Abstract: A method for controlling the transparency level in smart glass is provided. The method includes receiving a signal indicative of an ambient light intensity from a sensor in a smart glass, selecting a transparency level for an eyepiece in the smart glass based on the signal, and providing the transparency level to a control circuit so that the eyepiece can receive a desired current to activate a dimming device in the eyepiece to a desired level.
