Scientists have developed contact lenses that allow wearers to see infrared light, offering night vision capabilities.
The lenses use nanoparticles to convert infrared light into visible wavelengths, eliminating the need for bulky night-vision goggles.
Experiments on mice and humans have shown successful perception of infrared light, with the potential for color distinction within the infrared spectrum.
Future developments aim to enhance spatial resolution and sensitivity of the lenses for broader practical applications in emergency and security scenarios.
