Description

Technical Field

[0001] The present invention relates to the technical field of myopia prevention and control, and specifically to a method for preparing a myopia prevention and control lens based on an individualized peripheral retinal defocus distribution design. Background Art

[0002] In recent years, with the change of lifestyle and the increase of electronic product use, myopia problem has become increasingly serious, especially among young people. Myopia not only affects the quality of life of individuals, but also may lead to a series of eye complications. Currently, the myopia correction lenses on the market mainly focus on the correction of central vision, while ignoring the attention to the defocus state of the peripheral retina. Studies have found that hyperopic defocus of the peripheral retina is one of the key factors leading to the elongation of the eye axis and the deepening of myopia.

[0003] However, traditional myopia correction methods cannot effectively solve this problem because they lack consideration of individual differences and cannot provide personalized peripheral defocus compensation. This not only limits the effect of myopia correction, but also fails to fundamentally prevent or delay the development of myopia. Therefore, the development of a myopia prevention and control lens that can be customized according to individual peripheral retinal defocus distribution data has become an urgent need in the current field of myopia prevention and control.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Combined with Figure 1 A method for preparing a myopia prevention and control lens based on an individualized peripheral retinal defocus distribution design comprises the following steps:

[0026] (a) using a specially designed peripheral retinal defocus measurement device to non-invasively measure the user's eyes to obtain peripheral retinal defocus distribution data of the user's eyes;

[0027] (b) transmitting the data obtained in step a to a remote data computing server via a network, wherein encryption measures are used in the data transmission process to protect user privacy and data security;

[0028] (c) The data calculation server generates personalized lens design parameters for the user's eye characteristics based on the received data using mathematical models and algorithms, wherein the mathematical models and algorithms include machine learning models and deep learning neural network models, which are used to improve the accuracy of defocus prediction and the rationality of lens design;

[0029] (d) according to the design parameters generated in step c, using a RV to automatically produce the final lens product;

[0030] Combined with Figure 1 The prepared lens product includes a central correction area and a peripheral compensation area, and a smooth transition zone is provided between the central correction area and the peripheral compensation area to ensure the visual comfort of the user when wearing it. The lens material includes polycarbonate, CR-39 resin and glass material to meet the needs and preferences of different users.

[0031] Combined with Figure 1 , and also includes step e, namely, performing quality inspection on the prepared lens product to ensure that its optical performance meets national standards, and the quality inspection includes transmittance testing, surface flatness inspection and curvature radius measurement.

[0032] The present invention is specifically implemented:

[0033] Step 1: Peripheral retinal defocus measurement

[0034] The user's eyes are comprehensively measured using a non-invasive peripheral retinal defocus measurement device specially designed for the present invention. The device can quickly and accurately obtain the peripheral retinal defocus distribution data of the user's eyes, ensuring the reliability and accuracy of the data. The measurement process is simple and quick, and the user only needs to sit in front of the device and follow the instructions.

[0035] Step 2: Data transfer and security protection

[0036] The data obtained in step 1 is transmitted in real time to a remote data computing server through a secure Internet connection. In order to protect user privacy and data security, all data are protected by encryption technology during transmission to prevent data leakage or illegal access.

[0037] Step 3: Data analysis and personalized design

[0038] After receiving the user's data, the data computing server uses preset mathematical models and advanced algorithms (such as machine learning models and deep learning neural network models) to conduct in-depth analysis of the data. These algorithms can generate personalized lens design parameters based on the user's retinal defocus distribution characteristics. The design parameters not only take into account the needs of central vision correction, but also specifically design precise compensation for the user's peripheral retinal defocus to ensure that the lens can provide a defocus effect opposite to the user's actual defocus.

[0039] Step 4: Lens product preparation

[0040] According to the design parameters generated in step 3, the final lens product is automatically produced using a lathe. The automated lathe can achieve micron-level processing accuracy, ensuring the high accuracy of the lens and meeting the requirements of personalized design. The lens product can not only effectively correct the user's central vision, but also produce an appropriate amount of positive defocus effect at the edge of its field of vision to improve the working environment of the peripheral retina and reduce the occurrence and development of myopia. The lens design specially sets a smooth transition zone between the central correction area and the peripheral compensation area to ensure the visual comfort of the user when wearing it.

[0041] Step 5: Quality Inspection

[0042] In order to ensure the quality of lens products and the safety of users, all finished lens products need to undergo strict quality inspection. Inspection items include but are not limited to transmittance test, surface flatness inspection and curvature radius measurement. Only lens products that pass all inspection items can be finally shipped and provided to users.

[0043] Step 6: Material Selection

[0044] The present invention supports the selection of multiple lens materials, including polycarbonate, CR-39 resin and glass materials. Different materials have their own advantages and can be selected according to the actual needs and preferences of users. For example, polycarbonate material is light and durable, suitable for daily wear; CR-39 resin material has good light transmittance and good visual effect; glass material has excellent optical properties and is suitable for users who have high requirements for lens quality.

[0045] In summary, the present invention provides a comprehensive method for preparing myopia prevention and control lenses from measurement, design to production, which ensures the personalization level of lens products and the myopia prevention and control effect through non-invasive measurement, data encryption transmission, personalized design, high-quality lens preparation and strict quality inspection. The present invention not only improves the accuracy and rationality of lens design, but also significantly enhances the wearing comfort and visual experience of users, providing an innovative and effective solution for myopia prevention and control.
