Description

Technical Field

[0001] This application relates to the field of photobiological regulation technology, and in particular to a photobiological regulation method and device for relieving regulatory spasm. Background Technology

[0002] Accommodative spasm refers to a persistent state of accommodative tension caused by excessive contraction of the ciliary muscle, manifesting as decreased distance vision, fluctuating myopia, and eye strain. Accommodative spasm is very common among students who work at close range for long periods and those working with VDTs (Visual Display Terminals), and is a major cause of pseudomyopia.

[0003] Prolonged accommodative spasm may promote the development of true myopia. Timely relief of accommodative spasm and restoration of normal ciliary muscle function are of great significance for preventing myopia and improving visual comfort.

[0004] Traditional methods for relieving accommodative spasm include gazing into the distance, using cycloplegic agents (such as atropine), and visual training. However, gazing into the distance is limited by environmental factors, medications have side effects, and training adherence is poor. Therefore, how to safely and effectively relieve accommodative spasm is a pressing issue that needs to be addressed. Summary of the Invention

Detailed Implementation

[0012] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0013] Figure 1 A flowchart illustrating the steps of a photobiological modulation method for relieving accommodative spasm provided in this application embodiment is shown below. Figure 1 As shown, the photobiological regulation method for relieving regulatory spasm may include steps 101 to 103.

[0014] Step 101: Determine the appropriate adjustment mode for the user based on the user's adjustment spasticity index obtained from the assessment.

[0015] In this embodiment, the accommodative spasm index is a quantitative index calculated based on the user's eye accommodation function-related detection parameters (accommodative amplitude, accommodation flexibility, accommodation hysteresis, refractive power in dark room, and ciliary muscle thickness). It is used to assess the severity of excessive ciliary muscle contraction and is the core basis for determining the accommodation mode.

[0016] The regulation mode refers to two photobiological regulation modes classified according to the regulation spasticity index, including the relief mode (suitable for users with more severe spasticity) and the prevention mode (suitable for users with milder spasticity or those who only need routine maintenance).

[0017] When relieving dysregulation in users, the dysregulation index of the user can be obtained, and the appropriate dysregulation mode for the user can be determined based on the index.

[0018] In the specific implementation, firstly, relevant detection parameters of the user's eyes can be collected: the accommodative amplitude is measured using the push-up method or the negative lens method, the accommodative flexibility is tested using a ±2.00D flip lens, accommodative lag is detected through open-field autorefraction, refractive power is measured in a dark room to eliminate accommodative interference, and ciliary muscle thickness is measured using UBM (Ultrasound Biomicroscopy). Then, based on all the above-collected detection parameters, the user's accommodative spasm index is calculated using a preset algorithm. Finally, the accommodative spasm index is compared with a preset index threshold to determine the accommodative mode suitable for the user. This implementation process will be combined with the following embodiments. Figure 2 and Figure 3 A detailed description will not be repeated here.

[0019] After determining the appropriate conditioning mode for the user based on the user's conditioning spasticity index obtained from the assessment, step 102 is performed.

[0020] Step 102: Determine the optical power density and adjustment duration corresponding to the user according to the adjustment mode.

[0021] Optical power density refers to the intensity of light energy projected per unit area, measured in milliwatts per square centimeter. It is a core parameter for photobiological regulation, with different regulation modes corresponding to different power density ranges.

[0022] The duration of regulation refers to the duration of a single photobiological regulation, which is matched with the light power density to ensure that the light energy can relieve spasms without irritating the eyes.

[0023] After determining the appropriate adjustment mode for the user, the corresponding light wave power density and adjustment duration can be determined based on the adjustment mode. Specifically, if the determined adjustment mode is the relief mode (suitable for users with more severe spasms), the corresponding light wave power density is set to 35-45 milliwatts per square centimeter, the adjustment duration is 5 minutes, and a distant gazing relaxation step is included. If the determined adjustment mode is the prevention mode (suitable for users with milder spasms or for daily maintenance), the corresponding light wave power density is set to 20-30 milliwatts per square centimeter, the adjustment duration is 3 minutes, and no additional distant gazing step is required.

