description	Mandril de fijación de vacío para la retención de una pieza bruta de lente de gafas con una superficie delantera esférica, - con una superficie de apoyo esférica (A) adaptada a la forma de la superficie delantera, en el que - en la superficie de apoyo (A) están mecanizadas unas acanaladuras (Si), en las que se puede generar un vacío, y en el que - la superficie de apoyo (A) presenta un radio fijo (R), caracterizado por que - las acanaladuras (Si) están configuradas en forma de anillo. The requirements of the spectacles prescription, comprising spherical or astigmatic or prismatic effect and their distribution on the prescription surface of the spectacles lens are fulfilled. The rear surface of the spectacles lens is a multi-focal surface without point or axis symmetry. The convex spherical front surface of the lens is held, during shaping of the rear surface, on a matching concave spherical surface with circular grooves (Si) connected to a vacuum source. The rear surface of the spectacles lens is so formed that it evolves from the addition of a spherical or toric effect component with a bifocal or trifocal component. An individual optimisation of the dioptric values, e.g. sphere, astigmatism, prism, in all points on the surface of the spectacles lens facing the eye is provided.
