'Super-Vision' Contact Lenses Let Wearers See in the Dark — Even with Their Eyes Closed
- On May 22, 2025, a team of scientists in China unveiled contact lenses that enable users to perceive infrared light, which is typically invisible to the human eye.
- The lenses incorporate nanoparticles that capture near-infrared light within the 800 to 1,600 nanometer range and emit it as light detectable by the human eye, all without requiring an external power source.
- Tests on mice showed sensitivity to infrared light through pupil response and preference, while human trials demonstrated perception of flickering infrared LED light and detection of its direction, especially with eyes closed.
- Tian Xue, lead neuroscientist, explained that the individual is unable to perceive any visuals without the special contact lenses, but once worn, they can distinctly detect the blinking of infrared light, suggesting promising applications in areas like security and emergency response.
- While promising for enhancing vision and aiding colorblindness, the lenses currently only detect bright LED infrared light, have limited image resolution, and require further improvements before practical everyday use.

How new infrared contact lenses can help people see in the dark
Researchers at the University of Science and Technology of China have developed special infrared contact lenses that allow people to see in the dark. Unlike night vision goggles, these lenses require no power and can even function with closed eyes. The researchers of the study said that the technology could also benefit people with colour blindness
They Create Contact Lenses that Allow You to See Infrared Light, Even with Your Eyes Closed
The device, which converts infrared light into visible light within the lens, allows to distinguish light signals and opens the door to expanding the sensory reality of humans Hemeroteca - They discover a new color inside the retina: there is a chromatic palette to be explored inside the eye Neuroscientist Tian Xue and his team from the University of Science and Technology of China have just presented a breakthrough that looks like science ficti…
