Abstract: A plurality of to-be-evaluated lenses that differ in lens surface design from one another is prepared in an evaluation-value calculating step. Thereafter, a subject's predetermined biological information, e.g., brain waves, is measured for each of the to-be-evaluated lenses by allowing the subject to wear each of the lenses, and an evaluation value for each of the lenses is calculated relative to a predetermined index in the brain waves, for example, relative to a “state of being under stress.” Thereafter, a correlation between the calculated evaluation value and a lens surface shape is calculated as an index characteristic in a lens-surface-shape determining step. Thereafter, a lens surface shape of a suitable spectacle lens in the index is determined based on the index characteristic, and the lens surface shape is fed back as a shape of a to-be-evaluated lens of the evaluation-value calculating step.
