Description

  The present invention relates to a colored contact lens, and in particular, by providing a pattern colored in a novel manner, a color having a novel structure capable of giving an unprecedented cosmetic effect to the wearer's eyes. It is related with a contact lens.

  Conventionally, several colored contact lenses provided with a colored region have been proposed as a kind of contact lens worn by being superimposed on the cornea of the eye. For example, Japanese Patent Application Laid-Open No. 2002-174799 (Patent Document 1), WO00 / 54093 (Patent Document 2), and Japanese Translation of PCT International Publication No. 2008-511005 (Patent Document 3) all disclose colored contact lenses. Yes.

  By the way, the face of a person is important in interpersonal relationships, and therefore many women have traditionally applied makeup on their faces. In addition, the eye has a great influence on the impression of others, especially in the face, as there is a habit of saying that the eyes say something as much as the mouth. The above-mentioned colored contact lens is worn on the eyeball surface of the eye, which is a part of the face, and is placed in a state where it can be seen by a face-to-face person, so it affects the impression on others. May affect.

  Therefore, it is conceivable to wear the colored contact lens as described above in view of the cosmetic effect of improving the impression to others.

  However, with regard to the conventional colored contact lenses described in Patent Documents 1 to 3, the present inventor has examined based on sample evaluation and the like. It has come to the knowledge that the cosmetic effect of imparting fragility is still difficult to fully demonstrate.

  The colored contact lenses described in Patent Documents 1 and 2 are visually recognized on the exterior in order to make it easy to find a contact lens that has been dropped or to make it easier to check the position of the contact lens while wearing it. An easy ring-shaped colored fluorescent part and colored identification part are provided. In addition, the colored contact lens described in Patent Document 3 has a cosmetic effect. However, for the purpose of making the outer edge of the black eye clearly visible, it is merely provided with a ring-shaped colored portion that is easily visible on the appearance. Absent. In short, the colored contact lenses described in any one of Patent Documents 1 to 3 have the purpose of making the ring-shaped colored region clearly stand out on the appearance, so that the peripheral portion of the colored region has a clear line. It is formed, and the inner and outer peripheral edges of the colored region are merely lines that can be clearly seen.

  And with conventional colored contact lenses that have colored areas that clearly show the lines in this way, you can simply “make clear the different color parts on the eye” or “make the outer edge of the black eye clear and look big. "I can do different impressions for the people I meet." However, in the conventional structure, the colored region is formed with clear lines that are clearly visible for the purpose of making the object clearly stand out from the purpose. It is easy to perceive like a robot eye (prosthetic eye). Therefore, it is difficult to say that an ordinary person who is not a model or the like can achieve the purpose of the original cosmetic effect of giving a good impression by making the whole eye and face look beautiful.

JP 2002-174799 A WO00 / 54093 Special table 2008-511025 gazette

  The present invention has been made in the background of the above-mentioned circumstances, and its solution problem is a novel structure that can make the wearer's eyes look more natural and beautiful and exhibit the original cosmetic effect. It is to provide colored contact lenses.

  A feature of the present invention is that a pattern having a hue different from the iris of the eye to be worn is attached to the outer peripheral part outside the central part located on the pupil of the eye to be worn, On the other hand, a colored contact lens is characterized in that a gradation region is provided.

  By wearing the colored contact lens according to the present invention, a pattern having a hue different from that of the iris can be applied to the eye, and the interest of others can be attracted and impressed. Moreover, since such patterns are shaded by gradation (gradation), it is possible to give a soft and gentle image to others, unlike colored areas consisting only of clear and crisp lines. The intended cosmetic effect can be effectively exhibited.

  The cosmetic effect of the “pattern” having both “a hue different from the iris” and “gradation” according to the present invention is easy to understand when looking at the makeup on the face. That is, the makeup to be applied to the face is three-dimensional by using cosmetics having a hue different from the face at the time of no makeup, such as blue, green, purple, red, etc. in addition to brown, black, pink, etc. By giving a feeling and an image, and also by applying shades of gradation, the natural beauty is expressed while suppressing unnaturalness.

  And according to the colored contact lens according to the present invention, it becomes possible to apply makeup to the eyes with natural beauty that could not be realized by conventional makeup on the face, and impressing others. Effective cosmetic effects can be obtained by applying makeup to the eye itself, which has a great influence. In particular, in the conventional colored contact lens, the ring-shaped colored region is formed with a clear line, so as a makeup, it was just an artificial and uncomfortable impression. On the other hand, the colored contact lens of the present invention exhibits a similar effect to the makeup of “blurring” and “accommodating” depending on the gradation, and even a pattern that is colored on a part of the eye is a point makeup cosmetic. The effect can be effectively realized with a soft and natural impression. Specifically, for example, it is possible to harmonize the eye shadow and the like colored on the eyelid with makeup and the pattern colored on the eye by adjusting the hue and gradation of each other, The cosmetic effect of the colored contact lens according to the present invention can be exhibited even more advantageously.

  Further, in the colored contact lens according to the present invention, a mode in which the gradation region is provided at least in the outer peripheral portion of the pattern can be suitably employed.

  According to this aspect, by providing a gradation region at least on the outer peripheral portion of the pattern, the color of the pattern is adapted to the color of the portion existing on the outer peripheral side of the pattern with the gradation while wearing the colored contact lens. It becomes possible to make the pattern appear natural.

  In the colored contact lens according to the present invention, a mode in which an annular limbal ring is provided in the same hue as the iris of the eye to be worn can be suitably employed.

  According to this aspect, by providing a limbal ring on the outer peripheral portion of the cornea, a cosmetic effect such as a large corneal region (black-eye portion) can be obtained by the limbal ring. Note that the limbal ring of this aspect can be provided separately from the pattern having the improved region according to the present invention.

  Furthermore, when the above-described limbal ring is employed, a transition region in which the light transmittance changes may be provided with respect to at least one of the inner peripheral portion and the outer peripheral portion of the limbal ring.

  By providing a transition region in the limbal ring, it is possible to obtain a cosmetic effect that emphasizes tenderness and loveliness by making the corneal region (black-eye part) larger while showing the existence of the limbal ring itself naturally. It becomes possible.

  Moreover, in the colored contact lens which concerns on this invention, the aspect by which the said pattern is made into the cyclic | annular colored ring extended in a lens circumferential direction can be employ | adopted suitably.

