To provide a method for manufacturing a spectacle lens having a functional membrane superior in the in-plane uniformity of the film thickness.

A method for manufacturing a spectacle lens applies coating liquid onto a lens base material to form a functional membrane. In this method, application of the coating liquid is performed by a spin coating, and as the coating liquid, a curable composition is used which includes a curable component selected from the group consisting of an organic silicon compound and an acrylate compound and also includes a ketone-based solvent or an ether-based solvent which has a relative vaporization rate of less than 1.00 when an evaporation rate of butyl acetate as an essential solvent is assumed to be 1.00.
