## CPC

- G02C 7/046: {Contact lenses having an iris pattern}
- G02C: SPECTACLES; SUNGLASSES OR GOGGLES INSOFAR AS THEY HAVE THE SAME FEATURES AS SPECTACLES; CONTACT LENSES (trial frames for testing the eyes A61B3/04; goggles or eyeshields not having the same features as spectacles A61F9/00)

## Abstract

A contact lens, comprising a preprint of a first shade and a main print of a second shade, wherein the preprint consisting of a first band of gradient dot matrix, wherein the main print consisting of a second band of evenly spaced circular voids, wherein the second band surrounds the starburst pattern, wherein the first band and the second band have a substantially identical outer diameter and the first band has a smaller inside diameter than the second band, wherein the first shade and the second shade are different, wherein the gradient dot matrix is characterized by dot coverage increases in a radial direction from the center too the peripheral edge or a position near the peripheral edge of the substantially-circular pattern.

## Claims

### Claim 1

A colored contact lens, comprising:
a non-opaque pupil section,
a generally annular iris section surrounding the pupil section, the iris section having a colored, printed, opaque, intermittent pattern, said pattern comprising:
a) an annular pattern of a color having a first shade, wherein the annular pattern is composed of colored dots which are opaque, and the annular pattern has a substantially even outer peripheral edge and a substantially even inner peripheral edge, and the outer peripheral edge can have a diameter of from about 13.5 mm to about 12.5 mm and the inner peripheral edge can have a diameter of from about 5 mm to about 7 mm, and
b) at least two other colored patterns extending across a portion of the iris section selected from a group of patterns consisting of outermost starburst pattern, outer starburst pattern and inner starburst pattern, wherein the outermost starburst pattern comprising dots of a second shade, the outer starburst pattern comprising dots of a third shade and inner starburst pattern comprising dots of a fourth shade, wherein the fourth shade is different from the third shade and either the same or different from the second shade,
wherein sizes of the colored dots and/or amounts of space between the colored dots of the annular colored pattern are varied in a radially-controlled manner so that local colored dot coverage increases in a radial direction from the inner perimeter of the annular iris section to the outer perimeter of the annular iris section, wherein annular colored pattern has a size sufficient to cover the most or the whole iris of an eye to make changes to the color of the eye or enhance the color of the eye, and wherein the combination of the substantially-annular colored pattern and the other color patterns to change the apparent color of the iris of the wearer of the lens.

### Claim 2 (depends on 1)

The colored contact lens of claim 1, the colored, printed, opaque, intermittent pattern overlying at least 30% of the iris section.

### Claim 3 (depends on 2)

The colored contact lens of claim 2, comprising the outermost starburst pattern comprising dots of the second shade and the outer starburst pattern, wherein the outer starburst pattern comprising dots of the third shade and overlaying at least a portion of the outer most starburst pattern.

### Claim 4 (depends on 2)

The colored contact lens of claim 2, comprising the outermost starburst pattern comprising dots of the second shade and the inner starburst pattern, wherein the inner starburst pattern comprising dots of the fourth shade and overlaying at least a portion of the outer most starburst pattern.

### Claim 5 (depends on 2)

The colored contact lens of claim 2, comprising the outer starburst pattern comprising dots of the third shade and the inner starburst pattern, wherein the inner starburst pattern comprising dots of the fourth shade and overlaying at least a portion of the outer starburst pattern.

### Claim 6 (depends on 5)

The colored contact lens of claim 5, comprising a) the outermost starburst pattern comprising dots of the second shade, b) the outer starburst pattern, wherein the outer starburst pattern comprising dots of the third shade and overlaying at least a portion of the outer most starburst pattern and c) the inner starburst pattern, wherein the inner starburst pattern comprising dots of the fourth shade and overlaying at least a portion of the outer starburst pattern and a portion of the outer most starburst pattern.

### Claim 7 (depends on 1)

The colored contact lens of claim 1, wherein the dots of the substantially-circular colored pattern and dots of the outermost starburst pattern, dots of the outer starburst pattern and the dots of the inner starburst pattern are at least one of round, square, hexagonal or elongated dots.

### Claim 8 (depends on 2)

The colored contact lens of claim 2, wherein the shade of a substantially annular pattern is at least one of black, dark brown, dark blue, dark green, and dark gray.

### Claim 9 (depends on 2)

The colored contact lens of claim 2, wherein the shade of the outermost starburst portion is at least one of black, gray, dark brown, and dark blue.

### Claim 10 (depends on 9)

The colored contact lens of claim 9, wherein the shade of the outer starburst portion is at least one of blue, gray brown, light blue, turquoise, violet, blue violet, aqua, yellow, and green.

### Claim 11 (depends on 10)

The colored contact lens of claim 10, wherein t the shade of the inner starburst portion is at least one of hazel, yellow, yellow green, brown, yellow brown, gold, and orange.

### Claim 12 (depends on 1)

The colored contact lens of claim 1, wherein the annular pattern is composed of colored dots having at least one pearlescent pigment in an amount sufficient to provide the iris section of the contact lens a desired amount of pearlescence, luster, shine or combination thereof.

### Claim 13 (depends on 2)

The colored contact lens of claim 2, wherein all of the colored dots are similar in shape.

### Claim 14 (depends on 13)

The colored contact lens of claim 13, wherein all of the colored dots are substantially circular.

### Claim 15 (depends on 2)

The colored contact lens of claim 2, further comprises a dark limbal ring located near the peripheral edge of the annular colored pattern, wherein the limbal ring is comprised of a dark colorant and has a substantially even exterior peripheral edge and a jagged or substantially-even interior peripheral edge.

### Claim 16 (depends on 15)

The colored contact lens of claim 15, wherein the limbal ring overlaps to some degrees with the annular color pattern.

### Claim 17 (depends on 2)

The colored contact lens of claim 2, wherein both the sizes of the dots and the amounts of space between two dots are varied in a way that the size of each dot increases gradually whereas the amount of space between dots decreases gradually in the radial direction.

### Claim 18 (depends on 2)

The colored contact lens of claim 2, wherein the size of each dot is substantially constant whereas the amount of space between dots decreases gradually in the radial direction.
