First, IANAL.
27602. (a) A person shall not drive a motor vehicle if a television receiver, a video monitor, or a television or video screen, or any other similar means of visually displaying a television broadcast or video signal that produces entertainment or business applications, is operating and is located in the motor vehicle at a point forward of the back of the driver's seat, or is operating and the monitor, screen, or display is visible to the driver while driving the motor vehicle.
Key words are "IS OPERATING". If the Google Glasses were off or he did not see them ON then the ticket should be thrown out. According to what I read the monitor must be turned ON and visible to the driver to be a violation.
