Description

{Beauty contact lens and manufacturing method thereof}

The present invention relates to cosmetic contact lenses and a method for manufacturing the same, and more specifically, to a method for enabling an image formed on cosmetic lenses, such as circle lenses, colored lenses, and piercing lenses, worn for cosmetic purposes, to be converted into different images depending on the situation.

In particular, the present invention relates to a cosmetic contact lens and a method for manufacturing the same, which can satisfy both consumer needs for design when purchasing and consumer needs for design when wearing by making the color image appear as different images when not being worn and the color image appearing when wearing.

Contact lenses are used to correct the wearer's eyesight and are worn on the cornea and inserted inside the eyelid. Recently, in addition to correcting eyesight, lenses for cosmetic purposes such as circle lenses that make the eyes look bigger, colored lenses with various images, and piercing lenses with various shapes such as stars or hearts (hereinafter referred to as "cosmetic lenses") are also being commercialized and sold.

In this way, cosmetic contact lenses worn for aesthetic enhancement are manufactured by printing various colored images on a transparent lens body. As shown in the prior art document, Republic of Korea Patent Publication No. 10-2145423 entitled “Method for Manufacturing Contact Lenses Using Inkjet” (hereinafter referred to as “Prior Art 1”), the image is printed using a transfer method using a pad.

In addition, the image formed on the cosmetic lens is divided into a transparent coloring method and an opaque coloring method. The cosmetic lens with a transparent coloring method is mainly used to block ultraviolet rays, etc. while emphasizing transparency, and the cosmetic lens with an opaque coloring method is mainly used to change the color of the iris to enhance the aesthetic sense.

These cosmetic lenses have been mainly developed based on technologies related to methods or techniques for printing images, such as the previously described prior art 1 or the prior art document below, Republic of Korea Patent Publication No. 10-2123097 entitled “Laser engraving jig for printing color contact lenses” (hereinafter referred to as “prior art 2”).

In other words, most of the conventional technologies, such as prior art 1 or prior art 2, are technologies regarding the products themselves or the manufacturing methods of the products, and it can be seen that most technologies related to cosmetic lenses to date have been developed with a focus on the products, and technologies centered on consumer needs have been limited to methods of forming fragmentary images, such as simply what kind of design to form.

Korean Patent Publication No. 10-2145423 'Method for manufacturing contact lenses using inkjet' Korean Patent Publication No. 10-2123097 'Laser engraving jig for printing color contact lenses'

In order to solve the above problems, the present invention aims to provide cosmetic contact lenses, in which an image formed on cosmetic lenses, such as circle lenses, color lenses, and piercing lenses, worn for cosmetic purposes, can be converted into different images depending on the situation, and a method for manufacturing the same.

In particular, the present invention aims to provide a cosmetic contact lens and a method for manufacturing the same, which can satisfy both consumer needs for design when purchasing and consumer needs for design when wearing, by making the color image appear as different images when not being worn and the color image appearing when wearing.

In addition, the present invention aims to provide cosmetic contact lenses and a method for manufacturing the same, which can express a product logo (emblem) or a brand image that identifies a specific product when not being worn, and express an image requested by a consumer when being worn, thereby satisfying the needs of consumers and increasing the value of a company's name value and achieving product sophistication and branding.

In order to achieve the above purpose, a cosmetic contact lens according to the present invention comprises: a lens body formed to be wearable on the cornea; and an image layer formed to be disposed on at least a portion of one side of the lens body and to show a color image when not worn and to show a colored image when worn.

In addition, the image layer may be divided into at least two image areas, and each image area may include at least one of a base layer; and an image expression layer in which color is expressed.

Additionally, the base layer may be formed in an achromatic color, and the image expression layer may be formed in a chromatic color.

In addition, the image area may further include a saturation control layer that controls the saturation of the image expression layer.

Additionally, the saturation control layer can be formed in an achromatic color.

In addition, it may further include a protective layer laminated on the image layer.

