Abstract
The invention is directed to a colored contact lens designed for enhancing a wearer's eye color while giving the wearer's eyes a very natural appearance. A colored contact lens of the invention comprises a colored central zone which includes a colored substantially-circular pattern composed of non-opaque colored dots. Sizes of the dots and/or amounts of space between the dots are varied in a radially-controlled manner so that local colored dot coverage increases in a radial direction from the center to the peripheral edge or a position near the peripheral edge of the substantially-circular pattern.
