Researchers have created innovative contact lenses that enable wearers to see infrared light, a portion of the electromagnetic spectrum invisible to the human eye. Unlike night vision goggles, these lenses are transparent and do not require a power source. The technology aims to extend human vision, which currently sees only a tiny fraction of the spectrum. The lenses could also assist individuals with color blindness. This breakthrough utilizes upconversion nanoparticles to convert infrared light into visible wavelengths, exemplifying a push towards enhancing human sensory experiences.
Prof Tian Xue stated, "The work paved the way for a range of contact lenses, glasses, and other wearable devices that give people super-vision."
Dr Yuqian Ma emphasized, "Over half of the solar radiation energy, existing as infrared light, remains imperceptible to humans."
