    Abstract: The process according to the invention is of the kind according to which an additive substance (11) is diffused in a controlled manner within a base substance (10) which, made up of at least one partially polymerised monomer capable of resulting in a homopolymer of refractive index N1, is in the state of a gel, the additive substance itself being made up of at least one monomer capable of producing a homopolymer of refractive index N2 which differs from N1. According to the invention the additive substance (11) chosen is a mixture of at least two monomers (A, B) and the composition of this mixture is varied with time. Application to the production of components made of synthetic substance of optical quality suited especially to the production of ophthalmic lenses.

    Abstract: This procedure is of the kind in which the absorption, by a base-polymer material, of an additive composition enclosing at least one monomer capable of leading to a polymer of different refractive index is ensured. … According to the invention, by choosing a swelling composition as the additive composition, a first preform (P1) is produced, with a first geometry (G1), from a polymer material at a rate of advance sufficient for it to be self-supporting, a confinement volume (14) is defined between this first preform and an abutment element having a second geometry (G2) corresponding to a greater volume, and it is brought into contact there with a quantity of swelling additive composition sufficient for the swelling, to which it is then subjected, to cause it to match, under stress, this second geometry (G2). … Application, especially, to the production of ophthalmic lenses. … …

    Abstract: Procedimiento de fabricación de una lente de corrección de la vista que tiene una cara anterior (1) y una cara posterior (2) y en la cual haces ópticos emitidos por un elemento óptico de un sistema de generación (7) de haces ópticos se introducen a través de una superficie de entrada (6a, 8a) y se dirigen hacia el ojo (4) del portador para permitir la visualización de un contenido de información (I), estando dicho inserto dispuesto en dicha lente cuando se moldea esta última en un molde que tiene una primera parte del molde (10A) destinada al moldeo de dicha cara anterior (1) y una segunda parte del molde (10B) destinada al moldeo de dicha cara posterior (2) y estando totalmente contenido en la lente (3); procedimiento caracterizado porque dichos haces ópticos son reflejados numerosas veces entre dos caras denominadas caras de reflexión entre su introducción y su salida de la lente (3), siendo dichas dos caras de reflexión (5a, 5b) caras de un inserto óptico (5) transparente constituido por una guía de luz; dicha superficie de entrada (6a) está formada por realización de una cavidad moldeada en la lente y de la cual ella es el fondo y dicha cavidad está moldeada por medio de una plataforma (10C) solidaria de la segunda parte del molde (10B) y dicho inserto (5) se fija de manera provisional a esta plataforma antes del moldeo.

    Abstract: The invention relates to a method of manufacturing a vision correction 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 are introduced via an entry surface and directed towards the eye of the wearer to enable information content to be viewed, said light beams being reflected a plurality of times between two “reflection” faces between being introduced into the lens and exiting therefrom, said two reflection faces being faces of a transparent optical insert constituted by a light guide. According to the invention, said insert is completely contained within the lens.
