    Abstract: A method for producing a spectacle lens, the method including: determining the positions of at least three marks so as to specify the center position of a frame shape on the basis of the at least three marks; making marks at the determined positions; calculating the shape of a non-optical surface of a semifinished lens with respect to the center position when processing the non-optical surface according to a prescription; and processing the non-optical surface into the calculated shape with respect to the center position. When the semifinished lens is viewed in an optical axis direction, the at least three marks include a pair of marks located on a first straight line passing through the center position and a mark located on a second straight line that is orthogonal to the first straight line and passes through the center position.

    Abstract: The spectacle lens has at least a lens base material, and a multilayer film positioned on an eyeball-side surface of the lens base material, in which an average reflectance Rm (280-380) in a wavelength region of 280 to 380 nm, measured on the eyeball-side surface of the spectacle lens, is 10.0% or less, and a chroma C*, measured on the eyeball-side surface of the spectacle lens under a CIE standard illuminant D65, is 0.5 or more but 5.0 or less.
