Abstract: An optical system, an eyewear device, and a method of manufacturing the optical system, the optical system comprises a wafer and an optical element. The wafer and the optical element are bonded to each other by an adhesive material, and the wafer has a perimeter shoulder.

Abstract: An ophthalmic lens is provided. The ophthalmic lens includes a first optical surface, an opposing second optical surface and an edge surface connecting the first optical surface and the second optical surface, wherein the edge surface is planar. The ophthalmic lens further includes a first layer disposed on the edge surface, wherein the first layer includes a coating material effective to reduce a reflection caused by a profile of the edge surface, and wherein (a) the first layer defines a structural element for fastening the ophthalmic lens to an eyewear frame, or (b) the ophthalmic lens further includes a second layer disposed on the first layer, wherein the second layer defines a structural element for fastening the ophthalmic lens to an eyewear frame. A method of manufacturing the ophthalmic lens and an eyewear including the ophthalmic lens are also provided.

Abstract: A method of activating and metallising an aromatic polymer film including the steps of: treating a first surface of the film with a basic solution; applying to said first surface of the film an aqueous seeding solution comprising polymer-stabilised catalyst particles; and immersing the film in an electroless plating bath comprising ions of a desired metal so as to deposit a layer of said metal onto the first surface of said film.

Abstract: The present invention relates to a method for electroless deposition of a metal layer on selected portions of a substrate. A preferred form of the invention relates to a method of depositing a desired metal layer, by electroless deposition, on one or more selected portions of an indium tin oxide (ITO) surface of a substrate. These selected portions are typically transparent conductive paths of ITO. The method includes a number of steps including applying a masking layer onto the surface, the masking layer having one or more apertures formed therein so as to expose the one or more selected portions of the surface: exposing the one or more selected portions of the surface to a colloidal suspension of catalytic particles adapted to adsorb to the substrate surface and to enhance deposition of the desired metal layer, and exposing the one or more selected portions of the surface to an ionic solution containing ions of the desired metal to enable formation of the metal layer.
