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.

Abstract: A method for producing a spectacle lens 2 including a base portion 2 that is made of a resin material and includes a convex object-side face and a concave eyeball-side face, and an optical element 12 that is made of a material different from the material for forming the base portion and is embedded in the base portion, is described. The method includes: arranging an optical element in a cavity 28 of a mold including a first mold part 20 and a second mold part 24 that can be opened and closed; introducing a resin material for forming a base portion of the spectacle lens into the cavity of the mold; obtaining the spectacle lens by curing the resin material that is a resin for forming the base portion; disassembling the mold; and detaching the spectacle lens from the mold.

Abstract: A binocular visual function measurement method includes a visual target presentation step of presenting a right eye image to be viewed by the right eye of a measurement subject and a left eye image to be viewed by the left eye of the measurement subject to the subject in a space where real space information is blocked out; a presentation control step of changing positions where the right and left eye images are presented, relative to each other; a timing detection step of detecting a timing at which the measurement subject is unable to fuse the right and left eye images when the presentation positions are changed; and a parameter value calculation step of calculating a predetermined parameter value regarding a binocular visual function of the measurement subject based on a relationship between the relative positions of the right and left eye images when the timing is detected.

Abstract: An object is to provide a polarizing lens in which a polarizing function differs depending on the region of the surface of the lens. A polarizing lens that includes a polarizing layer on a lens base material and that includes a region in the surface of the lens in which the degree of polarization caused by the polarizing layer continuously differs or a region in the surface of the lens in which the film thickness of the polarizing layer continuously differs.

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.
