Description

Colored contact lens and method of manufacturing colored contact lens

The present invention relates to a colored contact lens that enables the wearer's eyes to appear larger and more contoured and shiny, while remaining natural by seamlessly blending with the eye. The invention further relates to a method for designing and fabricating a colored contact lens of the invention.

For cosmetic purposes, tinted lenses with one or more colorants dispersed in the lens or printed on the lens are in high demand. The colored contact lenses enhance the natural beauty of the eye, or provide a unique pattern on the wearer's iris, or provide a non-cosmetic pattern.

In general, there are two types of colored contact lenses. The first type uses a substantially transparent, enhanced color contact lens that allows transmission to reveal the color of the natural iris but combines with the natural color to create a new appearance. Such transparent tinted lenses are commonly used to turn light-colored eyes (eg, green) into slightly different shades (eg, light green). Such colored lenses may not turn the underlying dark brown iris into blue. The second type is such a opaque colored lens having a continuous opaque pattern that completely covers the iris or an intermittent opaque pattern that does not completely cover the iris. The opaque colored contact lens effectively and substantially modifies the wearer's eye color.

Some contact lens consumers have shown an interest in enhancing their eyes without dramatically changing the natural color of their eyes. They want their eyes to be larger and more distinct and shiny, while remaining natural by seamlessly blending with the eyes. However, such consumers do not want anyone to know that they are wearing contact lenses, and that any design should be natural.

Therefore, there is still a need for a colored contact lens that is capable of making the eye appear larger and contrast enhanced while being more conspicuous while maintaining the underlying iris structure and natural color of the wearer.

(for example, transparent mica sheets), and it is mainly based on the principle of thin film interference light to impart color. The optical thin metal oxide coating can include a single or multiple thin layers of metal oxide. The optically thin coating applied to the sheets contributes to an interference effect that allows the appearance to vary depending on the illumination and viewing conditions. The color is determined by the thickness of the coating, the refractive index, and the angle of illumination. The optical thin coating is also responsible for producing a rich, deep, glossy effect due to partial reflection of the metal oxide and partial transmission through the mica sheet. These pigments provide pearl luster and iridescent effects.

Pearlescent pigments with oxide coated mica flakes are available from the Englehard Company of Iselin, NJ under the "Mearlin Pigment" product line (such as "Hi-Lite Interference Color", "Dynacolor Pearlescent Pigment", "MagnaPearl", "Flamenco" ", "Celini Color") is commercially available.

In the case of pearlescent pigments, it is important during processing to minimize sheet breakage and maintain adequate levels of dispersion. Pearlescent pigments require mild handling during mixing and they should not be ground or subjected to prolonged mixing, milling or high shear because such operations can destroy the pigment. The particle size distribution, shape and orientation have a very large impact on the final appearance. Milling, high shear mixing or long processing of pearlescent pigments should be avoided as such operations can result in delamination of metal oxide coatings, sheet breakage, sheet agglomeration and sheet compression. Metal oxide delamination, compression, fragmentation and agglomeration will weaken the pearlescent effect.

The term "shining effect" as used herein is intended to describe the provision of a shine to the eye by using a combination of small elements in the design and inks that may be brighter in color than the rest of the pattern and/or have a pearlescent structure. This effect of the reflective appearance. Metal or pearlescent pigments can impart shine, shine, or brightness by the nature of their sheet type or structure. In addition, a shiny, sparkling or bright appearance can also be achieved by comparing the brightness and/or chromaticity of the ink color as compared to other portions of the pattern or compared to a natural iris. In CIELAB terminology, this would be equivalent to comparing the L* (lightness) or C* (chrominance) and/or natural iris of the rest of the printed pattern to the element that gives the appearance of shine, brilliance or brightness. High L* and / or C* values.

The process for molding a colored contact lens described in U.S. Patent No. 5,034,166, the entire disclosure of which is incorporated herein by reference. .

The present invention relates to a colored contact lens designed to enhance the natural color of the wearer's eyes and make them more conspicuous while providing a very natural look that ordinary viewing feels.

For example, some black eye contact lens consumers have shown an interest in enhancing their eyes without dramatically changing the natural color of their eyes. They want their eyes to look darker, more eye-catching, larger, and shiny, while remaining natural by seamlessly blending with the eyes. However, such consumers do not want anyone to know that they are wearing contact lenses, and that any design should be natural. Consumers of light (i.e., blue or green) and intermediate (i.e., light brown, light brown) contact lenses also exhibit similar interest in sharply and naturally enhancing their eyes.

