The coated substrate product finds particular application in eyeglass and sunglass lenses, architectural glass, analytical instrument windows, automotive windshields and laser bar code scanners for use in retail stores and supermarkets. The product has greatly improved wear resistance for severe abrasive environments and comprises a substantially optically transparent substrate, one or more chemically vapor deposited interlayers bond to the substrate and a chemically vapor deposited outer layer of optically transparent or substantially optically transparent hard and low friction material bonded to the interlayer and away from the substrate.
