Abstract

A method for manufacturing an ophthalmic lens includes molding the lens (1) between a first mold portion (6A) and a second mold portion (6B) with the first entry surface (4A) formed by making in the lens a molded cavity by means of a stud (6C) secured to the second mold portion (6B), and that the light guide (4) is temporarily secured to the stud (6C) prior to molding. The second entry surface (4B) is formed by making in the lens a molded cavity by means of a mold insert (7) temporarily secured to the light guide (4) prior to molding, the first mold portion (6A) being placed above said insert (7).
