Definitions

  • Knapp in U.S. Pat. No. 4,582,402
  • Knapp discloses a contact lens having, in its preferred embodiment, colored, opaque dots.
  • the Knapp lens provides a natural appearance with a lens that is simple and inexpensive to produce, using a simple one-color printed dot pattern.
  • the intermittent pattern of dots does not fully cover the iris, the invention provides a sufficient density of dots that a masking effect gives the appearance of a continuous color when viewed by an ordinary observer.
  • Knapp also discloses that the printing step may be repeated one or more- times using different patterns in different colors, since upon close examination the iris's of many persons are found to contain more than one color.
  • the printed pattern need not be absolutely uniform, allowing for the change or modification of the appearance of the fine structure of the iris.
  • the one-color Knapp lenses currently achieving commercial success have their dots arranged in an irregular pattern to enhance the structure of the iris.
  • neither the Knapp commercial lenses, nor the Knapp patent disclose or suggest a contact lens in which the color and design combine to change a person's eyes to a striking honey color.
  • a colored contact lens comprises a pupil section and an iris section surrounding the pupil section wherein the iris section is at least partly covered by an orange colorant having a red component.
  • a contact lens in another aspect of the invention, is provided to be worn by a person to change the appearance of a human iris to a honey color.
  • the contact lens comprises a non-opaque pupil section, an iris section surrounding said pupil section, and a colored, opaque intermittent pattern over said iris section that leaves a substantial portion of the pattern non-opaque, said pattern covering at least about 25% of the area of said iris section, the elements of said pattern being indiscernible to the ordinary viewer, said pattern being made up of an orange colorant, a hazel colorant, and a dark colorant.
  • a contact lens comprises a non- opaque pupil section, an iris section surrounding said pupil section, and at least two colored, opaque intermittent patterns over said iris section that leaves a substantial portion of the pattern non-opaque, said patterns covering at least about 25% of the area of said iris section, wherein the elements of a first pattern comprise orange colorant and the elements of a second pattern comprise hazel colorant.
  • non-opaque as used herein is intended to describe a part of the lens that is uncolored or colored with translucent coloring.
  • the term "ordinary viewer” is intended to mean a person having normal 20 — 20 vision standing about 5 feet from a person wearing the lenses of this invention.
  • Figure 1 illustrates a contact lens having a pupil section and an iris section.
  • Figure 2 illustrates an outermost starburst pattern for use on a contact lens.
  • Figure 3 illustrates an outer starburst pattern for use on a contact lens.
  • Figure 4 illustrates an inner starburst pattern for use on a contact lens.
  • Figure 5 illustrates a graph of reflectance versus wavelength of an orange colorant on a contact lens.
  • Figure 6 illustrates a graph of reflectance versus wavelength of a hazel colorant on a contact lens.
  • Figure 7 illustrates a graph of reflectance versus wavelength of a black colorant on a contact lens.
  • Figure 1 shows a contact lens 10. It has a non-opaque pupil section 20 in the center of the lens, and an annular iris section 22 surrounding the pupil section. For hydrophilic lenses a peripheral section surrounds iris section 22. A colored, opaque, intermittent pattern is located over the iris section 22, as shown in Figure 1. The pattern leaves a substantial portion of the iris section within the interstices of the pattern non-opaque. The non-opaque areas of the iris section 22 appear white in Figure 1.
  • the elements of the pattern are preferably dots, and especially preferred are dots, some of which run together, as shown in Figure 1. Certain portions of the iris section 22 are less densely covered with dots than other portions.
  • the opaque pattern or patterns can be made up of dots having regular or irregular, uniform or non-uniform shapes, for example, round, square, hexagonal, elongated, or other dot shapes.
  • the elements of the pattern may have a shape other than dots, so long as the elements are indiscernible to the ordinary viewer, cover between 10 and 30 percent, preferably about 20 or 25 percent of the iris, and leave a substantial portion of the iris section within the interstices of the pattern non-opaque.
  • the patterns that make up the portions of the iris can be islands of color or worms, corkscrews, starbursts, spokes, spikes, striations, radial stripes, zig-zags and streaks. In certain cases, a single color background is used to complement the multi-pattern design. These patterns blend with each other to provide a colored contact lens that enhances the structure of the iris of a person wearing the lens.