In addition, the image layer may include a first image region including a base layer disposed on at least a portion of the lens body and formed to reflect incident light; an image expression layer laminated on at least a portion of the base layer and reflecting at least a portion of the incident light and expressing a color; and a second image region including an image expression layer disposed on at least another portion of the lens body and reflecting at least a portion of the incident light and expressing a color.

In addition, at least a part of the color image can be expressed by a base layer formed to reflect incident light and disposed on at least a part of the lens body; and an image expression layer laminated on at least a part of the base layer and reflecting at least a part of the incident light and expressing a color.

Additionally, at least a part of the color image may be expressed by an image expression layer that is arranged on at least another part of the lens body and reflects at least a part of incident light and expresses color.

In addition, the image expression layer may further include a saturation control layer formed to control the saturation of the image and laminated on at least a portion of the image expression layer.

In addition, a method for manufacturing a cosmetic contact lens according to the present invention comprises the steps of: preparing an upper mold and a lower mold; printing a base layer on the upper mold or the lower mold; printing an image expression layer by laminating it on the base layer; injecting a chemical solution into the mold on which the base layer and the image expression layer are printed; combining the upper mold and the lower mold and curing the chemical solution; and separating the upper mold and the lower mold to extract a lens body having an image layer including a base layer and an image expression layer inserted; wherein the step of printing the image expression layer comprises: performing dot printing by using a predetermined primary color ink to print a predetermined dot group, performing dot printing multiple times as many times as the number of primary colors used.

In addition, between the step of printing the image expression layer and the step of injecting the drug, the method may further include a step of printing a saturation control layer for controlling the saturation of the image expression layer.

In addition, the method may further include a step of forming a protective layer laminated on the image expression layer or the saturation control layer between the step of printing the image expression layer and the step of injecting the chemical solution, or between the step of printing the saturation control layer and the step of injecting the chemical solution.

By the above-described solution, the present invention has an advantage in that an image formed on a cosmetic lens, such as a circle lens, a color lens, or a piercing lens, worn for cosmetic purposes can be converted into a different image depending on the situation.

More specifically, the present invention has an advantage in that it can make the color image appearing in a non-wearing state and the color image appearing in a wearing state appear as different images.

Through this, the present invention has the advantage of being able to satisfy various consumer needs, such as consumer needs for design when purchasing and consumer needs for design when wearing.

For example, the present invention has the effect of satisfying both the consumer's need to express a vivid image in color before wearing and the consumer's need to express a natural image in color development after wearing.

Meanwhile, when forming an image on a contact lens, when forming a desired image by mixing ink, the color may differ depending on the mixing or viscosity of the mixed inks, making it difficult to form the same image.

Accordingly, the present invention has the advantage of being able to accurately and consistently implement a desired image or color by matching primary colors for each dot and dot group (a set of dots) based on the dot printing method when implementing an image, and making at least a portion of the distribution of each dot group overlap, thereby improving the printing quality and uniformity of a product.

In addition, the present invention has the advantage of enabling the supply, storage and management of ink used in printing in its original color state rather than in a state of mixing the primary colors, thereby facilitating the supply and management of raw materials, and thereby enabling efficient process management of the printing process.

In addition, the present invention has the advantage of enabling consumers to easily select a product of a specific company or to appeal to others that they have purchased a product of a specific company by displaying a logo (emblem) or the like indicating that the product is from a specific company when the product is displayed.

In addition, the present invention has the advantage of achieving product sophistication and branding by allowing a product-specific brand image to be expressed that identifies a specific product among the products sold by the company along with the company logo.

In other words, the present invention has the advantage of satisfying consumer needs, increasing the value of the company's name value, and making the product more luxurious and brandable by allowing the company's logo or product brand to be expressed when not being worn and allowing the image desired by the consumer to be expressed when worn.

In addition, the present invention has the advantage of being able to be utilized for marketing and promotion of companies or products by allowing the company logo or product brand to be expressed in an unworn state, and also greatly improving the effect.

Therefore, it can enhance reliability and competitiveness in the contact lens field, especially in the cosmetic lens field, marketing and promotion of companies and products, as well as in similar or related fields.

