Clear View Screens were originally developed in the mid 1930s for automobiles as a better option than standard windshield wipers[1] but were soon found more suitable for small boats and larger ships. On ships, a clear view screen or clearview screen is a glass disk mounted in a window, usually on the bridge, that rotates at high speed (~1500 rpm) to disperse rain, spray, and snow. A clear view screen is typically driven by an electric motor at the center of the disk, and is often heated to prevent condensation or icing. Clear view screens are also used in locomotives and rail transport.
