Highlights•Transparent UCLs with high NIR-conversion efficiency and biocompatibility were developed•Humans and mice acquire wearable NIR spatiotemporal vision with UCLs•Humans acquire NIR color vision via trichromatic UCLs converting multispectral NIR light•Humans can identify the distinct NIR spectra of images by trichromatic UCLsSummaryHumans cannot perceive infrared light due to the physical thermodynamic properties of photon-detecting opsins. However, the capability to detect invisible multi...
