MICHIGAN, US-Researchers have unveiled plans for a smart contact lens that could give its wearer infrared ‘night vision’.

The team say that by sandwiching graphene inside the lens they can build a sensor capable of capturing every from visible light to infrared.

They have already built a prototype smaller than a fingernail, and experts say it could one day be built into lenses for soldiers and others who need to see in the dark.
