A vehicle occupant safety system 100 includes a display layer 124 and an in-vehicle monitoring device 102. The in-vehicle monitoring device includes an image sensor 106 and an image light source 108. The image sensor captures and generates one or more images. The image light source transmits light rays through the display layer. The in-vehicle monitoring device is displaced posterior to the display layer. The image light source includes an optical layer 112 having multiple microstructures 408. The optical layer is displaced anterior to the image light source. The optical layer may be displaced at a distance L from the image light source and may include a long pass optical filter. The distance L may be selected from a range of at least one to two times more than a size of an aperture of the image light source. The distance L may be between 6-20mm. Controlling a vehicle occupant safety system includes detecting an eye gaze of a vehicle occupant using this device. In response to detecting the eye gazing towards / away from a display direction of the vehicle occupant safety system, an eye gaze display algorithm 118 executes an instruction set on a processor 104 switching the display on / off.
