A method for producing a spectacle lens having in particular a diffractive microstructure on at least one lens surface. To this end, a thin structural support layer is initially made available, which on a surface has a microstructure. A lens main body is then cast to the microstructure of the structural support layer.

Producing microstructured spectacle lenses by means of transfer layer

Device for blocking a spectacle lens blank that has a finished surface and a machining surface, situated opposite the finished surface, for machining in a machining device. The device includes a receiving component having a convex, planar or concave receiving surface for blocking the finished surface of the spectacle lens blank, wherein the receiving component has an essentially flat counter-surface that is arranged opposite the receiving surface, and wherein the normal of the counter-surface is inclined by 1&#xb0; to 10&#xb0; counter to the normal at the middle point of the receiving surface.
