Description

Technical Field

[0001] This application relates to the field of intelligent lighting technology, and in particular to a dynamic photo-eye adjustment training method and related device for relieving eye fatigue. Background Technology

[0002] Myopia in adolescents has become a global public health problem. The occurrence and progression of myopia are closely related to the functional state of the eye's accommodative system. Accommodation is mainly controlled by the ciliary muscle; prolonged close-range eye use leads to continuous tension in the ciliary muscle, which is a significant factor in the occurrence and development of myopia. Providing regularly changing, dynamically varying light stimulation to induce active contraction and relaxation of the ciliary muscle is considered an effective means to improve accommodative function and slow the progression of myopia. Existing eye training methods sometimes employ alternating switching of fixed brightness levels. This switching process is non-continuous and abrupt, resulting in extremely high brightness changes with each switch, posing a risk of exceeding illuminance safety standards. Furthermore, abrupt switching significantly impacts eye comfort. In addition, some eye training methods use a single, fixed-frequency, fixed-amplitude sine wave dimming. While this provides a smooth brightness gradient, the constant amplitude throughout lacks macroscopic variation, easily leading to adaptation effects and diminishing training effectiveness over time. Moreover, a single frequency cannot simultaneously cover the accommodative stimulation needs of different time scales. Summary of the Invention

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various implementations. Simultaneously, the steps or actions described in the method description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed.

[0018] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0019] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0020] The present invention relates to a dynamic optical eye accommodation training method and related device for relieving eye strain. During training, the method first involves gradual adaptation to varying light levels, causing the pupils to constrict / dilate autonomously, thus exercising the iris muscles and improving adaptability to day / night and indoor / outdoor transitions, alleviating pupil stiffness caused by prolonged screen time. Next, fixed-point brightness switching is performed, using multiple brightness levels to coordinate with focused vision, engaging the ciliary muscles and pupils to improve eye strain and blurred vision. Finally, gradual light changes are synchronized with breathing, promoting relaxation of both the mind and eyes, relieving tension-type eye strain and dry eyes. Therefore, in practical applications, providing regularly changing dynamic light stimulation is considered an effective means of improving accommodative function and slowing myopia progression.

[0021] Referring to relevant domestic and international standards for myopia prevention lighting (including technical requirements such as GB / T39363) and existing research results, the key parameter constraints for dynamic lighting training equipment include: a dynamic illuminance range of 300–3500 lx to ensure the light brightness covers the effective training illuminance range; a brightness change rate of ≤10% per 0.1s to prevent flicker damage and ensure visual safety; a peak / valley ratio of >2 to ensure effective adjustment of the stimulus amplitude; a duty cycle of <10% for low illuminance (<100 lx) to prevent prolonged periods of darkness; a duty cycle of <10% for high change rate (>5% / 0.1s) to limit the proportion of high-speed change time; and at least one significant change within 30 minutes to ensure the richness of training. In existing technologies, some products lack precise mathematical models for their dynamic lighting algorithms, making it impossible to guarantee that key indicators such as the illuminance change rate and peak / valley ratio consistently meet safety technical specifications throughout the entire training period (typically 30 minutes), resulting in poor consistency in engineering implementation.

[0022] Based on the above, embodiments of the present invention provide a dynamic optical eye accommodation training method and related apparatus for relieving eye fatigue. The method controls the operation of a light-emitting component according to preset initial illumination parameters, including an upper limit value for brightness, a lower limit value for brightness, and an update cycle. In response to a training start command, the method enters a training mode and begins timing, acquiring the timing duration. A brightness variation factor is calculated based on the timing duration. The current brightness value is determined based on the upper limit value, lower limit value, and brightness variation factor. The light-emitting component is then controlled to operate according to the update cycle based on the current brightness value. By dynamically adjusting the current brightness value through the brightness variation factor, the actual amplitude of the light-emitting component's brightness within the update cycle continuously changes with the macroscopic envelope, forming a wide-range regulatory stimulus gradient. This avoids the sensory adaptation effect caused by a single fixed amplitude stimulus, thereby improving the eye training effect.

[0023] Please see Figure 1 , Figure 1 The flowchart illustrates a dynamic optical eye accommodation training method for relieving eye strain provided by an embodiment of the present invention. For example... Figure 1 As shown, the dynamic optical eye accommodation training method for relieving eye strain according to an embodiment of the present invention includes the following steps: Step S1000: Control the light-emitting components to work according to the preset initial lighting parameters, which include the upper limit of brightness, the lower limit of brightness, and the update cycle.