Discovering such cosmetic effects (ie, enhancing the wearer's eye color and making them more eye-catching while providing a very natural look) can improve the wearer's eyes, especially their limbus, by adding a colored design to the contact lens. The contrast is achieved. This design can be applied by printing onto contact lenses by conventional means. The present invention has shown certain designs and colors that provide this color on the eye while blending with the natural color of the wearer's eyes. The invention described herein is a series of rings placed one above the other to provide the desired effect. This first printed layer has a diffuse pattern of gradient lattices that allow viewing of the underlying limbal and iris structures. The first print design of the present invention helps to provide both a natural appearance pattern and a natural contrast of the wearer's natural eyes, especially when the first print is overlapped with the second print. The first print blocks some of the light that reflects out of the underlying iris and allows for good fusion with natural eyes. The second printing is a circular annular speckle pattern comprising a plurality of annularly distributed irregular speckle shape clusters, and the speckle shape is composed of a plurality of small dots, and the circular annular speckle pattern has no Smooth inner and outer boundaries.

a second print is located on the inner side of the first print, and the circular border separates the first and second prints, wherein the circular border is flat or jagged, wherein the first color and the second color are different or the same, Wherein the first print and the circular border are concentric with the center of the contact lens. The width of the speckle circular pattern is about 30% to 90% of the width of the circular gradient lattice. The second print of the circular speckle pattern enhances the first print of the circular speckle pattern. The annular speckle pattern is superimposed with a circular gradient lattice pattern, wherein the inner diameter of the speckle pattern is smaller than the inner diameter of the gradient point ring and the centers of the rings are concentric with each other. The enhanced circular gradient lattice pattern provides an even more attractive design and feels even larger and more eye-catching than an unreinforced circular gradient lattice pattern.

The two laminates provide the desired colored design, which more covers and emphasizes the wearer's natural limbal ring and eye color as compared to the individual layers themselves. On the eyes, the pattern provides an attractive design and feels larger and more eye-catching. It has also been found that such cosmetic effects (i.e., enhancing the wearer's eye color and making them more conspicuous while providing a very natural appearance) are particularly effective for contact lens wearers with dark eyes and many other eye colors. This larger appearance is created by increasing the size of the design pattern such that it produces a larger pattern on the final lens to achieve the desired on-eye appearance with a larger iris. This first printed pattern of the present patent application is intended to cover the outer portion of the natural iris (outside the natural pupil area), the natural limbus, and the natural scleral segment just outside the natural iris. Thus, according to the present patent application, the first printed circular gradient dot pattern is increased to create a larger appearance and the appearance is enhanced by a second printed circular speckle pattern. It has further been found that the above contact lens further comprises a third print of a third color which imparts natural black eye brightness and depth. The same or additional colors, tones, and shadows add further depth, thereby providing a contact lens that is capable of making subtle changes and enhancing the color of the iris of the black-eyed person wearing the lens while imparting a very natural appearance. According to the application, the third printing is a first tulip flower ring pattern, the third printing having an outer diameter that is identical to or smaller than the outer diameter of the second printing; the third printing has a smaller inner diameter than the second printing The path, wherein the tulip flower has a shape comprising two elements: the first element has a thicker center and a worm-like shape having a first end and a second end; the second element is a mirror image of the first element The first end of the first element and the first end of the second element converge to touch each other, and the second end of the first element and the second end of the second element diverge, wherein the tulip flower is repeatedly looped around The ring in which the convergence point is directed inwardly, wherein the first color, the second color, and the third color are different or the same, wherein the first print, the second print, and the third print are concentric with the center of the contact lens.

It is still further found that the contact lens further comprises a fourth print of a third color, the fourth print being a second tulip flower ring pattern, wherein the tulip flower is repeatedly formed around the ring to form a divergent point pointing inward (toward the pupil) The ring comes to form a second tulip garland. The fourth print has a circumferentially annular scented flower to form a ring in which the divergent point points inward (toward the pupil), while the third print has a surrounding annular gold scented flower to form a ring in which the convergence point points inward (toward the pupil). Since the third print pattern and the fourth print pattern are offset, room is given to emphasize the same or additional colors to impart a more natural appearance to the contact lens pattern and to add further depth.

