Spectacular Invention: Scientists Give People Super Eyes with Groundbreaking Lens

A team of Chinese scientists has developed a lens that allows people to see light that is normally invisible to the human eye—even with their eyes closed. The breakthrough involves the use of upconverting nanoparticles embedded in contact lenses, which convert infrared light into visible light. This technology could revolutionize night vision and aid in various professional fields such as firefighting and navigation in low-light conditions.
