Description

Technical Field

[0001] This disclosure relates to the field of optical equipment technology, and in particular to a control method, apparatus, control system, and electronic equipment for an eye optical device. Background Technology

[0002] Myopia has become a global public health problem, with an increasing incidence and a trend towards younger ages. Epidemiological studies have confirmed that outdoor activities can reduce the risk of myopia, with the key mechanism being the stimulation of retinal dopamine release by high-intensity natural outdoor light. Current ocular optical devices employ a fixed-dose PBM (phototherapy by light) regimen, treating outdoor activities and PBM treatment independently. Furthermore, existing outdoor detection relies on a single light sensor, resulting in a high error rate. The fixed-dose regimen also ignores the fluctuations in an individual's daily outdoor exposure, leading to overtreatment on days with sufficient outdoor exposure and insufficient treatment on days with insufficient outdoor exposure. Improvements in control methods are urgently needed. Summary of the Invention

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0014] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0015] The technical solutions of this disclosure and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0016] First, combine Figure 1 The control method for the eye optical device provided in the embodiments of this disclosure will be described by way of example.

[0017] Figure 1 This is a flowchart illustrating a control method for an eye optical device according to an exemplary embodiment.

[0018] It should be noted that the control method for the ophthalmic optical device provided in this embodiment can be executed by a control device for the ophthalmic optical device, which can be implemented by software and / or hardware. The control device can be an electronic device or can be configured within an electronic device to enable the electronic device to have myopia prevention and control functions.

[0019] In this embodiment, the electronic device may include, but is not limited to, terminal devices, servers, etc., and this embodiment does not specifically limit the electronic device.

[0020] like Figure 1 As shown, the control method for this eye optical device includes the following steps: Step 101: Obtain activity monitoring data for the target object.

[0021] It should be noted that the activity monitoring data includes monitoring data of the target object in at least one of the following dimensions within a preset time range: illuminance data, location data, and motion status data.

[0022] As an example, activity monitoring data includes daily monitoring data for the target object in at least one of the following dimensions: illuminance data acquired via a light sensor, such as ranging from 0 to 120,000 lux with an accuracy of ±3%; location data acquired via a dual-frequency GPS / GNSS receiver module with a positioning accuracy of ±3m, matched with points of interest (POIs) on a map; and motion state data acquired via a 6-axis inertial measurement unit (IMU), capable of detecting motion states such as walking, running, cycling, and sitting. For example, illuminance data, location data, and motion state data of the target object's environment are continuously collected over a 24-hour period.

[0023] Step 102: Determine the effective outdoor time for the target object based on the activity monitoring data.

[0024] In some embodiments, a preset time range is first divided into multiple sub-time periods. For each sub-time period, the activity scene of the target object is determined based on the activity monitoring sub-data within that sub-time period. The activity scene includes outdoor scenes and indoor scenes. The specific determination rules are as follows: if the illuminance data is greater than or equal to a first illuminance threshold (e.g., 1000 lux) and the location data corresponds to an outdoor location (not inside a building and not an indoor POI via GPS positioning), the activity scene is determined to be an outdoor scene; if the illuminance data is less than or equal to a second illuminance threshold (e.g., 500 lux), or if the location data corresponds to an indoor location (e.g., GPS is located inside a building), the activity scene is determined to be an indoor scene. If the illuminance data is greater than the second illuminance threshold but less than the first illuminance threshold (i.e., in the gray zone of 500-1000 lux), it is determined whether the movement state is a non-seated state; if the movement state is a non-seated state and the location data corresponds to an outdoor location, the activity scene is determined to be an outdoor scene; if the movement state is a seated state, the activity scene is determined to be an indoor scene.

[0025] After determining the activity scenario, the effective duration of each sub-time period is determined based on the scenario and the illuminance data within that sub-time period. If the activity scenario is outdoor, an initial score is determined based on the illuminance data within each sub-time period. For example, a maximum activity quality score of 100 points / hour is given when the illuminance is greater than 10,000 lux, 80 points / hour is given when the illuminance is between 5,000 and 10,000 lux, and 60 points / hour is given when the illuminance is between 1,000 and 5,000 lux. Based on the activity status within the sub-time period, a score weight is determined, with users in an active state receiving a minimum 20% activity quality bonus. Specifically, if the active state is not sedentary, the score weight is 1.2; if the active state is sedentary, the score weight is 1.0. Based on the initial score and score weight, a target score for each sub-time period is determined, and this target score is then converted into effective duration according to certain rules. If the activity scenario is indoors, the target score for each sub-time period is determined to be a specified score (e.g., 0 points, or a lower score set based on the indoor activity situation), and this score is also converted into effective duration. Finally, based on the effective duration within each sub-time period, the effective outdoor duration of the target object is determined, which is to add up the effective duration of all sub-time periods for outdoor scenes.

