(by night vision, I mean natural night vision)
While I can understand that using white or yellow light can blind a person (temporarily) during night time operations, how come cockpits of aircraft and the bridges of ships are lit red in order to preserve night vision? Why not green, or blue, or something else (anything but white/yellow)?
