Optical polarizing element e.g. polarizing ophthalmic lens, forming method, involves forming layer structure on film support, and placing ophthalmic glass and structure between support surface pressing and inflatable pressing devices

摘要

The method involves forming a polarizing layer structure (30), with a orientation layer, on a film support (31), and placing a ophthalmic glass (40) and the structure between support surface pressing and inflatable pressing devices (10, 20). A portion of an adhesive material is arranged between the structure and the glass. The structure is pressed against a surface of the glass by inflating a membrane of the device (20) and by maintaining a fixed space between the devices. The ophthalmic glass is released and the support is withdrawn so that the structure is stick on the surface. Independent claims are also included for the following: (1) a layer structure comprising a orientation layer (2) a polarizing optical element comprising an optical base element and a layer structure.
