Description

Technical Field

[0001] This invention belongs to the field of optical modulation devices, and more specifically, relates to a training refractive modulation device and training method that can adapt to visual axis shift. Background Technology

[0002] Training refractive modulation devices are optical devices used for visual function training. By adjusting the refractive power of the lenses, they provide a suitable visual training environment for people with refractive errors or strabismus, helping to improve visual function and relieve eye fatigue. They are suitable for scenarios such as myopia control and strabismus assisted correction, and are important equipment in visual function rehabilitation training.

[0003] Existing training refractive modulation devices have their refractive power precision area concentrated in the central circle of the lens. The training effect is highly dependent on the alignment between the eye's visual axis and the central circle. However, the visual axis of strabismus users is prone to deviating from the central circle of the lens, making it impossible to effectively utilize the precision refractive power area. This not only directly affects the targeting and effectiveness of vision training, but may also increase eye strain due to visual deviation, making it difficult to meet the specific training needs of strabismus patients. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides an adaptive visual axis shift training refractive modulation device and training method, the purpose and effectiveness of which are achieved through the following specific technical means:

[0005] Its structure includes a protective shell, a protective cover, a charging port, training glasses, and a charging base. The protective cover is slidably fitted with the protective shell, the training glasses are placed inside the protective shell, and the charging port is connected to the charging base through the protective shell.

[0006] The training glasses include a nose pad, an adjustable lens, a microphone, a charging head, a control terminal, temples, an adjustment rod, and a power switch. The nose pad is connected to the control terminal housing via the adjustment rod. The top of the adjustable lens is installed inside the control terminal. The microphone, charging head, and control terminal housing are an integrated structure. The temples are hinged to the control terminal housing. The power switch is connected to the control terminal. The control and receiving system inside the control terminal is used to drive the adjustable lens.

[0007] As a further improvement of the present invention, the adjusting lens includes an inner lens, a limiting channel, a connecting block, an adjusting column, a micro motor, and an outer lens. The connecting block is locked in the groove of the limiting channel for limiting. The connecting block and the adjusting column are an integrated structure. The adjusting column is movably connected to the micro motor. There are four connecting blocks in total, and two are connected to the inner lens and the outer lens respectively. The groove structure of the limiting channel is adapted to the movement trajectory of the connecting block to ensure that the displacement always proceeds along the optical coupling adaptation direction.

[0008] As a further improvement of the present invention, the inner lens includes a connecting groove, a micro infrared group, and an inner curved lens. The micro infrared group is installed on the outer frame of the inner curved lens. The connecting groove is connected to the outer frame of the inner curved lens. The curved surface structure of the inner curved lens and the outer curved lens provides a basic optical carrier for refractive modulation.

[0009] The outer lens includes a mounting groove and an outer curved lens, and the mounting groove is connected to the outer frame of the outer curved lens.

[0010] As a further improvement of the present invention, the adjustment rod can be adjusted to support the angle as needed, the charging head is placed and connected to the charging base, the speaker plays an indicator tone, the control terminal is equipped with a control and receiving system, and the angle adjustment of the adjustment rod can be adapted to the facial contours of different users.

[0011] As a further improvement of the present invention, the micro motor is provided with four micro motors, two of which are grouped together and cooperate with four adjustment columns. The inner lens and the outer lens are parallel to each other. The inner and outer lenses are engraved with annular optical diffraction microgrooves that are invisible to the naked eye on their opposite inner surfaces. The inner and outer lenses can precisely control the light modulation effect by changing the overlap area.

[0012] As a further improvement of the present invention, the connecting groove, the mounting groove and the connecting block are connected. There are a total of six micro infrared groups, which are distributed on the left and right sides and the bottom. The outer curved lens can be adjusted to the required refractive power by moving it relative to the inner curved lens. The group distribution design of the micro infrared groups can capture the position of the eye's visual axis in 360°.

[0013] As a further improvement of the present invention, the miniature infrared assembly includes a mounting base and an infrared monitor. The infrared monitor is snapped onto the mounting base, and the mounting base is fixed to the outer frame of the inner curved lens. The mounting base fixes the infrared monitor to the outer frame of the inner curved lens, ensuring that the detection direction is always aligned with the visual axis area of ​​the eyeball.