Examples of cosmetic contact lenses and their manufacturing methods according to the present invention can be applied in various ways, and the most preferred embodiments will be described below with reference to the attached drawings.

First, the cosmetic contact lens of the present invention (hereinafter, interchangeably used as a 'cosmetic lens') is formed in a curved shape as shown in FIG. 1, and in FIGS. 3, 4, 6, 8, and 10 to be described below, each configuration is expressed in a flat shape so that the technical features can be intuitively and clearly understood, but it is preferable to understand that the actual product is formed in a curved shape.

Figure 1 is a schematic diagram showing one embodiment of a cosmetic contact lens according to the present invention.

Referring to FIG. 1, the cosmetic lens (A) includes a lens body (100) and an image layer (200).

The lens body (100) is formed so that it can be worn on the user's cornea, and can be formed into a curved shape corresponding to the shape of the cornea and can be composed of a transparent material.

The image layer (200) is arranged on at least a portion of one side (the protruding side in FIG. 1, the inner side opposite to it in FIG. 9) of the lens body (100), and can be formed so that a color image is visible when not worn and a color image is visible when worn.

For example, a color image can be formed as shown in (a) of Fig. 11, and can be expressed based on the color of the lens case (white in Fig. 11) as a reference (background).

As another example, the color image can be formed as shown in (b) of Fig. 11, and can be expressed based on the color of the iris (black in Fig. 11) as a reference (background).

In this way, when the color image and the color development image are formed to change depending on the background, the image when the product is displayed for sale or stored in a lens case and the image when the product is worn by a user are different from each other, so that both the consumer's needs for design when purchasing and the consumer's needs for design when wearing can be satisfied.

In addition, if the logo of the company selling the product, the brand image of the product, the serial number of the product (for example, if the color image changes depending on the serial number), etc. are displayed as part of the color image, and when worn, the logo, brand image, or serial number disappears to express the image desired by the consumer, the consumer can easily check the company or product when purchasing the product and purchase it, which can improve the reliability of the product, and since the image they want can be expressed when wearing it, the satisfaction with use can also be improved.

We will look at these features in more detail below.

Figure 2 is a drawing explaining the function of Figure 1.

Referring to (a) of Fig. 2, the image layer (200) can be divided into a first image area (201) and a second image area (202). Of course, it can also be divided into three areas as in (b) of Fig. 5, and it is obvious that it can be divided into more areas if necessary.

And, in the first image area (201), the color image and the chromatic image can be expressed identically, and in the second image area (202), the color image and the chromatic image can be expressed differently.

As a result, as shown in (b) of FIG. 2, the color image (200a) of the image layer (200) can be formed to include at least one image area (the first image area in FIG. 2) among the divided image areas, and the color image (200b) can be formed to include at least another image area (the second image area in FIG. 2) among the divided image areas, as shown in (c) of FIG. 2.

In other words, the color image (200a) can be formed to appear as the same image as the color image (200b) in at least some areas (the first image area in FIG. 2), and can be formed to appear as a different image from the color image (200b) in at least some other areas (the second image area in FIG. 2).

Below, we will examine specifically how the color image (200a) and the color image (200b) are expressed as different images and converted into each other.

FIG. 3 is a drawing showing specific examples of the image layer shown in FIG. 1.

Referring to (a) of FIG. 3, the image layer (200) may include a base layer (210) and an image expression layer (220).

In (a) of Fig. 3, a portion of the light is reflected from the image expression layer (220) and the remaining portion is reflected from the base layer (210), and the image layer (200) can be formed so that the incident light cannot pass through the base layer (210). For example, the base layer (210) can be formed in an achromatic color (e.g., white), and the image expression layer (220) can be formed in a chromatic color (color).

At this time, the white color of the base layer (210) reflects all wavelengths of light (visible light), and the image expression layer (220) reflects only the wavelengths of the corresponding color, so the image expression layer (220) with the base layer (210) as the background becomes visible.

