science fiction novels, watched the movies, and now breathtaking devices are more and more included in our daily life. Among scientific and technical innovations, technologies stand out for expanding the possibilities of human vision. They are needed not only to realize their own power and improve the abilities of the "crown of nature's creation", but also help to solve previously hopeless problems, to raise medicine to a new level.
VIRTUAL REALITY: GOOGLE GLASS
In fact, this is a mini-computer that attaches to the frame and allows you to take photos, videos, send SMS, and perform other commands. However, Google glasses do more than just make communication easier.

Such a super-fashionable accessory allows a person to change the characteristics, physical properties of the existing world, creating virtual reality familiar to us from science fiction films. In augmented reality, a person can physically interact with an object, experts explain. For example, act as a designer, changing the color and shape of the surrounding objects at your discretion.

Another "magic" glasses make it possible to look at yourself from the side in real time. Those who have tried it assure us that the sensations are incomparable. Experts suggest that such technologies can be used, among other things, to help people with psychological problems. For example, there are known experiments when people “changed” their sex with the help of augmented reality glasses, tried on various roles in order to better understand their own personality.
FOR DIABETICS: "SMART" LENS FOLLOWS GLUCOSE
This is another development of Google corporation, while it is in the experimental stage, but, as expected, in the near future it can become a real salvation for diabetics, whose number is growing around the world. Patients need to regularly monitor their blood counts and have to pierce the skin on their fingers in order to drip onto the test plate of the meter.
A “smart” lens is able to obtain the necessary data from the tear fluid that constantly bathes our eyes. The device uses biosensor technology and has a microscopic sensor capable of transmitting information to a smartphone.
Now scientists are working to equip the lens with a safe LED - then, with critical changes in the patient's glucose level, the eyes will light up. In short, magic in action!
Blepharogel 1 helps relieve dry eye symptoms
TO THIS TOPIC
In a variety of situations where the eyes become inflamed, including when wearing lenses, experts recommend using modern ophthalmic drugs. For example, in the mornings and evenings - Blepharogel 1. It contains Aloe Vera extract and hyaluronic acid, which improves metabolic processes in the eyelids, increases the stability of the tear film and thereby helps to get rid of the dry eye symptom. Such a tool is also irreplaceable for those who have to work at a computer for a long time.
VISUAL PROSTHESIS: "SEE WITH THE BRAIN"
As you know, people often go blind due to the death of retinal cells - this is the shell of the eye, which perceives the image and converts it into nerve impulses. They are transmitted to the brain, decrypted there, and we get the usual visual images of objects - we see them. For those who have lost such an opportunity due to injury or illness, a unique device has been created, the essence of which is as follows.
A person puts on glasses, in which a small television camera is placed, and the optical signal from it goes to an electrochip implanted in the visual cortex of the brain at the back of the head. The chip consists of electrodes, when they are excited, there are flashes of light - phosphenes. You can imagine them if you lightly press on your closed eye.
Thus, the visual picture coming from the TV camera is converted into a certain set of light flashes. At first, they seem chaotic and disorderly to a person, but with training and use in everyday life, the brain begins to recognize and get used to the fact that each object corresponds to one or another model of flashes.
Several dozen operations were performed, they were successful, one of the patients was even able to drive a car. Now scientists continue to research and improve technology so that blind people can get more complete images of the world around them.
FEEL … IMAGE
Another unique device for helping the blind is bionic contact lenses that allow the eyes to “feel” the image of the real world.
This technology, developed in Israel, is based on the principle of so-called sensory replacement. In fact, a person who has put on innovative lenses becomes able to feel the image … the cornea of the eye. A microscopic camera is attached to the frame of the glasses, the resulting image is converted into electrical signals using a special transmitter, and they are sent to the bionic lens. This creates a "tactile" equivalent of the image on the patient's cornea.
Considering that our cornea has 600 times higher tactile sensitivity than fingertips, it allows us to perceive images quite accurately. An important advantage of this technology over the previous method (see "Optical prosthesis: see with the brain") is non-invasiveness, that is, there is no need to implant a chip in the head. So far, the new development is experimental, but its rapid introduction into clinical practice is expected.
IN THE EYES OF INSECTS
American researchers have developed a technology that allows you to enrich human vision with the abilities of a wider view - like in insects.
The device looks like an optical lens, which contains transparent polymer "pockets" filled with liquid, located throughout the lens area. When compressed or expanded, the optical properties change, and due to this, the lens provides a wide angle of view, characteristic of the eyes of insects. Experts believe that this experimental development could be useful, in particular, in laparoscopic surgery. Physicians will receive a wide viewing angle while maintaining the ability to accurately assess the distance between the lens and body tissue. This will significantly improve the accuracy of operations.
