Researchers have developed nanotechnology contact lenses that allow humans to see in the dark and even with their eyes closed by converting invisible infrared light into visible images, as detailed in a study published in *Cell*. The lenses, infused with nanoparticles, enable wearers to see infrared images in color, enhancing visual perception, particularly in low-light conditions. Future research aims to test these lenses on a more diverse population and explore their potential applications in various fields, including emergency response and medical imaging.
