Abstract: An object is to not lose an effect of suppressing the progression of myopia or hyperopia even in a peripheral area of a spectacle lens. A spectacle lens and a technology related thereto are provided, the spectacle lens including: a first area that causes light rays incident on an object-side face of the lens to exit from an eyeball-side face of the lens and to converge at a predetermined position A on a retina of a wearer; and a plurality of second areas configured to cause light rays to converge at a position B on the object side or a position C on the distal side relative to the position A, wherein, in the first area in a peripheral area of the spectacle lens that is a radius range from 4.5 mm to 25 mm of a lens center, a refractive power error in a meridional direction and a refractive power error in a sagittal direction have values that cause light rays to converge in a direction extending from a vicinity of the position A toward the position B if the second areas cause the light rays to converge at the position B, or have values that cause light rays to converge in a direction extending from the vicinity of the position A toward the position C if the second areas cause the light rays to converge at the position C.

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: 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.
