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 easy-cleaning coating, an easy cleaning coating having anti-fogging properties, and an easy-cleaning, anti-reflective coating.

Easy-clean coating

A photochromic polyurethane laminate that is constructed to solve certain manufacturing difficulties involved in the production of plastic photochromic lenses is disclosed. The photochromic laminate includes at least two layers of a resinous material and a photochromic polyurethane layer that is interspersed between the two resinous layers and which contains photochromic compounds. The polyurethane layer is formed by curing a mixture of a solid thermoplastic polyurethane, at least one isocyanate prepolymer, at least one photochromic compound, and a stabilizing system.

Photochromic polyurethane laminate

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