[0026] Step 103: Determine the target duration and target power density of the eye optical device based on the effective outdoor time.

[0027] In some embodiments, to accurately determine the target duration and target power density of an eye optical device, one implementation method for determining the target duration and target power density of the eye optical device may involve determining a correspondence between at least one duration range and at least one combination; the duration value within the duration range is negatively correlated with the duration and power density in the corresponding combination; obtaining a first duration range to which the effective outdoor duration belongs; determining the duration in the combination corresponding to the first duration range as the target duration; and determining the power density in the combination corresponding to the first duration range as the target power density. This allows for quick and accurate matching of the most suitable target duration and target power density combination based on the user's actual effective outdoor duration. Whether for short-term outdoor leisure or long-term outdoor work, appropriate parameters can be found to fully meet diverse usage scenarios.

[0028] In some embodiments, after determining the target duration and target power density of the ophthalmic optical device based on the effective outdoor duration, the target duration is adjusted according to the current weather conditions; and / or, the effective outdoor power density is determined based on the effective outdoor duration; it is determined whether the sum of the effective outdoor power density and the target power density is greater than a safe power density value; if the sum is greater than the safe power density value, the target power density is adjusted so that the re-determined sum is less than or equal to the safe power density value. Thus, by introducing an environmental perception and dynamic adjustment mechanism, the safety and adaptability of the ophthalmic optical device are significantly improved.

[0029] As an example, a daily outdoor activity target can be set at 2400 activity points, equivalent to 120 minutes of effective outdoor activity time. The accumulated activity points for the day are calculated based on the effective outdoor time. These points are then compared to the target value (2400 points) to calculate the activity deficit. The supplementary target duration is calculated based on a ratio of 1 minute of PBM supplementary therapy for every 400 activity deficit points, with a maximum of 6 minutes / day. The target power density is in the range of 8 to 50 mW / cm², with an initial default of 20 mW / cm², which can be adjusted according to the activity deficit using a specific rule, such as "Target Power Density = CLAMP(20 + (deficit / 2400) × 10, 8, 50)", where deficit is the activity deficit. A supplementary therapy reminder is triggered or therapy is automatically started after the user returns indoors; and daily activity levels and treatment data are recorded for long-term trend analysis and algorithm optimization.

[0030] After determining the target duration and target power density of the ophthalmic optical equipment based on the effective outdoor time, the target duration is adjusted according to the current weather conditions. For example, if a rainy weather forecast is detected, the recommended supplementary treatment duration is automatically increased by 30%, but not exceeding the upper limit of 6 minutes. Simultaneously, the effective outdoor power density is determined based on the effective outdoor time (which can be calculated from illuminance data, etc.), and it is checked whether the sum of the effective outdoor power density and the target power density is greater than a safe power density value (e.g., 50 mW / cm²). If the sum is greater than the safe power density value, the target power density is adjusted so that the re-determined sum is less than or equal to the safe power density value.

[0031] Step 104: Based on the target duration and target power density, control the eye optical device to perform light projection processing on the target object's eye.

[0032] In some embodiments, when a trigger controller on an ophthalmic optical device detects that a user has returned indoors from outdoors and that outdoor activity is insufficient (i.e., an activity gap exists), it automatically triggers a treatment reminder or directly controls the photobiomodulation therapy module (PBM) of the ophthalmic optical device to initiate treatment. The PBM treatment module emits light at a predetermined target power density using red LEDs (660±5nm, 4 per side, such as the inner edge of the upper edge of the frame) and near-infrared LEDs (830±10nm, 4 per side, alternating with red light), for a target treatment duration, to project light onto the target subject's eyes to compensate for the photobiomodulation dose lost due to insufficient outdoor activity.

[0033] In some embodiments, the total daily PBM treatment dose (maximum cumulative energy density) can be set to less than or equal to 15 J / cm², calculated as "total dose = Σ(power density × treatment time) ≤ 15 J / cm²".