As a result, (a) of Fig. 3 shows that an image of the same color can be expressed regardless of the background positioned in the direction of the bottom surface of the lens body (100).

Here, the image expression layer (220) is a layer that expresses a color image, and can be formed by a dot printing method using uncolored primary color ink. The method of forming the image expression layer (220) will be described in more detail below.

Referring to (b) of Fig. 3, the image layer (200) may include only an image expression layer (220).

In this case, some of the light may be reflected from the image expression layer (220) and the remaining part may pass through the lens body (100) and be reflected from the rear thereof. For example, the image expression layer (220) may be formed of chromatic color.

As a result, (b) of Fig. 3 shows that the color formed in the image expression layer (220) can be expressed as an image of a different color by being influenced by the color of the background in the direction of the bottom surface of the lens body (100).

When this is applied to FIG. 2, at least a part of the color image (200a) can be expressed by a base layer (210) formed to reflect incident light and laminated on at least a part of the lens body (100) as shown in (a) of FIG. 3, and an image expression layer (220) laminated on at least a part of the base layer (210) and reflecting at least a part of the incident light and expressing a color tone.

In addition, at least a part of the color image (200b) may be expressed by an image expression layer (200) that is laminated on at least another part of the lens body (100) as shown in (b) of FIG. 3 and reflects at least a part of the incident light and expresses color.

Accordingly, the first image area (201) configured as in (a) of FIG. 3 can express the color image (200a) and the chromatic image (200b) in the same manner as shown in FIG. 2, and the second image area (202) configured as in (b) of FIG. 3 can express the color image (200a) and the chromatic image (200b) differently as shown in FIG. 2.

In addition, as shown in FIG. 6, the image layer (200) may further include a saturation control layer (230) formed to control the saturation of the image and laminated on at least a portion of the image expression layer (220).

Figure 4 is a drawing explaining an image layer to which the function of Figure 2 is applied.

Referring to FIG. 4, the configuration shown in FIG. 3 can be configured by region shown in FIG. 2. For example, in FIG. 4, the left side of each drawing corresponds to (a) of FIG. 3, indicating a first image region (201), and the right side corresponds to (b) of FIG. 3, indicating a second image region (202).

Accordingly, the first image area (201) can be formed by stacking a base layer (210) and an image expression layer (220), and the second image area (202) can be formed by stacking an image expression layer (220).

Figure 4 (a) shows a state before wearing the cosmetic lens (A), mainly in which the cosmetic lens (A) is stored or displayed in a lens case (10). At this time, the color of the lens case (10) can be formed to be the same color as the base layer (210) (for example, white).

Accordingly, the first image area (201) on the left side shows a color that is a mixture of white (W) reflected from the base layer (210) and color (C) reflected from the image expression layer (220), and the second image area (202) on the right side shows a color that is a mixture of color (C) reflected from the image expression layer (220) and white (W) reflected from the lens case (10). In this state, the images shown in the first image area (201) and the second image area (202) are color images (200a).

And, (b) of Fig. 4 is a state in which a cosmetic lens (A) is worn, and at this time, the color of the iris (30) can be formed in a different color (e.g., black) than the base layer (210).

Accordingly, the first image area (201) on the left side shows a color that is a mixture of white (W) reflected from the base layer (210) and color (C) reflected from the image expression layer (220), and the second image area (202) on the right side shows a color that is a mixture of color (C) reflected from the image expression layer (220) and black (B) reflected from the iris (30) through the cornea (20). In this state, the images shown in the first image area (201) and the second image area (202) are color images (200b).

As a result, the color image (200a) can be formed so that the second image area (202) together with the first image area (201) can be seen with the same color as the base layer (210) as the background, and the color image (200b) can be formed so that the second image area (202) together with the first image area (201) can be seen with the different color as the background (iris of the eye) from the base layer (210), and due to these technical features, the color image (200a) when not worn can be converted into the color image (200b) when worn.

Figure 5 is a drawing explaining embodiments of Figure 2.

Referring to (a) of FIG. 5, the image layer (200) of the cosmetic lens (A) can be divided into a first image area (201) and a second image area (202).

