Abstract
Description
Technical Field
[0001] This invention relates to the field of multifocal lens technology, and in particular to a zoned scattering optical lens system and method for myopia control. Background Technology
[0002] Multifocal lens technology involves the design and manufacture of optical lenses for visual correction and accommodation. Its core lies in using multiple zones with different refractive powers within the lens structure to achieve visual compensation and correction at different viewing distances. This field mainly includes bifocal lenses, progressive multifocal lenses, functional regional lenses, and multi-zone lens systems that regulate the light propagation path through microstructure arrays. It is widely used for correcting refractive errors such as presbyopia, myopia, and hyperopia, as well as guiding and intervening in specific visual functions. It is an interdisciplinary field combining physical optics, visual neuroscience, and lens manufacturing processes. Traditionally, zoned scattering optical lens systems for myopia control refer to optical systems that use multiple functional zones with different optical properties designed on the lens substrate to regulate the scattering and focusing of light entering the eyeball, thereby intervening in axial development and controlling the increase in myopia. These systems typically employ a zoned structure with a central clear visual zone and a peripheral control zone. A microlens array generates a positive defocus effect in the peripheral region. The design generally includes determining the positions of the central and peripheral regions, setting the range of regional refractive power changes, establishing a defocus intensity model, and using simulation to guide the microstructure arrangement.
[0003] In existing designs of zonal scattering optical lenses, the lens structure is often established based on fixed area divisions and empirical parameters. This lack of a means to identify individual visual perception characteristics in the spatial frequency dimension results in inconsistency between the frequency functional area coverage and the wearer's perception state. The positioning accuracy of frequency response in each area of the lens is insufficient, making it difficult to achieve dynamic control based on the perceptual differences between the two eyes. Frequency stimulus distribution may be repetitive or incomplete, and the frequency response and structural space are not accurately mapped. This can easily cause blurring of the defocus direction and shift of the area of action in the interference effect. The lens imaging performance does not match the intervention requirements, affecting the stability and sustainability of the control strategy. Summary of the Invention

[0023] This invention provides a zoned scattering optical lens system for myopia control, such as... Figure 1-2 The diagram shown illustrates a partitioned scattering optical lens system for myopia control, which includes: The frequency perception recording module collects the refractive state, pupil diameter and axial length of the left and right eyes of the wearer of the scattering optical lens for myopia control. It extracts the corresponding visual response records in segments according to the spatial frequency type, compares the differences in the frequency response positions of the two eyes in sequence, filters the numbered content with consistent positioning in the response records of both sides, verifies the stable area of frequency response in the perception record, and generates a list of frequency response numbers. The frequency priority sorting module reads the distribution position of the frequency number within the frequency interval according to the position of the number in the frequency response number list and the arrangement order of the sensing records, counts the cumulative coverage times of the number in the distribution map according to the frequency segment interval range, identifies the sequential position of the number in the entire distribution map, constructs a frequency arrangement order index and establishes a mapping sequence, and generates a frequency coverage order identification table. The lens ring configuration module calls the frequency index content in the frequency coverage sequence identifier table, divides the lens structure into the central optical area and multiple ring areas, extracts the projection diameter and rotation angle direction of the boundary of each ring area, matches them with the spatial sequence of the ring area according to the index number, records the mapping relationship of the frequency identifier on the lens spatial coordinates, organizes all regional spatial frequency combinations, and generates a frequency distribution area map. The imaging target setting module reads the light diffusion difference description of the lens material in the radial ring based on the frequency content in the frequency distribution area map, matches the imaging performance type of each frequency item, filters the frequency group that can form interference bands, records the corresponding lens coordinates and frequency zone number, and generates an imaging target chart. The microstructure layout output module retrieves the microlens structure pattern identifier for each zone based on the zone number and frequency content in the imaging target chart. It extracts the descriptions of the arrangement density, diameter variation and refractive interface differences in the structure, numbers the structure patterns according to the frequency labeling order and fills them into the zone positions. It then integrates them according to the lens area order to form a structure configuration graphic and generate the optical lens structure layout result.
