Contact lenses that measure blood sugar
Recently, American medicine scientists have given contact lenses a new task to measure blood sugar levels for glasses.
The contact lenses are not only a means to return the accuracy of sight to those who are near, farsighted or change the eye color for girls who like fashion, but also American doctors to give them a task. The new case is to measure blood sugar levels for glasses.

Currently, contact lenses (often called contact lenses) are used to adjust the convergence point for the eyes of people with visual disabilities but also as a mini laboratory as well as a floating screen. without any other extra device.
The glass made it possible because the scientists had paired it with microelectronic components and materials that didn't excite the eye. Since 2008, Dr. Babak Parviz, of the University of Washington, has designed a prism with optical diodes, which he gradually improved and gave him the function of determining blood sugar levels for patients with diabetes. Street.
This technology is very simple. Glucose levels in the body's mucus (eg in secretions from the lacrimal glands) are directly proportional to blood sugar levels. A chip reacts with glucose, including some tiny electrodes, which come in contact with the viscous liquid in the eye, forming an electrical current that passes through. From the extremely small electrolyte measurement of this current, people deduce blood sugar levels. The substrate of the electrode layer is made of polyetilenterephalat.
The information that contact lenses get will be sent to a portable device, looking at the amount of sugar in the patient's blood. Thanks to the optical diodes, glass spectators can see any images that are transmitted, even if you can watch a film directly sent by friends to this amazing prism.
