Title (EN) METHOD FOR DETERMINING AN OPTICAL SYSTEM, AND OPHTHALMIC LENS AND OPHTHALMIC FILTER DETERMINED BY SAID METHOD
(FR) PROCÉDÉ DE DÉTERMINATION D'UN SYSTÈME OPTIQUE, ET LENTILLE OPHTALMIQUE ET FILTRE OPHTALMIQUE DÉTERMINÉS PAR LEDIT PROCÉDÉ
Abstract:
(EN) The invention relates to a method for determining an optical system intended to equip a subject, said method comprising the steps of: - determining an index of sensitivity indicating, when the subject is placed in an environment including surfaces and/or borders forming globally a geometry of this environment; and landmarks associated with specific locations within the environment, how the subject relies on the global geometry and/or on the local landmarks of the environment to navigate within the environment; and - determining the optical system based on this index of sensitivity. The invention also relates to an ophthalmic lens and to an ophthalmic filter determined by such method.
(FR) L'invention concerne un procédé de détermination d'un système optique destiné à équiper un sujet, ledit procédé consistant : - à déterminer un indice de sensibilité indiquant, lorsqu'un sujet est placé dans un environnement comprenant des surfaces et/ou des bordures formant globalement une géométrie dudit environnement ; et des points de repère étant associés à des emplacements spécifiques dans l'environnement, la manière dont le sujet dépend de la géométrie globale et/ou des points de repère locaux de l'environnement pour naviguer dans l'environnement ; et - à déterminer le système optique en fonction dudit indice de sensibilité. L'invention concerne également une lentille ophtalmique et un filtre ophtalmique déterminés par ledit procédé.
