The present invention is directed to an article comprising an optical cover assembly. The optical cover assembly comprises: (A) a substrate comprising an outer surface and an opposing inner surface; (B) an optional first coating layer applied directly to at least the outer surface of the substrate; (C) an anti-reflective coating stack comprising at least one coating layer; and (D) a topmost coating layer comprising a fluorosilane polymer on the outer surface of the substrate. The optical cover assembly demonstrates hydrophobicity and extended UV durability, and serves as a component of at least one of a vehicle, a light sensor, a LiDAR detector, a motion sensor, a vision camera, a backup camera, a security camera, an IR camera, a headlight, a taillight, a signal light, a RADAR emitter, a RADAR detector, an aircraft landing light, and a gas detector.
