Abstract
An ophthalmic article having a coating system which provides antireflective and easy clean properties to the ophthalmic article. The coating system includes alternating layers of low refractive index metal oxide and high refractive index metal oxynitrides and corresponding high refractive index metal oxides. The coating system provides favorable surface energy to the ophthalmic article when at least one layer of the high refractive index metal oxynitride is encapsulated between two layers of low refractive index metal oxide.
