Beschreibung
Zusammenfassung:	An optical element, which is transparent, for a motor vehicle, including at least one transparent first layer containing a polymer material and at least one second layer including at least silicon, titanium and oxygen. The optical element has a surface roughness defined by a mean square deviation Rq greater than or equal to 20 nm.
