The invention concerns a method of manufacturing a lens (1, 2) that has a front face and a rear face, and into which light beams emitted by an optical element of a light beam generator system (IB) are introduced via an entry surface (Si) and directed towards the eye of the wearer to enable information content to be viewed, by means of a transparent optical insert (IA, 2A, I) constituted by a light guide, said insert (I) being with a form substantially identical to the form of a final lens suitable for being positioned in a frame (3) of a support. According to the invention, the method comprises the following steps: manufacturing said insert (I) with a form smaller than the form of said final lens according to a proportional transformation, manufacturing a lens blank (LB) by association of plastic material forming said front face and said rear face with said insert (I) and cutting said lens blank (LB) around said insert (I) and with a distance from the edges of said insert which is around 1 mm for at least 50% of the periphery of said insert.