[0024] Meanwhile, the light wavelength is fixed as a combination of red light 630-680nm and near-infrared light 810-850nm, with the optimal combination of 660nm red light and 830nm near-infrared light being preferred to ensure the photobiological regulation effect.

[0025] Step 103: Using a dual-wave projection method, perform photobiological conditioning on the user according to the light power density and the adjustment duration.

[0026] Dual-wave projection refers to the projection method that simultaneously projects red light (630-680nm) and near-infrared light (810-850nm). The two light waves work together to improve superficial blood flow and promote relaxation of deep ciliary muscles, respectively.

[0027] Photobiological modulation refers to a non-invasive modulation method that uses red and near-infrared light of specific wavelengths and power densities to project onto the corresponding area of ​​the ciliary muscle in the eye, promoting ciliary muscle relaxation, improving ocular microcirculation, and thus alleviating accommodative spasm. Photobiological modulation can promote muscle relaxation, improve microcirculation, and reduce oxidative stress. Applying PBM to the ciliary muscle may promote relaxation and alleviate accommodative spasm by improving its metabolic state and neural regulation.

[0028] After determining the light power density and accommodation duration, a dual-wave projection method can be used to perform photobiological accommodation on the user according to the light power density and accommodation duration. Specifically, the projection angle and position of the phototherapy device can be adjusted to ensure that the projection area is precisely aligned with the annular area 1-3mm behind the limbus of the user's eye (the anatomical location corresponding to the ciliary muscle). Then, the dual-wave projection function is activated, simultaneously projecting red light and near-infrared light, with the projected light spot being annular (inner diameter 8mm, outer diameter 14mm), and the light power density maintained at the value determined in step 102. Projection continues until the accommodation duration determined in step 102 is reached, at which point the projection automatically terminates, completing a single photobiological accommodation. If, during phototherapy, the user's refractive error is monitored in real time and drifts towards hyperopia to a preset standard, the projection can be terminated early.

[0029] In this embodiment of the application, the relaxation effect is monitored and adjusted in real time through open-field automatic refraction during the treatment process.

[0030] This application can be used in ophthalmology hospitals, optometry centers, and school health clinics. The system can be designed as a desktop or portable device, suitable for daily use by students and office workers. Targeting high-risk groups for pseudomyopia and eye strain, the market demand is clear, and it has good prospects for widespread application. It can provide a safe and effective non-pharmacological treatment for accommodative spasm and pseudomyopia.

[0031] This application embodiment accurately classifies accommodative spasm by calculating the accommodative spasm index, matches relief or prevention modes as needed, and limits the power density and duration of the dual-wavelength light ring to achieve targeted photobiological modulation of the ciliary muscle. It can safely and efficiently relax the over-contracted ciliary muscle and quickly relieve accommodative spasm, while maintaining normal ocular metabolic function through daily prevention mode, thereby achieving the technical effect of relieving accommodative spasm in a comprehensive, safe and effective manner.

[0032] Next, combined Figure 2 The calculation process for the regulation spasticity index and the implementation process for determining the regulation mode are described in detail.

[0033] Reference Figure 2 The diagram illustrates a flowchart of the adjustment mode determination method provided in an embodiment of this application. Figure 2 As shown, the method for determining the adjustment mode may include steps 201 to 203.

[0034] Step 201: Collect the user's adjustment amplitude measurement value, adjustment flexibility, adjustment hysteresis value, refractive power under dark room and ciliary muscle thickness measurement value.

[0035] In this embodiment, the adjustment range measurement value refers to the maximum adjustment range that the user's ciliary muscle can complete, which is measured by a specific detection method (propulsion method or negative lens method). It is a basic parameter for evaluating the ciliary muscle's contraction ability.

[0036] Accommodative flexibility refers to the ability of the user's ciliary muscle to quickly switch between tense and relaxed states. In this example, it was obtained through a ±2.00D flip mirror test, reflecting the accommodative flexibility of the ciliary muscle.

