Beschreibung
Zusammenfassung:	The invention relates to a hybrid diffractive/refractive multifocal ophthalmic lens which can be used as an intraocular lens or contact lens and which is produced on the basis of a refractive lens in which the thickness of one of the faces is increased using a function constructed from an aperiodic but ordered step function by means of an iterative method. Consequently, chromatic aberration is reduced and the depth of field of the lens is increased and, since no notched surfaces are required, the lens can be used as a contact lens.
