Ultra-thin film could one day turn regular glasses into night vision goggles, researchers say

Developed by Australian and European researchers, the film works by converting infrared light into light visible to the human eye

A transparent metallic film allowing a viewer to see in the dark could one day turn regular spectacles into night vision googles.

The ultra-thin film, made of a semiconductor called gallium arsenide, could also be used to develop compact and flexible infrared sensors, scientists say.
