See also in the dark? It will soon be possible thanks to Infrared contact lenses. It seems to talk about science fiction, and instead it seems that in the near future we could take advantage of these particular devices. These lenses will not only help solve vision problems; According to the statements of those who work there, they will allow you to see in the dark, and also with closed eyes.
The news comes from Chinawhere a group of researchers is working on the ambitious project. Scholars have developed a prototype capable of converting infrared light into images visible to us human beings. The perfectly transparent devices will not need any source of nutrition. Users will see both it visible spectrumthe common one, that the infrared. In substancewill earn a supervisory.
The sensational discovery was published in the magazine Celland is making a lot of discussion.
But how is all this possible? The infrared are nothing more than electromagnetic radiation with a higher wavelength compared to visible light. Our eyes are unable to perceive them. In fact, consider that the human eye is able to capture radiation between 400 and 700 nanometers (Nm) of wavelength, while the radiation reaches 700 nanometers to a millimeter. Chinese researchers therefore employed nanoparticles Able to absorb infrared light, converting it into a visible wavelength. In this way you can perceive radiation from 800 to 1600 nm. Nanoparticles are composed of flexible polymers inserted in common contact lenses. The tests were done both on mice and on humans, and devices proved to be safe.
Not only that. Apparently these lenses would be able to show even to closed eyes. The lenses, in fact, understand the origin of the red light. “It is absolutely clear: without contact lenses, the individual cannot see anything, but when he wears them, he can clearly see the flicker of the infrared light. We also discovered that when the subject closed his eyes, he was even more able to receive this trembling information, because the nearby infrared light penetrates the eyelid more effectively than visible light, so there was less interference with visible light”said Dr. Tian Xueneuroscientist at the base from the research.
“This material offers numerous potential immediate applications. For example, infrared light could be used to transmit information in the field of safety, medicine, encryption or anti -control”concluded.
