Abstract
A method of manufacturing an ophthalmic lens, includes the steps of providing, mounting and blocking a substrate (10) on a machining support unit (65), surfacing an upper face (12) of the substrate, edging a peripheral edge (13) of the substrate, wherein the machining support unit includes a surfacing member (40) and an edging member (30) which are separable, the surfacing member having a cavity (51) in which the edging member is located during the step of surfacing, the surfacing and edging members being configured so that the substrate is mounted and blocked on the machining support unit in a first predetermined position for the surfacing and the edging and, between the steps of surfacing and edging, the method further includes the step of withdrawing the surfacing member from the machining support unit by retaining the substrate on the edging member.