According to the present patent application, the eye may be rendered shiny, blazed or bright by using a combination of small elements in the design and inks that may be brighter in color or have a pearlescent structure than the rest of the pattern. Metal or pearlescent pigments can impart shine, shine, or brightness by the nature of their sheet type or structure; however, shiny, sparkling, or bright appearance can also be compared to other parts of the pattern or to natural irises. This is achieved by increasing the brightness and/or chromaticity of the ink. In CIELAB terminology, this would be equivalent to comparing the L* (lightness) or C* (chrominance) and/or natural iris of the rest of the printed pattern to the element that gives the appearance of shine, brilliance or brightness. High L* and / or C* values.

In the CIELAB color space, the L* value refers to the brightness of the color compared to the grayscale ranging from black to white. C* refers to the color of the color, or the degree of deviation of the color away from the gray level. This is similar to, but not identical to, color saturation. The hue angle h° refers to the hue of colors that can be considered as the basic color name: red, orange, yellow, green, blue, and purple.

In order to impart shine, shine or brightness to the contact lens, the expected element should be between 10 and 90 L* units higher than the other colors used in the cosmetic lens, or the C* of the intended element should be other than the other colors used in the cosmetic lens. Between 10 and 90 C* units. Ideally, both L* and C* should be between 10 and 90 units higher than the other colors used in cosmetic lenses.

For example, a print having a black outer ring and some brown speckle pattern elements intended to be fused into the eye may also include some spots, such as a small flame shape that may be orange or yellow in color, and may or may not include pearl light. Pigments, such as mica. By its nature, the orange and yellow colors have higher L* and C* values than brown because brown is considered to be low chroma orange and is not considered to be a hue by itself. In this example, orange and yellow will be at least 10 L* units and/or C* units higher than the black and brown used in the lens.

The hue intended to impart a shiny element may or may not be similar to the ink in the remainder of the printed pattern. For example, blue elements with higher L* and C* units can be used on this cosmetic lens that would otherwise be brown and black.

In one aspect, the present invention provides a colored contact lens comprising a first print of a first color and a second print of a second color, wherein the first print is a circular gradient lattice, wherein The second printing is a circular annular speckle pattern, wherein the circular speckle pattern comprises a plurality of annularly distributed regular or irregularly shaped clusters, wherein the regular or irregular shapes are composed of a plurality of dots, wherein The annular speckle pattern has a matte inner and outer boundary, wherein the second print is located inside the first print, wherein the first color and the second color are different or the same, wherein the first print And the second print is concentric with the center of the contact lens.

As is well known in the art, colors are generally illustrated primarily by the following interrelated terms: hue, chroma, intensity, saturation, illuminance, brightness, value, and opacity.

The term "different colors" is intended to describe that the two colors differ in at least one of hue, chroma, intensity, saturation, illuminance, brightness, value, and opacity. As used herein, the term "second color is different from the first color" (or a similar language) is intended to mean that the two colors belong to completely different colors, such as blue and light brown; or both colors are the same Hue, but with different brightness, values, such as light blue and dark blue.

The term "circular gradient lattice" is intended to mean gradually increasing the local colored point coverage of the ring in the radial direction (from the center to the edge) by increasing the printing density. For example, a greater number of printed colored dots in the region near the outer peripheral edge of the ring causes the outer peripheral edge appearance of the ring to be deeper than the inner peripheral edge of the ring. Alternatively, although the pitch of the center of each dot is fixed, a larger colored dot in the region near the outer peripheral edge of the ring causes the outer peripheral edge appearance of the ring to be deeper than the inner peripheral edge of the ring. Alternatively, the print density (i.e., circular blank) can be reduced by removing the printed area, such as by removing the print from the high print density area. The inner peripheral edge of the ring refers to the edge closest to the center of the colored lens. The outer peripheral edge of the ring refers to the edge furthest from the center of the colored lens. Alternatively, the array of gradient points can be composed of consistent dot densities.

The printed colored dot areas or empty areas may have any shape, regular or irregular, such as circular, oval, triangular, square, hexagonal, elongated, and the like. All colored areas or empty areas may have similar or different shapes. Preferably, all of the printed dot areas or empty areas have substantially similar shapes. More preferably, all of the printed dot areas or empty areas have a circular shape.

The dot size range is preferably from 0.01 mm to about 0.5 mm. The spacing between the points is preferably from 0.01 mm to about 0.3 mm. Also, the removed printed areas are from 0.01 mm to about 0.3 mm (i.e., circular blanks) with a pitch of from 0.01 mm to about 0.3 mm.

Figure 1 shows a prior art contact lens as an example. The contact lens has a light transmissive pupil section 20 at the center of the lens and an annular iris section 21 surrounding the pupil section. For hydrophilic lenses, the transparent perimeter section 22 surrounds the iris section 21. A colored, opaque, discontinuous pattern is located over the entire iris section 21, as shown in FIG. This pattern leaves most of the iris section within the light transmissive gap of the pattern. The light transmissive area of the iris section 21 appears white in Figure 1.

