A tinted or colored contact lens has a pupil section, an iris section having an area and circumferentially surrounding the pupil section, and a colorant component extending across a major portion of the area of the iris section. The colorant component provides a color to the iris section and at least one additional benefit to the contact lens. For example, the colorant component may enhance the natural appearance of the iris section when the contact lens is in an eye. Alternatively or in addition, the colorant component may enhance the perception of depth in the iris section by an ordinary viewer. Still further, the colorant component may provide a darkened-image within an outer portion of the iris section. |
