“Surpassing the Evolutionary Boundaries of Biological Photoreception”: Scientists Invent Eyeglasses That Let Wearers See the Infrared in Full Color

Researchers have developed wearable optical devices that expand human vision into the infrared spectrum, translating wavelengths invisible to the naked eye into full-color visible imagery in real time. The technology uses infrared-to-visible light upconversion, a process that absorbs incoming infrared…
