摘要： The invention is directed to a colored contact lens designed for enhancing a wearer's eye color while maintaining the wearer's eyes natural appearance. A colored contact lens of the invention comprises a colored central zone which includes a 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.

摘要： The invention provides a method for producing colored contact lenses with relatively high quality color images. The method of the invention comprises the steps of: (a) obtaining a water-based ink, the ink having a viscosity of greater than (100) centipoise (cps), and the ink comprising water, at least one colorant, a water-soluble binder polymer having ethylenically unsaturated groups, an initiator, and a surfactant, wherein the surfactant is present in the ink in an amount sufficient to provide the ink a dynamic surface tension of less than 40 mN/m at surface age of 1 second; (b) applying the ink, by using pad transfer printing technique, to at least a portion of at least one of molding surfaces of a lens mold to form a colored coat; (c) actinically or thermally curing the ink printed on the mold to form a colored film, wherein the printed ink is cured to an extent so that no noticeable color smearing is observed by examination with naked eyes; (d) dispensing a lens-forming material into the lens-forming cavity of the mold; and (e) actinically or thermally curing the lens-forming material within the lens-forming cavity to form a colored contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens, wherein the colored film becomes part of one of the anterior and posterior surface of the colored contact lens and has a good adhesion to the lens.
