Abstract: An ophthalmic article having a coating system which provides antireflective, easy clean and anti-fogging properties to the ophthalmic article. The coating system includes alternating layers of low refractive index and high refractive index metal oxides and a sol-gel based hydrophilic top layer formed of one or more silanes, one or more alcohols, DI water and itaconic acid. The coating system provides favorable surface energy and particle size distribution to the ophthalmic article when the sol-gel based top layer is deposited on top surface of the alternating layers of low refractive index and high refractive index metal oxides.