  According to this aspect, it is possible to provide a colored ring around the pupil of the eye at the time of wearing, and by providing a gradation region on the inner periphery and / or outer periphery of the colored ring, the natural and familiar appearance is greatly increased. Without damaging, it becomes possible to change the appearance color of the cornea or to provide a cosmetic region having a color different from that of the cornea on the outer peripheral portion of the cornea.

  That is, especially by forming such a colored ring on the outer peripheral portion of the optical part, the cornea region can be enlarged without significantly deteriorating the natural appearance, or a colored region having a color different from that of the cornea is formed on the outer peripheral side of the cornea region. By doing so, it becomes possible to obtain a more excellent cosmetic effect.

  Furthermore, the colored ring as a pattern can be used in combination with an annular limbal ring formed with the same hue as the iris of the eye to be worn. In that case, it is desirable that a colored ring is formed on at least one of the inner peripheral side and the outer peripheral side of the limbal ring concentrically with the limbal ring.

  By forming the colored ring on the inner peripheral side of the limbal ring, for example, it is possible to improve the recognition of the color of the colored ring on the appearance. On the other hand, by forming a colored ring on the outer peripheral side of the limbal ring, for example, a hue transition region by gradation is provided at the boundary part from the black eye part to the white eye on the appearance, and the color harmony with the white eye part and the eyelid is adjusted. Can be achieved more effectively. When forming a colored ring on the inner peripheral side of the limbal ring, when forming a colored ring on the inner peripheral side of the colored ring or forming a colored ring on the outer peripheral side of the limbal ring It is also possible to provide limbal rings on both the inner and outer periphery sides of the colored ring by forming limbal rings on the further outer peripheral side of the colored ring.

  When forming a colored ring as a pattern on the outer peripheral portion of the optical unit, it is desirable to form the colored ring in an annular region having a radial dimension from the lens center of 4.0 mm to 7.5 mm. By forming a colored ring in a region having a radial dimension of 4.0 mm to 7.5 mm (diameter is 8.0 mm to 15 mm), adverse effects on the optical part are avoided as much as possible, and the cornea ( By appropriately leaving the white-eye portion without unnaturally increasing the black-eye portion, it is possible to more effectively obtain a colored ring that can be visually recognized on the appearance and can effectively exhibit the cosmetic effect.

  Furthermore, in the colored contact lens according to the present invention, an aspect in which an iris pattern is drawn in a region located on the inner peripheral side of the pattern is suitably employed.

  According to this aspect, the iris pattern is drawn on the inner periphery of the pattern, particularly the colored ring. The iris pattern may be in the form of dots, polygons, line segments, or a combination thereof, and the hue may be substantially the same hue as the iris, or a completely different hue, or may be aligned with the hue of the colored ring. For example, when selecting a hue that is substantially the same as the iris as the hue of the iris pattern, the impression that a colored contact lens is worn while giving a further sense of depth to the eyes when a third person visually recognizes it. It becomes difficult to give. In addition, when a hue that is completely different from the iris is selected as the hue of the iris pattern, a change in the hue of the iris is easily recognized by a third party. In particular, adopting an iris pattern can be expected to have a further cosmetic effect in combination with the colored ring according to the present invention.

  Moreover, when forming the colored ring as a pattern in the outer peripheral part of an optical part, it is desirable that the non-colored area | region is provided in the outer peripheral side of this colored ring.

  By providing such a non-colored region on the outer peripheral side of the colored ring, the outer diameter of the colored band can be set with a large degree of freedom regardless of the outer diameter of the contact lens.

  In the colored contact lens according to the present invention, it is not essential that the pattern having a gradation region formed with a hue different from the iris is formed in a ring shape surrounding the optical part. For example, such a pattern can be formed so as to be located at one place or a plurality of places on the circumference of the optical part in the outer peripheral part away from the optical part.

  Further, in the colored contact lens according to the present invention, the gradation region in the pattern is formed by a plurality of colored dots, the size of the colored dots, the number per unit area, the density of the colored dots themselves, A mode in which the light transmittance is changed and gradation is changed by changing at least one of the above is preferably employed.

  By coloring the lens using the colored dots in this way, it is possible to easily and accurately set the gradation in the pattern with a large degree of freedom by adjusting the size and density of the colored dots. For example, gradation as a change in light transmittance can be realized by gradually changing the density of colored dots, and various appearances can be achieved by configuring colored dots with a plurality of colors such as three primary colors. It is also possible to express a color gradation by expressing the upper color or changing the proportion of colored dots of each color. Furthermore, by forming the pattern with colored dots, even if the pattern reaches the pupil, it is possible to reduce adverse effects on vision.

  The pattern according to the present invention may be provided with a constant color region that spreads with a constant light transmittance in addition to the gradation region. The colored dots can be formed uniformly over the entire surface. As a result, the entire pattern composed of the constant color region and the gradation region can be formed with colored dots.

  Further, when realizing the gradation region with colored dots, the size, density, and density of the colored dots may be changed stepwise in addition to continuously changing in the radial direction. Specifically, for example, a solid colored dot having a suitable outer peripheral shape such as a circle or a heart shape and filled in the center is adopted, and the size of the colored dot is changed in multiple stages in the lens radial direction. Or, by adopting an annular colored dot having a suitable outer peripheral shape such as a circle or a heart shape and having a non-colored region in the center, the thickness of the annular line of such colored dots or the size of the central non-colored region It is also possible to realize gradation in the radial direction by changing the lens in a plurality of stages in the lens radial direction.

  Furthermore, the present invention is configured by combining a plurality of the colored contact lenses according to any one of the above aspects, and the patterns of the colored contact lenses are different from each other so as to correspond to the hue of the eye shadow. It features a colored contact lens set that is given a hue.

  According to this color contact lens set, a color contact lens having a hue pattern corresponding to the hue of the eye shadow can be selected. A further cosmetic effect can be achieved by combining the hue of the eye shadow and the hue of the pattern of the colored contact lens. In addition, since eye shadows can be used according to mood and atmosphere, colored contact lenses are provided in a set of a combination of multiple types of colored contact lenses having patterns of multiple colors. It can combine suitably. Moreover, it is also possible to apply to the colored contact lens which has the above-mentioned iris pattern, and can enjoy the combination of each color of an eye shadow, a coloring ring, and an iris pattern according to the mood and atmosphere at that time.

