DIFFRACTIVE ARTIFICIAL OPHTHALMIC LENS WITH OPTIMISED APODIZATION AND METHOD FOR THE PRODUCTION OF SUCH ARTIFICIAL OPHTHALMIC LENS

The object of the invention relates to an artificial ophthalmic lens (20) that contains an anterior optical surface (21) and a posterior optical surface (22), where the anterior optical surface (21) and the posterior optical surface (22) have a common optical axis (23), and at least one of the anter...

Beschreibung
Zusammenfassung:	The object of the invention relates to an artificial ophthalmic lens (20) that contains an anterior optical surface (21) and a posterior optical surface (22), where the anterior optical surface (21) and the posterior optical surface (22) have a common optical axis (23), and at least one of the anterior optical surface (21) and the posterior optical surface (22) is a multifocal optics (24) that atleast partly has a multifocal optical diffractive profile (25). A cross apodized profile part (25') is formed on the diffractive profile (25), in other words phase shifting elements (27) are providedon the diffractive profile (25) that alternately form the elements of a decreasingly apodized series (40) and an increasingly (reversed) apodized series (41) in such a way that the decreasing and increasing elements of the two series (40, 41) form envelope curves that meet at a common intersection point (45). The object of the invention also relates to a method for the production of such an artificial ophthalmic lens (20).
