Abstract: Provided is an eyeglass lens configured to cause rays that have entered from an object-side surface to be emitted from an eyeball-side surface and cause the emitted rays to converge at a predetermined position A. The eyeglass lens includes a lens base material having a plurality of base material convex portions on at least one of the object-side surface and the eyeball-side surface, and the eyeglass lens has a configuration for suppressing stray light rays that do not pass through the vicinity of the predetermined position A or the vicinity of the position B that is closer to the object than the predetermined position A is.

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: Provided are a spectacle lens and a technique associated therewith, the spectacle lens including: an object-side surface and an eyeball-side surface; a first refractive region having a first refractive power based on a prescription for correcting a refractive error of an eye; and a second refractive region having a refractive power different from the first refractive power, the second refractive region having a function of forming a focal point at a position other than a retina of the eye so as to suppress progression of the refractive error of the eye, wherein an interface portion is disposed inside the spectacle lens, the interface portion includes a base portion, and convex portions protruding from the base portion, or concave portions recessed from the base portion, the function of the second refractive region is exerted by using mutually different respective refractive indexes of two types of members sandwiching the interface portion therebetween, and the convex portions or the concave portions, and an outermost surface portion of the spectacle lens that corresponds to the convex portions or the concave portions is smooth.

Abstract: A pair of right and left spectacle lenses each includes: a distance vision region and a near vision region; and a progressive region in which a refractive power progressively changes between the distance vision region and the near vision region. In the pair of right and left spectacle lenses mounted in a spectacle frame, a height position of a distance eye point that is a reference point of the distance vision region is different between right and left, and a corridor length connecting the distance vision region and the near vision region is different between right and left.