  Further, according to the present invention, the contact lens prepared in advance has a hue different from the iris of the eye to be worn and a gradation area on the outer peripheral portion outside the central portion located on the pupil of the eye to be worn. A method of manufacturing a colored contact lens with a provided pattern is also a feature.

  According to the method of the present invention, by using a contact lens manufactured in advance with predetermined optical characteristics and coloring at least one of the front and back surfaces, the target colored contact lens is realized, so that the optical characteristics It is possible to easily obtain a colored contact lens with an appropriate pattern while avoiding the influence on the surface as much as possible.

  In addition, as a method for applying a pattern, various known methods can be employed, and specifically, a pad printing method, an ink jet printing method, or the like can be given.

  In the colored contact lens structured according to the present invention, the shade of the color in the gradation region is given to the eye, so that it is natural for the eye of the wearer by coloring with consideration of color blur and familiarity. It was possible to make it possible to apply color without a sense of incongruity. As a result, natural makeup for the eyes can be realized, and an excellent cosmetic effect can be exhibited.

  Further, according to the method of the present invention, it is possible to easily and efficiently manufacture the colored contact lens according to the present invention with an appropriate pattern while ensuring high-precision optical characteristics.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an explanatory diagram showing an enlarged front view of the colored contact lens 10 as the first embodiment of the present invention. The colored contact lens 10 has a shape according to a conventionally known contact lens, and has a front surface and a spherical concave surface that are spherical convex so that they are worn on the surface of the cornea of the eye. And a spherical crown shape having a rear surface.

  The material of the colored contact lens 10 is not limited. For example, in addition to hard lenses such as RGP lens (oxygen permeable lens) and PMMA (polymethyl methacrylate), PHEMA (polyhydroxyethyl methacrylate) is used. Any soft contact lens such as a water-containing material such as a non-water-containing material such as an acrylic elastomer or a high oxygen-permeable material such as a silicone hydrogel can be used. In particular, the soft contact lens is preferably employed in the present invention because it generally has a large diameter and sufficiently covers the white eye 12 portion, and also has a small amount of movement on the cornea when worn compared to a hard contact lens. obtain.

  The colored contact lens 10 is a visual acuity correction contact lens that has a specific optical characteristic for the central region superimposed on the cornea to provide a correction function for abnormal vision such as myopia, hyperopia, and presbyopia. However, it may be a non-vision correcting contact lens that does not have such specific optical characteristics. When provided as a non-eyesight correction contact lens, it can be used, for example, as a cosmetic lens (beauty or fashionable contact lens).

  The colored contact lens 10 of the present embodiment has an outer diameter dimension (DIA) that covers the entire portion of the black eye 14 of the eye, as shown in FIGS. In addition, the white eye 12 can be covered with a predetermined width. That is, the boundary line (limbal) 16 between the black eye 14 portion and the white eye 12 portion of the eye is positioned on the inner peripheral side with respect to the edge portion 18 that is the outer peripheral edge of the colored contact lens 10. The black eye 14 is an area where the color of the iris of the eye can be seen from the outside, but is an area where the iris can be seen through the transparent cornea. Therefore, the boundary line 16 is positioned on the cornea and its outer peripheral side. Can be understood as a boundary line with the white sclera.

  Furthermore, the colored contact lens 10 is provided with a pattern 20 colored with a hue different from the iris of the eye to be worn in a specific region.

  In other words, the pattern 20 is formed with a hue different from the iris of the black eye 14 portion, so that the pattern 20 can be viewed by others with the colored contact lens 10 worn. The iris color of the human eye is black (black), dark brown (brown), blue (blue), etc. depending on the amount of the melanin pigment, but in order to obtain the desired cosmetic effect more advantageously, It is desirable to use hues separated by ± 60 or more in the hue circle. However, a human eye with a black iris can obtain a cosmetic effect by adopting various chromatic colors.

  In addition, if the hue of the pattern 20 is different from the iris among the three elements of the color, the pattern 20 can be seen by others in the wearing state of the colored contact lens 10, so that the saturation and brightness (tone) Can be adjusted in consideration of the purpose of the cosmetic effect. For example, if you want to make a strong impression of gorgeousness, a color tone (saturation of 100%, lightness of 50%), etc., which is “v” in the PCCS (Japan Color Research Institute color scheme) value is suitable. In the case where it is desired to bring out the color, a color tone (saturation of 15%, lightness of 92.5%) or the like that is set to “p” by the PCCS value is preferably employed. Such a color tone can be set with reference to makeup on the human face, in particular with reference to eye shadows and eye lines.

  Furthermore, in the present embodiment, the pattern 20 is formed as a colored ring 24 that extends in the lens circumferential direction on the same central axis as the lens geometric central axis 22 and spreads in an annular shape.

  The colored ring 24 that is the pattern 20 is formed so that the boundary line 16 of the eye to be worn extends in the circumferential direction so as to overlap the colored ring 24 over the entire circumference. That is, the coloring ring 24 has a radial width that extends only in the radial direction across both the inner peripheral side and the outer peripheral side of the boundary line 16, and the coloring ring 24 is provided on the inner peripheral side of the boundary line 16. Is superimposed on the black eye 14, and the coloring ring 24 is superimposed on the white eye 12 on the outer peripheral side of the boundary line 16.

  It should be noted that the coloring ring 24 is positioned at the outer peripheral portion where the central portion located on the pupil 26 is out of the outer peripheral side to such an extent that the coloring ring 24 hardly overlaps the pupil 26 in many situations of daily wear of the wearer. Therefore, it is desirable that the inner diameter dimension is set. That is, it is desirable that the colored ring 24 is formed on the outer peripheral portion of the optical unit so as to surround the outer side of the optical unit that transmits light to the eyeball through the pupil 26. Thereby, the influence which the coloring ring 24 has on vision is suppressed. On the other hand, the outer diameter dimension of the coloring ring 24 can cover the white eye 12 with a predetermined width. Thereby, the cosmetic effect which makes the limbal 16 look large on an external appearance is exhibited.

  In particular, when the colored contact lens 10 is a visual acuity correction contact lens, the visual acuity correction is performed on the central region surrounded by the coloring ring 24 that is located on the inner peripheral side of the coloring ring 24. An optical unit having optical characteristics is provided. And it is desirable to provide the coloring ring 24 with respect to the peripheral part which does not have the correction | amendment optical characteristic to an eye optical system formed in the outer peripheral part which remove | deviated this optical part to the outer peripheral side.

