Overview

• Researchers have developed soft contact lenses infused with nanoparticles that convert near-infrared light into visible light, enabling functional night vision.
• Human trials demonstrated the ability to detect Morse code-like infrared flickers, track directional beams, and perceive infrared signals more effectively with eyes closed.
• Animal tests showed mice wearing the lenses avoided infrared-lit areas, confirming the lenses' ability to detect infrared light.
• The lenses feature a color-coding function, translating different infrared wavelengths into distinct visible colors, potentially aiding color-blind individuals.
• While current prototypes work only with high-intensity LED sources and produce blurry images, researchers aim to improve ambient infrared sensitivity and spatial resolution for broader applications.
