Description

Technical Field

[0001] This invention relates to the field of colored contact lens processing technology, specifically to a method and system for processing full-page images and text on colored contact lenses. Background Technology

[0002] With the rapid development of the colored contact lens industry, consumers' demands for the aesthetics of colored contact lenses are constantly increasing. Full-print graphic colored contact lenses, due to their rich visual effects, have gradually become mainstream products in the market. The core requirement for full-print graphic colored contact lenses is that the images and text perfectly adhere to the lens base, and that they present a clear, uniform, and natural color rendering effect during wear. This places high demands on the processing technology of full-print graphics. Currently, the processing of full-print graphics in colored contact lenses mostly uses a combination of manual methods and simple image processing tools. First, the image and text materials are simply cropped and scaled, and then the adaptation relationship between the images and text and the lens base is manually adjusted. The entire processing relies on the operator's experience, which is not only inefficient and unable to meet the needs of mass production, but also prone to problems such as irregular image and text adhesion and loss of detail.

[0003] In existing technologies, some image processing methods are not specifically adapted to the characteristics of colored contact lens substrates, and only use general image scaling and adaptation methods. This fails to take into account the curvature, light transmittance, and other characteristics of the colored contact lens substrate, resulting in problems such as color distortion, blurred edges, and adhesion wrinkles after the generated full-page images and text are worn, seriously affecting the product's aesthetics and wearing experience. At the same time, existing processing methods lack a comprehensive testing and iterative adjustment mechanism, making it impossible to detect color rendering defects and adhesion stability issues of images and text under different lighting conditions in advance. This leads to a low pass rate for printed colored contact lens products, increases production costs, and makes it difficult to meet the market's high-quality demand for full-page image and text colored contact lenses. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a method and system for processing full-page images and text on colored contact lenses, thereby improving image and text processing efficiency and printing quality, and adapting to the mass production needs of colored contact lenses of different specifications.

[0066] Obtained colored contact lenses such as Figure 3 As shown.

[0067] Example 1

[0068] This embodiment is applied to the full-page image and text processing of daily disposable contact lenses. The specific steps are as follows: Obtain the base parameters of the contact lens to be printed and the target image and text material. The base parameters of the contact lens include a diameter of 14.2mm, a curvature of 8.6mm, and a light transmittance of 92%. The target image and text material is a floral pattern. The floral pattern is analyzed in layers using an image processing algorithm. A convolutional neural network is used to perform pixel-level layering of the target image and text material, separating the foreground feature layer, background feature layer, and transition feature layer of the floral pattern, and extracting the outline edge features, petal color features, and texture detail features of the flowers.

[0069] Based on the obtained curvature, diameter, and light transmission parameters of the contact lens substrate, an image-text matching model is constructed. Data on substrate parameters of different specifications of contact lenses with diameters of 13.8mm-14.5mm and curvatures of 8.4mm-8.8mm are collected to establish a training set. Through deep learning training, an image-text matching model that can automatically match the substrate parameters is obtained. The extracted floral pattern image features are input into the matching model for coordinate mapping and scaling to generate a full-page floral pattern image that perfectly matches the contact lens substrate.

[0070] Image rendering algorithms were used to perform color correction and lighting optimization on the initial version of the full-print floral pattern. Based on the light transmittance curve of the contact lens material, the color gradation parameters of each area of ​​the flower were adjusted to ensure that the flower colors are not distorted under oxygen-permeable conditions, thus ensuring that the floral pattern presents a natural and soft visual effect after the contact lenses are worn. Simulation testing algorithms were used to simulate the color rendering state and adhesion stability of the full-print floral pattern under daily natural light, indoor lighting, and strong light conditions. The clarity of the flower outline, color uniformity, and adhesion between the image and the substrate were tested under different environments.

[0071] Based on the test results, the graphic parameters are iteratively adjusted, with a focus on adjusting the parameters of flower outline edge smoothness, petal color saturation, and texture detail clarity. Once the simulation test results reach the preset standard, that is, the graphic color rendering is without deviation and the fit is without wrinkles under different lighting conditions, the final full-page graphic printing data for colored contact lenses is output. This printing data is stored in vector format and can be directly imported into the colored contact lens roller printing equipment to complete mass production.

[0072] Example 2

[0073] This embodiment is applied to the full-page image and text processing of monthly disposable contact lenses made of silicone hydrogel material. The specific steps are as follows: Obtain the base parameters of the contact lens to be printed and the target image and text material. The base parameters of the contact lens include a diameter of 14.5mm, a curvature of 8.7mm, and a material transmittance of 95%. The target image and text material is a geometric stripe image and text. The geometric stripe image and text is analyzed layer by layer using an image processing algorithm. A convolutional neural network is used to perform pixel-level layering of the target image and text material, separating the foreground feature layer, background feature layer, and transition feature layer of the geometric stripes. The outline features, stripe color contrast features, and line thickness details of the geometric stripes are extracted.

[0074] Based on the obtained curvature, diameter, and light transmission parameters of the contact lens substrate, an image-text matching model is constructed. Data on silicone hydrogel material and contact lens substrate parameters of different specifications are collected to establish a training set. Through deep learning training, an image-text matching model that can automatically match the substrate parameters is obtained. The extracted geometric stripe image features are input into the matching model for coordinate mapping and scaling to generate a full-page geometric stripe image initial version that perfectly matches the silicone hydrogel contact lens substrate.

[0075] Image rendering algorithms were used to perform color correction and lighting optimization on the initial version of the full-print geometric stripe pattern. Based on the transmittance curve of the silicone hydrogel material, the color gradation and contrast parameters of each area of ​​the stripe were adjusted to ensure that the geometric stripe is distortion-free and has clear edges under oxygen-permeable conditions, thus ensuring that the stripe presents a regular and uniform visual effect after the contact lens is worn. Simulation testing algorithms were used to simulate the color rendering state and adhesion stability of the full-print geometric stripe under daily natural light environment, indoor lighting environment, and strong light irradiation environment. The regularity of the stripe, color contrast, and adhesion stability between the image and the substrate were tested under different environments.

[0076] Based on the test results, the graphic parameters are iteratively adjusted, with a focus on adjusting the smoothness of the geometric stripe outline, color saturation, line thickness, and contrast parameters. Once the simulation test results reach the preset standard, i.e., the graphic color rendering is without deviation, the stripes are regular, and the fit is wrinkle-free under different lighting conditions, the final full-page graphic printing data for colored contact lenses is output. This printing data is stored in vector format and can be directly imported into the colored contact lens offset printing equipment to complete mass production.