  In addition, the coloring ring 24 may be provided to reach the outermost peripheral edge portion 18 of the colored contact lens 10, but in this embodiment, the outer diameter of the coloring ring 24 is outside the colored contact lens 10. An outer peripheral transparent region 28 is provided as an annular non-colored region extending in the circumferential direction with a predetermined radial width between the colored ring 24 and the edge portion 18 and smaller than the diameter dimension (DIA). Yes.

  Such a colored ring 24 is preferably formed with a width dimension in the radial direction of 0.5 to 3.5 mm in order to sufficiently obtain a desired cosmetic effect or the like. It is formed with a width dimension in the radial direction of 0 to 2.5 mm. The radial width dimension of the coloring ring 24 does not need to be constant over the entire length in the circumferential direction, and the inner peripheral edge shape and the outer peripheral edge shape may be different shapes such as an ellipse other than a circle. It is preferably formed in an annular shape having a constant width dimension on the circumference.

  The inner diameter of the colored ring 24 is preferably φ8.0 mm or more (radius is 4.0 mm or more) in consideration of the pupil diameter or the like, and more preferably in consideration of the pupil diameter expansion. Is φ9.0 mm or more (radius dimension is 4.5 mm or more), more preferably φ10 mm or more (radius dimension is 5.0 mm or more) or φ12 mm or more (radius dimension is 6.0 mm or more).

  On the other hand, considering the size of the cornea of an ordinary person so that the inner peripheral portion of the coloring ring 24 is covered with the black eye 14, the inner diameter dimension of the coloring ring 24 is φ13 mm or less (radius dimension is 6.5 mm or less). It is preferable that In particular, it is natural that a sufficient area of the white eye 12 is left on the outer periphery of the coloring ring 24 when worn, and the beauty of the white eye 12 is effective for the cosmetic effect. The outer diameter of 24 is more preferably φ15 mm or less (radius dimension is 7.5 mm or less). Furthermore, the outer diameter of the coloring ring 24 is preferably φ11 mm or more, and more preferably φ12 mm or more so that the white eye 12 can be covered with a predetermined width.

  Here, the coloring ring 24 is provided with a gradation region in which the light transmittance is not uniform and the density changes. In the present embodiment, the constant color region 30 having a constant light transmittance is formed in an annular shape extending at a predetermined width in the radial direction over the entire circumference in the radial intermediate portion of the coloring ring 24. Yes. An outer peripheral gradation region 32 where the light transmittance of the colored ring 24 gradually decreases toward the outer peripheral side is formed on the outer peripheral side of the constant color region 30 located at the outer peripheral portion of the coloring ring 24. Further, an inner peripheral gradation region 34 in which the light transmittance of the coloring ring 24 gradually decreases toward the inner peripheral side is formed on the inner peripheral side of the constant color region 30 located in the inner peripheral portion of the coloring ring 24. Yes.

Further, it is desirable that the constant color region 30, the outer peripheral gradation region 32, and the inner peripheral gradation region 34 constituting the coloring ring 24 satisfy the following conditions (1) to (4).
(1) Although the constant color region 30 can be substantially not provided, it is formed with a radial width dimension of 0.01 mm or more and 3.5 mm or less in order to sufficiently obtain a desired cosmetic effect. It is desirable that
(2) Since the constant color region 30 is desirably provided at a position overlapping the limbal 16, the constant color region 30 is 4.5 mm to a distance in the radial direction from the lens center in consideration of the size of the cornea of an ordinary person. It is preferable to be formed in an area of 7.0 mm. That is, in FIG. 2, D1 representing the boundary between the constant color region 30 and the inner peripheral gradation region 34 is 4.5 mm or more from the lens geometric center axis 20, and the constant color region 30 from the lens geometric center axis 22. It is desirable that D2 which is the boundary of the outer peripheral gradation region 32 is 7.0 mm or less. This avoids adverse effects on the eye optical system and also prevents the white eye 12 region from becoming too small to feel unnatural.
(3) The radial width dimension of the outer peripheral gradation region 32 is preferably 0.5 mm to 2.5 mm, and more preferably 0.7 mm to 1.5 mm.
(4) The radial width dimension of the inner peripheral gradation region 34 is preferably 0.5 mm to 2.5 mm, and more preferably 0.7 mm to 1.5 mm.

  By providing such a coloring ring 24, it is possible to make the color different from the iris sufficiently visible to the eyes that can be seen from the other person by the constant color region 30 in the wearing state, and the peripheral gradation region 32. In addition, it is possible to obtain a cosmetic effect similar to makeup for the human eye while reducing the artificial and unnatural feeling by the inner peripheral gradation region 34.

  In particular, the outer peripheral gradation region 32 forms a region in which the outer peripheral side of the colored ring 24 is gradationally assimilated with respect to the white eye 12 portion of the eye and is assimilated. Further, the inner peripheral gradation region 34 forms a region in which the inner peripheral side of the coloring ring 24 is gradationally assimilated with respect to the black eye 14 portion of the eye and assimilated. Thereby, when the colored contact lens 10 is worn, an unnatural boundary line is prevented from being conspicuously formed by the inner peripheral edge and the outer peripheral edge of the coloring ring 24 in the black eye 14 portion and the white eye 12 portion of the eye. Is done.

  As a result, wearing the colored contact lens 10 can reduce an unnatural feeling while giving an artificial color different from the iris by the coloring ring 24 as in the case of human eye makeup. In addition, the gradation region in which the gradation is changed from a portion having a high light transmittance to a portion having a low light transmittance can provide a three-dimensional appearance on the appearance as in the case of human eye makeup.

  Therefore, according to the colored contact lens 10 provided with the coloring ring 24 of the present embodiment, “expression of three-dimensional effect”, “blur”, “make familiar”, and “make stand out” that could not be realized conventionally. Thus, a makeup technique using a color having a hue different from the natural color can be applied to the human eye. As a result, the colored contact lens 10 can easily realize a cosmetic effect with a degree of freedom so that the impression desired by the wearer can be held by another person according to the situation and preference.

  In addition, since this colored contact lens 10 employs the same method as that for human eye makeup in the coloring ring 24, the entire face makeup including the eyes is unified in combination with the makeup applied to the human eye. It may be possible to create and apply it. Specifically, for example, by adopting a coloring ring 24 having a hue similar to that of an eye shadow, it is possible to realize a makeup with a sense of unity across both eyes and eyelids.

