Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 85 words
A cosmetic contact lens comprising an optically clear central visual region circumscribed by an area covering at least a portion of the iris, in which such circumscribing area comprises at least two superimposed figures, separated by at least some portion of the contact lens body, with at least the anterior figure having transparent, semi-transparent or open regions, which interact so as to effect a visual appearance, constituting the pattern, representing an apparent illusion of both of them even though the figures have not physically changed.
Claim 2
Dependent Claim 85 words
A cosmetic contact lens comprising an optically clear central visual region circumscribed by an area covering at least a portion of the iris, in which such circumscribing area comprises at least two superimposed figures, separated by at least some portion of the contact lens body, with at least the anterior figure having transparent, semi-transparent or open regions, which interact so as to effect a visual appearance, constituting the pattern, representing an apparent illusion of both of them even though the figures have not physically changed.
Claim 3
Dependent Claim 21 words
The cosmetic lens of claim 1 wherein the figures are physically solid and open regions or visually-formed solid and open regions.
Claim 4
Dependent Claim 18 words
The cosmetic lens of claim 1 wherein the figures are of the same or generally the same shape.
Claim 5
Dependent Claim 18 words
The cosmetic lens of claim 2 wherein the figures are of the same or generally the same shape.
Claim 6
Dependent Claim 17 words
The cosmetic lens of claim 1 wherein the figures have the same color or have different colors.
Claim 7
Dependent Claim 17 words
The cosmetic lens of claim 2 wherein the figures have the same color or have different colors.
Claim 8
Dependent Claim 65 words
A cosmetic contact lens which contains an iris region which provides for a moir',acu/e/ effect obtained by the interference between two or more superimposed grid pattern layers therein where the superimposed grid pattern layers are located on opposite surfaces of a transparent contact lens such that the grid pattern layers are separated by the thickness of the lens allowing for maximum parallax to take place.
Claim 9
Dependent Claim 65 words
A cosmetic contact lens which contains an iris region which provides for a moir',acu/e/ effect obtained by the interference between two or more superimposed grid pattern layers therein where the superimposed grid pattern layers are located on opposite surfaces of a transparent contact lens such that the grid pattern layers are separated by the thickness of the lens allowing for maximum parallax to take place.
Claim 10
Dependent Claim 19 words
The cosmetic lens of claim 7 wherein the grid patterns are of the same or generally the same shape.
Claim 11
Dependent Claim 16 words
The cosmetic lens of claim 7 wherein the grid patterns are the same or different colors.
Claim 12
Dependent Claim 152 words
A cosmetic contact lens comprising an optically clear central visual region circumscribed by an area covering at least a portion of the iris, in which such circumscribing area comprises: (a) a primary substrate layer, forming the body of the contact lens that is transparent or partially transparent and has an upper surface and a lower surface, said surfaces separated by the physical thickness of the substrate material itself, said thickness functioning to allow for a parallax effect; (b) a posterior grid pattern layer having a posterior grid pattern therein containing opaque or partially opaque regions within said posterior pattern, said posterior grid pattern layer superposed on the lower surface of the primary substrate layer; and (c) an anterior grid pattern layer having an anterior grid pattern therein containing transparent or partially transparent regions within said anterior pattern, said anterior grid pattern layer superposed on the upper surface of the primary substrate layer.
Claim 13
Dependent Claim 152 words
A cosmetic contact lens comprising an optically clear central visual region circumscribed by an area covering at least a portion of the iris, in which such circumscribing area comprises: (a) a primary substrate layer, forming the body of the contact lens that is transparent or partially transparent and has an upper surface and a lower surface, said surfaces separated by the physical thickness of the substrate material itself, said thickness functioning to allow for a parallax effect; (b) a posterior grid pattern layer having a posterior grid pattern therein containing opaque or partially opaque regions within said posterior pattern, said posterior grid pattern layer superposed on the lower surface of the primary substrate layer; and (c) an anterior grid pattern layer having an anterior grid pattern therein containing transparent or partially transparent regions within said anterior pattern, said anterior grid pattern layer superposed on the upper surface of the primary substrate layer.
Claim 14
Dependent Claim 19 words
The cosmetic lens of claim 10 wherein at least one of the grid pattern layers comprise opaque colored regions.
Claim 15
Dependent Claim 41 words
The cosmetic lens of claim 10 wherein the anterior grid pattern layer positioned on the upper surface has its grid pattern comprising a patterned array of lenslets which image the grid pattern layer(s) positioned beneath it thereby providing a three-dimensional effect.
Claim 16
Dependent Claim 35 words
The cosmetic lens of claim 10 wherein the posterior grid pattern layer positioned on the lower surface has its grid pattern comprising a patterned array of lenslets which reflect the grid pattern layer(s) positioned above.
Claim 17
Dependent Claim 79 words
A contact lens comprising in the area thereof circumscribing the visual region: a. a first grid pattern containing opaque or partially opaque regions therein; b. a second grid pattern superimposed over the first grid pattern and containing opaque or partially opaque regions and transparent or partially transparent regions therein; c. a primary substrate layer having an upper surface and a lower surface; wherein the first and second grid patterns visually interact with one another to form a moire effect.
Claim 18
Dependent Claim 79 words
A contact lens comprising in the area thereof circumscribing the visual region: a. a first grid pattern containing opaque or partially opaque regions therein; b. a second grid pattern superimposed over the first grid pattern and containing opaque or partially opaque regions and transparent or partially transparent regions therein; c. a primary substrate layer having an upper surface and a lower surface; wherein the first and second grid patterns visually interact with one another to form a moire effect.
Claim 19
Dependent Claim 39 words
A cosmetic contact lens comprising an anterior grid pattern of solid and open regions upon its front surface, a carrier body with thickness, and a posterior grid pattern upon its back surface which interacts with the anterior grid pattern.
Claim 20
Dependent Claim 39 words
A cosmetic contact lens comprising an anterior grid pattern of solid and open regions upon its front surface, a carrier body with thickness, and a posterior grid pattern upon its back surface which interacts with the anterior grid pattern.
Claim 21
Dependent Claim 28 words
A cosmetic contact lens comprising an anterior array of lenslets upon its front surface, a carrier body with thickness, and a posterior grid pattern upon its back surface.
Claim 22
Dependent Claim 28 words
A cosmetic contact lens comprising an anterior array of lenslets upon its front surface, a carrier body with thickness, and a posterior grid pattern upon its back surface.