[0037] Accommodation hysteresis is a value obtained through open-field autorefraction. It refers to the difference between the actual accommodation state and the ideal accommodation state when a user is looking at a distant object, and is used to reflect the degree of relaxation of the ciliary muscle.

[0038] Darkroom refractive power refers to the user's true refractive power measured in a dark room environment (excluding interference from the eye's own accommodation), providing a benchmark reference for calculating the accommodative spasm index.

[0039] The ciliary muscle thickness measurement refers to the actual thickness value of the ciliary muscle obtained by ultrasound biomicroscopy. It is used to determine the degree of congestion and tension of the ciliary muscle and to help assess the severity of accommodative spasm.

[0040] When performing photobiological conditioning on users, measurements of the user's accommodative amplitude, accommodative flexibility, accommodative hysteresis, refractive power in a dark room, and ciliary muscle thickness can be collected. The specific data collection process may include: Accommodation amplitude measurement: Either the advancing method or the negative lens method is used. The advancing method involves having the user fixate on the standard optotype and slowly moving it closer until it is just barely discernible. The distance between the optotype and the eyeball at this point is recorded, and the accommodation amplitude measurement value is calculated. The negative lens method involves gradually adding a negative lens in front of the user's eyes until the optotype becomes blurred, and the accommodation amplitude measurement value is calculated based on the lens power.

[0041] Adjustment flexibility data collection: Using a ±2.00D flip lens, the user continuously looks at a standard target at 5 meters, and the lens is quickly flipped. The number of times the user can clearly identify the target per minute is recorded as a quantitative value of adjustment flexibility.

[0042] Accommodation hysteresis value acquisition: Using an open-field automatic refractometer, the user is allowed to naturally gaze at a distant target. The instrument automatically reads the user's refractive power value at this time and compares it with the refractive power in a dark room to calculate the accommodation hysteresis value.

[0043] Darkroom refractive error measurement: The user is placed in a darkroom environment and allowed to relax completely (rest for 5-10 minutes). The user's refractive error is then measured using an optometry device. This is the darkroom refractive error measurement.

[0044] Ciliary muscle thickness measurement: The user's eye is scanned using an ultrasonic biomicroscope, focusing on the area where the ciliary muscle is located. The instrument automatically collects and outputs the thickness measurement value of the ciliary muscle, ensuring that the measurement location is at the thickest point of the ciliary muscle and guaranteeing data accuracy.

[0045] After collecting the user's adjustment amplitude measurement, adjustment flexibility, adjustment hysteresis value, refractive power under dark room and ciliary muscle thickness measurement, step 202 is executed.

[0046] Step 202: Calculate the accommodation spasm index based on the measured values ​​of the accommodation amplitude, the accommodation flexibility, the accommodation hysteresis, the refractive power in the dark room, and the ciliary muscle thickness.

[0047] After collecting measurements of the user's accommodative amplitude, accommodative flexibility, accommodative hysteresis, refractive power under dark chamber, and ciliary muscle thickness, the accommodative spasm index can be calculated based on these measurements. Specifically, the five collected parameters are first standardized to eliminate dimensional differences and ensure consistent weighting of each parameter, preventing any single parameter from excessively influencing the calculation results. Then, based on clinical validation data, corresponding weights are assigned to the five parameters (ciliary muscle thickness and accommodative hysteresis have the highest weights, followed by accommodative amplitude and accommodative flexibility, with refractive power under dark chamber serving as the baseline weight). Afterward, the preprocessed parameters are multiplied by their corresponding weights, summed, and then converted using a preset algorithm (linear fitting or nonlinear regression) to obtain the standardized accommodative spasm index. A higher index value indicates a more severe degree of accommodative spasm in the user.

[0048] After calculating the regulation spasticity index, proceed to step 203.

[0049] Step 203: Determine the user-suitable adjustment mode based on the spasticity index.

