DarkAdapted modifies your screen gamma settings so that you may, for example, preserve your dark adaptation while using your computer. DarkAdapted is being used by astronomers, planetarium operators, graphics professionals, medical professionals, airline pilots, air traffic controllers, and others worldwide to provide flexible, dynamic control over their monitor's gamma (screen color response).

Users may define an unlimited number of gamma presets, and invoke them via global hotkeys, by menu selection, or by typing the first few letters of a preset’s name.
