Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
53 words
A contact lens which changes the apparent color of the eye upon which it is worn comprising: a circular transparent colored central area; a circular semi-transparent area surrounding said circular transparent colored central area; and said circular semi-transparent area including a transparent colored material having a plurality of light reflecting particles dispersed therein.
Claim 2
Dependent Claim
53 words
A contact lens which changes the apparent color of the eye upon which it is worn comprising: a circular transparent colored central area; a circular semi-transparent area surrounding said circular transparent colored central area; and said circular semi-transparent area including a transparent colored material having a plurality of light reflecting particles dispersed therein.
Claim 3
Dependent Claim
19 words
The contact lens of Claim 1 and further including: a circular clear transparent area surrounding said circular semi-transparent area.
Claim 4
Dependent Claim
42 words
The contact lens of Claim 1 wherein said circular transparent colored central area is substantially the size and shape of the pupil of the eye and said circular semi-transparent area is substantially the size and shape of the iris of the eye.
Claim 5
Dependent Claim
45 words
The contact lens of Claim 1 wherein said light reflecting particles are dispersed and spaced apart from one another, such that between about 10% to about 50% of the light entering said circular semi-transparent area is reflected from the lens by said light reflecting particles.
Claim 6
Dependent Claim
32 words
The contact lens of Claim 1 wherein said light reflecting particles are dispersed and spaced apart from one another, such that light is transmitted through the lens between said light reflecting particles.
Claim 7
Dependent Claim
33 words
The contact lens of Claim 1 wherein said light reflecting particles are dispersed and spaced from one another and comprise between about 0.1% to about 5% by weight of the total lens weight.
Claim 8
Independent Claim
80 words
A method of making a cosmetic contact lens blank comprising the steps of: forming an open ended cylinder having an inside diameter approximately equal to the diameter of the desired lens pupil and an outside diameter approximately equal to the diameter of the desired lens iris from a mixture of a transparent monomer, a transparent colorant and light reflecting particles; filling the cylinder with a mixture of a transparent monomer and a transparent colorant; and cutting the cylinder into discs.
Claim 9
Independent Claim
80 words
A method of making a cosmetic contact lens blank comprising the steps of: forming an open ended cylinder having an inside diameter approximately equal to the diameter of the desired lens pupil and an outside diameter approximately equal to the diameter of the desired lens iris from a mixture of a transparent monomer, a transparent colorant and light reflecting particles; filling the cylinder with a mixture of a transparent monomer and a transparent colorant; and cutting the cylinder into discs.
Claim 10
Dependent Claim
16 words
The method of Claim 7 and further including: casting a transparent monomer layer around the cylinder.
Claim 11
Dependent Claim
11 words
The method of Claim 7 wherein the monomer is hydroxyethyl methacrylate.
Claim 12
Dependent Claim
15 words
The method of Claim 7 wherein the colorant is F.D. and C green Number 6.
Claim 13
Dependent Claim
15 words
The method of Claim 7 wherein the light reflecting particles are finely ground oyster shells.
Claim 14
Dependent Claim
14 words
The method of Claim 7 and further including: adding antimicrobial agents to the monomer.
Claim 15
Independent Claim
54 words
A method of making a cosmetic contact lens blank comprising the steps of: forming a transparent colored cylindrical rod from a mixture of a monomer and colorant; casting a semi-transparent cylinder around the rod, the cylinder formed from a mixture of a monomer, colorant and light reflecting particles; and cutting the cylinder into discs.
Claim 16
Independent Claim
54 words
A method of making a cosmetic contact lens blank comprising the steps of: forming a transparent colored cylindrical rod from a mixture of a monomer and colorant; casting a semi-transparent cylinder around the rod, the cylinder formed from a mixture of a monomer, colorant and light reflecting particles; and cutting the cylinder into discs.
Claim 17
Dependent Claim
16 words
The method of Claim 13 and further including: casting a monomer layer around the semi-transparent cylinder.
Claim 18
Dependent Claim
11 words
The method of Claim 13 wherein the monomer is hydroxethyl methacrylate.
Claim 19
Dependent Claim
15 words
The method of Claim 13 wherein the light reflecting particles are finely ground oyster shells.
Claim 20
Dependent Claim
14 words
The method of Claim 13 and further including: adding antimicrobial agents to the monomer.