Fig. 2 schematically shows, by way of example, a "first print pattern" composed of a circular gradient lattice. Preferably, the dots, preferably opaque, may have any shape, regular or irregular, such as circular, oval, triangular, square, hexagonal, elongated, and the like. All points can have similar or different shapes. Preferably, all points have substantially similar shapes. More preferably, all points have a circular shape. The first print pattern is concentric with the center of the lens and has a substantially uniform outer peripheral edge and a substantially uniform inner peripheral edge. The outer peripheral edge of the first print has a diameter of from about 12.5 mm to about 15 mm, and the width of the first print is from about 0.8 mm to about 3.5 mm, and preferably from about 2.0 mm to about 3.0 mm. The first print can be of any color, for example, black, blue, gray, brown, light blue, cyan, purple, deep purple, blue purple, light green, yellow or green. The preferred color of the first print is black or brown.

Figure 3 shows a "second print pattern" of a circular annular speckle pattern. According to the present application, the circular speckle pattern includes a plurality of annularly distributed clusters of regular or irregular shapes, such as a circle, an oval, a triangle, a square, a hexagon, an elongated shape, etc., wherein Equal rules or irregular shapes consist of a large number of dots. According to the invention, a large number of dots refer to from 4 to 2500, preferably from 10 to 1500, more preferably from 15 to 500 and even more preferably from 20 to 300. a dot. The width of the speckle circular pattern is about 30% to 90% of the width of the circular gradient lattice.

Figure 4 illustrates a "third print pattern" of a tulip pattern in accordance with the present invention. The third printing is a first tulip flower circular pattern having a shape including two elements: the first element has a thicker center and a worm-like shape that is thinner at the first end and the second end; the second element is a mirror image of an element, the first end of the first element and the first end of the second element converge to touch each other, and the second end of the first element and the second end of the second element diverge, wherein the tulip flower is surrounded The ring is repeatedly formed in a ring shape, and the convergence point is directed inward to form a U-shaped cup shape.

The third element is a reduced version of the size of the first element and is located within the U-cup and contacts at least one side.

According to the invention, the tulip flower shape may contain all three elements or, as the case may be, only the first two elements. This shape is repeated annularly around to form a ring in which the convergence point points inward.

Figure 5 illustrates a "fourth print pattern" of a second tulip pattern in accordance with the present invention. The second tulip flower pattern is also formed by the shape of a tulip flower that has been repeated around the ring. The second tulip flower pattern is identical to the first tulip flower pattern shown in FIG. 3 except that: 1) the tulip flower shape is annularly repeated to form a ring in which the convergence point points inward toward the center of the contact lens pattern; 2) The tulip flower shape is smaller or larger.

6 illustrates an example of a contact lens that includes two print patterns to form a reinforced outer ring pattern that is a combination of the circular gradient lattice pattern of FIG. 2 and the circular annular speckle pattern of FIG. . The inner diameter of the circular speckle pattern is smaller than the inner diameter of the gradient point ring and the centers of the rings are concentric with each other. This circular speckle pattern produces a better fusion with the natural iris.

Figure 7 illustrates an example of a contact lens containing three print patterns (Figures 2, 3, and 4) in accordance with the present invention. The topmost pattern of the design of Figure 7 is specifically intended to increase the appearance of the iris diameter, the three printed patterns of the darkly contoured outer ring. The circular speckle pattern (Fig. 3) is superimposed with the gradient dot pattern (Fig. 2). The circular speckle pattern includes a plurality of annularly distributed regular or irregularly shaped clusters, wherein the regular or irregular shapes are composed of a plurality of dots. The circular speckle pattern has a matte inner and outer boundary. According to the invention, the speckle circular pattern has a width which is from about 30% to about 90%, preferably from about 35% to about 80%, and more preferably from 40% to 70% of the width of the toroidal gradient lattice. %. When the layers are evaluated separately, the inner diameter of the speckle pattern is smaller than the inner diameter of the gradient point loop and the centers of the rings are concentric with each other. This speckle pattern creates a better blend with the natural iris. Figure 6 shows a pattern combination forming a reinforced outer ring pattern.