[0024] The frequency response number list includes refractive state data number, pupil diameter corresponding number, axial length number, visual frequency response location number, binocular frequency response difference number, and response stability region number. The frequency coverage sequence identification table includes frequency number distribution location, cumulative coverage times of frequency segments, frequency number sequence index, and frequency number mapping sequence. The frequency distribution area map includes central optical zone frequency identifier, annular zone frequency identifier, annular zone projection diameter parameter, annular zone rotation angle parameter, frequency-spatial sequence correspondence, and frequency spatial mapping coordinates. The imaging target chart includes frequency item imaging type, interference band frequency combination, frequency zone number, and corresponding lens coordinate position. The optical lens structure layout results include zone structure style number, microlens arrangement density, microlens diameter variation, refractive interface difference parameter, and frequency labeling order.
[0025] Specifically, such as Figure 2 , 3 As shown, the frequency sensing recording module includes: The physiological parameter acquisition submodule acquires the refractive state, pupil diameter and axial length of the left and right eyes of the user wearing the regional scattering optical lens. The data are collected by a refractive analyzer, a pupil tracker and an axial length measurement, respectively. The data are then recorded after being uniformly numbered to generate a basic physiological parameter dataset. The physiological parameter acquisition submodule acquires the refractive state, pupil diameter, and axial length of the left and right eyes of the user wearing regional scattering optical lenses. This process begins with the refractive state acquisition using a refractive analyzer. When starting the device, the subject's head is fixed, ensuring their eyes are parallel and centered with the instrument's light output port. The test distance is adjusted to 5 meters, and the autofocus function is used to position the tested eye at the far point. The image data reflected back along the principal optical axis in each direction is recorded. The spherical and cylindrical powers are calculated based on the image sharpness. If the measured spherical power for the left eye is -1.25D and the cylindrical power is -0.50D, and for the right eye it is -1.50D and the cylindrical power is -0.25D, then two data items are recorded and associated with the numbers 001 and 002 respectively. Subsequently, the pupil tracker is activated, and the ambient brightness is adjusted to a low-light state to reduce the influence of the iris on pupil size. An infrared camera is used to track both eyes. Sampling was performed to capture consecutive frames of images. In each frame, the pupil boundary was identified using a pixel-contrast edge detection method, and the maximum transverse diameter was calculated by ellipse fitting. The average of the fitted diameters from five frames was taken to obtain pupil diameter values of 4.1 mm for the left eye and 4.3 mm for the right eye. Next, using an axial length measurement system, the subject was asked to fixate on a reference point in the center of the screen. The system emitted a low-intensity laser, and by receiving the time difference of the signal returned after reflection from the retina, combined with the speed of light to convert the path length, the longitudinal length from the anterior cornea to the retina was calculated. The axial length of the left eye was measured to be 23.85 mm, and that of the right eye was 24.10 mm. All measured parameters were sequentially numbered by eye and entered into the data system to generate complete data entries numbered 001 and 002. Finally, a dataset of basic physiological parameters including refractive state, pupil diameter, and axial length was obtained.
[0026] The frequency response comparison submodule is based on the basic physiological parameter dataset. It calls the spatial frequency label value corresponding to the visual stimulus, divides the left and right eyes into frequency segments, and compares the numbers. It filters out the numbers whose response difference is lower than the consistency threshold and generates a list of consistent frequency response localization numbers for both eyes. After calling the spatial frequency marker value corresponding to the visual stimulus, the user's visual stimulus response is compared between the left and right eyes. First, basic parameter records containing refractive error, pupil diameter, and axial length are read. Based on these parameters, a spatial frequency stimulus image with high matching degree is selected. For example, for numbered samples with a refractive error difference within 0.5D and a pupil diameter difference within 0.5mm, a fringe pattern with a spatial frequency of 6cpd is selected and presented in the visual field of the left and right eyes respectively using a visual stimulus device. After each stimulus test, the numbered response intensity value is recorded. During this process, a set of numbers is generated for each test; for example, the response to number 001 (left eye) is recorded as R_001, and the response to number 002 (right eye) is recorded as R_002, corresponding to the same spatial frequency. By reading the response intensity value output by the image recognition system, the... The response difference between the left and right eyes is calculated by performing an absolute value operation on the response amplitude. For example, if the response intensity of the left eye is 0.85 and that of the right eye is 0.72, the difference is 0.13. This difference is then compared with a preset consistency threshold. If the difference is less than the threshold, the eyes are considered to be in agreement. The threshold can be set to 0.15 based on the average response difference among different groups of people. This threshold is derived from setting an upward limit on the statistical average of the response differences of people with normal visual function under the same frequency stimulus. After multiple rounds of testing and numbering for all frequency points, number combinations with response differences lower than 0.15 are selected, such as A001 and B001, A003 and B003, etc. The corresponding frequency values such as 6cpd and 12cpd are also recorded. Finally, a binocular frequency response positioning consistency number list containing multiple number pairs and frequency correspondences is formed.
