Abstract

Cette invention concerne un lentille de contact colorée qui peut être retirée pendant que l'on identifie la position de ladite lentille lorsqu'une personne la porte, ceci du fait qu'une section d'identification possède une couleur différente de celle de l'iris. Cette invention se caractérise en ce que la lentille de contact comporte une section d'identification de forme annulaire sauf au niveau d'une partie correspondant à la pupille, en ce que ladite section d'identification possède une taille qui lui permet de recouvrir une partie au moins de sa partie correspondant à l'iris du porteur, et en ce qu'elle possède une couleur qui peut être identifiée comme une marque lorsque la section d'identification recouvre l'iris du porteur.