[0034] The control method for an ophthalmic optical device provided in this disclosure acquires activity monitoring data of a target object; determines the effective outdoor time for the target object based on the activity monitoring data; determines the target duration and target power density of the ophthalmic optical device based on the effective outdoor time; and controls the ophthalmic optical device to perform light projection processing on the target object's eyes based on the target duration and target power density. Thus, by precisely controlling the ophthalmic optical device to perform light projection processing on the target object's eyes based on the target duration and target power density determined from the target object's activity monitoring data, the dosage and duration of light projection are ensured to meet the target object's needs, effectively improving the myopia prevention and control effect and providing a more reliable and precise guarantee for eye health.

[0035] In addition, when the light sensor detects continuous high-intensity sunlight (greater than 50,000 lux) outdoors for more than 30 minutes, it will remind users to take precautions against ultraviolet radiation.

[0036] Figure 2 This is a flowchart illustrating a control method for an eye optical device according to another exemplary embodiment.

[0037] like Figure 2 As shown, the method may include: Step 201: Obtain activity monitoring data of the target object.

[0038] Step 202: The activity monitoring data includes: activity monitoring sub-data for each sub-time period within a preset time range; for each sub-time period, the activity scene of the target object is determined based on the activity monitoring sub-data for that sub-time period; the activity scene includes outdoor scene and indoor scene.

[0039] In some embodiments, for each sub-time period, if the illuminance data is greater than or equal to a first illuminance threshold and the location data corresponds to an outdoor location, the activity scene is determined to be an outdoor scene; if the illuminance data is less than or equal to a second illuminance threshold, or if the location data corresponds to an indoor location, the activity scene is determined to be an indoor scene. In some embodiments, if the illuminance data is greater than the second illuminance threshold and less than the first illuminance threshold, it is determined whether the movement state is a non-seated state; if the movement state is a non-seated state and the location data corresponds to an outdoor location, the activity scene is determined to be an outdoor scene; if the movement state is a seated state, the activity scene is determined to be an indoor scene. Thus, through multi-dimensional data fusion analysis, the accuracy and adaptability of activity scene recognition are significantly improved.

[0040] Specifically, for each sub-time period, if the illuminance data is greater than or equal to 1000 lux and the location data corresponds to an outdoor location, the activity scene is determined to be an outdoor scene; if the illuminance data is less than or equal to 500 lux, or if the location data corresponds to an indoor location, the activity scene is determined to be an indoor scene. If the illuminance data is between 500 and 1000 lux, it is determined whether the movement state is a non-seated state; if the movement state is a non-seated state and the location data corresponds to an outdoor location, the activity scene is determined to be an outdoor scene; if the movement state is a seated state, the activity scene is determined to be an indoor scene.

[0041] Step 203: Determine the effective duration of the sub-time period based on the activity scenario and the illuminance data within the sub-time period.

[0042] In some embodiments, when the activity scene is an outdoor scene, an initial score for the sub-time period is determined based on illuminance data within the sub-time period; a score weight is determined based on the motion state within the sub-time period; a target score for the sub-time period is determined based on the initial score and the score weight; and the effective duration for the sub-time period is determined based on the target score. In some embodiments, determining the effective duration for the sub-time period based on the activity scene and illuminance data within the sub-time period further includes: when the activity scene is an indoor scene, determining the target score for the sub-time period as a specified score. Thus, by fusing scene, light intensity, and motion state, accurate dynamic calculation of the effective duration is achieved, significantly improving the accuracy of light exposure assessment in outdoor / indoor scenes.

[0043] As an example, in some embodiments, when the activity scenario is outdoor, an initial score for each sub-time period is determined based on illuminance data within that sub-time period. For instance, 100 points / hour is awarded for illuminance greater than 10,000 lux, 80 points / hour for 5,000 to 10,000 lux, and 60 points / hour for 1,000 to 5,000 lux. A score weight is determined based on the movement state within the sub-time period, with a weight of 1.2 for non-seated states and 1.0 for seated states. Based on the initial score and score weights, a target score for each sub-time period is determined, and then the target score is converted into valid duration according to certain rules. When the activity scenario is indoors, the target score for each sub-time period is determined to be a specified score (e.g., 0 points or a negative number), and is similarly converted into valid duration.

[0044] Step 204: Determine the effective outdoor time for the target object based on the effective duration within each sub-time period.

[0045] In some embodiments, the effective duration of all sub-time periods for outdoor scenes is summed to obtain the effective outdoor duration of the target object within a preset time range.

[0046] Step 205: Determine the target duration and target power density of the eye optical device based on the effective outdoor time.

[0047] Step 206: Based on the target duration and target power density, control the eye optical device to perform light projection processing on the target object's eye.

