Researchers have created contact lenses enabling infrared vision in humans and mice. These lenses utilize nanoparticles to convert near-infrared light into visible light, requiring no external power source. Tests showed both animals and humans could perceive infrared signals, even with eyes closed. The technology has potential applications in security, communication, and assisting the colorblind by color-coding infrared wavelengths. The lenses currently work best with LED light sources, with future improvements aimed at higher sensitivity and resolution.
