A colored contact lens (10) having a non-opaque pupil section (20), an iris section (22) surrounding the pupil section (20), and a colored, opaque intermittent pattern made up of a plurality of elements located over the entire iris section (22) that leaves asubstantial portion within the interstices of the pattern non-opaque, the pattern covering an effective amount of the iris section (22) to change the apparent color of the iris, the pattern having a plurality of portions, each of the portions being a different shade from each other portion, each of the portions overlapping each other portion at a plurality of points, where at least one of the plurality of portions contains a design selected from the group consisting of uniform and non-uniform dots, islands of color, worms, starbursts, corkscrews, spokes, spikes, striations, radial stripes, zig-zags and streaks, thereby providing a lens (10) capable of changing the apparent color of the iris of a person wearing the lens (10) and imparting a very natural appearance.

L'invention concerne des lentilles de contact (10) colorées comprenant une partie pupille (20) non opaque, une partie iris (22) qui entoure ladite partie pupille (20), et un motif coloré, opaque par intermittence constitué de plusieurs éléments situés sur la totalité de la partie iris (22) qui laisse une partie substantielle dans les interstices du motif non opaque, ledit motif recouvrant une quantité efficace de la partie iris (22) de façon à modifier la couleur apparente de l'iris. Ce motif comprend plusieurs parties, chacune des parties présentant des nuances différentes, et se recouvrant au niveau de plusieurs points, au moins l'une des parties contenant un dessin sélectionné dans le groupe constitué par des points uniformes et non uniformes, des îlots de couleur, des vrilles, des étoiles rayonnantes, des spirales, des rayons, des pointes, des striures, des bandes radiales, des zig-zags et des stries, ce qui produit une lentille (10) capable de changer la couleur apparente de l'iris d'une personne portant lesdites lentilles (10), et conférant une apparence très naturelle.
