Another Aussie first

Scientists at the Australian National University (ANU) have developed a new type of night-vision technology that is the first of its kind. Taking the form of an ultra-thin film, it can be applied directly to glasses to act as a filter, needing only a simple laser to convert infrared light into images the wearer can see.

The ANU team's nanocrystal can be used to create night vision devices that forgo electricity completely, by converting incoming photons from infrared light into other photons on the visible spectrum, to allow the human eye to see in the dark.
"Current night vision glasses are a combination of optics and electronics," Mohsen Rahmani, co-researcher on the study, tells New Atlas. "They receive the near-infrared spectrum, which is not visible, and convert photons to electricity. But with this technology, we don't need electricity anymore, we directly convert light to light, we just change the color and the frequency."