[0048] It should be noted that for a detailed description of steps 205 to 206, please refer to the relevant descriptions in other embodiments, which will not be repeated here.

[0049] The control method for an eye optical device provided in this disclosure acquires activity monitoring data of a target object. The activity monitoring data includes: activity monitoring sub-data for each sub-time period within a preset time range; for each sub-time period, the activity scene of the target object is determined based on the activity monitoring sub-data within that sub-time period; the activity scene includes outdoor and indoor scenes. Based on the activity scene and the illuminance data within the sub-time period, the effective duration within the sub-time period is determined. Based on the effective duration within each sub-time period, the effective outdoor duration of the target object is determined. Based on the effective outdoor duration, the target duration and target power density of the eye optical device are determined. Based on the target duration and target power density, the eye optical device is controlled to project light onto the eyes of the target object. This achieves dynamic and precise adaptation of the projection parameters of the eye optical device, significantly improving the scientific and personalized level of outdoor light exposure management.

[0050] Figure 3This is a flowchart illustrating a control method for an eye optical device according to another exemplary embodiment.

[0051] like Figure 3 As shown, the method may include: Step 301: Obtain activity monitoring data of the target object.

[0052] Step 302: Determine the effective outdoor time for the target object based on the activity monitoring data.

[0053] Step 303: Obtain the outdoor duration threshold.

[0054] In some embodiments, the daily target outdoor activity time can be set to a score threshold of 2400 points, which is equivalent to 120 minutes of outdoor activity. This can be converted into an outdoor time threshold (the conversion rules can be set according to the actual situation, such as conversion based on the activity quality score under different illuminance).

[0055] Step 304: Determine whether eye-projection processing is required based on the effective outdoor time and outdoor time threshold.

[0056] In some embodiments, the effective outdoor time and the outdoor time threshold are compared. If the effective outdoor time is less than the outdoor time threshold, it indicates that the target object's outdoor activities are insufficient, and it is determined that eye light projection processing is required. If the effective outdoor time is greater than or equal to the outdoor time threshold, it indicates that the target object's outdoor activities meet the standard, and it is determined that eye light projection processing is not required.

[0057] Step 305: When eye-projection processing is required, determine the target duration based on the effective outdoor duration, the projection threshold, and the duration calculation function.

[0058] As an example, when ocular light projection treatment is required, the target duration is determined based on the effective outdoor time, the light projection threshold (i.e., the supplementation rule corresponding to the activity gap mentioned above, where every 400 activity points of gap corresponds to 1 minute of PBM supplementation treatment), and the duration calculation function (a function that calculates the supplementation duration based on the activity gap, such as "supplementation duration = MIN(deficit / 400, 6)", where deficit is the activity gap). The upper limit of the target duration is 6 minutes / day.

[0059] In some embodiments, the outdoor activity integral and PBM supplement ratio are also automatically adjusted according to the season and latitude.

[0060] Step 306: Determine the target power density based on the effective outdoor duration and the power density calculation function.

[0061] As an example, the target power density can be determined based on the effective outdoor time and the power density calculation function (such as "target power density = CLAMP(20 + (deficit / 2400) × 10, 8, 50)").

[0062] In some embodiments, a target power density is determined based on the activity gap using a power density calculation function, with the target power density ranging from 8 to 50 mW / cm². Where ocular light projection processing is not required, the target duration and target power density are set to zero.

[0063] Step 307: Based on the target duration and target power density, control the eye optical device to perform light projection processing on the target object's eye.

[0064] It should be noted that for a detailed description of step 307, please refer to the relevant descriptions in other embodiments, which will not be repeated here.

[0065] The control method for an ophthalmic optical device provided in this disclosure acquires activity monitoring data of a target object; determines the effective outdoor time for the target object based on the activity monitoring data; acquires an outdoor time threshold; determines whether ophthalmic light projection treatment is needed based on the effective outdoor time and the outdoor time threshold; if ophthalmic light projection treatment is needed, determines the target time based on the effective outdoor time, the light projection threshold, and a time calculation function; determines the target power density based on the effective outdoor time and a power density calculation function; and controls the ophthalmic optical device to perform light projection treatment on the target object's eyes based on the target time and target power density. By accurately calculating the effective outdoor light exposure time through real-time acquisition of target object activity monitoring data and intelligently comparing it with a preset threshold, the phototherapy demand is automatically triggered; when intervention is needed, the target time and target power density parameters for personalized projection are calculated to ensure that the output is highly matched with the user's actual light loss and eye condition, significantly improving the scientific nature and effectiveness of eye health management.

