This disclosure relates to a motor vehicle cabin sensing system. The system comprises an image sensor, an illumination source and an illumination lens array. The image sensor is operable to capture one or more images, the image sensor having a field of view of a motor vehicle cabin. Preferably, the image sensor is operable to capture images in a near infrared wavelength. The illumination source is operable to transmit light rays towards the motor vehicle cabin. The illumination lens array is operable to diffuse the light rays emitting from the illumination source to one or more photoreceptor cells of a retina such that a radiant intensity of a red glow effect detected by the retina is a reduction of 10 to 100 times or 0% to 50% of a radiant intensity of the illumination source.