Figure 8 illustrates a third example of a contact lens containing four print patterns (Figures 2, 3, 4, and 5) in accordance with the present invention. The topmost pattern of the design of Figure 8 is specifically intended to increase the appearance of the iris diameter, the four printed patterns of the darkly contoured outer ring. The fourth layer is a second tulip flower ring pattern consisting of a similar tulip flower shape, the tulip flower shapes repeating around the ring in a different manner than the first tulip flower ring pattern.

The second tulip flower circular pattern also has a shape including two elements: the first element has a worm-like shape having a thicker center and being thinner at the first end and the second end; and the second element is a mirror image of the first element The first end of the first element and the first end of the second element converge to touch each other, and the second end of the first element and the second end of the second element diverge, wherein the tulip flower is repeatedly looped around To form a loop, the point of dispersion is directed inward (toward the pupil) to create a U-shaped cup shape.

The third element is a reduced version of the size of the first element and is located within the U-cup and contacts at least one side.

This shape can contain all three elements or, as the case may be, only the first two elements. For the first tulip print pattern layer shown in Figure 4, this shape is repeated annularly around to form a loop in which the convergence point is directed inward (toward the pupil). For the second tulip print pattern shown in Figure 5, the other pattern layers use this shape and are also annularly repeated around to form a loop, but the diverging points are directed inward (toward the pupil).

The combination of the four patterns creates a thick dark outer ring and a thick long wave randomly overlapping lace-like structure fused with both the other layers and the natural iris, so that there is a non-covered area and two overlapping layers to create a natural iris It blends well and provides a deep, sparkling or shiny design to the appearance of the lens.

A combination of four patterns is shown in FIG. The first tulip print in this design is approximately 85% to 95% of the diameter of the reinforced outer ring print. Further, the second tulip pattern is approximately 80% to 95% of the diameter of the reinforced outer ring print pattern.

On the eye, the pattern according to the invention provides an attractive design, feels larger and more eye-catching.

Colored contact lenses can be made by directly applying ink to the preformed contact lens. A preferred method for applying ink to a contact lens in accordance with the present invention is by printing (e.g., pad printing and/or ink jet printing) using an ink, preferably a water based ink.

The ink typically includes at least one color former, a binder polymer, and a solvent. The inks may optionally include crosslinkers, wetting agents, surfactants, monomers, polymerization initiators, antimicrobial agents, antioxidants, anti-fouling agents, and other additives known in the art.

The colorant includes at least one dye or preferably a pigment. Conventional and/or pearlescent pigments can be used in the present invention.

The solvent can be water (water based ink) or any suitable organic solvent (organic solvent based ink). Any known suitable solvent may be used as long as they can dissolve the binder in the ink of the present invention and contribute to the stability of the colorant. Examples of preferred solvents include water, or water mixed with one or more co-solvents. Alternatively, organic solvents such as ethanol, ethylene glycol, ketones, esters, methyl ethyl ketone, cyclopentanone, and cyclohexanone may be used.

"Binder polymer" refers to a crosslinkable polymer that includes a crosslinkable group and can be crosslinked or by chemical or physical means (eg, moisture, heat, UV radiation) Etc.) can be crosslinked upon initiation to capture or bond the colorant onto or into a contact lens, such as an item known in the art.

The term crosslinkable group is used broadly herein and is intended to encompass, for example, functional groups well known to those skilled in the art and photocrosslinkable or thermally crosslinkable groups. It is well known in the art that a pair of matched crosslinkable groups can form covalent bonds or linkages under known reaction conditions: for example, redox conditions, dehydration condensation conditions, addition conditions, substitution (replacement) conditions, freedom Base polymerization conditions, 2+2 cycloaddition conditions, Diels-Alder reaction conditions, ROMP (open-loop metathesis polymerization) conditions, vulcanization conditions, cationic crosslinking conditions, and epoxy resin hardening conditions. For example, an amine group can be covalently bonded to an aldehyde (a Schiff base formed by an aldehyde group and an amine group can be further reduced); a hydroxyl group and an amine group can be covalently bonded to a carboxyl group; a carboxyl group and a sulfo group can be used. Covalently bonded to the hydroxy group; the fluorenyl group may be covalently bonded to the amine group; or the carbon-carbon double bond may be covalently bonded to another carbon-carbon double bond. Exemplary covalent bonds or linkages formed between pairs of crosslinkable groups include, but are not limited to, alkanes (carbon-carbon single bonds), olefins (carbon-carbon double bonds), esters, ethers, acetals, ketals, Vinyl ether, urethane, urea, amine, decylamine, enamine, imine, hydrazine, hydrazine, imido ester, carbonate, orthoester, phosphonate, phosphinate, sulfonate , sulfinate, sulfide, sulfate, disulfide, sulfinamide, sulfonamide, thioester, aryl, decane, decane, heterocycle, thiocarbonate, thioamine Acid esters and phosphonium amines.

