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

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.

Method of manufacturing a lens for providing an optical display

The present invention relates to a display system for stereoscopic viewing, the system comprising a binocular viewing device, information content, and a display source. The display system is remarkable in that it further comprises electronic components for implementing pieces of software for optimizing the binocular viewing device, the information content, and the display source, said pieces of optimization software together forming a loop for managing various parameters. The wearer of said device can thus view the information content via the binocular viewing device under conditions that are best adapted to the wearer's physiology.

Display system for stereoscopic viewing implementing software for optimization of the system

The invention provides an adjustment method for adjusting a binocular display, the display comprising for each eye of the wearer, an optical imager for shaping light beams corresponding to an image emitted by a beam generator device and for directing them towards each of the wearer's eyes so as to enable information content contained in a virtual image to be viewed, the display being associated with a pair of eyeglasses having two lenses supported by a frame. According to the invention, the method consists in moving at least one said lens (A,B) relative to said frame () with three degrees of freedom, in order to obtain superposition of the two virtual images, each said imager being contained in said lens (A,B) of said pair of eyeglasses.

Method of adjusting a display of binocular type comprising a pair of spectacles and display for the implementation of this method

A light pipe is provided for transmitting light signals from one of its ends to its other end facing toward the eye of a user for viewing a virtual image. The light pipe includes a diffractive component formed directly in the inlet surface. The diffractive component is an element satisfying the equation of an aspherical component of revolution of the 'kinoform' type, where the diffractive component of the pipe has power situated in a range D (Thresh, X) defined by D(Thresh, X)=D(Thresh) INTERSECTION D(X).

Optical pipe intended for producing an electronic display arrangement

The invention relates to a binocular device for displaying information, the device comprising a support for placing on the nose and supporting a right display element and a left display element each designed to be placed in front of an eye and each comprising a light guide for receiving a beam of light rays emitted by a beam generator device towards an inlet face and for propagating the beam to an outlet face where the beam is directed towards the corresponding eye, the binocular device having an arrangement for adjusting the pupillary distance by moving at least one of the light guides relative to said support so as to adjust the distance between the light guides. According to the invention, said light guides are disposed over a said support and are held by a strip disposed over the light guides and secured to said support by means of at least one spacer, at least one slack takeup means being interposed between said strip and said light guides.
