A team in China has woven tiny, light-converting particles into soft contact lenses, granting wearers the power to perceive infrared light both in the dark and, surprisingly, with their eyes closed. The “seeing with your eyes shut” part arises because near-infrared light penetrates the eyelid more effectively than visible light.

Nanoparticle-infused contact lenses can transform infrared radiation into different colours of visible light, potentially enabling a new form of night vision – no batteries required

Neuroscientists and materials scientists have developed new contact lenses that give people infrared vision, allowing them see in the dark, even with
