Snooperscope promises to add night vision to your Android device

An add-on for a smartphone or tablet that promises to bring night vision to your Android devices. Similar to a security camera, the module uses infrared light to allow you to see in very low light conditions.

Interesting application of tech but what problem does it solve? When do smartphones/ tablets need night vision rather then a a flashlight app? Still it might be a fun stocking stuffer (use it once and forget about it) for next Christmas.