[0027] The stable region identification submodule extracts the corresponding frequency parameters from the binocular frequency response localization consistency number list, calculates the response variance value of the number, filters the data numbers below the set response threshold, and establishes a frequency response number list. After extracting the corresponding frequency parameters from the binocular frequency response localization consistency number list, the response amplitude fluctuation of the corresponding number at each frequency is further analyzed. First, the number pairs selected in the previous module are classified into different frequency ranges. For example, number pairs A001 / B001 and A003 / B003 belong to the 6cpd and 12cpd frequency ranges. The left or right eye response intensity values of all number pairs at the same frequency are listed. At the 6cpd frequency, if the response values corresponding to the numbers are 0.82, 0.85, 0.81, 0.87, and 0.84 respectively, the response differences of these five sets of data are calculated. Each set of response values is compared with the response values at the same frequency. The difference between the average response values is calculated, and the variance of the response values is taken after error calculation for all response values. This variance is used to determine the stability between the response values. The preset response value variance threshold is set based on the average fluctuation of 10 groups of normal visual function individuals at the same frequency in the previous calibration test. For example, if the response value variance is 0.00046, the threshold is set to 0.0005. When the response variance of the numbered combination at the actual frequency is lower than this threshold, it is identified as a stable region number. The numbers of this frequency range are collected into the frequency response number list. The final list will contain all numbers that meet the requirement that the response fluctuation is within a reasonable range, forming a number list for the frequency response stable region.
[0028] Specifically, such as Figure 2 , 4 As shown, the frequency priority sorting module includes: The number reading submodule obtains the arrangement order of frequency numbers in the frequency response number list in the sensing record, classifies the frequency interval corresponding to each frequency number in combination with the sensing record data, extracts the position label of the number within the frequency segment, and establishes a number position index set within the frequency segment. First, the frequency response number list is analyzed item by item, extracting each frequency number and its corresponding frequency value. The order is then confirmed based on the frequency number's position in the perception record. By retrieving the visual stimulus presentation order recorded in the perception record file, the index of the first trigger of each frequency number is located. For example, if number F101 appears at the 5th stimulus and number F102 appears at the 9th stimulus, then the position order of F101 is 5 and F102 is 9. The index of this number's arrangement in the perception record sequence is recorded. Then, based on the frequency value corresponding to each frequency number, frequency ranges are divided. The complete frequency range is divided into low-frequency, mid-frequency, and high-frequency segments according to fixed intervals. For example, a frequency range of 0–5 cpd is set as low frequency. Frequency bands are categorized as follows: 5–10 cpd is the mid-frequency band, and 10–15 cpd is the high-frequency band. For example, if the frequency value of number F101 is 6.5 cpd, it is classified as a mid-frequency band; if the frequency value of number F102 is 3.2 cpd, it is classified as a low-frequency band. After classifying the frequency bands by frequency number, the position tag within that frequency band is extracted to confirm its numbering order within the same frequency band. For instance, if the mid-frequency band contains F101, F105, and F108, and F101 is ranked 2nd in the sensing record, then its position tag within the mid-frequency band is 2. All frequency numbers are processed in this way, and their corresponding ranking tags within the frequency band are matched one by one. Finally, the frequency band, frequency number, and position tag within the band are summarized to establish a frequency band position index set.
[0029] The frequency distribution statistics submodule is based on the number position index set within the frequency band, counts the cumulative coverage times of the number within the frequency band in the distribution map, calculates the sequence position value of each frequency number in the overall distribution map, and obtains a list of cumulative coverage positions of the frequency band. First, all entries in the index set of number positions within the frequency band are read sequentially. The frequency of each number in the perception record is extracted. The position and frequency of occurrence are confirmed by checking whether each number is activated or marked in the perception record. For example, if number F101 is called 4 times in the stimulation process, number F102 is called 2 times, and number F103 is called 5 times, then their cumulative coverage counts are recorded as 4, 2, and 5 respectively. Next, the cumulative coverage counts of all numbers under each frequency band are added together and sorted according to frequency band. At the same time, the sequential position of each number in its corresponding frequency band is confirmed. If the numbers in the mid-frequency band are sorted as F101, F103, F1... 06 corresponds to coverage times of 4, 5, and 3. Therefore, the sequence position value of F101 is the first, F103 is the second, and F106 is the third. The current number position is accumulated by incrementing the cumulative value of the previous number. During the statistical process, the frequency band attribute, cumulative occurrence times, and sequence position of each number are recorded one by one to form the sorting structure of the numbers within the frequency band. At the same time, the global position of each number in the entire sensing sequence is confirmed, and its global occurrence order and number correspondence are recorded. Finally, the cumulative coverage position list of the frequency band is output, where each record reflects the total number of times a number appears in its frequency band and its position number in the overall sensing record.
