A method of controlling a head mounted see-through electro-optical device adapted to a wearer A method of controlling a head mounted electro-optical device adapted to a wearer, the method comprising: a wearer visual profile parameter providing step, during which the value of at least one wearer parameter related to the visual profile of the wearer is provided, an head mounted device function adapting step, during which the head mounted device function of the electro-optical device is adapted based on the value of the at least one wearer parameter.

Method of controlling a head mounted electro-optical device adapted to a wearer

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

Method of manufacturing an ophthalmic lens for providing an optical display

A method produces a spectacle lens that provides both ophthalmic vision and an additional type of vision. The method includes two consecutive steps consisting of calculating a rear surface and a front surface of the lens. The additional vision type corresponds to the perception of a light that is conveyed between the front and rear surfaces by an insert built into the lens. The rear surface of the glass is initially calculated to provide a correction of the additional vision type, and the front surface is calculated to correct the ophthalmic vision. The two surfaces of the glass therefore have complex shapes, which simultaneously reduce the optical aberration levels for both types of vision.

The invention concerns a method of manufacturing a lens () 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,A, 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 () 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.