  • One embodiment of this invention includes a multiple color pattern that greatly improves the natural appearance of the wearer's iris, even over that of one and two color lenses.
  • three (or more) colored patterns are printed in three or more portions.
  • a first portion of the elements are a first shade and generally have a greatest concentration of dots or other elements located generally on the outside of, but within, the iris section, i.e. at or near the outer perimeter of the annular iris section. This section may be shaped as the outermost starburst.
  • a preferable first outside portion pattern or outermost starburst is shown in Figure 2. Black, or some other dark color such as gray, dark-brown or dark blue, is most often used as the color of the outermost starburst.
  • a second portion (the outer starburst) of the elements are a second shade, which is different from the first shade, and has elements with a greatest concentration located generally on the inside of the outermost starburst, and generally, although not always, surrounded by the outermost starburst portion.
  • a preferable second portion or outer starburst appears in Figure 3.
  • the outer starburst can be many colors, for example, blue, gray, brown, light blue, turquoise, violet, blue-violet, aqua, yellow, hazel, or green. Most preferably, the outer starburst is hazel.
  • a third portion (the inner starburst) of the elements are of a third shade, which is different from the second shade and either the same or different from the first shade.
  • This third portion has a greatest concentration of elements located generally, but not always, on the inside of the other two portions. Generally, the greatest concentration of elements of the third portion is surrounded by the concentration of elements of the other two portions.
  • a preferable third inside portion pattern preferably an inner starburst, appears in Figure 4. The preferred color for the inner starburst is orange, but other colors to be used include yellow, yellow-green, brown, yellow-brown, hazel and gold.
  • Figure 1 the preferred embodiment of the present invention, shows a combination of Figures 2, 3 and 4.
  • a first uneven border differentiates the outermost starburst and the outer starburst portions of the pattern elements, however, the elements of the outermost and outer starbursts overlap, mix and blend together, either in actuality or merely in perception, to create the desired effect.
  • a second uneven border differentiates the outer starburst and the inner starburst portions of the pattern, however, again the elements of the outer and inner starbursts overlap, mix and blend together, either in actuality or in perception. If the patterns of Figures 2, 3 and 4 are merged to form a three color lens, the uneven edge of the pattern shown in Figure 2 will merge and overlap with the pattern shown in Figure 3 to form the first uneven border between the outermost and outer starbursts.
  • the uneven edge of the pattern shown in Figure 4 will merge and overlap with the pattern shown in Figure 3 to form the second uneven border between the outer and inner starbursts.
  • the outer starburst may contain a pattern that extends further toward the periphery of the lens than the pattern of the outermost starburst. In other patterns, the outer starburst may contain a pattern that extends further toward the pupil section of the lens than the pattern of the inner starburst.
  • Alternative embodiments of the present invention include minimum and maximum distances of the uneven borders from the outer perimeter of the iris section.
  • the minimum distance of the first uneven border from the outer perimeter of the iris section is from about 5% to about 60% of the radial width of the iris section
  • the maximum distance of the uneven border from the outer perimeter of the iris section is from about 25% to about 95% of the radial width of the iris section
  • the minimum distance of the second uneven border from the outer perimeter of the iris section is from about 15% to about 75% of the radial width of the iris section
  • the maximum distance of the uneven border from the outer perimeter of the iris section is from about 50% to about 95% of the radial width of the iris section.
  • the minimum distance of the first uneven border from the outer perimeter of the iris section is from about 15% to about 50% of the radial width of the iris section, and the maximum distance of the uneven border from the outer perimeter of the iris section is from about 45% to about 95% of the radial width of the iris section, and the minimum distance of the second uneven border from the outer perimeter of the iris section is from about 15% to about 65% of the radial width of the iris section, and the maximum distance of the uneven border from the outer perimeter of the iris section is from about 60% to about 95% of the radial width of the iris section. In another embodiment, the minimum distance of the first uneven border from the outer perimeter of the iris section is from about 15% to about

