Procedure for the manufacture of a glass for glasses with spherical anterior side and progressive posterior side

摘要

Procedure for the manufacture of glasses lenses (1) with multifocal effect, characterized in that the glasses lenses (1) are manufactured from semi-finished products with spherical or aspherical convex anterior surfaces (2) with rotation symmetry with few different radii , so that the total adaptation of the dioptric effect necessary individually occurs with the rear surface (3) of the lens for glasses (1) configured as a progressive viewing surface, formulating a profile of requirements with respect to the lens for glasses (1 ), composed of dioptric theoretical effects, specifically spherical, astigmatic, prismatic, at different points distributed by the lens for glasses (1) or also throughout the surface, including the theoretical effect at the far and near reference points.