[0014] As a further improvement of the present invention, the infrared monitor can be installed or removed as needed, the infrared monitor monitors and controls the line of sight, and the monitoring and control function of the infrared monitor is used for the alignment of the optical medium and the line of sight.

[0015] As a further improvement of the present invention, the training method of the adaptive visual axis shift training refractive modulation device is as follows:

[0016] S1: The user presses and holds the power button to activate the training glasses, establishes a stable wireless connection with the control terminal via Bluetooth on the mobile phone, inputs the precise refractive power parameters required for their own visual function training in the mobile APP and submits them. At the same time, the nose pad support angle can be adjusted by bending the adjustment rod according to the wearer's facial contours to ensure that the training glasses fit well and do not shift.

[0017] S2: After the internal receiving system of the control terminal accurately receives the diopter command transmitted by the mobile APP, the control system outputs a drive signal to the micro motor. The micro motor drives the adjustment column to move smoothly along the limit track through the connecting block, and the outer lens moves parallel to the inner lens. The overlapping area is adjusted by the annular optical diffraction microgroove on the inner and outer surfaces of the inner and outer lenses until the diopter is accurately matched and set. Then the micro motor stops working and the diopter remains fixed, providing users with a stable light modulation training environment.

[0018] S3: During training, the miniature infrared group installed on the outer frame of the inner curved lens captures the user's eye axis position data in real time through an infrared monitor, and continuously verifies the position correspondence with the annular optical diffraction microgroove of the inner lens. The verification data is synchronously transmitted to the internal receiving system of the control terminal.

[0019] S4: If the control terminal determines that the visual axis is not within the preset adaptation range after parsing the data, it immediately outputs a position calibration command to the micro motor. The micro motor drives the connecting block to move the inner lens along the limiting track for adjustment. The outer lens moves synchronously through the connecting block, always maintaining the relative positional relationship with the inner lens, ensuring that the fixed refractive power does not fluctuate, until the optical center of the inner lens is precisely aligned with the visual axis of the eyeball.

[0020] The displacement accuracy of the micro motor is 0.01 mm.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] Firstly, it possesses precise refractive modulation adaptation capabilities. By establishing a wireless connection between the mobile phone and the control system at the control terminal, users can accurately set the target refractive power parameters according to their own training needs. With the help of the annular optical diffraction microgrooves on the inner and outer surfaces of the inner and outer lenses to form a stable optical coupling, it can be precisely adjusted to the set refractive power and kept fixed, thus creating a bias-free light modulation environment for trainees and ensuring the accuracy and effectiveness of visual function training.

[0023] Secondly, it achieves adaptive calibration for visual axis shift. The six infrared monitors of the miniature infrared group are distributed in three groups on the outer frame of the inner curved lens. They can accurately capture the position of the wearer's eye axis in real time and verify the position correspondence with the annular optical diffraction microgroove of the inner lens. When visual axis shift is detected, the data is transmitted to the control terminal in real time. The control system quickly drives the connecting block to adjust the position of the inner lens until it is precisely aligned with the visual axis. At the same time, the outer lens is synchronously linked to maintain parallel fixed refractive power. This not only solves the problem of visual axis alignment for strabismus users, but also ensures the stability of the light modulation adaptation effect.

[0024] Thirdly, the adjustment rod has flexible bending adjustment characteristics, which can accurately adjust the support angle according to the facial contours and nose shapes of different users, so that the nose pad fits the wearer's nose closely, preventing refractive modulation deviation caused by wear displacement, ensuring the consistency of light modulation parameters during training, and improving the wearing comfort of different groups of people.

[0025] Fourth, for those with common refractive errors, precise refractive power can be set via mobile phone. By utilizing the parallel translation of the inner and outer lenses and the optical coupling effect of the annular optical diffraction microgroove, a clear visual environment without deviation can be constructed. This trains the visual system to adapt to and consolidate the precise refractive state, relieves compensatory fatigue of the ciliary muscle, and reduces the risk of myopia progression. For strabismus users, through the visual axis monitoring and lens position calibration of the miniature infrared group, the optical center of the inner lens is precisely aligned with the visual axis while maintaining a fixed refractive power. This trains the binocular visual axis alignment ability and binocular single vision function, corrects visual habit deviations caused by strabismus, and reduces double vision and diplopia problems.

