A substantially optically transparent article such as a lens having a wear-resistant surface comprises a substantially optically transparent polymeric substrate (e.g., a polycarbonate or polymethyl methacrylate substrate), and having a surface portion. A hard antiabrasive interconnecting layer is formed on the surface portion (typically by vacuum deposition and preferably by plasma-enhanced chemical vapor deposition), and a lubricious hydrophobic coating layer is bonded to the interconnecting layer. The lubricious hydrophobic coating layer, together with the hard antiabrasive interconnecting layer, form a wear-resistant surface on the substrate. The lubricious coating layer is formed from a hydrophobic organic lubricant such as a perfluoropolyether, a fatty acid, or a fatty acid esters. Methods of making such articles are also disclosed.
