Abstract
The method comprises the following steps: 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 then during a second read during the shaping step in order to recover the mounting parameters associated with the identification code as read and thus with the lens attached to the blocking accessory.