[0050] After obtaining the accommodative spasticity index, the appropriate adjustment mode for the user can be determined based on the index. Specifically, the accommodative spasticity index can be compared with an index threshold to determine the final adjustment mode based on the comparison result.

[0051] This application embodiment collects eye accommodation-related parameters from multiple dimensions, accurately calculates the accommodation spasm index, and matches an appropriate accommodation mode accordingly. This enables accurate assessment and classification of the user's accommodation spasm level, providing a scientific basis for subsequent safe and efficient photobiological regulation, effectively avoiding the problems of blind phototherapy, and helping to relieve accommodation spasm and improve ocular visual function.

[0052] Next, combined Figure 3 The implementation process of determining the final adjustment mode by combining the exponential threshold is described in detail.

[0053] Reference Figure 3 The diagram illustrates a flowchart of another adjustment mode determination method provided in an embodiment of this application. Figure 3As shown, the adjustment mode determination method includes steps 301 and 302.

[0054] Step 301: If the spasticity index is greater than or equal to the index threshold, determine that the user-adapted adjustment mode is the relief mode.

[0055] In this embodiment, the index threshold can be a preset threshold based on a large amount of clinical validation data, used to distinguish the severity of regulatory spasticity. It can be fine-tuned according to the physiological characteristics of different groups such as students and VDT workers, and is the core reference standard for determining the regulatory mode.

[0056] The relief mode refers to a photobiological modulation mode adapted for users with severe accommodative spasm. It uses high-power-density dual-wavelength light projection to quickly relax the over-contracted ciliary muscle and relieve symptoms related to accommodative spasm.

[0057] After obtaining the accommodative spasm index, a preset index threshold can be retrieved (this threshold is pre-stored in the system and can be dynamically fine-tuned according to clinical application scenarios). The system automatically compares the accommodative spasm index with the index threshold. If the accommodative spasm index is greater than or equal to the index threshold, the user is diagnosed with severe accommodative spasm, and the ciliary muscle is in a state of significant overcontraction and congestion, requiring rapid relief of spasm symptoms. Based on the above determination, the system automatically determines the appropriate accommodation mode for the user as the relief mode and simultaneously records the mode determination result, feeding it back to the phototherapy parameter setting module to provide a basis for subsequent matching of light power density and accommodation duration.

[0058] Step 302: If the regulation spasticity index is less than the index threshold, determine that the regulation mode adapted to the user is the prevention mode.

[0059] The prevention mode is a photobiological accommodation mode suitable for users with mild accommodative spasm or those who only need routine eye maintenance. It maintains the normal function of the ciliary muscle and reduces the risk of recurrence of accommodative spasm by projecting dual-wavelength light with a low power density.

[0060] If the accommodative spasm index is determined to be less than the index threshold, the user is diagnosed with mild accommodative spasm or only has ciliary muscle fatigue. High-intensity relief is not necessary; the focus should be on daily maintenance and prevention. Based on this determination, the system automatically identifies the appropriate accommodative mode as the prevention mode, records the mode determination result, and feeds it back to the phototherapy parameter setting module. This ensures that subsequent phototherapy parameters are adapted to daily preventative needs and avoids over-phototherapy.

[0061] This application embodiment achieves scientific classification of adjustment modes by accurately comparing the spasticity index with a preset threshold, enabling users with severe spasticity to receive targeted relief treatment, and users with mild spasticity or those requiring prevention to receive appropriate maintenance treatment. This ensures that the adjustment mode is accurately matched with the user's spasticity level, improves the targeting and effectiveness of photobiological regulation, and avoids the waste of resources or poor results caused by blind phototherapy.

[0062] Next, combined Figure 4 The process of achieving photobiological modulation by synchronously projecting dual wavelengths is described in detail.

[0063] Reference Figure 4 The diagram illustrates a flowchart of a photobiological regulation method provided in an embodiment of this application. Figure 4 As shown, the photobiological regulation method may include steps 401 and 402.

[0064] Step 401: Based on the light power density, and using the annular light spot formed by the synchronously projected red light and near-infrared light combination, perform photobiological modulation on the annular area 1-3mm behind the corneal limbus of the user's ciliary muscle.