[0030] The sequential index construction submodule extracts the number arrangement order from the cumulative coverage position list of frequency bands, performs sequential index encoding on each number position, and integrates them to form a frequency coverage sequence identifier table; First, the numbering information in the cumulative coverage position list of frequency bands is sorted in ascending order according to global position. The actual sorting order of all numbers in the sensing record is determined sequentially, and each number is assigned a consecutive sequential number in its position in the sorting. The sequential number is recorded using a standardized encoding form. For example, the first number F102 in the sensing record sequence is assigned the value S_001, the second F101 is S_002, the third F106 is S_003, and so on. After completing the sequential index encoding operation of all numbers, the frequency number, the corresponding frequency value, the cumulative coverage count, and the sequential index are integrated into a complete set of identification information. For example, the frequency value of number F101 is 6.5cpd, it appears 4 times, and the corresponding sequential index is S_002. The record generated is {F101, 6.5, 4, S_002}. This operation is repeated to encode and integrate all numbers to complete the sequential labeling of all numbers. Finally, a frequency coverage sequence identification table is formed. This table records the actual arrangement order of all frequency numbers in the sensing sequence and their corresponding encoded index information.
[0031] Specifically, such as Figure 2 , 5 As shown, the lens ring configuration module includes: The structural division submodule obtains the frequency coverage sequence identifier table, sets the diameter of the optical center area and the boundary projection diameter and rotation angle of each annular area according to the lens center area and annular zone division logic, establishes the spatial region sequence according to the annular zone sequence number, and generates the lens annular zone spatial index table. First, read all frequency numbers and their sequential numbers from the identification table, and rearrange them according to the sequential numbers for confirmation. Then, based on the lens's geometric design rules, set the division parameters for the lens's optical center area and multiple annular functional areas, determining the diameter of the optical center area, for example, setting the diameter to 4.0mm as the starting point for the central non-annular area. Then, extend several annular areas outwards from this center point at equal intervals. The boundary projection diameter of each annular area is set to a continuously increasing fixed value, for example, 6.0mm for the first annular area, 8.0mm for the second, and 10.0mm for the third, ensuring that the width of each annular area is 2.0mm. Further divide the annular areas according to angular direction, with each annular area equally divided into several fan-shaped segments along the circumference. If 360° is divided into 8 directions, each direction being 45°, forming numbered labels A1 to A8, and each ring number is combined with its corresponding sector number to form a unique spatial region number, such as "R1-A1" and "R2-A5", etc., and sorted clockwise from the center outwards and from the starting angle, all spatial region numbers are arranged sequentially to form a linear spatial region sequence. During the process, corresponding hierarchical attributes and angle segment information are set for each number. For example, "R3-A2" belongs to the 2nd sector of the 3rd ring. Subsequently, all established spatial region numbers and their hierarchical, directional, and sequence information are summarized to form structural data, and finally, a lens ring spatial index table is established. This table clearly indicates all available spatial region numbers and their organizational order from the center to the outer ring of the lens.
[0032] The frequency mapping submodule calls the frequency index number in the frequency coverage sequence identifier table, and according to the position order of each region in the lens ring spatial index table, maps the corresponding frequency index to the ring zone sequence, records the spatial position of the frequency number in the lens coordinate system, and establishes a frequency spatial coordinate mapping matrix. After obtaining the sequence of all frequency numbers, the positions are sequentially numbered starting from S_001, matching them one by one with the spatial region sequence arranged clockwise from the center outwards in the lens ring spatial index table. The first-order frequency number is mapped to the R0 central region, the second to R1-A1, the third to R1-A2, and so on, until all frequency numbers are assigned. During the mapping process, the numbering is recorded strictly according to the sequential correspondence. For example, frequency number F101 corresponds to S_002 and is mapped to lens region R1-A1, recorded as {F101, S_002, R1-A1}. A1}, along with the ring zone level of the region being 1, the angular direction being A1, and the spatial sequence number being 2. Each time a mapping is completed, a new row is added to the matrix until all frequency numbers in the frequency coverage sequence identifier table are mapped one-to-one with the lens spatial region. Based on this, the core content of each mapping relationship is organized, including key information such as frequency number, sequence index, target spatial number, ring zone level, angular partition, and spatial sequence position. This forms the spatial mapping structure of the frequency number in the lens coordinate system, and finally outputs the frequency spatial coordinate mapping matrix, where each row represents the precise location of a frequency number in the lens space.
