From the developer:
KnightVision is an astronomy software that changes your video card's color brightness settings. This can be used to change the video settings to something less obtrusive to night vision. Some video cards don't support this function, also known as gamma ramping, but most do. KnightVision notifies you one way or the other. You can select predefined settings in KnightVision, or create your own, depending on how you want to protect your night vision.