[0065] In this embodiment, the 1-3mm annular region behind the limbus refers to the precise anatomical region corresponding to the ciliary muscle of the user's eye. It is located 1-3mm behind the limbus (the boundary between the cornea and sclera) and is distributed in a ring shape. It is the target area for photobiological regulation, ensuring that light waves can be precisely applied to the ciliary muscle.

[0066] Red light refers to visible light with a wavelength range of 630-680nm (preferably 660nm), which can improve microcirculation in the surface of the eye and help relieve ciliary muscle fatigue.

[0067] Near-infrared light refers to invisible light with a wavelength range of 810-850nm (preferably 830nm). It can penetrate the surface tissue of the eye and reach the ciliary muscle, promoting ciliary muscle relaxation and relieving accommodation spasm.

[0068] The ring-shaped light spot refers to the ring-shaped light signal formed by the synchronous projection of red light and near-infrared light. The inner diameter of the light spot is 8mm and the outer diameter is 14mm. It is adapted to the ring-shaped area 1-3mm behind the limbus of the cornea to ensure targeted coverage of the ciliary muscle and avoid the light waves from irradiating other sensitive areas of the eye.

[0069] During light wave projection, the previously determined light wave power density parameters can be used (35-45 milliwatts per square centimeter for relief mode, and 20-30 milliwatts per square centimeter for prevention mode). The red light wavelength is set to 660nm and the near-infrared light wavelength to 830nm. The dual-wave synchronous projection function is then adjusted to ensure stable and synchronized output of both light waves. The user is guided to maintain a seated posture with eyes naturally looking straight ahead, adjusting the projection angle and distance of the phototherapy device (keeping a distance of 15-20cm from the eyes). Using the device's built-in positioning module, the annular light spot is precisely aligned with the annular area 1-3mm behind the corneal limbus of the ciliary muscle, ensuring complete coverage of the target area without deviation or omission. Finally, dual-wave synchronous projection can be performed: The projection switch is activated, and the device simultaneously projects red and near-infrared light onto the target area. The two light waves superimpose to form an annular light spot. During projection, the light wave power density is monitored in real time to ensure it remains stable at the preset value, preventing power fluctuations from affecting the phototherapy effect or damaging the eyes.

[0070] Step 402: Continue projection until the light wave projection duration reaches the specified adjustment duration, then terminate the photobiological adjustment process.

[0071] The light wave projection duration refers to the actual duration for which the phototherapy device projects dual-wavelength light onto the user's eyes. It must be consistent with the preset adjustment duration and is a key parameter for controlling light energy intake.

[0072] Photobiological modulation process refers to a complete operation process aimed at relieving accommodative spasm by using targeted projection of dual-wavelength light with specific wavelengths and power densities to relax the ciliary muscle. It includes steps such as spot positioning, dual-wave projection, duration control, and process termination.

[0073] The phototherapy device has a built-in timing module that starts timing from the moment dual-wave projection begins, recording the projection duration in real time and comparing it with the preset adjustment duration (5 minutes for relief mode and 3 minutes for prevention mode). When the timing module shows that the projection duration has reached the preset adjustment duration, the device automatically shuts down the dual-wave projection function and stops projecting light waves to the eyes. If any eye discomfort is detected during projection (such as abnormal blinking frequency or abnormal refractive error), a manual termination command can be triggered to end the process early. After termination, the device automatically records the key parameters of this phototherapy session (light power density, actual projection duration, and light spot positioning) and prompts the user to close their eyes and rest for 1-2 minutes to help the ciliary muscle relax and ensure maximum phototherapy effect.

[0074] This embodiment of the application precisely sets the light power density, targeting a ring-shaped light spot formed by combining red and near-infrared light onto the corresponding area of ​​the ciliary muscle. Combined with a preset adjustment duration to control light energy intake, it achieves precise and gentle photobiological modulation of the ciliary muscle. This quickly relaxes over-contracted ciliary muscles and relieves accommodative spasm, while avoiding light irradiation of sensitive areas of the eye, ensuring the safety of phototherapy. Combined with the scientific classification of adjustment modes described above, it further enhances the targeting and effectiveness of photobiological modulation, avoids the drawbacks of indiscriminate phototherapy, and helps improve the user's visual comfort.