Exemplary crosslinkable groups include, but are not limited to hydroxyl, amine, acyl group, sulfhydryl group, -COOR (R and R 'are hydrogen or C ₁ lines to C ₈ alkyl groups), halide (chloride, bromide , iodide), hydrazine chloride, isothiocyanate, isocyanate, monochlorotrimium, dichlorotrimethylene, mono or dihalopyridine, mono or dihalobiguanide, phosphite, malayan Amine, aziridine, sulfonium halide, hydroxy amber ylide, hydroxy thiosuccinimide, imidate, hydrazine, azidonitrophenyl group, azide, 3-(2- Pyridyl) propionamide, glyoxal, aldehyde, epoxy resin, ethylenically unsaturated free radical.

The binder polymer in the ink can be any polymer that is compatible with the lens material. The binder polymer can be composed of vinyl alcohol, vinyl butyral, vinyl acetate, acrylic acid, methacrylic acid, hydroxyl C ₁ to C ₆ acrylic acid and alkyl methacrylate, and amine C ₁ to C ₈ acrylic acid. It is prepared by polymerization of a monomer such as alkyl methacrylate, acrylic acid and glyceryl methacrylate, vinyl pyrrolidone, vinyl chloride, hydroxyethyl methacrylate, dimethyl decylamine or the like. Mixtures of such monomers can be made to form a variety of different copolymers. Other copolymers may include a variety of different cellulosic resins, polyesters, polyurethanes, polyureas, or polyamines having at least one crosslinkable group. Preferably, the monomers used in the preparation of the binder polymer are the same as those used in the manufacture of the lens.

The ink used to print the colored lenses of the present invention can be prepared according to any known suitable method. For example, a solution of a binder polymer and a solvent is first prepared and this solution is mixed with a paste containing a colorant to form an ink.

Printing system well known in the art (e.g., see Spivak (Spivack) U.S. Patent Nos 3,536,386; U.S. Pat. Nos Knapp (Knapp) of 4,582,402 and 4,704,017; Rawlings (Rawlings) et al. U.S. Patent No. 5,034,166, the disclosure of which is incorporated herein in its entirety. The following is a typical example of such printing. The image is etched into the metal to form a cliche. Place the lead plate in the printer. Once in the printer, the lead plate is inked by an open ink cell scraping system or by sliding the ink cup over the image. The silicone pad then picks up the inked image from the cliche and transfers the image to the contact lens. The silicone pad is made of a material that includes an anthrone that can vary in elasticity. The properties of the fluorenone material permit the ink to temporarily stick to the pad and completely release the ink from the pad as it contacts the lens or mold. Suitable pad printing structures include, but are not limited to, Tampo type printing structures (Tampo vario 90/130 type), rubber stamps, thimbles, doctor blades, direct printing, or transfer, as they are known in the art.

Any known suitable silicone pad can be used in the present invention. Silicone pads are available on the market. However, different pads can give different print qualities. Those skilled in the art should know how to select a pad for a given ink.

The lead plate can be made of ceramic or metal (for example, steel). When the cliche is made of steel, it will be desirable to neutralize the pH of the water-based ink by adding a buffer (e.g., like phosphate) (e.g., adjusting the pH to 6.8-7.8). The image can be etched into the lead plate by any method known to those skilled in the art, such as by chemical etching or laser ablation. It is also desirable to clean the cliche after use, such as, for example, immersion in a solvent, sonication, or mechanical abrasion, using standard cleaning techniques known to those skilled in the art.

It should be understood that the front (convex) surface or the back (concave) surface of the lens may be printed, but it is presently preferred to print the front surface.

The use of an inkjet printing process to print lenses is described in the published U.S. Patent Application Serial Nos. 2001/0050,753, the disclosure of which is incorporated herein by reference.

According to a preferred embodiment, the colored contact lens may further comprise a clear coating covering at least the colored regions of the lens. The transparent coating layer can be formed on the colored regions by applying a layer of a transparent polymerizable solution without any colorant to the surface of the lens using color printing and then polymerizing the layer of the transparent polymerizable solution. The clear coating minimizes the leaching of the colorant and can enhance the wearer's comfort.

