A METHOD OF MANUFACTURING AN OPHTHALMIC LENS FOR PROVIDING AN OPTICAL DISPLAY

摘要

Method of manufacturing an ophthalmic lens (1), with a front face (1A) and a rear face (IB), and into which light beams emitted by an optical element of a light beam generator system are introduced and directed towards the eye of the wearer to enable information content to be viewed by means of a transparent light guide (4), constituted by two optical pieces, the first one (2A) placed on an entry surface (4A) of the rear face, the a second (2B) placed on an entry surface (4B) of the front face of the lens. - the first entry surface (4A) is formed by making a molded cavity in the lens by means of a stud (6C) secured to the second mold portion (6B), and that the light guide (4) is temporarily secured to said stud (6C) prior to molding; - the second entry surface (4B) is formed by making a molded cavity in the lens by means of a mold insert (7) temporarily secured to said light guide (4) prior to molding, said first mold portion (6A) being placed above said insert (7).
