An international research team, headed by Chinese scientists, has successfully developed contact lenses that enable humans to perceive near-infrared light. The findings were published in the scientific journal Nature Communications. The newly created contact lenses incorporate nanomaterials capable of converting near-infrared light into visible light, making it possible for the human eye to detect wavelengths that are normally invisible. According to the researchers, this innovation could have important applications in fields such as medical imaging, where the ability to see near-infrared light can enhance diagnostic capabilities. Additionally, the technology may be used in visual assistance devices to aid individuals with vision impairments. The development represents a significant step forward in wearable optical technology, potentially opening new avenues for both medical and consumer uses. The study was conducted by an international team, with leadership from scientists based in Hefei, China.
