A method for manufacturing a diffractive multi-focal ophthalmic lens capable of generating at least three focal points in an optical axis direction using a diffractive structure comprising a plurality of zones in a concentric circle form. A composite profile is generated by overlapping at least two starting profiles comprising a plurality of zones in a concentric circle form, and an adjusted profile is generated in which at least one of phase and amplitude is adjusted by employing a zone of the composite profile as a subject in order to set an intensity distribution in the optical axis direction and determine optical characteristics, to manufacture the diffractive multi-focal ophthalmic lens for which the adjusted profile is provided in at least a portion of the diffractive structure.
