Abstract: Provided is technology that makes it possible to measure visual behavior with respect to objects that are at different distances in the depth direction, while reducing burden on a subject. A method for measuring visual behavior of a subject to design an eyeglass lens includes: a step (a) of ascertaining a head rotation amount that is generated by the subject in a sagittal plane of the subject when gazing at each of a plurality of gaze points that are set at predetermined distances different from each other in a forward depth direction; and a step (b) of determining an eyeball rotation amount that is generated by the subject when gazing at each of the plurality of gaze points, based on the head rotation amount.

Abstract: A method is provided for producing an optical member. The method includes removing a portion of a low refractive index layer, which is the outermost layer of a multilayer structure in which the low refractive index layer and a high refractive index layer are layered on each other. Non-heating processing is performed on an antireflection film that is formed to cover an optical surface of an optical base member and has the multilayer structure, through irradiation with an ultrashort pulse laser beam, so as to expose the high refractive index layer.

Abstract: Provided is an eyeglass lens 1 configured to cause rays that have entered from an object-side surface 3 to be emitted from an eyeball-side surface 4, and cause the emitted rays to converge at a predetermined position A. The eyeglass lens 1 includes a lens base material 2 having a plurality of base material convex portions 6 on at least one of the object-side surface 3 and the eyeball-side surface 4, and a coating film covering the surface provided with the base material convex portions 6. The shape of convex portions present on the outermost surface of the eyeglass lens located on a side on which the base material convex portions 6 are provided is an approximate shape of the base material convex portions configured to cause rays that have entered the eyeglass lens 1 to converge at a position B that is closer to the object than the predetermined position A is.

Abstract: A method of processing a spectacle lens that has an electronic element overlapping an optical element and supplies electric energy to the electronic element through a terminal portion to produce a dimming effect, the method including: acquiring inner dimension information of a retaining portion of a frame, the retaining portion sandwiching and retaining a periphery of the spectacle lens between a front and a rear; acquiring thickness information of the periphery of the spectacle lens processed into an external shape corresponding to the frame; determining an interference area of the periphery of the spectacle lens; and performing thickness adjustment processing for removing the interference area, on a surface on the other side of the spectacle lens opposite to the surface on the one side of the spectacle lens. This configuration enables easy assembly of a spectacle lens to a frame without being restricted by the thickness of a lens periphery.

Abstract: A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.
