A system for reducing glare in a vehicle includes a windshield treated with a coating, an external light sensor configured to detect a position of a light source external to a vehicle, an eye sensor configured to detect a location of an eye of an operator of the vehicle. The system also includes an emitter configured to excite a location of the coating on the windshield from a first state to a second state that is more opaque than the first state. The system further includes a processor programmed to determine the location of the coating for exciting based on the detected position of the light source and detected position of the eye, and to control the emitter to selectively excite the coating at the location from the first state to the second state.