[0066] Figure 4 This is a flowchart illustrating a control method for an eye optical device according to another exemplary embodiment.

[0067] like Figure 4 As shown, the method may include: Step 401: If no activity monitoring data is available, obtain the daily status of the target object; the daily status includes work status, school status, or holiday status.

[0068] In some embodiments, when the activity monitoring data of the target object is not obtained for some reason (such as sensor failure), the daily status information of the target object is obtained through user input or other means, such as determining whether the target object is in a working state, a school state, or a holiday state.

[0069] Step 402: Obtain the reference duration and reference power density of the target object's similar population in daily life.

[0070] In some embodiments, to accurately determine the reference duration and reference power density, a group of people of the same type as the target object can be obtained; candidate durations and candidate power densities of each person in the same group under the daily state can be obtained; and the reference duration and reference power density of the same group under the daily state can be determined based on the candidate durations and candidate power densities of each person under the daily state. This approach can fully utilize the group's data information and effectively avoid deviations caused by individual special circumstances.

[0071] As an example, the candidate durations of each individual in the daily state are averaged to obtain the reference duration; the candidate power densities of each individual in the daily state are averaged to obtain the reference power density. Therefore, averaging the candidate durations and candidate power densities of each individual in the daily state can fully utilize group data, effectively smooth fluctuations caused by individual differences, and accurately capture the central tendency of duration and power density of the same type of group in daily usage scenarios, thus obtaining highly representative and reliable reference durations and reference power densities.

[0072] As another example, based on the candidate duration and candidate power density of each individual in the daily state, the frequency of occurrence of each combination is determined; each combination includes the candidate duration and candidate power density of the same individual in the daily state; the first combination with the highest frequency of occurrence is obtained; the candidate duration in the first combination is determined as the reference duration; the candidate power density in the first combination is determined as the reference power density. This method can accurately capture the mainstream patterns of similar groups of people in daily usage scenarios. By statistically analyzing the frequency of combination occurrences, the most common and representative candidate duration and candidate power density of the group can be effectively identified, avoiding the influence of individual extreme data or outliers on the reference duration and reference power density.

[0073] Specifically, based on the target individual's daily routine, the system can retrieve reference treatment duration and reference power density for similar populations (e.g., those with similar age, gender, or region) from a pre-set database under that daily routine. For example, for school-aged children, it can retrieve the average reference duration and reference power density of PBM supplemental therapy for school-aged children of the same type. Parents can view their children's outdoor activities and PBM treatment statistics on their mobile app and set activity reminder rules.

[0074] Step 403: Determine the reference duration as the target duration and the reference power density as the target power density.

[0075] In some embodiments, in the absence of activity monitoring data, in order to ensure that the target object can still receive a certain degree of photobiological regulation, the reference duration of the same type of population is used as the target duration, and the reference power density is used as the target power density.

[0076] Step 404: Based on the target duration and target power density, control the eye optical device to perform light projection processing on the target object's eye.

[0077] In some embodiments, the PBM treatment module of the ocular optical device can be controlled to initiate treatment based on a determined target duration and target power density, thereby performing light projection processing on the eye of the target subject.

[0078] The control method for an ophthalmic optical device provided in this disclosure acquires the daily status of a target object when activity monitoring data is unavailable. This daily status includes work status, school status, or holiday status. The method acquires reference duration and reference power density for similar individuals in the target object's daily status. The reference duration is determined as the target duration, and the reference power density is determined as the target power density. Based on the target duration and target power density, the ophthalmic optical device is controlled to project light onto the target object's eyes. When activity monitoring data is missing, by identifying the target object's daily status, historical reference parameters for similar individuals are automatically retrieved as the light projection benchmark, enabling emergency phototherapy control. This ensures the availability of basic functions in abnormal situations and optimizes parameter rationality through group data, improving robustness and user experience.

[0079] Figure 5 This is a schematic diagram of the structure of a control device for an eye optical device according to an exemplary embodiment.

[0080] like Figure 5 As shown, the control device 500 of the eye optical device includes: a first acquisition module 501, a first determination module 502, a second determination module 503, and a projection processing module 504.

[0081] The system includes a first acquisition module 501 for acquiring activity monitoring data of the target object; a first determination module 502 for determining the effective outdoor time of the target object based on the activity monitoring data; a second determination module 503 for determining the target duration and target power density of the eye optical device based on the effective outdoor time; and a projection processing module 504 for controlling the eye optical device to perform light projection processing on the eyes of the target object based on the target duration and the target power density.