  The coloring ring 24 can appropriately set the hue, light transmittance, color tone and the like according to the preference and use of the wearer, the iris color, etc., but the target cosmetic effect is more effective. Therefore, in the region where the light transmittance of the coloring ring 24 is the highest (the constant color region 30 in this embodiment), the light transmittance (maximum value) is set within a range of 30% or more and 90% or less. It is desirable that When the maximum value of the light transmittance in the coloring ring 24 is larger than 90%, it becomes easy to give an artificial and unnatural feeling on the appearance in the wearing state. On the other hand, when it is less than 30%, the visibility on the appearance is reduced. There is a possibility that the cosmetic effect will not be fully exerted due to lowering.

  The color of the coloring ring 24 may be different from one or more of the constant color region 30, the outer peripheral gradation region 32, and the inner peripheral gradation region 34, but the entire coloring ring 24 is the same. It is preferable to set the color, that is, the same hue. Thereby, a more natural impression can be given on the appearance, and the colored ring 24 can be easily formed.

  In the coloring ring 24, the constant color region 30, the outer peripheral gradation region 32, and the inner peripheral gradation region 34 are all made constant over the entire circumference without being unevenly distributed in the circumferential direction. It is desirable. Further, it is desirable that the radial width dimensions in the constant color region 30, the outer peripheral gradation region 32, and the inner peripheral gradation region 34 are constant over the entire circumference without locally differing in the circumferential direction. . As a result, the colored contact lens 10 can be easily worn without being positioned in the circumferential direction, and the colored ring 24 can be made more natural in appearance.

  By the way, the formation method of the coloring ring 24 is not limited. For example, as described in JP-A-3-54519, a contact lens molding monomer is cast to form a contact lens. Coloring, hand-drawing, photographic printing, screen printing, etc. are possible, but pad printing or ink-jet printing can be performed in consideration of a spherical surface, mass productivity, coloring accuracy, color reproducibility, etc. Is preferred.

  For pad printing, for example, after filling a dot pattern formed by etching a metal plate with a colorant, the dot pattern colorant is transferred using a silicon pad, and the dot is applied to a contact lens prepared in advance. The colored ring 24 can be formed by transferring the pattern colorant.

  More preferably, ink jet printing is employed. Ink jet printing is a method in which a colorant is blown out from a large number of minute nozzles using a piezo element or the like as an actuator and is directly applied to a colored surface of a contact lens prepared in advance. In such inkjet printing, there is no need to press a pad or the like on the contact lens, and it is possible to form minute dots with high precision, and by adjusting the number of dots of multiple colors and their mutual ratio, It is particularly preferred because it is easy to express as.

  Further, the coloring mode of the coloring ring 24 is not limited, and may be a solid coating mode with a translucent coloring material over the entire surface. However, a translucent or non-translucent colorant is used. Coloring in the form of dots is preferable because the light transmittance, hue, and color tone can be adjusted accurately and easily. In particular, the dot-like coloring can be performed by attaching a colorant containing a dye or a pigment to the front surface and / or the back surface of the contact lens in a small dot shape after molding.

  In addition, in order to clarify the presence of the coloring ring 24 on the appearance and further improve the cosmetic effect, a pigment having high concealability for the iris or the white eye 12 is preferable as the coloring material. As specific colorants, various conventionally known colorants can be appropriately employed without distinguishing between pigments and dyes or distinguishing colors. That is, it is possible to use a coloring material obtained by mixing one or more kinds of appropriate pigments or dyes selected in consideration of the target color and a solvent corresponding thereto, Curing agents, additives, and the like corresponding to the material of the contact lens to be colored and the fixing treatment adopted can be appropriately blended.

  Further, the color adopted for the colorant and hence the colored dot 36 is not limited as described above. In particular, in the present invention, as a measure for adjusting the hue and the like, the size and density (as described above) of the colored dot 36 ( It is also possible to adjust the ratio of each color by adjusting the (interval) or by providing colored dots 36 of different colors. For example, it is possible to express various colors based on the color mixing method by adjusting the proportions of the three primary colors, and it is also possible to add lame used for makeup for the human eye . As a method for attaching the colored dots 36, the above-described ink jet printing is suitable.

  Or what formed the colored dot 36 between the layers of the front surface and back surface of a contact lens can also be used for this invention. As a method for forming the colored dots 36 between the layers, there is a method in which the colored dots 36 are provided on the front or rear half layer and the remaining half layers are adhered. In this way, it is possible to obtain a colored contact lens having a laminated structure in which a transparent layer is provided on each of the front and rear surfaces of the colored layer. As described above, the colored layer is formed as a printed layer, and as described in JP-A-3-54519, a colored resin using a colored molding monomer in which a coloring material is dissolved. It can also be formed as a layer. In addition, although depending on the formation method of the colored layer, the light transmittance of the coloring agent, and the like, when employing a laminated structure composed of at least one colored layer and a transparent layer, the thickness of each transparent layer is set to 5 μm to It is desirable that the thickness of each colored layer is 0.2 μm to 100 μm while the thickness is 300 μm. In particular, when a printing layer by pad printing, ink jet printing, or the like is employed as the colored layer, the layer thickness of the printing layer is preferably set smaller than the transparent layer.

  Further, in the colored ring 24 formed by adhering and fixing the colored dots 36 to the lens by ink jet printing, the size and density (light transmittance) of each colored dot 36 itself is made different so that the diameter can be changed from the inner peripheral side. It is also possible to increase the light transmittance toward the central portion in the direction, and to decrease the light transmittance from the central portion in the radial direction toward the outer peripheral side. On the other hand, in the colored contact lens 10 of the present embodiment shown in FIG. 1, the colored dots 36 having the same density (light transmittance) of each colored dot 36 itself are employed, and the number of the colored dots 36 per unit area. By changing the (density) in accordance with the radial position of the colored contact lens 10, the light transmittance in the outer peripheral gradation region 32 and the inner peripheral gradation region 34 is changed.

