Provided is a method for manufacturing a spectacle lens, wherein: the spectacle lens includes a lens substrate having microprotrusions on at least one surface, and a coating film formed on the surface of the lens substrate that has the microprotrusions; and the method includes forming the coating film by applying an application liquid, through spin-coating, to the surface of the lens substrate that has the microprotrusions.

Method for manufacturing spectacle lens

Provided are an eyeglass lens that includes a lens substrate having a plurality of substrate protruding portions that protrude from a substrate base portion on a surface of the lens substrate and a coating film provided so as to cover the plurality of substrate protruding portions, the outermost surface of the eyeglass lens having a plurality of convex portions and concave portions, in which the thickness of the coating film varies over the surrounding regions of the substrate protruding portions, and technology related thereto.

Eyeglass lens

Provided is an eyeglass lensconfigured to cause rays that have entered from an object-side surfaceto be emitted from an eyeball-side surface, and cause the emitted rays to converge at a predetermined position A. The eyeglass lensincludes a lens substratehaving a plurality of substrate convex portionson at least one of the object-side surfaceand the eyeball-side surface, and a coating film covering the surface provided with the substrate convex portions. The shape of convex portions present on the outermost surface of the eyeglass lens located on a side on which the substrate convex portionsare provided is an approximate shape of the substrate convex portions configured to cause rays that have entered the eyeglass lensto converge at a position B that is closer to the object than the predetermined position A is.

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.

Spectacle lens and method for manufacturing same

Provided are a method for manufacturing an eyeglass lens that includes a lens substrate having a plurality of substrate protruding portions that protrude from a substrate base portion on a surface of the lens substrate and a coating film provided so as to cover the plurality of substrate protruding portions, the outermost surface of the eyeglass lens having a plurality of convex portions and concave portions, the method including forming the coating film by immersing the lens substrate in a coating film liquid, pulling up the lens substrate, and drying the coating film liquid on the lens substrate while or after the coating film liquid flows under its own weight, and technology related thereto.