[0024] Understandably, before eye training begins, it is necessary to set the initial illumination parameters of the light-emitting components, including the upper limit of brightness. , lower limit of brightness and update cycle . Specifically, , In this embodiment, the rapid adjustment cycle for brightness is 50 seconds. During this time, the light-emitting component can be either off or illuminated at a specified brightness when entering training mode.

[0025] It should be noted that the update cycle This refers to the time interval at which the light-emitting components update their brightness values, typically in the millisecond range, to ensure a smooth transition of lighting parameters.

[0026] Step S2000: In response to the training start command, enter the training mode and start timing, and obtain the timing duration.

[0027] Understandably, upon receiving the training start command, in order to accurately adjust the brightness of the light-emitting components by tracking the duration of training mode, it is necessary to start timing simultaneously upon entering training mode and obtain the timing duration in real time. It should be noted that the timing duration... This represents the number of milliseconds elapsed after entering training mode.

[0028] Please see Figure 2 , Figure 2 A schematic diagram illustrating the specific implementation process of step S2000 above is shown. For example... Figure 2 As shown, step S2000 includes at least the following steps: Step S2100: When the timer reaches the preset waiting time.

[0029] It's understandable that eye training is a cyclical process; after each training session, training needs to pause and wait for a preset waiting time before the next session can begin. Therefore, to ensure the training process runs cyclically, the system can automatically trigger the training start command when the preset waiting time has elapsed after the previous session ends, or, if the training duration is 30 minutes and the break time is 30 minutes, the system can automatically trigger the training start command on the hour.

[0030] Step S2200: The user presses the training button to issue a training start command.

[0031] Understandably, in practical applications, users may need to manually activate the training mode due to visual or lifestyle requirements. When a user needs eye training, pressing the training button will activate the dynamic optical eye accommodation training device to relieve eye strain and execute the following steps. By setting the training button, the flexibility and compatibility of the dynamic optical eye accommodation training method for relieving eye strain are effectively improved, allowing for immediate entry into training mode based on user needs, thus enhancing the user experience.

[0032] Step S3000: Calculate the brightness change factor based on the timing duration.

[0033] Understandably, during training, in order to dynamically adjust the brightness of the light-emitting components, it is necessary to calculate the brightness change factor in real time based on the timing duration. In practical applications, based on the cosine function, a first cosine change factor is determined as the slow envelope factor of the dynamic photodynamic accommodation training method to alleviate eye strain. This controls the speed, smoothness, and curve shape of brightness changes, achieving a slow, gentle, and non-jumping dimming effect, thus adapting to dynamic photodynamic accommodation training to alleviate eye strain.

[0034] Please see Figure 3 , Figure 3 A schematic diagram illustrating the specific implementation process of step S3000 in another embodiment is shown. For example... Figure 3 As shown, step S3000 further includes at least the following steps: Step S3100: Calculate the first cosine variation factor based on the timing duration.

[0035] It is understandable that the above steps are used to obtain the timing duration. Then, by substituting into the cosine function, the first cosine change factor is obtained as shown in the following formula:

[0036] Among them, 900000ms is 15 minutes, which is the slow envelope half-cycle of brightness adjustment, that is, the total duration of a single training process. The duration is 30 minutes. Of course, in other embodiments, the slow envelope half-cycle can also have other durations; for example, the slow envelope half-cycle could be 600,000 ms, or 10 minutes, making the total duration of a single training process 30 minutes. It takes 20 minutes.

[0037] Step S3200: Normalize the first cosine variation factor to obtain the brightness variation factor.

[0038] Understandably, normalization is a numerical transformation that maps the original physical or control quantity to a fixed standard range. Specifically, it linearly normalizes the first cosine variation factor to [0, 100] (percentage) to more accurately correspond to the pulse width modulation (PWM) duty cycle or brightness level. Specifically, the normalized brightness variation factor... As shown in the formula below:

[0039] It should be noted that the change factor It refers to the normalization coefficient used to dynamically adjust the brightness value based on the timing duration. Its value range is usually [0,1] or [-1,1], and it can be calculated by periodic functions (such as cosine function, sine function, etc.).

[0040] Step S4000: Determine the current brightness value based on the upper limit value, lower limit value, and brightness change factor.