  Specifically, in this embodiment, circular colored dots 36 having the same size and shape are employed, and each colored dot 36 itself has the same color and density (light transmittance). . In the constant color region 30, coloring is applied over the entire surface by appropriately setting the interval and size of the colored dots 36. On the other hand, in the outer peripheral gradation area 32 and the inner peripheral gradation area 34, the gradation in the radial direction is realized by changing the density of the colored dots 36 in accordance with the radial position. Specifically, for example, when a plurality of virtual circular arrangement lines extending around the lens geometric center axis 22 are concentrically assumed at regular intervals in the radial direction, and the colored dots 36 are arranged on each of the circular arrangement lines. The spacing between the colored dots 36 is set to be substantially the same in the circumferential direction, but gradually changes in the radial direction. In the outer peripheral gradation area 32, the circumferential interval of the colored dots 36 is reduced from the radially inner side to the radially outer side. Further, in the inner peripheral gradation region 34, the interval in the circumferential direction of the colored dots 36 is reduced from the radially outer side to the radially inner side.

  Note that FIG. 1 is enlarged for easy understanding, and in order to make it easy to image the arrangement of the colored dots 36 on the surface, the interval and size of the colored dots 36 are accurately set. Is not represented. Further, in FIG. 1, a specific color cannot be expressed due to the limitation of the patent drawing. Actually, the colored dots 36 are blue, red, or the like, with the worn iris being black.

  Here, the color employed for the colorant and hence the colored dot 36 is not limited, but in the present invention, the hues of the constant color region 30, the outer peripheral gradation region 32, and the inner peripheral gradation region 32 are different. You may make it. The hue is grasped by the Munsell color system, for example. Specifically, in the Munsell hue circle, a total of five (R, YR, Y, GY, G, BG, B, PB, P, RP) hues are provided in the middle of each of the five basic colors. Are preferred, colors including G or B (GY, G, BG, B, PB) among them are preferred, and these dark colors are more preferred. Alternatively, brown, black, etc. are also preferably employed in the present invention.

  In the colored contact lens 10 according to the first embodiment described above, the gradation regions are provided in the inner peripheral region and the outer peripheral region of the coloring ring 24, respectively. A gradation region may be provided in only one of them.

  Specifically, for example, by setting the outer peripheral gradation region 32 in the first embodiment to the same color and light transmittance as the constant color region 30, as shown in FIG. A region from 24 radial intermediate portions to the outer peripheral edge portion may be the constant color region 30 throughout. Alternatively, the inner peripheral gradation area 34 in the first embodiment also has the same color and light transmittance as the constant-color area 30, so that the radial direction of the coloring ring 24 is as shown in FIG. The region from the intermediate portion to the outer peripheral edge portion may be the constant color region 30 throughout. By making the outer peripheral edge or inner peripheral edge of the constant color region 30 stand out in this way, the coloring ring 24 having a color different from the iris is made conspicuous, while the inner peripheral edge or outer peripheral edge of the constant color region 30 is made familiar. A makeup technique such as blurring becomes possible.

  In addition, it is not essential that the pattern having the gradation region formed with a hue different from the iris according to the present invention is formed in a ring shape surrounding the optical part like the colored ring 24 in the first embodiment. For example, it is possible to form such a pattern so as to be located at one or a plurality of locations on the periphery of the optical part in the outer peripheral part off the optical part. In addition, since it is not necessary to provide a permeable optical part or the like at the center of the pattern, the degree of freedom in designing the pattern such as shape and size is increased.

  Specifically, for example, as shown in FIG. 5, a colored pattern 38 having a solid colored region in which the light transmittance is increased so that the central portion is entirely filled may be employed. Is possible. Thus, in the colored pattern 38 in which the central portion is the constant color region 30 spreading with the maximum light transmittance, the outer peripheral gradation region 32 can be formed in the outer peripheral portion. In this manner, the colored pattern 38 in which the central portion is colored over the entire portion can be made more easily visible and conspicuous as compared with the annular colored ring 24. Therefore, the target cosmetic effect can be obtained more effectively even with the small colored pattern 38.

  Furthermore, even when the colored ring 24 having an annular pattern whose central portion is not colored is employed, it is not necessary to have an annular shape as in the first embodiment, and the incident light to the pupil 26 is not incident. Any ring shape can be employed as long as it is not obstructed. Specifically, for example, as shown in FIG. 6 (a), a star-shaped polygonal ring-shaped coloring ring 24 can be adopted, and also shown in FIGS. 6 (b) and 6 (c). As shown, the star-shaped polygonal ring-shaped coloring ring 24 in which only the inner gradation area 34 is formed as the gradation area, or the star shape in which only the outer gradation area 32 is formed as the gradation area. A polygonal ring-shaped coloring ring 24 or the like can also be employed.

  Further, like the first embodiment, such an arbitrarily colored coloring ring 24 surrounds the outer peripheral portion of the central region such as the optical portion of the contact lens so as to surround the central region located on the pupil 26. By forming the ring shape extending in the direction, a visual field can be secured through the ring-shaped central transparent region. In addition, the colored ring 24 having an arbitrary shape may be provided so that one or a plurality of the colored rings 24 are scattered at positions outside the central region of the contact lens and on the outer peripheral side. When the optical unit is provided at a position off the outer peripheral side, it is possible to employ a solid colored pattern 40 as shown in FIG. 7, for example. The colored pattern 40 in FIG. 7 has an outer peripheral gradation region 32 as in the solid circular colored pattern 38 shown in FIG.

  The hollow colored ring and the solid colored pattern are not limited to the star shape as shown in FIGS. 6 and 7, and can be formed in an arbitrary shape, for example, polygonal shape, heart shape, A clover shape or the like may be employed as appropriate. In addition, multiple transparent areas can be arbitrarily placed in a colored ring or a solid colored pattern in which the outer peripheral shape and inner peripheral shape are different from each other so that the outer peripheral shape is circular and the inner peripheral shape is a star shape. An aspect provided with a shape can also be adopted.

  Further, in FIGS. 8A, 8B, and 8C, as still another embodiment of the present invention, the inner peripheral side straddling the boundary 16 between the black eye 14 and the white eye 12 of the eye to be worn is shown. Colored contact lenses 44, 46, 48 having a ring ring 42 that extends in the outer peripheral side and is an area colored with the same hue as the iris of the eye to be worn are shown.

