摘要： 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.