[0033] The spatial combination and organization submodule classifies the frequency index values in all regions according to their spatial location based on the coordinate records of the frequency numbers in the frequency spatial coordinate mapping matrix, extracts the regional frequency groups and arranges them in order, and establishes a frequency distribution regional map. First, all records in the mapping matrix are grouped according to spatial region numbers. Frequency numbers with the same spatial number are aggregated into one frequency group. For example, if the R1-A1 region maps to three frequency groups: F101, F108, and F110, then the frequency group {F101, F108, F110} is created within this region. The same operation is performed on all spatial regions. After completing the frequency grouping and classification for the entire lens region, the numbers within each frequency group are re-sorted according to the region order set by the lens structure. For example, within a region, the frequency group number F101 is sequentially encoded as S_002, F108 as... If S_005 and F110 are S_003, then after reordering they become F101, F110, and F108. The numbers within each region's frequency group are sorted from smallest to largest according to their sequential codes. After sorting, each region and its corresponding frequency group are arranged sequentially from the center outwards, from left to right, and then clockwise, merging into the basic structure of the lens frequency distribution map. During the process, the level, orientation, sequence number, and corresponding frequency group content of each spatial region are marked. Finally, a frequency distribution area map is created, which covers all structural areas of the lens and accurately presents the set of frequency numbers and their arrangement order allocated to each spatial location.
[0034] Specifically, such as Figure 2, 6 As shown, the imaging target setting module includes: The optical performance matching submodule reads the light diffusion difference description data of the lens material at the corresponding ring position based on the frequency number sequence in the frequency distribution area map, matches the diffusion characteristics of the material region corresponding to the spatial coordinates of the frequency number, and generates a frequency diffusion matching result set. First, the frequency distribution map is read item by item. The frequency number corresponding to each spatial region in the map is extracted sequentially, and the coordinate index of each number is confirmed by combining the spatial coordinate label marked in the map. The confirmation method is to read the ring layer and sector number of the number to form a clear spatial positioning point. For example, when the frequency number F210 is located in the A3 region of the second ring, it is positioned as "R2-A3". Then, the material diffusion characteristic data is retrieved. In this process, the material diffusion parameters of each ring region are retrieved according to the pre-recorded material diffusion parameters in the lens material library. The diffusion description value of the corresponding material is selected from the library according to the position of each number. For example, the diffusion description of the central region is 0.12, the diffusion description of the first ring region is 0.17, the diffusion description of the second ring region is 0.24, and the diffusion description of the third ring region is 0.31. All diffusion amounts are recorded as relative light diffusion increment values based on the light diffusion value of the central region material. That is, the diffusion value of the central region is used as the reference value, and the diffusion increment of the material in other regions is the difference from this reference value. The difference is indicated to facilitate subsequent matching operations. After obtaining the diffusion amount, a range judgment action is performed, classifying the diffusion value into four ranges: 0.00–0.20, 0.21–0.40, 0.41–0.60, and 0.61–1.00. If the diffusion value falls into a certain range, a diffusion level label is assigned to that number. During the judgment process, a comparison operation is performed one by one. For example, if the diffusion value of the second ring where number F210 is located is 0.24, then its value falls into the 0.21–0.40 range and is recorded as "mid-range diffusion level". If the number F011 is located in the central area with a diffusion value of 0.12, it falls into the 0.00–0.20 range and is recorded as "low diffusion level". Then, the number, coordinate position, ring number, diffusion value and diffusion level are combined into a matching record. The above process is repeated to perform the same reading, matching, judgment and recording actions on all frequency numbers in the entire drawing. All matching results are integrated into a complete diffusion matching structure according to the reading order. After all numbers are processed, the frequency diffusion matching result set is finally formed.