In addition, referring to (b) of FIG. 5, the image layer (200) of the cosmetic lens (A) can be divided into a first image area (201) to a third image area (203).

In addition, the image layer (200) of the cosmetic lens (A) can be divided into a larger number of image areas, and the shapes thereof can also be divided into various shapes other than those shown in FIG. 5, and each image area is not necessarily limited to being connected and divided into one, but can also be separated into two or more areas.

In addition, the image layer (200) of each image area can be expressed in the form of dots and can be formed by printing and transferring by spraying using an inkjet method. Of course, it is obvious that it can be formed in various other ways.

Figure 6 is a drawing showing other embodiments of Figure 3.

Referring to FIG. 6, the image layer (200) may further include an achromatic saturation control layer (230).

For example, at least one of the color image and the chromatic image may be formed to further include a saturation control layer (230), and the saturation control layer (230) may be formed of a translucent material that allows at least a portion of light to pass through and may be formed in an achromatic black or gray color.

Specifically, when the image layer (200) is formed by stacking the base layer (210) and the image expression layer (220) as in (a) of Fig. 6, a saturation control layer (230) may be stacked on top of the image expression layer (220). In this case, as described above, the colors of the base layer (210) and the image expression layer (220) may be mixed and expressed as a color with adjusted saturation.

In addition, even in the case where the image layer (200) is composed of only the image expression layer (220) as in (b) of Fig. 6, a saturation control layer (230) may be laminated on top of the image expression layer (220). In this case, as described above, the color of the image expression layer (220) and the color of the lens case (10) or the iris (30) may be mixed and then expressed as a color with saturation control.

In addition, as shown in (b) of Fig. 6, only the saturation control layer (230) may be laminated on the lens body (100) except for the base layer (210) and the image expression layer (220). In this case, the color of the lens case (10) or the iris (30) may be expressed as a color with saturation control.

In other words, the image layer (200) can be divided into at least two image areas, and each image area can be formed to include at least one of a base layer (210), an image expression layer (220) in which color is expressed, and a saturation control layer (230) that controls the saturation of the image.

FIG. 7 is a schematic diagram showing another embodiment of FIG. 1, and FIG. 8 is a diagram showing specific embodiments of the image layer shown in FIG. 7.

Referring to FIG. 7, the cosmetic lens (A) may further have a protective layer (300) laminated on top of the image layer (200).

This protective layer (300) can protect the image layer (200) from external factors and, at the same time, can protect the area around the eye, such as the inner side of the eyelid, from damage caused by the image layer (200) when wearing the cosmetic lens (A). Here, it goes without saying that the material of the protective layer (300) can be the same as or similar to that of the lens body (100).

FIG. 9 is a schematic diagram showing another embodiment of FIG. 1, and FIG. 10 is a diagram showing specific embodiments of the image layer shown in FIG. 9.

Referring to FIG. 9, the image layer (200) may be formed on the inner surface (lower surface in FIG. 9) of the lens body (100), and the protective layer (300) may be configured to be laminated on the lower surface.

This structure has a stacking order opposite to that of the structure examined previously in Fig. 7, and this may vary depending on the mold used to manufacture the cosmetic lens (A) and the printing direction.

For example, a cosmetic lens (A) can be manufactured using two molds, and among the two molds, the lower mold has a groove formed and the upper mold has a protrusion formed. When the upper mold is joined to the lower mold, a space corresponding to the lens body (100) is formed between the groove and the protrusion.

Looking at the process of making a cosmetic lens (A) using such a mold, as seen above, first, an image printed as a dot image using a pad is transferred to one side of the mold.

Afterwards, a liquid is injected into the groove of the lower mold, the two molds are combined, and when the injected liquid is hardened, a lens body (100) with an image layer (200) inserted can be molded.

At this time, when a lens is manufactured by transferring an image to the protrusion of the upper mold among the two molds, the lens body (100) is formed with the image transferred to the protrusion of the upper mold, so it can be formed in a shape as shown in Fig. 9, and can be manufactured in a form in which the image is inserted into the lens body (100).

