Article

Scientists have created contact lenses that let people see in the dark. These special lenses use tiny particles called nanoparticles and do not need a battery or power source. They can even work when your eyes are closed, because infrared light goes through your eyelids better than normal light.

The lenses were first tested on mice and then on people. Testers could see flickering infrared light and tell its direction. This invention could help in emergencies, rescue missions, or even stop fake goods. The researchers believe these lenses could be used in many real-life situations — not just in science fiction films.