[0035] The interference frequency filtering submodule determines whether the frequency item exceeds the interference judgment threshold based on the correspondence between the frequency number and the material diffusion characteristics in the frequency diffusion matching result set, extracts the frequency number that meets the interference characteristic judgment condition, and records the corresponding lens coordinates and ring number position to generate an interference frequency position information set. First, each numbered record in the matching result set is read sequentially, and the diffusion value and diffusion level are retrieved from the record. Then, an interference judgment threshold comparison is performed. This threshold is used to distinguish whether it is a material region with interference level. The interference threshold is set to 0.30 based on the diffusion amount statistics. This threshold is based on the trend analysis of the diffusion data of 30 sets of lens materials in the previous experiment. By constructing a diffusion value-scattering intensity relationship curve, the slope change point fitting algorithm was used to identify the inflection point where the diffusion value shows a significant increase in light scattering intensity at about 0.30. Therefore, 0.30 was determined. To determine the interference threshold, 0.30 is used as a reasonable reference. During the judgment process, the diffusion value of the number is directly compared with 0.30. For example, if the diffusion value of number F312 is 0.26, then a comparison of 0.26 and 0.30 is performed, indicating that the interference condition is not met. If the diffusion value of number F408 is 0.34, then a comparison of 0.34 and 0.30 is performed, indicating that the interference condition is met. When a number meets the condition, its coordinate region and ring number are immediately read and its position information is recorded. This record is written to the interference frequency position temporary storage area. For example, F408 corresponds to spatial position R3-A5, and it is recorded as... {F408, R3-A5, Third Ring}, repeat the same judgment action for all numbers, without skipping any record entries. Ensure the integrity of interference screening by reading and judging each entry one by one. Then, perform a sorting action on all number information that meets the interference characteristics, arranging them in coordinate order from the inside to the outside. For example, the number located in the second ring is placed before the third ring. Then, perform a secondary sorting by angle number from A1 to A8, so that the interference position information has continuity in the overall lens structure. Finally, combine all the selected interference frequency numbers, corresponding coordinates and ring numbers to form the interference frequency position information set.
[0036] The target chart generation submodule calls the frequency number, coordinate position and ring number of the interference frequency location information set, summarizes and annotates the spatial information, establishes the target correspondence between frequency and lens coordinates according to the frequency group arrangement order, and generates the imaging target chart. First, the interference frequency location information set is read, treating each interference number as a main data unit of the chart. Then, the placement point in the chart is determined based on the coordinates of the number record. For example, if number F408 is located in area A5 of the third ring band, then the grid point corresponding to the fifth sector of the third ring band in the target chart is labeled as F408. Next, the labeling order is determined based on the order of the numbers in the interference frequency set. Numbers appearing earlier in the sequence are marked with their earlier sequence number in the chart. For example, if F301 is located in area A2 of the second ring band and is the second record in the interference set, then it is labeled as the second sequence point in this area. This process is repeated to label all the interference frequency numbers one by one. The lens rings are arranged in layers from the center to the outermost ring, with the central area marked at the innermost layer. Then, the layers are marked outward in the order of R1, R2, R3. Within each layer, the marking order is further executed from A1 to A8 according to angle, ensuring that the coordinate arrangement in the chart is consistent with the actual structure of the lens. During the marking process, the number, ring layer, and sector position are integrated and written into the chart unit. For example, the marking in R2-A3 is written as {F305, second ring, sector A3}. After all areas are marked, the chart merging action is performed to summarize the coordinate marking information of all layers into a unified structure, ultimately forming a complete target correspondence between frequency and lens coordinates, thereby generating the imaging target chart.