  • the graph shows that a contact lens having the orange colorant on it, when measured spectrophotometrically, has a reflectance of about 6 reflective units between about 360 and about 540 nm. Between about 540 nm and about 620 nm, the reflectance rises to about 26 reflective units. Between about 620 nm and about 740 nm, the reflectance rises to about 33 reflective units.

  • the CIE Standard Observer is the observer data adopted by the CIE to represent the response of the average human eye, when light-adapted, to an equal energy spectrum. Unless otherwise specified, the term applies to the data adopted in 1931 for a 2 degree field of vision. The data adopted in 1964, sometimes called the 1964 observer, were obtained for a 10 degree, annular field which excludes the 2 degree field of the 1931 observer functions.
  • the colorant in the present invention can be measured spectrophotometrically.
  • CIE method of measurement and in particular the CIE 1976 Color Difference Equation:
  • Two panels containing the colorant of the present invention were measured spectrophotometrically in accordance with the CIE Color Notation System, using a standard of olive-gold #1133-67.
  • the olive-gold standard is 52.160 for L*, -3.384 for a*, and 32.585 for b*.L* for panel #1 was measured to be 52.142, while a* and b* measured -3.365 and 32.564 respectively.

A flat surface is covered by a photo resist material which becomes water insoluble when exposed to light. The photo resist material is covered with the pattern and exposed to light. The portion of the photo resist pattern is removed by washing with water and the resulting plate is etched to the required depth. Then the remainder of the photo resist material is mechanically removed.

  • the ink on the pad is allowed to dry slightly to improve tackiness, then pressed against the front surface of the contact lens, depositing the ink in the desired pattern over the iris section.
  • the pad must have enough flexibility to deform to fit over the convex front surface of the lens.
  • the printing step may be repeated one or more times using different patterns in different colors, since upon close examination, the iris's of many persons are found to contain more than one color.
  • the printed pattern need not be absolutely uniform, allowing for enhancement of the fine structure of the iris.
  • the deposited pattern is treated to render it resistant to removal from the lens under exposure to the ocular fluids that the lens will encounter when placed in the eye.
  • the exact method of preventing removal depends on the material of construction of the lens and the pattern. Mere air drying or heating the lens may suffice.
  • the techniques for coating the opaque pattern described in Wichterle, U.S. Pat. No. 3,679,504 (incorporated herein by reference), may be used.

  • a lens capable of changing the apparent color of the iris of a person wearing the lens and imparting a very natural honey appearance will be provided.
  • the steps used to deposit the intermittent pattern on the lens surface include using a first plate having depressions corresponding to the first portion or outermost starburst and filling the depressions with colorant of the first shade, preferably black.
  • the next step is pressing a first flexible pad against the first plate and subsequently pressing the first flexible pad against the surface of the lens (either side) thereby printing the first portion of the elements.
  • the next step involves using a second plate having depressions corresponding to the second portion or outer starburst and filling in the depressions with colorant of the second shade which is different from the first shade, preferably hazel.
  • the next step involves pressing the second flexible pad against a second plate and pressing the second flexible pad against the surface of the lens (either the same or the opposite surface) thereby printing the second portion of the elements.
  • the final step involves using a third plate having depressions corresponding to the third portion or inner starburst and filling the depressions with colorant of the third shade which is different from the second shade and is either the same or different from the first shade, preferably orange. This is carried out by pressing a third flexible pad against the third plate and pressing the third flexible pad against said surface of the lens (either side) thereby printing the third portion of the elements.
  • the resultant lens when worn, makes the iris of the wearer appear to be a striking honey color.
  • the steps listed above place an order to the printing of the portions on the lens, the order of printing is not important to the present invention and any other order of printing would be covered by the present invention. Further, the process described above may include the maximum and minimum distances, creating the uneven borders, previously listed in the alternative embodiments.
  • An alternative embodiment for printing the different layers on the iris section of the contact lens provides for ink-jet printing instead of pad printing of each layer. Ink-jet printing is accomplished without the need of pads or plates and can be administered at a higher resolution than pad printing, thereby providing for greater detail of each colored layer and a more natural final pattern on the iris section of the contact lens.
  • Using ink-jet printing also reduces the number of devices that make contact either with the contact lens or with other devices. For example, a silicon pad must make contact with a plate or cliche initially and then with the contact lens itself. Contact between the parts tends to wear down the parts, which will then require replacements. During the ink-jet process, the micro-nozzles do not physically make contact with the contact lens, nor with any other device. The chance of the micro-nozzle wearing out is thereby reduced.
  • the ink-jet printer is electronically controlled such that changing from one color layer to a different color layer can be done easily, by computer control.
  • each layer can be applied to the colored contact lens using an ink-jet process, thereby creating a colored contact lens capable of changing the apparent color of the wearer's iris to honey.
  • the present invention provides a contact lens capable of changing or modifying the appearance of the color of the iris to a striking honey color, while allowing visualization of the fine structure thereof and providing a natural appearance.
  • equivalent means may be substituted for those illustrated and described; and certain features may be used independently from others without departing from the spirit and scope of the invention as defined in the following claims.