[0075] Next, combined Figure 5 The photobiological modulation process of alternating light wave projection is described in detail.

[0076] Reference Figure 5 The diagram illustrates a flowchart of another photobiological regulation method provided in an embodiment of this application. Figure 5 As shown, the photobiological regulation method may include steps 501 and 502.

[0077] Step 501: Based on the light power density, and using the annular light spot formed by the alternating projection of red and near-infrared light, perform photobiological modulation on the annular region 1-3 mm behind the corneal limbus of the user's ciliary muscle.

[0078] In this embodiment, alternating projection refers to the method of alternating projection of light and near-infrared light at a preset frequency. The two light waves do not overlap and cycle in an orderly manner, ensuring that the ciliary muscle receives the effects of the two light waves respectively, while avoiding the problem of excessive energy caused by the superposition of the two waves.

[0079] During light wave projection, the previously determined light wave power density parameters can be used (35-45 milliwatts per square centimeter for relief mode, and 20-30 milliwatts per square centimeter for prevention mode). The red light wavelength is set to 660nm and the near-infrared light wavelength to 830nm. The dual-wave alternating projection function is then adjusted, with a preset alternation frequency of 1-2 times / second to ensure smooth switching between the two light waves, stable intensity, and no light interruptions or overlaps. The user is guided to maintain a seated posture with eyes naturally looking straight ahead. The projection angle and distance of the phototherapy device are adjusted (maintaining a distance of 15-20cm from the eyes). Using the device's built-in positioning module, the ring-shaped light spot is precisely aligned with the ring-shaped area 1-3mm behind the corneal limbus of the ciliary muscle, ensuring complete coverage of the target area without deviation or missed areas. After positioning, the device position is locked to prevent displacement during projection. Afterwards, dual-wave alternating projection can be performed: turn on the projection switch, and the device will alternately project red light and near-infrared light onto the target area according to the preset frequency. The two light waves will cycle and switch to form a ring-shaped light spot. During the projection process, the power density of the light waves will be monitored in real time to ensure that the power of the two light waves is stably maintained at the preset value. At the same time, the smoothness of the alternation will be monitored to avoid frequency fluctuations or light interruption, so as to prevent affecting the phototherapy effect or irritating the eyes.

[0080] Step 502: Continue projection until the light wave projection duration reaches the specified adjustment duration, then terminate the photobiological adjustment process.

[0081] The phototherapy device has a built-in timing module that starts timing from the start of the dual-wave alternating projection, recording the total projection time (cumulative projection time, excluding switching intervals) in real time and comparing it with the preset adjustment time (5 minutes for relief mode, 3 minutes for prevention mode) to ensure accurate timing. When the timing module shows that the projection time has reached the preset adjustment time, the device automatically shuts down the dual-wave alternating projection function and stops projecting light waves to the eyes. If the user's eye discomfort is detected in real time during the projection process (such as abnormal blinking frequency or abnormal refractive drift), a manual termination command can be triggered to terminate the process in advance, and the reason for termination is recorded. After the process is terminated, the device automatically records the key parameters of this phototherapy (light power density, actual projection time, alternation frequency, and light spot positioning), and prompts the user to close their eyes and rest for 1-2 minutes to help the ciliary muscle relax and ensure maximum phototherapy effect. Subsequent phototherapy plans can be optimized based on the recorded parameters.

[0082] This application embodiment precisely sets the light wave power density and projects red light and near-infrared light alternately at a preset frequency to form a ring-shaped light spot that targets the corresponding area of ​​the ciliary muscle. Combined with a preset adjustment duration to control the total light energy intake, the two light waves can respectively play the role of improving ocular microcirculation and promoting ciliary muscle relaxation, while avoiding the problem of excessive energy caused by the superposition of the two waves. This achieves precise and gentle photobiological regulation of the ciliary muscle, which can effectively relieve accommodative spasm and ensure the safety of phototherapy.

