Cutting-Edge Contact Lenses Allow People to Detect Invisible Infrared Light, Even with Their Eyes Shut
Researchers have created revolutionary contact lenses that enable individuals to detect infrared light, a spectrum that was formerly imperceptible to the human eye. This advancement utilizes “upconversion nanoparticles” that function by absorbing infrared light and transforming it into visible light in red, green, and blue, thereby expanding human color perception beyond its natural scope. In contrast to traditional night-vision equipment, […]
