摘要:
A set of eyeglass lens semifinished products is provided and is composed of at least three series of eyeglass lens semifinished products having spherical or rotationally symmetric aspherical front surfaces. The series of eyeglass lens semifinished products differ in pairs in the base material of the series. Each of the series includes at least three types of eyeglass lens semifinished products which differ in pairs and the front surface shapes. The front surface shapes of the at least three types are identical on a central partial surface within the actual surface refractive power range of the front surface of the series in relation to a standard index of refraction of 1.53 between 3.2 D and 6.7 D.
