A color modifying contact lens having an iris pattern having color elements that surround a non-opaque pupil section, wherein the pattern comprises three annular regions: an inner region, an intermediate region, and an outer region. The inner and outer regions each comprise a population of color elements effective to enhance or modify the wearer's eye color as observed by the ordinary viewer. The intermediate region has an area of between about 25-72%, and comprises a population of color elements that covers between about 5-30% of the area within the intermediate region. The color elements in the intermediate region form an array of substantially radial macro-striations that alternate between those having color elements and those without color elements.

Divulgation d'un verre de contact modifiant la couleur présentant un motif d'iris dont les éléments colorés entourent une section de pupille non opaque. Le motif comporte trois régions annulaires : une région intérieure, une région intermédiaire et une région extérieure. Les régions intérieure et extérieure comprennent chacune une population d'éléments colorés efficaces pour rehausser ou modifier la couleur des yeux du porteur, comme l'observateur ordinaire peut le constater. La région intermédiaire a une superficie d'environ 25-72 % et comporte une population d'éléments colorés qui couvre entre environ 5-30 % de la superficie de la région intermédiaire. Les éléments colorés dans la région intermédiaire forment un réseau de macro-stries essentiellement radiales qui alternent entre celles comportant des éléments colorés et celles qui en sont dépourvues.