[0037] Specifically, such as Figure 2 , 7 As shown, the microstructure layout output module includes: The structure pattern retrieval submodule retrieves the microlens structure pattern identifiers configured in the bands based on the band number and frequency item sequence in the imaging target chart, establishes the correspondence between frequency number and structure pattern, and generates a frequency structure pattern mapping set. First, the imaging target chart is read item by item, retrieving each frequency number and its corresponding band code position simultaneously. This is used as a search entry point to access the structure pattern database for searching the structure pattern number. During the search, the band code is used as the key search value. For example, if a frequency number F120 is recorded in band R2-A4 of the chart, then R2-A4 is used as the search condition to extract the microlens structure pattern identifier configured for that band from the database. Assuming the structure pattern number corresponding to R2-A4 is ST_09, then a record is established linking the frequency number F120 with the structure pattern number ST_09. Then, the next frequency number F121 is read, and its corresponding band code R1-A2 is read. This is used as the next search key to retrieve the structure pattern, for example, band R1-A2. If the configuration structure pattern number ST_03 is configured, the record will be {F121, ST_03}. During the retrieval process, if multiple frequency numbers are found in the same band, each number will be recorded independently without merging. For example, if F135 and F136 are both in R3-A1, they will be written as {F135, ST_11} and {F136, ST_11} respectively. To ensure the consistency of the retrieval, all structure pattern numbers are defined as single-value types by the database, and there is no fuzzy matching or multiple selection. The retrieval action depends entirely on the correspondence between the band code and the fixed fields in the database. After each successful match, a corresponding item is added to the mapping record, and the result set is arranged in the order of reading. After all frequency numbers have been bound to the structure pattern, all mapping records are integrated in sequence to finally generate the frequency structure pattern mapping set.
[0038] The structural parameter extraction submodule extracts the arrangement density value, diameter variation range and refractive interface parameter description of the corresponding microlens structure according to the structural pattern number of each group in the frequency structural pattern mapping set, and fills them into the structural parameter set in frequency order to obtain the zone structural parameter sequence table. First, the frequency number and structure pattern number recorded in the mapping set are read one by one. Then, the structure pattern number is used as a parameter to search the structure parameter library. From the library, the arrangement density parameter, diameter variation range parameter, and refractive interface description parameter corresponding to the number are read sequentially. For example, when reading structure pattern number ST_03, its arrangement density of 200 pcs / mm², its diameter variation range of 0.08–0.12 mm, and its refractive interface description of spherical interface range of 12–25° are retrieved from the parameter library. These three types of data are combined to form a complete structure parameter entry, and it is sequentially bound to the corresponding frequency number. For example, F121 corresponds to ST_03, so its structure parameter entry is {200, 0.08–0.12, spherical 12–25°}. Then, the next structure pattern ST_09 is read, and the parameters are retrieved from the library. The corresponding arrangement density of 155 pcs / mm², diameter variation range of 0.10–0.22 mm, and refractive interface description of multi-curvature interface angle of 16–28° are read from the library and written into the parameter entry of the corresponding frequency number F120. The original order of the frequency numbers must be strictly maintained. The extracted parameters are filled into the structural parameter set in the same order. If multiple records of the same structural pattern number appear, the parameter reading action is repeated. An independent entry is generated for each frequency number. For example, F135 and F136 both correspond to ST_11, so their corresponding parameter groups {arrangement density value, diameter variation range, interface description} are filled in independently. After the parameter extraction and filling values are completed for all mapping records, the parameter entries arranged in order are structured and stored in the sequence list, and finally the strip structure parameter sequence table is obtained.
[0039] The structural graphics integration submodule calls the structural parameter content in the zone structural parameter sequence table, integrates the structural style and parameter combination into the zone position according to the spatial region of the lens, constructs the structural graphics and outputs the overall structural arrangement information of the lens, and establishes the optical lens structural layout result; First, using the spatial region sequence of the lens as the main axis, the frequency number corresponding to each spatial region is read sequentially by scanning from the central region outwards. Then, the corresponding structural pattern and three types of structural parameter values are retrieved from the structural parameter sequence table using the frequency number. The retrieved structural pattern number is used as the basic graphic construction template for that spatial region. At the same time, the arrangement density, diameter range, and refractive interface description are sequentially marked in the parameter description area of the template. For example, the spatial zone R2-A4 corresponds to the frequency number F120, and its structural pattern number ST_09 and its parameter group {155pcs / mm², 0.10–0.22mm, multiple curvature 16–28°} are integrated into R. The graphic construction unit 2-A4 is then used to enter the next spatial region for the same structural loading process. For example, region R1-A2 corresponds to F121, and its structural style ST_03 and parameters {200pcs / mm², 0.08–0.12mm, spherical 12–25°} need to be loaded into the graphic region R1-A2. The entire integration process is executed in the order of lens spatial region numbering to ensure that all regions are arranged in the natural structural order of the lens ring. After all region parameters and styles are integrated, the graphic units of each region are connected in sequence to form a complete structural layout graphic, and a set of overall lens structural arrangement information is formed, finally establishing the optical lens structural layout result.
