US EditionInfrared Contact Lenses Enable Vision Beyond the Visible Spectrum
- Scientists from a Chinese research institution have created contact lenses that allow users to perceive infrared light by transforming it into visible wavelengths, enabling vision in low-light conditions without the need for additional power.
- This innovation follows earlier work injecting nanoparticles into mice eyes and aims to provide a less invasive alternative while enabling human infrared vision.
- The contact lenses are embedded with specially designed nanoparticles that absorb near-infrared light within the 800 to 1600 nm range and transform it into visible colors, enabling humans and mice to perceive infrared signals, including their direction and patterned flashes.
- Neuroscientist Tian Xue explains that subjects are unable to perceive any signals without the contact lenses, but once they wear them, they are able to detect flickering infrared light clearly. At present, these lenses are only capable of sensing strong infrared light emitted by high-intensity LED sources.
- While the lenses offer a power-free, lightweight alternative to night-vision devices, challenges remain in improving spatial resolution, sensitivity to ambient infrared, and addressing potential safety risks before wider applications.

Infrared contact lenses enable night vision without bulky goggles
Human vision is limited to a relatively narrow section of the electromagnetic spectrum. Night-vision goggles allow people to see infrared but are bulky and require power. According to a new study in the journal Cell, scientists have developed contact lenses that may one day allow night vision without goggles. — Read the rest The post Infrared contact lenses enable night vision without bulky goggles appeared first on Boing Boing.

Scientists push vision boundaries with lenses that detect invisible infrared light
Scientists in China have developed contact lenses that allow people to see near-infrared light, potentially paving the way for superhuman vision in everyday life. The soft lenses, described in the journal Cell, use upconversion nanoparticles to absorb invisible infrared radiation and convert it into visible red, green or blue light. When worn, users can see infrared signals while still perceiving the full range of normal visible colours — no pow…