[0039] The present invention provides a training refractive modulation device and training method that can adapt to visual axis deviation. Its structure includes a protective shell 1, a protective cover 2, a charging port 3, training glasses 4, and a charging base 5. The protective cover 2 is slidably engaged with the protective shell 1, the training glasses 4 are placed inside the protective shell 1, and the charging port 3 is connected to the charging base 5 through the protective shell 1.

[0040] The training glasses 4 include a nose pad 41, an adjustable lens 42, a microphone 43, a charging head 44, a control terminal 45, temples 46, an adjustment rod 47, and a power switch 48.

The adjustable lens 42 is precisely driven and fixed by the data from the control terminal 45 to ensure the stability and accuracy of the refractive power.

[0041] The adjustable lens 42 includes an inner lens 21, a limiting channel 22, a connecting block 23, an adjusting column 24, a micro motor 25, and an outer lens 26. The connecting block 23 is locked in the groove of the limiting channel 22 for limiting. The connecting block 23 and the adjusting column 24 are integrated. The adjusting column 24 is movably connected to the micro motor 25. There are four connecting blocks 23 in total, and two are connected to the inner lens 21 and the outer lens 26 respectively. The groove structure of the limiting channel 22 is adapted to the movement trajectory of the connecting block 23 to ensure that the displacement always proceeds along the optical coupling adaptation direction. The micro motor 25 transmits drive through the adjusting column 24 to achieve synchronization of displacement and optical parameter adjustment.

[0042] The inner lens 21 includes a connecting groove 11, a miniature infrared group 12, and an inner curved lens 13. The miniature infrared group 12 is installed on the outer frame of the inner curved lens 13. The connecting groove 11 is connected to the outer frame of the inner curved lens 13. The curved surface structure of the inner curved lens 13 and the outer curved lens 15 provides a basic optical carrier for refractive modulation. The miniature infrared group 12 monitors and calibrates the relative position of the inner curved lens 13 and the visual axis of the eyeball.

[0043] The outer lens 26 includes a mounting groove 14 and an outer curved lens 15, wherein the mounting groove 14 is connected to the outer frame of the outer curved lens 15.

[0044] The adjustable rod 47 can be adjusted to support the angle as needed. The charging head 44 is placed and connected to the charging base 5. The speaker 43 plays an indicator tone.

[0045] The micro motors 25 are provided in groups of four, with two motors forming a group, and cooperate with four adjustment columns 24. The inner lens 21 and the outer lens 26 are parallel to each other. The inner and outer surfaces of the inner lens 21 and the outer lens 26 are engraved with annular optical diffraction microgrooves that are invisible to the naked eye. The inner lens 21 and the outer lens 26 can precisely control the light modulation effect by changing the overlap area. The four groups of micro motors 25 cooperate to drive and ensure that the inner lens 21 and the outer lens 26 are in a stable parallel state.

[0046] The connecting groove 11, the mounting groove 14 and the connecting block 23 are connected. There are six miniature infrared groups 12, which are distributed on the left and right sides and the bottom in groups of three.

The cooperation structure of the connecting groove 11, the mounting groove 14 and the connecting block 23 ensures that the optical adaptation relationship is always maintained during translation.

[0047] The specific usage and function of this embodiment are as follows:

[0048] In this invention, when the training glasses 4 are not in use, they can be stored and protected inside the protective case 1 to prevent the lenses from getting dusty or being damaged by external forces. When charging, a circuit connection is established between the charging port 3 on the protective case 1 and the charging base 5, and then the charging base 5 connects to the charging head 44 of the training glasses 4 to achieve stable power supply. The user activates the device by pressing and holding the power button 48, and the mobile phone connects to the device via Bluetooth. After connection, the user inputs the required refractive power parameters and sends adjustment commands through the mobile phone APP. After the internal receiving system of the control terminal 45 of the training glasses 4 accurately receives the command, the control system outputs a drive signal to the micro motor 25, and the micro motor 25 drives the connection. Block 23 moves smoothly along the limiting channel 22. The connecting block 23 is linked to the outer curved lens 15 through the mounting slot 14, so that the outer curved lens 15 moves parallel to the inner curved lens 13 until it is adjusted to the set diopter value. Then the micro motor 25 stops working and the diopter remains fixed, ensuring that the refractive state of the adjusting lens 42 is stable and adaptable to the user's training needs. If the wearer is a young child, the support angle can be adjusted by bending the adjusting rod 47 so that the nose pad 41 fits closely to the child's nose contour, improving the comfort and stability of wearing, and preventing the glasses from shifting during training and affecting the use effect. This focuses on the fixed diopter training of ordinary refractive errors.

