Abstract

The invention is directed to a colored contact lens designed for making a wearer's eyes to appear larger and more defined and with more shine, while remaining natural by blending seamlessly with the eye. A colored contact lens, comprising a first print of a first color and a second print of a second color, wherein the first print is an annular ring of gradient dot matrix, wherein the second print is an annular ring of speckle pattern, wherein the annular ring of speckle pattern comprises clusters of regular or irregular shapes distributed annularly, wherein the regular or irregular shapes consists of a large number of circular dots, wherein the annular ring of speckle pattern has non-smooth inner and outer borders, wherein the second print is located on the inside of the first print, wherein 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

1 . A colored contact lens, comprising a first print of a first color and a second print of a second color, wherein the first print is an annular ring of gradient dot matrix, wherein the second print is an annular ring of speckle pattern, wherein an exterior peripheral edge of the first print has a diameter from about 12.5 mm to about 15 mm and the width of the first print is from about 0.8 mm to about 3.5 mm, wherein the annular ring of speckle pattern comprises clusters of regular or irregular shapes distributed annularly, wherein the regular or irregular shapes consists of a large number of circular dots, wherein the annular ring of speckle pattern has non-smooth inner and outer borders, wherein the second print is located on the inside of the first print, wherein 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.

2 . The colored contact lens of claim 1 , wherein the first print has a color selected from a group consisting of black, gray, brown and blue.

3 . The colored contact lens of claim 1 , wherein the second print has a color selected from a group consisting of black, gray, brown and blue.

4 . The colored contact lens of claim 1 , wherein an exterior peripheral edge of the first print has a diameter from about 12.5 mm to about 15 mm and the width of the first print is from about 0.8 mm to about 3.5 mm.

5 . The colored contact lens of claim 4 , wherein the first print has a width of from about 2.0 mm to about 3.0 mm.

6 . The colored contact lens of claim 1 , wherein the width of the speckle annular ring pattern is about 30-90% of the width of the annular ring of gradient dot matrix.

7 . The colored contact lens of claim 1 , wherein the speckle annular ring 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 . The colored contact lens of claim 1 , further comprising a third print of a third color, wherein the third print is a first tulip flower ring pattern has a shape comprising two elements, the first element is a vermicular shape having a thicker center and thinner at a first end and a second end; the second element is a mirror image of the first element, the first end of the first element and the first end of the second element are converged to touch each other and the second end of the first element and the second end of the second element are diverged, wherein the tulip flower is repeated annularly around to form a ring with the converged points pointing inwards, wherein the first color, the second color and the third color are different or the same, wherein the first print, the second print and the third print are concentric with the center of contact lens.

9 . The colored contact lens of claim 8 , wherein the third print has a color selected from a group consisting of blue, gray, black, brown, blue, turquoise, violet, blue-violet, aqua, orange, yellow, hazel and green.

10 . The colored contact lens of claim 8 , further comprising a fourth print of a fourth color, wherein the fourth print is a second tulip flower ring pattern has a shape comprising two elements, the first element is a vermicular shape having a thicker center and thinner at a first end and a second end; the second element is a mirror image of the first element, the first end of the first element and the first end of the second element are converged to touch each other and the second end of the first element and the second end of the second element are diverged, wherein the tulip flower is repeated annularly around to form a ring with the converged points pointing outwards, wherein the first tulip flower ring pattern annular ring and second tulip flower ring pattern have an identical outer diameter and the second tulip flower ring pattern has a same or a smaller inner diameter than that of the first tulip flower ring pattern, wherein the first color, the second color, the third color and the fourth color are different or the same, wherein the first print, the second print, the third print and the fourth print are concentric with the center of contact lens.

11 . The colored contact lens of claim 10 , wherein the fourth print has a color selected from a group consisting of blue, gray, black, brown, blue, turquoise, violet, blue-violet, aqua, orange, yellow, hazel and green.

12 . The colored contact lens of claim 9 , wherein the second tulip flower ring pattern has a smaller inner diameter than that of the first tulip flower ring pattern.

13 . A method for making a colored contact lens, comprising the steps of:
(a) providing a preformed contact lens; and (b) applying a first print pattern of opaque colored dots of a first color onto a surface of at least one of the anterior and posterior surfaces of the contact lens, wherein the first print is an annular ring of gradient dot matrix, (c) applying a second print pattern of opaque colored dot of a second color onto the surface of the contact lens, wherein the second print is an annular ring of speckle pattern, wherein the annular ring of speckle pattern comprises clusters of regular or irregular shapes distributed annularly, wherein the regular or irregular shapes consists of a large number of circular dots, wherein the annular ring of speckle pattern has non-smooth inner and outer borders, wherein the second print is located on the inside of the first print, wherein 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.

14 . 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, a second print pattern of opaque colored dot of a second color to onto at least one of molding surfaces of a lens mold, wherein the second print is an annular ring of speckle pattern, wherein the annular ring of speckle pattern comprises clusters of regular or irregular shapes distributed annularly, wherein the regular or irregular shapes consists of a large number of circular dots, wherein the annular ring of speckle pattern has non-smooth inner and outer borders, and (c) applying, by using pad-transfer or inkjet printing technique, a first print pattern of opaque colored dots of a first color onto the surface of the mold, wherein the first print is an annular ring of gradient dot matrix, wherein the second print is located on the inside of the first print, wherein 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.
