Abstract

PROCEDE POUR ELABORER UNE SURFACE DE REFRACTION D'UNE LENTILLE OPHTALMIQUE A PUISSANCE PROGRESSIVEMENT VARIABLE, DANS LEQUEL ON DETERMINE, DANS UN SYSTEME DE REFERENCE DONNE, UNE FAMILLE DE SURFACES AYANT DES CARACTERISTIQUES OPTIQUES PREDETERMINEES. ON DETERMINE, DANS LE MEME SYSTEME DE REFERENCE, UNE DEUXIEME FAMILLE DE SURFACES S AYANT D'AUTRES CARACTERISTIQUES PREDETERMINEES, ON ASSOCIE CHAQUE SURFACE S DE LA PREMIERE FAMILLE A CHAQUE SURFACE S ET ON DETERMINE LEURS COURBES D'INTERSECTION C ET D, ON CHOISIT PARMI LES PAIRES DE SURFACES SS, CELLE DONT LES COURBES C ET D MENAGENT ENTRE ELLES UN COULOIR RESPECTIVEMENT D'AU MOINS 15 ET 18 MM DE LARGEUR DANS LES ZONES DE VISION INTERMEDIAIRE Z ET DE VISION DE PRES Z, ET ON RETIENT, POUR LA SURFACE DE REFRACTION S, LA PARTIE DE LA SURFACE S DE LA PAIRE CHOISIE, QUI SE TROUVE ENTRE LES COURBES C ET D, ET LA PARTIE DE LA SURFACE S DE LA PAIRE CHOISIE, QUI SE TROUVE A L'EXTERIEUR DES COURBES C ET D.
