According to statistics, every ten years the number of diseased diabetes increases almost twice. Today, the total number of patients — more than 380 million people all over the world. In the incidence of diabetes is in third place after cancer and diseases of the cardiovascular system. Since the health of diabetics depends on the timely receipt of insulin, scientists are trying to invent innovations every year, which in time reports on the need for injection and thereby facilitating the life of diabetes. One of these recent new products — «Smart» Contact lenses for diabetics.
Google has presented contact lenses, allowing to track the level of sugar in the body. The device contains a glucose sensor and a wireless transmitter, built into lenses, which report insulin injection. They track blood sugar levels for chemical composition of tears. The company does not exclude that in the future a miniature LED indicator will be mounted in the device, which will notify about too high or too low blood glucose levels. At the moment, Google is already tested by lenses prototypes that can provide information about blood glucose levels with a frequency up to once per second. Also, the company is considering the ability to embed a LED to quickly notify the user in situations where the glucose content is approaching critical values.
The sensor built into the lenses and the chip do not interfere with the vision, since they do not affect the pupil and iris. The developers have done the jewelry work to which years left, and became the first to be able to create the most miniature glucometer. At the same time, representatives of the company Google emphasize that they still have a big front of work in this direction, and while technology is not ready for everyday use. The company also reported that they do not plan to deal with this project alone. Corporation intends to find for development «Smart» lenses expert partners. But today, scientists are confident that the invented type of lenses will lead to the emergence of new and more efficient than the existing methods of combating diabetes. After all «Smart» Lenses are more convenient for patients or less invasive than traditional glucose meters that use blood taken from finger.
