Infrared Contact Lenses Give Humans Night Vision
2025-05-23
Scientists have created contact lenses that grant infrared vision to both humans and mice. These power-free lenses convert infrared light into visible light, allowing wearers to see both infrared and visible light simultaneously. The lenses use nanoparticles to convert near-infrared light (800-1600 nm) into the visible spectrum (400-700 nm), and can even differentiate between various infrared wavelengths. While currently limited to detecting infrared from LED sources, future iterations aim for improved sensitivity and resolution, potentially aiding those with color blindness. Tests showed enhanced infrared perception with eyes closed due to better eyelid penetration of near-infrared light.
