The pattern is made up of a first portion having a first shade, a second portion having a second shade different from the first shade, and a third portion having a shade different from the second portion and either the same or different from the first portion. A first uneven border differentiates the first and second portions, and a second uneven border differentiates the second and third portions, however, said portions may overlap. The lens is capable of changing the appearance of the iris of the person wearing the lens.

L'invention concerne une lentille de contact colorée (10) dont la partie pupille (20) n'est pas opaque, cette lentille présentant également une partie iris (22) entourant cette partie pupille, et un motif coloré, opaque, et irrégulier qui recouvre cette partie iris, un observateur ordinaire étant incapable de distinguer ce motif. Ce motif est constitué d'une première partie d'une première intensité, d'une deuxième partie d'une deuxième intensité, différente de la première, et d'une troisième partie dont l'intensité est différente de la deuxième intensité, mais identique à la première intensité ou différente de celle-ci. Un premier bord irrégulier permet de différencier les première et seconde parties, bien que celles-ci puissent se chevaucher. La lentille de cette invention est capable de changer l'apparence de l'iris de la personne portant cette lentille.