[0049] Example 2: As shown in the attached document Figure 9 To be continued Figure 10 As shown:

[0050] The miniature infrared unit 12 includes a mounting base 31 and an infrared monitor 32. The infrared monitor 32 is snapped onto the mounting base 31, which is fixed to the outer frame of the inner curved lens 13. The mounting base 31 fixes the infrared monitor 32 to the outer frame of the inner curved lens 13, ensuring that the detection direction is always aligned with the visual axis area of ​​the eyeball. The snap-fit ​​connection design of the mounting base 31 facilitates the installation, removal, and maintenance of the infrared monitor 32.

[0051] The infrared monitor 32 can be installed and removed as needed. The infrared monitor 32 monitors and controls the line of sight. The monitoring and control function of the infrared monitor 32 is used for the alignment of the optical medium and the line of sight. The detachable design of the infrared monitor 32 can be adapted to the detection needs of different line of sight offset scenarios.

[0052] The training method for the adaptive visual axis shift training refractive modulation device is as follows:

[0053] S1: The user presses and holds the power button 48 to activate the training glasses 4, establishes a stable wireless connection with the control terminal 45 via Bluetooth on the mobile phone, inputs the precise refractive power parameters required for their own visual function training in the mobile APP and submits them. At the same time, the user can bend the adjustment rod 47 to adjust the support angle of the nose pad 41 according to the wearer's facial contours to ensure that the training glasses 4 fits well and does not shift.

[0054] S2: After the internal receiving system of the control terminal 45 accurately receives the diopter command transmitted by the mobile APP, the control system outputs a drive signal to the micro motor 25. The micro motor 25 drives the adjustment column 24 to move smoothly along the limit track 22 through the connecting block 23. The outer lens 26 moves parallel to the inner lens 21. The overlapping area is adjusted by the annular optical diffraction microgroove on the inner side of the inner lens 21 and the outer lens 26 until the diopter is accurately matched and set. The micro motor 25 stops working and the diopter remains fixed, providing users with a stable light modulation training environment.

[0055] S3: During training, the miniature infrared group 12 installed on the outer frame of the inner curved lens 13 captures the position data of the user's eye axis in real time through the infrared monitor 32, and continuously performs position correspondence verification with the annular optical diffraction microgroove of the inner lens 21. The verification data is synchronously transmitted to the internal receiving system of the control terminal 45.

[0056] S4: If the control terminal 45 determines that the visual axis is not within the preset adaptation range after parsing the data, it immediately outputs a position calibration command to the micro motor 25. The micro motor 25 drives the connecting block 23 to move the inner lens 21 along the limiting channel 22 for adjustment. The outer lens 26 moves synchronously with the connecting block 23, always maintaining the relative positional relationship with the inner lens 21, ensuring that the fixed refractive power does not fluctuate, until the optical center of the inner lens 21 is precisely aligned with the visual axis of the eyeball.

[0057] The displacement accuracy of the micro motor 25 is 0.01mm, and the limiting channel 22 limits the connection block 23.

[0058] The specific usage and function of this embodiment are as follows:

[0059] In this invention, when the wearer has strabismus, the infrared monitor 32 installed on the outer frame of the inner curved lens 13 accurately monitors the position of the wearer's visual axis in real time and forms a positional correspondence verification with the annular optical diffraction microgroove on the inner side of the inner lens 21. If the visual axis is not detected to be within the preset adaptation range, the infrared monitor 32 transmits the collected visual axis offset data to the receiving and control system in the control terminal 45 in real time. After the system quickly analyzes the data, it generates a position calibration command and drives the connecting block 23 to move the inner lens 21 along the limiting channel 22 to make translational adjustment until the optical center of the inner lens 21 is accurately aligned with the visual axis of the eye. During this calibration process, the outer lens 26 moves synchronously with the inner lens 21 through the linkage of the connecting block 23, always maintaining the relative positional relationship with the inner lens 21, ensuring that the previously adjusted refractive power value is stable and without fluctuation, achieving a dual adaptation of accurate visual axis alignment and fixed refractive power, meeting the training and use needs of strabismus wearers.
