Night vision goggles have been around for decades, but now the  technology is getting so cheap and miniaturized, it might soon be  readily available in more useful places than ever. 
Those cool  dudes at DARPA have done it again, creating a 4-ounce battery and  electronics pack connected to eyeglasses fitted  with a cheap, thin film derived from OLED television screens. Imagine  that, donning the opposite of sunglasses so you can see in the dark.
That super-thin film is just a few microns thick, and it converts  infrared light to the visible spectrum. Within just 18 months, this  spectacular tech will be ready to install in cellphone cameras and car  windshields. The future looks bright, even when it's pitch black dark.
