CALCULATION MODULE AND COMPUTER IMPLEMENTED METHOD CONFIGURED TO SELECT A SEMI-FINISHED LENS BLANK

Abstract: calculation module comprising a memory and a processor. the calculation module is configured to select an adapted semi-finished lens blank among a plurality of semi-finished lens blanks for manufacturing an ophthalmic lens to be mounted in a frame of an eyewear. the eyewear is intended to be worn by a user. the calculation module is configured to determine a geometrical parameter value of the ophthalmic lens to be manufactured from a test semi-finished lens blank of the plurality, the geometrical parameter value of the ophthalmic lens depending on a base-curve of the test semi-finished lens blank, a refractive index of the test semi-finished lens blank, a prescription of the user and/or a characteristic parameter value of the frame. the calculation module is configured to select the adapted semi-finished lens blank based on the geometrical parameter value of the ophthalmic lens.