[0041] Understandably, after obtaining the brightness change factor, in order to avoid the brightness value being too high or too low, it is necessary to combine the upper limit value and the lower limit value of brightness to determine the current brightness value.

[0042] Please see Figure 4 , Figure 4 A schematic diagram illustrating the specific implementation process of step S4000 above is shown. For example... Figure 4 As shown, step S4000 includes at least the following steps: Step S4100: Determine the dynamic upper limit value based on the upper limit value, lower limit value, and brightness change factor.

[0043] Understandably, after obtaining the brightness change factor through the above steps, a dynamic upper limit value needs to be determined to ensure that the current brightness value can be accurately controlled between the upper and lower limits. Specifically, the dynamic upper limit value... The calculation formula is as follows:

[0044] From the above formula, it can be seen that when the brightness change factor... When the maximum value is 1, the dynamic upper limit value When the brightness change factor When the minimum value is 0, the dynamic upper limit value As can be seen, the dynamic upper limit value It can effectively control the current brightness value between the upper and lower brightness limits, and through the brightness variation factor Adjust dynamically.

[0045] Step S4200: Determine the current brightness value based on the dynamic upper limit value, the brightness upper limit value, and the timing duration.

[0046] As can be understood from the above, after obtaining the dynamic upper limit value and the brightness upper limit value, the current brightness value can be accurately determined based on the interval in which the timing duration is located.

[0047] Please see Figure 5 , Figure 5 A schematic diagram illustrating the specific implementation process of step S4200 above is shown. For example... Figure 5 As shown, step S4200 includes at least the following steps: Step S4210: Determine the timing phase in which the timing duration is located based on the timing duration and update cycle.

[0048] As can be understood, phase describes the relative position or offset of periodic waveforms of the same frequency on the time axis. To precisely adjust brightness, it is necessary to determine the timing phase corresponding to the timing duration based on the timing duration and update cycle. The calculation formula is as follows:

[0049] Step S4220: Calculate the second cosine variation factor based on the timing phase.

[0050] It is understandable that, consistent with step S3100 above, the timing phase is obtained in the above steps. Then, by substituting the cosine function, the second cosine variation factor is obtained as shown in the following formula:

[0051] In the above formula, 50000ms is 50s, which corresponds to the update cycle.

[0052] Of course, in other embodiments, the second cosine variation factor can also be calculated using a sine function, as shown in the following formula:

[0053] Step S4230: Obtain the current brightness value based on the dynamic upper limit value, the brightness upper limit value, and the second cosine change factor.

[0054] It is understandable that, consistent with step S3200 above, the second cosine variation factor is normalized and combined with the dynamic upper limit value. upper limit of brightness Get the current brightness value The calculation formula is as follows:

[0055] Step S5000: Control the operation of the light-emitting components according to the current brightness value and the update cycle.

[0056] Please see Figure 8 , Figure 8 A graph showing the current brightness value obtained from the above steps is displayed. Figure 8 As shown, the blue curve represents the curve change of the current brightness value, i.e., the range of rapid small-cycle fluctuations; the orange curve represents the slow envelope graph; and the green dashed line represents the lower limit of brightness. It should be noted that the dynamic photodynamic accommodation training method for relieving eye strain in this embodiment uses a 50-second update cycle to ensure the timing duration is accurate to an integer millisecond, avoiding floating-point drift. Specifically, within a 50-second fast-wave cycle, the change process of the dynamic upper limit value includes a 25-second decrease and a 25-second increase. Within each fast-wave cycle, the brightness sinusoidally decreases from the current upper envelope limit to 40% of the lower brightness limit (25 seconds), and then sinusoidally increases back to 100% of the upper brightness limit (25 seconds), completing one complete accommodation stimulus. Figure 8 As shown, there are 36 complete fast wave cycles in 30 minutes. Of course, in other embodiments, the lower limit of brightness can be other values, such as 30%.

[0057] It is understandable that, such as Figure 8 As shown, within a 30-minute training cycle, the brightness change rate consistently remained ≤10%, meeting relevant safety standards and ensuring compliance. Secondly, the measured upper limit of brightness was 100%, the lower limit was 40%, and the peak / valley ratio of the current brightness value was 2.5, providing an effective stimulus gradient. Furthermore, the double-layer superimposed waveform remained stable during continuous operation, without abrupt changes or jitter, ensuring the waveform stability of the brightness change rate curve. The double-layer superimposed waveform refers to a composite waveform formed by multiplying a fast, small-cycle waveform (such as a sine wave) with a slow envelope waveform (such as a cosine wave), used to simultaneously generate both rapid microscopic changes and slow macroscopic changes.

