Abstract
Abstract A daylight fluorescent cosmetic device for changing the apparent color of the eye. Fluorescent and nonfluorescent pigments are added to the monomer before being polymerized to form the hydrophilic device material. Daylight illumination activates the fluorescent pigments which radiate light of the desired color. The colored fluorescent light radiated from the cosmetic device changes the apparent color of the eye.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
68 words
A fluorescent cosmetic device for changing the apparent color of the eye substantially the size and shape of the cornea and a daylight fluorescent pigment dispersed within the device is composed of a fluorescent dye in a transparent organic amorphous resin particle capable of fluorescing light of a specific color under visible light, the fluorescent color being visible under daylight conditions changes the apparent color of the eye.
Claim 2
Dependent Claim
68 words
A fluorescent cosmetic device for changing the apparent color of the eye substantially the size and shape of the cornea and a daylight fluorescent pigment dispersed within the device is composed of a fluorescent dye in a transparent organic amorphous resin particle capable of fluorescing light of a specific color under visible light, the fluorescent color being visible under daylight conditions changes the apparent color of the eye.
Claim 3
Dependent Claim
84 words
A fluorescent cosmetic device for changing the apparent color of the eye substantially the size and shape of the cornea and a daylight fluorescent pigment dispersed within the device composed of a fluorescent dye in solid state solution in a transparent organic amorphous resin particle capable of fluorescing and radiating light of a specific color in the solid state under visible light at the blue end of the spectrum, the fluorescent color being visible under daylight conditions changes the apparent color of the eye.
Claim 4
Dependent Claim
84 words
A fluorescent cosmetic device for changing the apparent color of the eye substantially the size and shape of the cornea and a daylight fluorescent pigment dispersed within the device composed of a fluorescent dye in solid state solution in a transparent organic amorphous resin particle capable of fluorescing and radiating light of a specific color in the solid state under visible light at the blue end of the spectrum, the fluorescent color being visible under daylight conditions changes the apparent color of the eye.
Claim 5
Dependent Claim
19 words
The subject matter set forth in claim 2 wherein two or more colorants are added to the device material.
Claim 6
Dependent Claim
16 words
The subject matter set forth in claim 2 wherein the device has a negative refractive power.
Claim 7
Dependent Claim
16 words
The subject matter set forth in claim 2 wherein the device has a positive refractive power.
Claim 8
Dependent Claim
15 words
The subject matter set forth in claim 2 wherein the device has no refractive power.
Claim 9
Dependent Claim
92 words
A fluorescent cosmetic device for changing the apparent color of the eye substantially the size and shape of the cornea and dispersed within the device a daylight fluorescent pigment composed of a fluorescent dye in solid state solution in a transparent organic amorphous resin particle of a size less than 44 microns and capable of fluorescing and radiating light of a specific color in the solid state under visible light at the blue end of the spectrum, the fluorescent color visible under daylight conditions imparts an apparent color change to the eye.
Claim 10
Dependent Claim
92 words
A fluorescent cosmetic device for changing the apparent color of the eye substantially the size and shape of the cornea and dispersed within the device a daylight fluorescent pigment composed of a fluorescent dye in solid state solution in a transparent organic amorphous resin particle of a size less than 44 microns and capable of fluorescing and radiating light of a specific color in the solid state under visible light at the blue end of the spectrum, the fluorescent color visible under daylight conditions imparts an apparent color change to the eye.
Claim 11
Dependent Claim
28 words

Claim 12
Dependent Claim
19 words
The subject matter set forth in claim 7 wherein two or more colorants are added to the device material.
Claim 13
Dependent Claim
16 words
The subject matter set forth in claim 7 wherein the device has a negative refractive power.
Claim 14
Dependent Claim
16 words
The subject matter set forth in claim 7 wherein the device has a positive refractive power.
Claim 15
Dependent Claim
15 words
The subject matter set forth in claim 7 wherein the device has no refractive power.
