摘要

The invention relates to a method for making spectacle lenses made withoutcuttingprefabricated the blanks, which are preferably made of plastic or silicaglass, with a frontand using a CNC machine remachined compared to lying back, which have incommon atleast a visual focal point, wherein on the finishing of the back of aprescription surfacebased on, refractive errors of a left and a right eye of a prescription owner,such acalculated net is that the machined back forms together with the front of afirstprescription lens and a second prescription lenses are made with these twolenses, andwhere the visual defects of the first lens in the left eye and the second lensto correctrefractive errors of the right eye of the prescription owner.