[0058] Understandably, after obtaining the current brightness value, the light-emitting components are controlled to work according to the update cycle until the timing duration exceeds the total training time, i.e.:

[0059] Please see Figure 6 , Figure 6 A schematic diagram illustrating the specific implementation process of step S5000 above is shown. For example... Figure 6 As shown, step S5000 includes at least the following steps: Step S5100: Perform amplitude limiting processing on the current brightness value to obtain the amplitude-limited brightness value.

[0060] Understandingly, clipping / limiting clamps values ​​that exceed a preset range after calculation, forcibly fixing them at their upper and lower boundaries to prevent parameter overflow, hardware malfunctions, excessively bright lights, or complete darkness. This is because during slow envelope, exponential curve, or floating-point iterative calculations, the calculated brightness value may be negative or greater than 1 due to the influence of coefficients; without clipping, brightness would be erratic. Clipping the current brightness value yields a limited brightness value, forcibly locking the upper and lower limits of the current brightness value. In the event of misoperation or instruction errors, the light will not be too bright or completely dark, thus adapting to dynamic photodynamic training to alleviate eye strain.

[0061] Step S5200: Convert the limiting brightness value into the corresponding PWM duty cycle value and input it into the PWM channel.

[0062] Understandably, after determining the brightness limit value, the percentage of brightness needs to be converted into a PWM duty cycle to obtain the PWM duty cycle value. To facilitate precise control of the light component's brightness, the PWM duty cycle value needs to be input into the PWM channel. The PWM channel is a hardware port on a microcontroller or driver chip that independently outputs one PWM waveform. Each channel can be individually configured with the following parameters: frequency, duty cycle, phase, and enable. Since this embodiment only addresses brightness adjustment, only a single channel is needed to precisely control the brightness of the light-emitting component; that is, only one PWM output is used to drive a single light-emitting component.

[0063] Step S5300: Control the operation of the light-emitting component according to the update cycle and the PWM duty cycle value.

[0064] Understandably, after obtaining the PWM duty cycle values ​​for each update cycle according to the above steps, the light-emitting component is controlled to operate. Specifically, since LED light-emitting components are current-driven devices, their brightness is approximately proportional to the average operating current. Therefore, PWM, through a fixed-frequency square wave, changes the on-time within one cycle by altering the PWM duty cycle value, effectively changing the average current or average power, thereby continuously adjusting the brightness of the light-emitting component. In practical applications, controlling the light-emitting component's operation according to the update cycle using PWM duty cycle values ​​is existing technology and will not be elaborated upon here.

[0065] Please see Figure 7 , Figure 7 A schematic diagram illustrating the specific implementation process of step S5000 in another embodiment is shown. For example... Figure 7 As shown, step S5000 includes at least the following steps: Step S5400: When the timing duration reaches the preset duration threshold, control the light-emitting component to work according to the upper limit of brightness, and clear the timing duration.

[0066] Understandably, when the timer reaches the preset threshold, i.e., 30 minutes, a complete eye training session is finished. At this point, to avoid fatigue from repeated eye training, the light-emitting component needs to be controlled to exit training mode and operate according to the upper limit of brightness. Simultaneously, to facilitate timely entry into the next eye training session, the timer needs to be cleared for re-timing and statistics in the next session.

[0067] Step S5500: When the timer reaches the preset waiting time, re-enter the training mode.

[0068] Understandably, when the timer reaches the preset waiting time, that is, the cumulative time since the last eye training session has reached the waiting time, for example, a waiting time of 30 minutes, it is necessary to re-enter the training mode in order to avoid fatigue and discomfort caused by prolonged use of the eyes.

[0070] The light-emitting module 610 is used to control the operation of the light-emitting components according to preset initial lighting parameters, including upper limit value of brightness, lower limit value of brightness and update cycle. The timing module 620 is used to respond to the training start command, enter the training mode and start timing, and obtain the timing duration; The calculation module 630 is used to calculate the brightness change factor based on the timing duration; The determination module 640 is used to determine the current brightness value based on the upper limit value of brightness, the lower limit value of brightness, and the brightness change factor; The training module 650 is used to control the operation of the light-emitting components according to the current brightness value and the update cycle.
