A team of neuroscientists and materials scientists has created innovative contact lenses that grant the ability to perceive infrared light to both humans and mice. These lenses function by converting infrared light, which is normally invisible to the human eye, into visible wavelengths. The research, published in the journal Cell, demonstrates that the technology can be integrated into soft contact lenses, providing a lightweight and unobtrusive alternative to traditional infrared night vision goggles. Unlike conventional night vision devices, which are bulky and require external power sources, these contact lenses are designed to be worn directly on the eye and do not rely on external equipment. The study involved testing the lenses on both laboratory mice and human subjects, showing successful conversion of infrared signals into visible images. This advancement could have applications in security, military, medical imaging, and other fields where enhanced vision in low-light or infrared environments is beneficial.
