New lenses turn invisible infrared light into visible images, a study found. Humans can now see in the dark -- and even with their eyes closed -- using nanotechnology contact lenses that turn ...

In previous research, some of the same scientists gave mice infrared vision by injecting the nanoparticles directly into their eyes. Contact lenses are, clearly, a less invasive option.

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 range).
