Abstract:
The invention relates to a multifocal lens ( 1 ), in particular an intraocular lens or contact lens, having a refractive focus (F r ) and a first and a second diffractive structure ( 6, 7 ) that at least partially overlap, said two diffractive structures ( 6, 7 ) being different. A first order focus (F 1;1 ) of the first diffractive structure ( 6 ) coincides with a first order focus (F 2,1 ) of the second diffractive structure ( 7 ). The invention further relates to a method for producing such a multifocal lens ( 1 ).

Claim (Index 11):
A method for producing a multifocal intraocular or contact lens according to  claim 1 , comprising the steps of:\n a) providing a moulded blank; b) calculating an overlapping structure from a first diffractive structure and a second diffractive structure, wherein the two diffractive structures are different, and wherein a first order focal point (F 1,1 ) of the first diffractive structure coincides with a first order focal point (F 2,1 ) of the second diffractive structure; c) incorporating the overlapping structure as a negative into the moulded blank; and d) producing the multifocal lens by bringing a lens material into contact with the moulded blank, wherein a refractive focal point (F r ) is also given to the lens material.
