摘要:
Described is a single vision spectacle lens for spherical or astigmatic prescriptions. It is characteristic of the present invention that at least one surface is an atoroidal surface, and that along at least one line the refraction defect and the astigmatic defect for viewing angles of up to 40° are each smaller than ±0.15 dpt. In the case of an astigmatic prescription the deviation of the cylinder axis or axis orientation from the prescribed cylinder axis or axis orientation is smaller than 1°.
