Optical multilayers, lenses, and display methods

Abstract

Light shielding refers to a multi-layered optical film that can achieve a reduction in the weight of virtual reality (VR) protective glasses and improve their visibility. The multilayer optical impregnation scheme of the invention is a multilayer optical impregnation consisting of: a multilayer thin film (31) comprising the substrate and the surface-treated layer; and a retarding detail (22), in which the substrate of the multilayer thin film and the retarding detail are arranged closely together, in which the retarding detail includes the first retarding layer (22a), the adhesive layer (50), and the second retarding layer (22b) in the order mentioned above, and in which the adhesive layer has a thickness of 0.5 pm or greater and 1.3 pm or less.
