PROBLEM TO BE SOLVED: To provide an evaluation method for a spectacle lens by an induced activity of a cerebrum visual sense field or the like that objectively evaluates a spectacle lens applicable to a user by measuring a cerebral activity, and a design method for a spectacle lens using the evaluation method.SOLUTION: A user to be examined puts on a lens to be evaluated, and views a visual sense stimulation object for inducing an activity of at least one of a specific region of the visual sense field of the cerebrum and a specific region of a retina visual sense cell through the lens to be evaluated. An induced activity (induced activity of the cerebrum visual sense field or the like) of at least one of the specific regions of the visual sense field of the cerebrum and retina visual sense cell when the visual sense stimulation object is viewed through the lens to be evaluated is measured by an electroencephalograph or magnetoencephalograph, and the spectacle lens is evaluated based upon the time (latent time) from visual sense stimulation until change thereof, and the magnitude (amplitude) of the activity.
