BMW Night Vision introduced in 2005 on the BMW 7 Series (E65). This system processes far infrared radiation, which minimizes non-essential information placing a greater emphasis on pedestrians and animals, allows for a range of 300 meters or nearly 1,000 feet, and avoids "dazzle" from headlights, road lights and similar intense light sources.

But, while driving, the lights work just like standard high beam, low beam headlights. Their adaptive capabilities aren’t enabled here because they still don’t meet US rules.
The Unified Glare Rating (UGR) is a measure of the glare in a given environment, accounting only interior artificial lights, proposed by Sorensen in 1987 and adopted by the International Commission on Illumination (CIE). It is basically the logarithm of the glare of all visible lamps, divided by the background lumination : [18]
Night driving is difficult and dangerous due to the blinding glare of headlights from oncoming traffic. Headlamps that satisfactorily illuminate the road ahead without causing glare have long been sought. The first solutions involved resistance-type dimming circuits, which decreased the intensity of the headlamps.
A prismatic rear-view mirror—sometimes called a "day/night mirror"—can be tilted to reduce the brightness and glare of lights, mostly for high-beam headlights of vehicles behind which would otherwise be reflected directly into the driver's eyes at night. This type of mirror is made of a piece of glass that is wedge-shaped in cross-section ...
glare from bad lighting is a public-health hazard—especially the older you become. Glare light scattering in the eye causes loss of contrast and leads to unsafe driving conditions, much like the glare on a dirty windshield from low-angle sunlight or the high beams from an oncoming car."
The "city light" terminology for front position lights [31] derives from the practice, formerly adhered to in cities like Moscow, London and Paris, of driving at night in urban areas using these low-intensity lights rather than the vehicle's headlights.
The ability to drive without intense concentration (e.g., on highways without intersections or traffic lights [9]) or with few cars on the road [7] It is suggested that highway hypnosis occurs more frequently in experienced drivers and on familiar road sections, as this allows for driving in an automatic mode.
