Why in news
Scientists have created special hydrogel contact lenses that let humans see near-infrared (NIR) light.
These lenses contain nanoparticles that convert low-energy infrared light into visible light (red, green, and blue).
They can upconvert infrared light at 808 nm, 980 nm, and 1,532 nm wavelengths.
The lenses are made from biocompatible materials, safe for use in the human body.
These lenses could help first-responders locate victims during disasters by seeing through smoke or darkness.
Infrared light in the 800–1,600 nm range can pass through water-rich tissues, allowing doctors to view internal body features without needing cameras or scopes.
