Overview

• Scientists at the University of Science and Technology of China have developed contact lenses that convert infrared light into visible colors using nanoparticle technology.
• The lenses enable users to see infrared signals even with closed eyes, as demonstrated in tests with both mice and humans.
• Currently, the lenses can detect strong infrared sources like LEDs, with researchers working to improve sensitivity to weaker signals such as body heat.
• Potential applications include night vision, medical diagnostics, and aiding individuals with color vision deficiencies by converting infrared into visible light.
• The technology utilizes a flexible polymer material enriched with gold nanoparticles and ions, marking significant progress in wearable nanotechnology.
