Here’s how you could soon be able to see in the dark – even with your eyes closed

Scientists have developed a groundbreaking contact lens that allows wearers to perceive infrared light, enabling them to “see” in the dark, even with their eyes closed. Made from a material similar to regular contacts and embedded with tiny nanoparticles, these lenses detect near-infrared light without the need for batteries. Although they provide a blurry image, they could enhance nighttime visibility and have potential applications in various fields, including healthcare and aiding colorblind individuals, with an estimated production cost of around US$200 per pair.
