Abstract

The invention is directed to a colored contact lens designed for making a wearer's eyes to appear larger, bolder, and enhanced color while giving the wearers eyes a very natural appearance. A colored contact lens of the invention comprising a first print of a first color and a second print of a second color, wherein the first print consisting of an annular ring of gradient dot matrix, wherein the second print comprises a limbal ring and an outer starburst pattern, wherein the limbal ring surrounds the outer starburst pattern, wherein the annular ring and the limbal ring have a substantially identical outer diameter and the annular ring has a larger inside diameter than the limbal ring, the first color and the second color are different or the same, wherein the first print and the second print are concentric with the center of contact lens.

First claim

What is claimed is:

1. A colored contact lens, comprising
a limbal ring pattern color print, wherein the limbal ring pattern with evenly spaced circular voids;
an inner starburst pattern color print, wherein the inner starburst pattern is located generally on the inside of limbal ring pattern,
wherein the limbal ring pattern color print and the inner starburst pattern color print are concentric with the center of contact lens.

2. The colored contact lens of claim 1 , wherein the interior peripheral edge of the limbal ring is at a diameter of about 5 mm to about 12 mm from the lens' geometric center.

3. The colored contact lens of claim 1 , wherein the limbal ring has a width of from about 0.5 to about 2.5 mm.

4. The colored contact lens of claim 3 , wherein the limbal ring has a width of from about 0.8 mm to about 1.25 mm.

5. The colored contact lens of claim 1 , wherein the limbal ring pattern print has a color selected from a group consisting of black, dark-gray, dark-brown and dark-blue.

6. The colored contact lens of claim 1 , wherein the inner starburst pattern print has a color selected from a group consisting of hazel, yellow, yellow-green, brown, yellow-brown, gold and orange.

7. The colored contact lens of claim 1 , wherein the inner starburst pattern comprising pearlescently colored, wherein the pearlescently colored element comprises at least one pearlescent pigment in an amount sufficient to provide to the inner starburst pattern of the contact lens a desirable amount of pearlescent to impart a shine appearance to a wearer's eye.

8. A method for making a colored contact lens, comprising the steps of:
(a) providing a preformed contact lens; and
(b) applying a limbal ring print pattern of opaque colored dots onto a surface of at least one of the anterior and posterior surfaces of the contact lens,
wherein the limbal ring print pattern with evenly spaced circular voids,
(c) applying an inner starburst print pattern of opaque colored dot onto the surface of the contact lens, wherein the inner starburst print pattern is located generally on the inside of limbal ring pattern, wherein the limbal ring print and the inner starburst print are concentric with the center of contact lens.

9. The method of claim 8 , wherein the steps (b) and (c) of applying are carried out according to a pad-transfer or inkjet printing process.

10. The method of claim 8 , wherein the method further comprises forming a clear coat covering at least part of the surface of the contact lens.

11. A method for making a colored contact lens, comprising the steps of:
(a) providing a mold including a first mold half having a first molding surface defining the anterior surface of a contact lens and a second mold half having a second molding surface defining the posterior surface of the contact lens, wherein the first and second mold halves are configured to receive each other such that a contact lens forming cavity is formed between the first and second molding surfaces;
(b) applying, by using pad-transfer or inkjet printing technique, an inner starburst print pattern of opaque colored dot onto at least one of molding surfaces of a lens mold, wherein the inner starburst pattern is located generally on the inside of limbal ring pattern,
(c) applying, by using pad-transfer or inkjet printing technique, a limbal ring print pattern of opaque colored dots onto the surface of the mold,

wherein the limbal ring print and the inner starburst print are concentric with the center of contact lens.

12. The method of claim 11 , wherein a transferable clear coating is applied onto the molding surface of the mold before the step (b).
