An anti-reflection coating that is soil resistant and easy to maintain is provided on a transparent substrate (10). Optionally, an adhesion-promoting layer (10A) may be provided between the substrate and anti-reflection coating. The anti-reflection coating comprises a multilayer film (11, 12) having: alternating layers of high and low refractive index materials that are transparent over a wavelength region near 550 nm. The multilayer film is formed by reacting metal with non-stoichiometric amounts of oxygen such that the coating has one or more layers of electrically conductive metal oxide material. The resultant conductivity prevents large static potentials from being developed on the coated substrate. The coating is particularly suited for ophthalmic applications.