Alternatively, the colored contact lenses of the present invention can be made in accordance with a similar on-die printing process as described in U.S. Patent No. 5,034,166, the entire disclosure of which is incorporated herein by reference. The ink may first be applied to the molding surface of one or more mold portions by using pad printing (or transfer printing) or ink jet printing to form a colored coating (with color image). The colored coating can be applied to the molding surface defining the back (concave) surface of the contact lens or to the molding surface defining the front (convex) surface of the contact lens or to both mold portions. Preferably, a colored coating (with a color image) is applied over the molding surface defining the front surface of the contact lens.

Optionally, the transferable coating can be applied to the molding surface of the mold by pad printing prior to application of the ink. The transfer coating is intended to describe a coating that can be separated from the molding surface of the mold and integrated with the contact lens body molded in the mold. The transferable coating can be applied to the molding surface of the mold by any suitable technique, such as, for example, spraying, printing, brushing, or dip coating. The transferable coating can be prepared from a solution comprising a polymerizable component and without any colorant. For example, a substantially uniform transferable coating of thickness (less than 200 microns) can be prepared by spraying a molded surface with a solution or prepolymer or solution having the ink component to be used or a lens forming material to be used. This transferable coating can be dried or cured as appropriate to form a transferable clear film (without any pigment but optionally with a dye comprising a reactive dye). One or more colored patterns can then be printed on the transferable coating or film. A colored lens can be made by applying a transferable coating prior to printing, wherein the printed colored pattern is embedded directly beneath the film from which the transferable coating is applied. Such lenses are more comfortable to wear and are much less affected by the colorant leached from the colored lenses.

After printing the ink of the present invention on the molding surface of the mold, the printed ink can be cured by UV or other actinic radiation to form a colored film in accordance with the present invention. It is desirable that the printed ink be cured in an actinic manner to minimize the loss of pattern sharpness of the colored coating produced by subsequent filling of the lens forming material.

Lens molds for making contact lenses are well known to those skilled in the art and are used, for example, in cast molding or spin casting. For example, a mold (for cast molding) typically includes at least two mold regions (or portions) or mold halves, namely first and second mold halves. The first mold half defines a first molded (or optical) surface and the second mold half defines a second molded (or optical) surface. The first and second mold halves are configured to receive each other such that a lens forming cavity is formed between the first molding surface and the second molding surface. The molding surface of the mold half is the cavity forming surface of the mold and is in direct contact with the lens forming material.

Methods of making mold regions for casting molded contact lenses are generally well known to those skilled in the art. The method of the present invention is not limited to any particular method of forming a mold. In fact, any mold forming method can be used in the present invention. The first and second mold halves can be formed by various techniques such as injection molding or lathe machining. Examples of suitable methods for forming the mold halves are disclosed in U.S. Patent No. 4,444,711 to Schad; 4, 460, 534 to Boehm et al.; 5, 843, 346 to Morrill; and 5, 894, 002 to Boneberger et al. .

Almost all of the materials known in the art for making molds can be used to make molds for making contact lenses. For example, polymeric materials such as polyethylene, polypropylene, polystyrene, PMMA, Topas® COC grade 8007-S10 can be used (from Frankfurt, Germany and the United States and Summit, New Jersey). Ticona GmbH's ethylene and norbornene transparent amorphous copolymer). Other materials that allow UV transmission, such as quartz glass and sapphire, can be used.

Any lens forming material can be used in the present invention and is not currently considered to be a critical part of this aspect of the invention. Suitable lens forming materials for the manufacture of contact lenses are illustrated by a number of authorized U.S. patents and are familiar to those skilled in the art. Preferred lens forming materials are capable of forming a hydrogel. The lens forming material may comprise one or more prepolymers, optionally one or more ethylene monomers and/or macromonomers, and optionally further comprising a plurality of different components, such as photoinitiators, visibility coloring agents, fillers, etc. . It should be understood that any anthrone-containing prepolymer or any anthrone-free prepolymer may be used in the present invention.

A preferred group of lens forming materials are water soluble and/or meltable prepolymers as described above. It will be advantageous for the lens forming material to comprise primarily one or more prepolymers which are preferably in substantially pure form (e.g., purified by ultrafiltration). Thus, after cross-linking/polymerization by actinic radiation, the contact lens may actually no longer require subsequent purification, such as complex unpolymerized component extraction. Additionally, the crosslinking/polymerization may be carried out in the absence or absence of a solvent such that subsequent solvent exchange or hydration steps are not necessary.

Those skilled in the art should be well aware of how to photocuring or thermally curing the lens forming material in the lens forming cavity.

