Glasses Grant Wearers Infrared Vision

⊲ Popular Science ⊳ Engineers at the Beijing Institute of Technology have built infrared-sensing glasses that let wearers see infrared light alongside normal vision. The 23-gram prototype uses mercury telluride quantum dots to capture infrared photons, converting them into electrical charges fed into an OLED layer built into the lens. Different wavelengths appear as red or red-cyan hues, letting users view infrared and visible light through one eye simultaneously. The researchers describe the work as a step towards visual prosthetics, augmented reality and better navigation in poor visibility, though the current design remains a bulky lab prototype rather than a consumer product.
⊲ Framing infrared perception as a step toward visual prosthetics suggests defence and medical applications may follow well before consumer adoption. ⊳
