It is understood that spherical, toric and polyfocal lenses, for use in the human eye, including bifocal contact lenses, having powers covering the ranges from about -20 to about +20 diopters can be advantageously prepared by methods A, and B, described supra.

The finish-grinding and polishing of blanks for toric lenses is usually carried out by means of tools which have a continuous or uninterrupted, toric surface complementary to the desired lens surface.

For machining toric lenses, the lens support 10 is releasably locked to an intermediate component 21, mounted concentrically thereto and holding the lens 20.

In order to produce toric eyeglass lenses, i.e., eyeglass lenses of astigmatic action, a plug is selected with a surface 9 characterized by a torus which corresponds to the desired correction value for the astigmatism.

When spherical or toric spectacle lenses are polished, it is less problematical, on account of the relatively simple shape of the surface to be polished, to find a suitable polishing tool of complementary configuration which can be guided over the surface with simple movement sequences which does not bring about any impermissible deformations.
