Patent ID: 7563153

Claim:
A method of preparing eyeglass lenses for mounting in the frame selected by the wearer, taking account of stored mounting parameters associated with the morphology of the wearer and with the shape of the frame, the method comprising the following steps: a “centering” first step during which the optical frame of reference of the lens is acquired and a blocking accessory is appropriately positioned in the optical frame of reference of the lens; and a second step of shaping the lens to have a desired outline in a frame of reference associated with the blocking accessory and thus the optical frame of reference of the lens, with account being taken of the mounting parameters, wherein the blocking accessory is fitted with an electronic identification element bearing an identification code, and said identification code of the electronic element is read initially during a first read during the centering step to associate the code in memory with the mounting parameters of the lens that is receiving the blocking accessory and with an indication as to whether the lens in question corresponds to the right eye or the left eye of the wearer, and then during a second read during the shaping step in order to recover the mounting parameters and said indication associated with the identification code as read and thus with the lens attached to the blocking accessory.
