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.

The present invention relates to a polarization filter for ophthalmic lenses. The polarization filter comprises a mesogen layer coated onto a retardation film, either directly or through an adhesive layer. The present invention further discloses that the polarization filter formed by employing a thin film or sheet, having a defined level of retardation between the light source and the mesogen layer, for example, a cholesteric mesogen layer, the multilayered laminate structure demonstrates linear polarization of the light transmitted through the mesogen laminate structure, and, hence, can be used in ophthalmic lenses, e.g. spectacle or eyeglass lenses. The polarization filter enhances the performance by allowing transmission of the polarization filter closer to the theoretical maximum transmission.

Mesogen polarizer

Optical devices such as eyeglass lenses and digital displays having improved optical characteristics achieved, in part, through incorporation of an index matching system between material layers having different refractive indices.

Index matching layers

An anti-reflective coating system configured to resist crazing resulting from applied compressive forces, and an optical article employing the anti-reflective coating system; and methods of forming the same. The methods include forming a first anti-reflective coating over a first surface of the optical article and applying a second anti-reflective coating over a second surface of the optical article, where the second anti-reflective coating has substantially the same reflectance than the first anti-reflective coating and a mechanical property distinct from the first anti-reflective coating.

Crazing resistant coating and method thereof

An anti-reflective, anti-static coating, optical articles employing such a coating, and methods of forming the same. The coating formed of alternating layers of low, mid, and/or high refractive index oxide materials and one or more layers of electrically conductive, substantially non-oxide forms of the same materials employed to form the alternating layers of low, mid, and/or high refractive index oxide materials.

Anti-static, anti-reflective coating

An optical filter providing selective transmittance of target wavelengths of light and tunable, differential front and back surface reflectance.

Optical filter with selective transmittance and reflectance

An anti-reflective coating system configured to resist crazing resulting from applied compressive forces, and an optical article employing the anti-reflective coating system; and methods of forming the same.
