Scientists at the University of Michigan have developed a night vision contact lens:

The University of Michigan has developed a prototype contact lens that enhances night vision by placing a thin strip of graphene between layers of glass. The graphene — a form of carbon — reacts to photons, which makes dark images look brighter.

The development of the lens still has quite a ways to go before soldiers can scrap those heavy goggles. Right now the graphene only absorbs 2.3 percent of the light. Those percentages have to rise before true night vision can be achieved.

It’s kind of neat, but wicked creepy.
