    Abstract: A polarizing optical element comprises a transparent optical base element and a layered structure that incorporates a polarizing film. The polarizing film is of the dichroic dye type and is oriented uniaxially. The layered structure is bonded to the optical base element by means of a layered structure that includes at least one layer of a pressure-sensitive adhesive. Thanks to the use of pressure-sensitive adhesive, the polarizing film during the bonding operation maintains a high polarization efficiency and an optical quality compatible with many applications of the optical element, especially ophthalmic applications.

    IPC: G02C7/12

    Abstract: A transparent and polarizing vision element (2) divided into several areas. At least two of said areas are associated with a luminous polarization filter. The light flowing through the element is allocated differently for two the areas according to a direction of polarization of the light. At least one polarization filter is oriented vertically, and at least one polarization filter is oriented horizontally in relation to the usual position of the element.

    Abstract: The method involves forming a polarizing layer structure (30) on a temporary support (31), on which an intermediate coating layer (32) is placed, where the polarizing layer structure comprises an orientation layer (34) and a polarizing layer (35) with dichroic colorant. The polarizing layer structure is removed from the temporary support for obtaining the structure in the form of a self-supported membrane. The polarizing layer structure is applied on a surface of a base optical element e.g. ophthalmic lens. Independent claims are also included for the following: (1) a polarizing layer structure comprising an orientation layer (2) an optical polarizing element comprising a polarizing layer structure.

    Abstract: The inventive method consists in transferring a pattern (P) onto the optical article (1) in the form of one or several portions of transferable material (3) retained by a pressure-sensitive adhesive material layer (2) and in applying transferable material portions with the aid of a pad by placing the adhesive material layer between the pad and a pattern receiving article. The use of the pressure-sensitive adhesive material makes it possible to use the different materials in the form of a transferable material. Said method is particularly suitable for producing patterns, in particular in the form of holograms on optical lenses, in particular ophthalmic lenses.