[0083] Next, combined Figure 6 The process of implementing photobiological regulation of users based on a determined regulation frequency is described in detail.

[0084] Reference Figure 6 This illustrates a flowchart of another photobiological regulation method provided in an embodiment of this application. Figure 6 As shown, the photobiological regulation method may include steps 601 and 602.

[0085] Step 601: Determine the adjustment frequency corresponding to the user based on the adjustment mode.

[0086] In this embodiment, the adjustment frequency refers to the number of times photobiological regulation is performed daily or every other day, i.e., once a day, twice a day, or once every other day. It is determined by the adjustment mode and is a key parameter for controlling the phototherapy cycle and ensuring the adjustment effect.

[0087] During photobiological modulation, the user-adapted modulation mode (relief mode / prevention mode) determined earlier can be invoked. Simultaneously, the preset modulation frequency parameters corresponding to each of the two modes are retrieved from the system to ensure scientific accuracy and consistency in parameter matching. If the user is in relief mode (for severe accommodative spasm), the modulation frequency is set to twice daily to quickly relieve excessive ciliary muscle contraction and improve modulation efficiency. If the user is in prevention mode (for mild accommodative spasm or routine maintenance), the modulation frequency is set to once daily or once every other day to maintain normal ciliary muscle function while avoiding excessive light stimulation. The determined modulation frequency (once daily / twice daily / every other day) is fed back to the control module of the phototherapy device for coordinated matching with light power density and modulation duration parameters, providing a core basis for subsequent photobiological modulation operations.

[0088] Step 602: Using a dual-wave projection method, the user is subjected to photobiological regulation according to the adjustment frequency, the light power density, and the adjustment duration.

[0089] Calling the established core parameters (light power density, adjustment duration, and adjustment frequency), the red light wavelength is set to 660nm and the near-infrared light wavelength to 830nm. The dual-wave projection function is tested to ensure synchronous projection of both light waves with stable intensity and no light interruptions or overlap. The user is guided to maintain a seated posture with eyes naturally looking straight ahead. The projection angle and distance of the phototherapy device are adjusted (maintaining a distance of 15-20cm from the eyes). Using the device's built-in positioning module, the ring-shaped light spot is precisely aligned with the ring-shaped area 1-3mm behind the corneal limbus (corresponding to the ciliary muscle area), ensuring complete coverage of the target area without deviation or missed areas. The dual-wave synchronous projection operation is then performed: the projection switch is activated, and red and near-infrared light are projected synchronously, forming a ring-shaped light spot acting on the target area. During projection, the light power density is monitored in real time to ensure it remains stable within the preset range. Simultaneously, the determined adjustment frequency is followed (once daily / twice daily or every other day), with each projection strictly adhering to the preset adjustment duration. After a single projection reaches the preset adjustment duration, the projection automatically stops. The projection process is repeated daily or every other day according to the adjustment frequency until a full adjustment cycle is completed. If eye discomfort is detected during projection, the projection can be manually terminated, and subsequent projections will be adjusted according to the set frequency. After each projection, the device automatically records the operation parameters (adjustment frequency, power density, and actual projection duration) and prompts the user to take a break. Throughout the entire phototherapy cycle, the set adjustment frequency must be strictly followed to ensure continuous and appropriate adjustment of the ciliary muscle.

[0090] This application embodiment achieves precise and gentle adjustment of the ciliary muscle by specifying the adjustment frequency as an execution cycle of once a day, twice a day, or once every other day, combined with a dual-wave synchronous projection method, and matched with appropriate light power density and adjustment duration. This effectively relieves accommodative spasm caused by excessive ciliary muscle contraction, and avoids overstimulation through scientific adjustment frequency, ensuring the safety and specificity of phototherapy. At the same time, it avoids the drawbacks of blind phototherapy and helps improve visual comfort of the eyes.