  The colored contact lens 44 shown in FIG. 8A is formed with a limbal ring 42 that extends in the lens circumferential direction on the same central axis as the lens geometric central axis 22 and spreads in an annular shape. The limbal ring 42 is formed in the same hue as the iris of the wearer's eye, and is provided at a position and shape that covers the limbal 16 (outer peripheral edge of the eye) of the eye. The limbal ring 42 only needs to look the same color on the appearance as the iris of the wearer's eye, and generally has a hue range of ± 30 degrees, more preferably ± 15 degrees. It can be adopted as the same color as the iris. For example, in the case of a black or brown iris, the black or brown limbal ring 42 can be employed as substantially the same color as the iris.

  The limbal ring 42 has substantially circular inner and outer peripheral edges corresponding to the outer peripheral edge shape of the cornea, but is not only a perfect circle but also an ellipse or the like that does not give a great discomfort to the appearance. It may be. Furthermore, the inner diameter and outer diameter of the limbal ring 42 are formed with an inner diameter smaller than the outer cornea of the eye to be worn and an outer diameter larger than the outer cornea of the eye to be worn. The inner diameter and the outer diameter are φ14 mm or less. If the inner diameter dimension is smaller than φ8 mm, the limbal ring 42 may reach the pupil 26 and adversely affect the vision. If the outer diameter dimension is larger than φ14 mm, the white eye 12 region located on the outer peripheral side of the limbal ring 42. May become too small and give a sense of incongruity.

  The limbal ring 42 is formed simultaneously with the molding of the contact lens by using a colored molding monomer, or by hand-drawing, photographic printing, screen printing, pad printing, ink-jet, etc. It can be formed by any method such as printing. In addition to coloring the entire surface in a solid coating state, it is also possible to form the limbal ring 42 with the colored dots 36.

  By providing a limbal ring 42 of the same color as the iris like this, it becomes possible to make the black eye 14 appear large while keeping the color of the black eye 14 natural, and a cosmetic that gives a natural and friendly cute impression An effect can be obtained.

  In the colored contact lens 44 of FIG. 8A, the inner and outer peripheral edges of the limbal ring 42 are both formed with clear lines, as shown in FIG. 8B. In addition, a transition region 50 in which the light transmittance gradually decreases as it goes inward in the radial direction with respect to the inner peripheral edge of the limbal ring 42 may be provided. Further, as shown in FIG. 8C, a transition region 52 that gradually decreases in light transmittance as it goes radially outward may be provided on the outer peripheral edge of the limbal ring 42.

  By providing such transition regions 50 and 52, the appearance of the colored contact lens 46 (48) is clearly visible on the iris and the white eye 12 due to the inner and outer peripheral edges of the limbal ring 42. The generation of a line can be avoided. As a result, the limbal ring 42 allows a large corneal region to be imparted to the wearer's eye with a more natural and human appearance.

  In addition, in addition to the limbal ring 42 having the same color as the iris, the colored contact lenses 44, 46, and 48 shown in FIGS. According to the present invention, a coloring ring 54 is provided which is a pattern of a different color from the iris.

  Such a colored ring 54 is colored differently from the iris in the same manner as the colored ring 24 shown in FIGS. 1, 4, and 6, so that even if it is provided on the region of the limbal ring 42, The colored ring 54 is clearly visible on the appearance. Further, in the limbal ring 42 shown in FIGS. 8B and 8C, similarly to the colored ring 24 shown in FIGS. In addition, at least one of the transition region 50 and the transition region 52 is formed in at least one of the inner peripheral portion and the outer peripheral portion. In each of the colored rings 54 shown in FIGS. 8A, 8B, and 8C, the outer peripheral gradation region 32 is provided as shown in the enlarged detail view of the main part. .

  Thus, by providing the coloring ring 54 in addition to the limbal ring 42, it is possible to obtain the cosmetic effect by the coloring ring 54 in addition to the effect of expanding the pupil diameter on the appearance by the limbal ring 42. In particular, by providing the colored ring 54 over the limbal ring 42, an effect of making the color of the colored ring 54 more conspicuous by the color applied to the limbal ring 42 can be expected.

  By the way, instead of the colored ring 54 as the pattern shown in FIGS. 8A, 8B, and 8C, for example, a solid as shown in FIG. 5 or FIG. It is also possible to adopt a colored pattern of the shape.

  Further, even when such a colored ring 54 or a colored pattern is used in combination with a limbal ring 42 of the same color as the iris, the colored pattern is formed at a position off the inner peripheral side or the outer peripheral side from the limbal ring 42. It is also possible to attach. The aspect is illustrated in FIGS.

  In the colored contact lens 56 shown in FIG. 9, colored rings 58 and 60 that are partially located on the circumference in each of a region outside the limbal ring 42 and a region outside the outer circumferential side. Is provided. It is possible to form a plurality of colored rings 58 and 60 at equal intervals on the circumference of the colored contact lens 56. However, one or a plurality of colored rings 58 and 60 are unevenly distributed on the circumference as illustrated. In this case, it is also possible to set the positions of the coloring rings 58 and 60 under the wearing state by a known circumferential positioning means such as prism ballast or double thin. In addition, the outer peripheral gradation area | region 32 is provided in each outer peripheral side of the coloring rings 58 and 60 in this embodiment.

  Further, in the colored contact lens 62 shown in FIG. 10, a colored ring 64 is provided on the inner peripheral side of the limbal ring 42. The coloring ring 64 has the same structure as that of the embodiment shown in FIG. 1 and has an annular shape in the circumferential direction along the inner peripheral edge of the limbal ring 42 on the same central axis as the limbal ring 42. It extends to.

  Furthermore, in the colored contact lens 66 shown in FIG. 11, a colored ring 68 is provided on the outer peripheral side of the limbal ring 42. The coloring ring 68 has a structure similar to that of the embodiment shown in FIG. 1 and has an annular shape in the circumferential direction along the outer peripheral edge of the limbal ring 42 on the same central axis as the limbal ring 42. It extends to.

  Further, the outer peripheral gradation region 32 and the inner peripheral gradation region 34 are formed in the coloring rings 64 and 68 shown in FIGS. 10 and 11. In the colored contact lens 62 of FIG. 10, the outer peripheral gradation region 32 of the coloring ring 64 is formed in a region that overlaps the limbal ring 42, and the rim ring 42 moves from the inner peripheral edge to the outer peripheral side. It is formed so as to extend into the bull ring 42 and expand. On the other hand, in the colored contact lens 66 of FIG. 11, the limbal ring 42 includes a constant color region 30 and a transition region 52 on the outer peripheral side, and a coloring ring 68 is provided further on the outer peripheral side of the transition region 52 on the outer peripheral side. It has been. In short, the inner peripheral gradation region 34 of the coloring ring 68 is provided on the outer peripheral side of the transition region 52 on the outer peripheral side of the limbal ring 42.

