A tinted or colored contact lens (30) has a pupil section (22), an iris section (24) having an area and circumferentially surrounding the pupil section (22), and a colorant component (32) extending across a major portion of the area of the iris section (24). The colorant component (32) provides a color to the iris section (24) and at least one additional benefit to the contact lens (30). For example, the colorant component (32) may enhance the natural appearance of the iris section (24) when the contact lens (30) is in an eye. Alternatively or in addition, the colorant component (32) may enhance the perception of depth in the iris section (24) by an ordinary viewer. Still further, the colorant component (32) may provide a darkened-image (74) within an outer portion of the iris section (23). |
