In a nutshell A new smart contact lens can monitor both eye pressure and eye movement, even while your eyes are closed, ...

Although there already are "smart" contact lenses that monitor the eyes for signs of glaucoma, the devices are typically only ...

Contact lenses have enabled people to see beyond the visible light range, picking up flickers of infrared light even in the dark – or with their eyes closed. The lenses contain engineered ...

Combining regular lens technology with nanoparticles, researchers have created prototypes of contact lenses that allow people to see in the dark — and through their eyelids.

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 ...

Researchers say trial participants could perceive information in infrared light even when they closed their eyes ...

The lenses were tested on both mice and humans, and the results suggest this technology could one day replace bulky night vision gear with something much more discreet.

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 ...