Conversely, when a lens is manufactured by transferring an image to the groove of the lower mold among the two molds, the lens body (100) is formed on top of the image transferred to the groove of the lower mold, so it can be formed in a shape like that of Fig. 7, and similarly, it can be manufactured in a shape in which the image is inserted into the lens body (100).

In other words, changes in the structure such as those in Fig. 7 or Fig. 9 vary depending on the method of manufacturing the cosmetic lens (A), and are not limited to a specific one. In addition, it goes without saying that the cosmetic lens (A) can be changed into various shapes or structures depending on the method of manufacturing the cosmetic lens (A).

Additionally, by making the dot size smaller when printing and transferring the image, it is possible to express the image in more detail.

FIG. 12 is a flow chart showing one embodiment of a method for manufacturing a cosmetic contact lens according to the present invention, FIG. 13 is a flow chart showing one specific embodiment of step 'S300' of FIG. 12, and FIG. 14 is a flow chart showing another embodiment of FIG. 1.

First, the image expression layer (220) described above is a layer that expresses a color image, and can be formed using a dot printing method, and in particular, can be printed in a dot shape using uncolored primary color ink.

More specifically, according to the color image (200a) and the color image (200b) to be expressed on the lens, the image expression layer (220) can be formed by performing dot printing for printing a predetermined dot group with a predetermined primary color as many as the required number of primary colors. Here, the dot group refers to a set that includes at least one dot printed with the same primary color.

At this time, the color image (200a) and the color image (200b) implemented by the image expression layer (220) can be formed as at least some of the areas of the dot groups of multiple dot printing overlap each other.

This method of printing by overlapping primary color inks allows for easier control of the printing process and enables consistent printing, compared to printing using a mixing method where color tones, etc. vary depending on the mixing or viscosity of the inks, so it can improve the printing quality and uniformity of the product.

Referring to FIG. 12, the process of manufacturing the cosmetic lens (A) of the present invention to which the above method is applied is examined. First, two molds consisting of an upper mold and a lower mold are prepared (S100), and then one of the two molds (e.g., the lower mold) is selected.

Then, the base layer (210) is printed with achromatic ink on at least a part of the image printing area of the selected mold (S200). Here, the image printing area is an area corresponding to the image layer (200) of the cosmetic lens (A) molded by the mold.

Next, the image expression layer (220) is printed by performing dot printing using primary color inks of a predetermined color to print a predetermined dot group as many times as the number of primary colors used (S300). Here, the area of the dot group of each dot printing may be different from each other.

At this time, dot groups of multiple dot printing may or may not overlap each other, and accordingly, in the image expression layer (220), an area where dot groups do not overlap and are expressed in primary colors and an area where dot groups overlap and are expressed in overlapping colors may be formed.

Looking at this more specifically, as shown in Fig. 13, the image to be printed is confirmed (S310), the primary colors constituting the image are confirmed (S320), and then the dot group on which the color is to be printed is confirmed (S330).

Afterwards, printing is performed on a group of dots on which the corresponding color is to be printed using one color (S340).

If there are additional colors to be printed (S350), dot printing is performed for the additional colors to be printed (S340), and if there are no more additional colors to be printed (S350), printing for the corresponding image can be completed (S360).

Through this process, when printing of all colors for the corresponding image printing area is completed, a saturation control layer (230) for controlling the saturation of the image expression layer (220) may be printed (S350) or a protective layer (300) may be formed (S360) as necessary, as shown in FIG. 14.

Then, when all printing processes for the image layer (200) are completed, the liquid is injected into the groove of the lower mold (S400), and the two molds are combined. When the injected liquid is hardened (S500), the lens body (100) with the image layer (200) inserted can be molded (S600).

The cosmetic contact lens and the manufacturing method thereof according to the present invention have been described above. It will be understood by those skilled in the art that the technical configuration of the present invention can be implemented in other specific forms without changing the technical idea or essential features of the present invention.

Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
