Overview

• The contact lenses, created by an international team led by Chinese scientists, enable infrared vision without external power or bulky equipment.
• Nanoparticles embedded in the lenses convert infrared light into visible colors, allowing simultaneous perception of both spectrums.
• Human trials demonstrated the ability to detect blinking infrared signals and their direction, with improved sensitivity observed when eyes were closed.
• Current limitations include low spatial resolution and sensitivity to only strong infrared sources, prompting development of complementary glasses for enhanced clarity.
• Potential applications range from night vision for professionals to medical imaging, security, and aiding individuals with colorblindness.
