Researchers have developed new contact lenses that enable vision in the near-infrared range, and they could restore color perception to people with color blindness.

In the future, by working together with materials scientists and optical experts, we hope to make a contact lens with more precise spatial resolution and higher sensitivity.” Cell, 2025. DOI: 10 ...

Nanoparticle-infused contact lenses can transform infrared radiation into different colours of visible light, potentially enabling a new form of night vision – no batteries required ...

Researchers then tested the lenses in both humans and mice. They found that when given a choice of a dark box and an infrared-illuminated box, contact lens-wearing mice chose the dark box, whereas ...

The contact lens technology uses nanoparticles that absorb infrared light and convert it into wavelengths that are visible to mammalian eyes (e.g., electromagnetic radiation in the 400-700 nm range).

“What’s special about our contact lenses is that they let you see infrared light in colour, like red, green and blue — so you can tell different things apart more easily,” he said.

Contact lenses that allow people to see in the dark have been invented by Chinese scientists. The invention allows people to see infrared light, which is normally invisible to the human eye, ...
