Chinese scientists have developed contact lenses that will allow you to see in the dark
Scientists from the University of Science and Technology of China have developed unique contact lenses that allow you to see in the dark. About this informs Independent.
Contact lenses work due to nanoparticles, which are able to capture infrared radiation and transform it into light perceived by the human eye.
“Our research opens up the potential for non-invasive wearable devices that give people super vision. There are many potential applications for this material. For example, flickering infrared light could be used to transmit information in security, encryption or anti-counterfeit settings.” – said Tian Xu, the senior author of the study and a neuroscientist at the university.
Contact lenses differ from traditional night vision glasses in that they do not require a power source. Their operation does not depend on whether the user’s eyes are open or closed. Currently, the development can only see infrared light emitted by LEDs, but scientists are continuing to increase the sensitivity of the nanoparticles to enable the ability to see even fainter sources of infrared radiation.
The team of researchers is also working on modifying the nanoparticles so that they can transform different wavelengths of light into different colors. This could be a breakthrough for people with color vision impairment.
“By converting red visible light into something like green visible light, this technology can make the invisible visible to the visually impaired. In the future, we hope to create contact lenses with finer resolution and higher sensitivity.”, – noted Xu.
