摘要： A method of manufacturing an optical article, wherein an output light flux generating process of generating an output light flux by inputting a light from a light source to an output setting element having a repetition structure; a cured layer forming process of forming a cured layer at an irradiation area that is formed in correspondence with the output area by introducing the output light flux through a projection optical system into a container in which light-curable resin is contained and a stage is arranged and condensing the output light flux; and a stage moving process of moving the stage in a desired distance along the direction of the output flux propagating, are sequentially performed in this order and an irradiation variation process of varying the irradiation area in the cured layer generating process are further included, thereby the optical article is formed on a surface of the stage.

摘要： Disclosed is a method for marking an optical article coated with an interference coating including at least two layers, an inner layer and an outer layer, and having reflection coefficient Re; by exposure of the inner layer, at a marking point, by way of a laser beam at a marking wavelength, in such a way as to ablate the inner layer and any layer further away from the substrate; the ablated area having a reflection coefficient Rm different from Re by at least 1%; the inner layer absorbing the marking wavelength to a greater degree than any layer further away from the substrate. Also disclosed is an optical article coated with an interference coating having at least two layers, an inner layer and an outer layer, the article including a marking pattern formed by local absence of layers.

摘要： A method for determining a position variation of an eyewear equipment worn by a wearer includes obtaining reference data representing a reference position of an eyewear equipment worn by the wearer, the eyewear equipment including at least one ophthalmic lens and a frame on which the at least one ophthalmic lens is mounted, determining at least one reference position parameter indicative of a reference position of the eyewear equipment on the face of the wearer based on the reference data, obtaining current data representing a current position of the eyewear equipment worn by the wearer, determining at least one current position parameter indicative of a current position of the eyewear equipment in front of the eyes of the wearer based on the current data, and comparing the reference and current positions parameters to determine a position variation of the eyewear equipment worn by the wearer.
