A method, system or computer usable program product for dynamically changing transparency of portions of a vehicle transparent material including determining a location of a bright light with respect to a vehicle; determining a driver location within the vehicle; selectively changing a transparency of a selected portion of the vehicle transparent material to obscure the bright light from the driver's eyes, while allowing a majority of the vehicle transparent material to remain normally transparent; and repeating the above steps continually to adjust a location of the selected portion of the vehicle transparent material as the vehicle changes orientation with respect to the bright light.
