Abstract
A process for manufacturing an ophthalmic lens () having at least one optical function, includes: a step () of additively manufacturing the ophthalmic lens () by depositing a plurality of preset volume elements of at least one material having a preset refractive index in order to form a target geometric envelope; a step of determining an actual geometric envelope at least once during the implementation of the additive manufacturing step (); and a step of triggering a corrective action if there is in a zone a discrepancy larger than a preset threshold between the target geometric envelope and the actual geometric envelope.