  In the colored contact lens 62 shown in FIG. 10, the colored ring 64 can be positioned on the iris on the inner peripheral side of the limbal ring 42 positioned on the outer peripheral edge of the cornea in the worn state. ing. On the other hand, in the colored contact lens 66 shown in FIG. 11, the colored ring 68 is positioned on the white eye 12 on the inner peripheral side of the limbal ring 42 located on the outer peripheral edge of the cornea in the worn state. It has become.

  Furthermore, a colored contact lens 69 according to another embodiment of the present invention is shown in FIG. In the present embodiment, the iris pattern 70 is colored and formed in a region located on the inner peripheral side of the pattern 20. The colored ring 24 shown in FIG. 1 is used for the pattern 20 shown in FIG.

  The iris pattern 70 is formed on the inner peripheral area of the pattern 20 (coloring ring 24), that is, on the iris of the human eye. The shape of the iris pattern 70 is not limited to that shown in the figure, and is composed of a plurality of colored dots 71 in FIG. 12, but in addition to the colored dots 71, polygons, line segments, etc. The density, size, light transmittance, and the like can be arbitrarily set. Further, it is preferable that the iris pattern 70, that is, the colored dots 71, is not formed on the pupil 26 as much as possible from the viewpoint of the wearer's field of view, or the light transmittance is reduced on the pupil 26 as much as possible. Further, as for the coloring method of the iris pattern 70 (colored dots 71), a known printing method can be adopted in the same manner as the coloring ring 24, but inkjet printing and pad printing are particularly preferable. Further, the hue of the iris pattern 70 (colored dots 71) is not particularly limited as in the colored ring 24, and the hue of the iris pattern 70 (colored dots 71) and the hue of the colored ring 24 are the same. It is possible to make things different.

  Then, by wearing the colored contact lens 69, when the third person visually recognizes the wearer, the hue of the iris of the wearer on which the hue of the iris pattern 70 is superimposed is recognized. For example, by making the hue of the iris pattern 70 (colored dots 71) substantially the same as the hue of the wearer's iris, it is possible to give the impression that the pupil is very three-dimensional and deep. It is possible to make it difficult to give the impression that the colored contact lens 69 is attached. Alternatively, by making the hue of the iris pattern 70 (colored dot 71) significantly different from the hue of the wearer, it becomes easier for a third party to recognize the hue of the iris different from the original hue of the wearer, and the colored contact This makes it easier to give an impression different from that before the lens 69 is mounted. Furthermore, by making the hue substantially the same as that of the colored ring 24 described above, the cosmetic effect that the boundary line where the hue changes is not clarified while the hue of the iris is changed is sufficiently exhibited.

  Examples of the present invention will be shown below for reference. First, as shown in FIG. 13A, the colored contact lens 72 having a structure in which the coloring ring 24 is provided on the outer periphery of the limbal ring 42 as in the embodiment shown in FIG. Fig. 13B and Fig. 13C are imaging diagrams showing a state worn on the human eye (a contact lens superimposed on a human eye photograph by CG). In addition, although there are restrictions on the patent drawing, it is a monotone drawing. FIGS. 13 (b) and 13 (c) are pink, considering the harmony with the color of the eye shadow applied to the eyelid. The colored ring (b) and the blue colored ring (c) are shown.

  Further, as shown in FIG. 14A, in addition to the limbal ring 42 in which the transition region 50 is formed on the inner peripheral side as shown in FIG. An imaging diagram showing a state in which a colored contact lens 74 having a structure in which a colored ring 24 extending in a circumferential direction is provided in a radial intermediate portion of the ring 42 is actually worn on the human eye (a contact lens is attached to a human eye photograph by CG). FIGS. 14 (b) and 14 (c) show the superposition). FIGS. 14B and 14C also use a pink colored ring (b) and a blue colored ring (c) in consideration of harmony with the color of the eye shadow applied to the eyelid. This shows the state. Further, the coloring ring 24 has a structure in which an outer peripheral gradation region 32 and an inner peripheral gradation region 34 are provided with respect to the annular shaped constant color region 30 provided in the intermediate portion in the radial direction.

  In FIGS. 13 and 14, since the wearing state is represented by monotone, it is difficult to clearly recognize the cosmetic effect exhibited while maintaining the natural or soft impression exhibited by the present invention. It can be seen or easily imagined that the cosmetic effect can be given to the eye and the degree of mutual harmony with the eye shadow can be achieved.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the specific descriptions in the embodiments, and various changes, modifications, improvements, and the like based on the knowledge of those skilled in the art. It is feasible in the form which added.

  For example, while using a plurality of colored contact lenses according to any one of the above embodiments, each colored contact lens is provided with a pattern 20 having the same or different shape, and the hue of the pattern 20 is set to the hue of the eye shadow. A plurality of corresponding colors may be set for each pattern, and a plurality of types of colored contact lenses having the plurality of patterns 20 may be combined to form a colored contact lens set. As shown in FIGS. 13 and 14, it is possible to exert a further cosmetic effect by the interaction between the eye shadow and the colored contact lens, but the eye shadow of the same hue is always used. Rather, it is common to use eye shadows in different moods and atmospheres, or in formal or casual places. In such a case, a further cosmetic effect can be exhibited by appropriately selecting the color combination of the eye shadow and the pattern 20. For this reason, a colored contact lens set including a plurality of colored contact lenses having a plurality of colored patterns 20 corresponding to the hue of the eye shadow is preferably employed. The hue of the eye shadow associated with the pattern 20 can be arbitrarily set. For example, for a specific eye shadow product, the hue of the pattern 20 is set with respect to the hue used for the eye shadow product. It is good also as an associated colored contact lens set.

  In the above-described embodiment, it has been described that a further cosmetic effect can be obtained by making the hues of the colored ring 24 and the iris pattern 70 (colored dots 71) the same or different. It is considered that adding an eye shadow to the pattern 70 (colored dots 71) is one of the elements that can provide a cosmetic effect. At that time, it is possible to enjoy fashion by aligning the hues of the coloring ring 24, the iris pattern 70 (colored dots 71), and the eye shadow with similar colors, or by making any one or each hue different. It is.
