Abstract:
The invention relates to a multifocal lens (1), in particular an intraocular lens or contact lens, having a refractive focus (Fr) 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 (F1;1) of the first diffractive structure (6) coincides with a first order focus (F2,1) of the second diffractive structure (7). The invention further relates to a method for producing such a multifocal lens (1).
