Infrared contact lenses for humans and mice transform eyelids into see-through night-vision screens, using nanoparticles that convert near-infrared light into visible hues. Developed by neuroscientists in 2025, these nontoxic, power-free lenses let users perceive both visible and color-coded infrared wavelengths, even with their eyes closed. "Super-vision" is now wearable tech.

Test subjects with these contact lenses detected morse code–style flashes and tracked invisible light directions, a feat impossible without the lenses. Related searches like 'night vision contacts' and 'infrared eye tech' spike as researchers show eyelid-penetrating infrared boosts detection, and mice pick dark boxes over glowing ones—eyes closed, vision rewired.

A single pair of these contacts can turn 980 nm infrared into blue, 808 nm into green, and 1,532 nm into red—color-coding invisible worlds.
