Abstract
Abstract A non-optical cosmetic device for changing the apparent color of the eye. The colored cosmetic device has a central visual aperture and surrounds the pupil of the eye. Fluorescent pigments are added to the final monomer before being polymerized to form the soft hydrophilic 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
67 words
A non-optical cosmetic device for changing the apparent color of the eye substantially the size of the cornea having an open central visual aperture substantially the size of the pupil of the eye the convex surface being tapered to form a thin inner edge surrounding the central pupil aperture and a colored fluorescent pigment within the device emits light of a preselected color when illuminated by daylight.
Claim 2
Dependent Claim
67 words
A non-optical cosmetic device for changing the apparent color of the eye substantially the size of the cornea having an open central visual aperture substantially the size of the pupil of the eye the convex surface being tapered to form a thin inner edge surrounding the central pupil aperture and a colored fluorescent pigment within the device emits light of a preselected color when illuminated by daylight.
Claim 3
Dependent Claim
28 words
The subject matter set forth in claim 1 wherein the fluorescent pigment is added to the liquid monomer before the liquid monomer is polymerized to form the device.
Claim 4
Dependent Claim
17 words
The subject matter set forth in claim 1 wherein the device is made from a translucent material.
Claim 5
Dependent Claim
19 words
