New contacts you see bad light – even your eyes closed
Straight from science fiction, these contact lenses that change infringes light into visible light that man can see
People who try a new type of contact designer see flashing infrared signals from a light source.
People have a new way to see Infrared Light, with no need for Clunky Night-Viverery Goggles. Researchers make first contact lenses to inform infrared sight – and devices work even if people close their eyes.
The team behind the invention, LED by Scientists at the University of Science and Technology of China, gave the lenses their power by infusing them with nanoparticles that convert near-infrared light in the 800-1,600-nanometre range into shorter-wavelength, visible light that humans can see, in The 400-700-Nanometre Range. Researchers estimate that lenses cost US $ 200 per pair to do.
The technology, which Detail in the cell on 22 May“Cool cool, like something out of the movie-fiction movie”, says Xiaomin Li, a chemist at Fudan University in Shanghai, China. It opens “new possibilities for understanding the world around us”, he added.

Pros and Cons
Near the first light sitting outside only different lengths that people usually find. Some animals can understand bad light, even though it may not be enough to form images.
Goggles night-views enables people to see infrared radiation, but they are blind and need a source of power to work. The new lenses have not avoided these limits while offering more colorful images of goggles at night, which operate a monochrome green scale, usually not.
However the lens have its own shortcomings. Because those who were embadres were defined light, the images were the lenses of lenses created blurries. The team feature corrects it by placing technology in glasses with additional lenses that change light. Moreover, Unlike Night-Vision Goggles, which amplify light to detect low-level infrared signals, the lenses allow users to see only intense infrared signals, such as those emitted by light-emitting diodes (LEDs).
For these reasons, some critics do not think that lens can be verified. “I can’t think of any application that is not simpler than infrared goggles,” Glen Jenlen, a neuroscientist at the University College London specialist in eye health. “Evolution is avoiding it for a good reason.”
However, the authors think that their lens can further optimize and find a lot of possible use for invention. For example, wearing wearers can read anti-covech mark that releases infrared wavelengths but if not seen in human eye, saying Yuqian co-authorship in USTC.
Li, which is not involved in employment, offering one more possibility: the lenses can be worn by doctors who have been ruined
‘A fun moment’
To make contact lenses, built by scientists previous research where they are Gives rats that have been vindictive vision by injecting nanoparticles to the animals’ retina. At this time, they took the less invasive approach and added nanophintics held by rare metals on the ground including ytrterbium and olbium in a broth of polymer, and then tried them for safety.
The main challenge, Ma said, to pack adequate nanoparticles in the lenses to convert enough forgotten lights, while not changing optical lights, including disabilities found in the strips of lenses, including their transparency.
The rats tests show that animals wearing lenses picking a dark box that is considered ‘safe’ to someone who doesn’t like a box. People who wear lenses see the flowing light from an LED sufficient to two retrieval signals in Morse code and meaning from signals from. The performance of the lens enhanced even when participants close their eyes, because it is nearly damaging to the eyelids, while visible image appearance, can there be a small scale.
“Witnessing people wearing contact lenses and successfully see infrared flashes undoubtedly a fun moment,” Ma said.
Today’s plan now to find ways to upset lenses with lenses and hopes to develop particles that can be improved with technology sensitivity. “We overcame physiological limits in human perspective, as when opening a new window in the new window in the world,” Ma said.
