A method of designing an ophthalmic lens, comprising the steps of: determining specifications of a temporary lens such that the temporary lens gives an optical power required by a wearer of the ophthalmic lens; applying the temporary lens to a prescribed schematic eye, and effecting emmetropization of an optical system consisting of the temporary lens and the schematic eye; obtaining an optical characteristic of the optical system at a position of an optical axis of the temporary lens which is offset from an optical axis of the schematic eye by a predetermined offset amount; obtaining successively optical characteristics corresponding to different configurations of the temporary lens with the axes of the temporary lens and the schematic eye being offset from each other by the predetermined offset amount; selecting optimum one of the different configurations of the temporary lens which gives optimum one of the successively obtained optical characteristics; and determining specifications of an intended ophthalmic lens as a final product, based on the selected optimum configuration of the temporary lens. <IMAGE> |
