Abstract:
The invention relates to a process for manufacturing an ophthalmic lens equipped with an insert (1), by means of a mold, comprising: —a step of molding a puck (3) comprising two faces (3A, 3B) and said insert (1) positioned between said faces; and —a step of machining at least one of said faces (3A, 3B) of said puck in order to form one of the front or back faces of said ophthalmic lens, the insert (1) being positioned relative to one portion of the mold before said molding step, According to the invention, an element associated with the insert or an imprint of this element left in the puck after the element has been removed comprises at least one of its portions providing a positional reference relative to said insert (1) in the machining step.
