CHINA: A team of Chinese researchers has created groundbreaking contact lenses that enable wearers to perceive near-infrared light, opening the door to what they call “super-vision” for everyday use.
Unlike traditional night vision technology, these lenses are soft, transparent, and functional even in daylight without needing an external power source.
Published in the journal Cell, the study reveals that the lenses contain upconversion nanoparticles capable of absorbing invisible infrared radiation and converting it into visible red, green, or blue light.
Users can see both standard colors and additional infrared signals, all through regular contact lens wear.
Non-Invasive Vision Enhancement
Professor Tian Xue, a neuroscientist from the University of Science and Technology of China, described this advancement as a potential breakthrough for augmented human vision.
The innovation might also offer practical benefits to people with color blindness by transforming undetectable wavelengths into perceivable colors.
Team member Dr. Yuqian Ma emphasized the broader implications, noting that over half of the Sun’s energy arrives in the form of infrared radiation—normally invisible to the human eye. “
Our research moves us closer to experiencing parts of the world previously hidden from view,” Ma said.
Early Testing Shows Promise
In trials, volunteers wearing the lenses could distinguish signals sent via infrared LEDs in Morse code and detect the direction of an infrared light source—even with their eyes closed, as eyelids block visible light more than infrared.
Currently, the lenses do not detect far-infrared radiation, such as body heat, but future improvements in nanoparticle efficiency could change that.
The team hopes this technology may eventually allow humans to perceive a wider spectrum of light naturally.
Beyond scientific interest, the lenses have potential real-world applications, from revealing secret codes and messages to enhancing augmented reality experiences, providing wearers with access to visual information invisible to others.