In a preferred embodiment, when the lens forming material is a solution, a solvent free liquid, or optionally a melt of one or more prepolymers in the presence of other components, a reusable mold is used and The actinicizing lens forms a material to form a colored contact lens under the spatial constraints of actinic radiation. Examples of preferred reusable molds are U.S. Patent Application Serial No. 08/274,942 filed on Jul. 14, 1994, 10/732,566 filed on Dec. 10, 2003, and filed on Nov. 25, 2003. /721,913, and those disclosed in U.S. Patent No. 6,627,124, the entireties of each of which are incorporated herein by reference.

In this case, the lens forming material is placed in a mold composed of two mold halves which do not touch each other but are arranged with a narrow gap of an annular design therebetween. The gap is coupled to the mold cavity such that excess lens material can flow into the gap. Instead of a polypropylene mold that can only be used once, a reusable quartz, glass, or sapphire mold can be used because after the lens is produced, the mold can be cleaned and quickly dried using water or a suitable solvent to effectively remove uncrosslinking. Prepolymer and other residues. The mold may also be re-used by the Summit, New Jersey City Ticona GmbH of Frankfurt, Germany and the company Topas ^® COC grade 8007-S10 (clear norbornene and ethylene amorphous copolymer) is made. Since the mold halves do not contact each other in the area of the lens to be produced (i.e., the cavity or the actual mold surface), the damage caused by the contact is eliminated. This ensures a long service life of the mold, which in particular also ensures a high reproducibility of the contact lenses to be produced.

The two opposing surfaces (front and back surfaces) of the contact lens are defined by two molding surfaces, while the edges are defined by the spatial limitations of actinic radiation rather than by the mold walls. Typically, the lens forming material is crosslinked only in the area bounded by the two molding surfaces and the protrusions of the space-limited well defined perimeter boundary, and any lenses outside the perimeter boundary of the space restriction and immediately adjacent thereto The forming material is not crosslinked and thus the edge of the contact lens should be a smooth and precise reproduction of the spatially constrained size and geometry of the actinic radiation. U.S. Patent Application Serial No. 08/274,942, filed on Jul. 14, 1994, 10/732,566, filed on Dec. 10, 2003, filed on Such a method of making a contact lens is described in the entire disclosure of which is hereby incorporated by reference.

The spatial limitation of actinic radiation (or the spatial constraint of the energy impact) can be achieved by masking a mold that is at least partially impermeable to the particular form of energy used (e.g., U.S. Patent Application Serial No. 08/274,942, filed on Jul. 14, 1994. And the U.S. Patent No. 6,627,124, the entire disclosure of which is incorporated herein by reference in its entirety in its entirety, or in the form of the the the the the the the Part of the molds (e.g., U.S. Patent Application Serial No. 10/732,566, filed on Dec. 10, 2003, filed on The one shown is implemented. The energy used for crosslinking is radiant energy, in particular UV radiation, gamma radiation, electron radiation or heat radiation. The radiant energy is preferably in the form of substantially parallel beams, so that on the one hand a good limitation is achieved, and on the other hand Achieve efficient use of this energy.

It should be understood that the inks of the present invention should have good transferability of the colored coating from the mold to the contact lens and good adhesion to the molded lens. The resulting colored contact lens is substantially smooth and continuous on the surface containing the colored film.

Good transferability and adhesion can be caused to a large extent by the formation of interpenetrating networks during the curing of the lens forming material in the mold. Without limiting the invention to any particular mechanism or theory, it is believed that the ink binder of the present invention can form an interpenetrating network (IPN) from the lens material of a hydrogel lens. The ink of the present invention adheres to the lens by IPN formation without the need for reactive functional groups in the lens polymer. The lens forming material is crosslinked to form an IPN in the presence of a crosslinked binder polymer in the colored film. It will be appreciated that some (residual) ethylenically unsaturated groups in the binder polymer may not be consumed during the curing of the colored coating. The residual ethylenically unsaturated groups may undergo a crosslinking reaction to bond the binder polymer to the lens material during curing of the lens forming material in the mold.

It is also understood that the adhesion between the lens and the ink can be enhanced by a direct bond (bond formation) between the binder polymer and the lens polymer. For example, a binder polymer containing a nucleophilic group can be reacted with a lens polymer containing an electrophilic group such as an epoxy resin, an acid anhydride, an alkyl halide, and an isocyanate. Alternatively, the ink can be bonded to the lens by having an electrophilic group in the ink binder polymer and having a nucleophilic group in the lens polymer. It is also possible to combine both nucleophilic and electrophilic functions into a binder polymer to make a curable ink.
