Description

Technical Field

[0001] This utility model relates to a visual training system for achieving closed-loop training, belonging to the category of eye exercise equipment. Background Technology

[0002] A reversible paddle, also known as a flip paddle or butterfly paddle, consists of two pairs of lenses of equal power, one positive and one negative. Reversible paddles are generally used to alter the eye's accommodative stimulation. The positive lens reduces accommodative stimulation, while the negative lens increases it, and the convergence stimulation remains unchanged. Therefore, the change in accommodative convergence is accompanied by an equal but opposite change in fusional convergence / divergence. In traditional reversible paddle training, a card is placed at a fixed position in front of the paddle. The eye identifies the image of the card formed by the lens through the paddle. By switching lenses of different powers, the eye identifies images located in different positions, thus achieving the training objective. During reversible paddle training, the two pairs of lenses need to be constantly switched back and forth.

[0003] Existing reversal frames rely on manual or mechanical methods to control the switching of multiple lenses with different prescriptions. Manual methods increase the burden on the user and are difficult to maintain, while mechanical methods are noisy and require adjustment time. Furthermore, this lens-switching method requires the eye to constantly adapt to different lenses to maintain alignment between the visual axis and the lens center, making it difficult to guarantee a truly effective training duration and thus affecting the training effect.

[0004] Furthermore, existing reverse-image systems lack a feedback mechanism, failing to monitor and record whether the human eye can effectively identify images from different positions, thus hindering the achievement of a closed-loop training system. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a visual training system.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0008] An electronic reversal camera includes a first display optical path, a second display optical path, a display screen, a control module, a first storage module, and a first signal transmission module. The first and second display optical paths correspond to different display areas of the display screen, and the control module controls the display areas and display content of the display screen, so that the display areas corresponding to different display optical paths alternately display different display content, and virtual images of different display content are formed alternately on the far focal plane and near focal plane through the first and second display optical paths, respectively.

[0009] The feedback device is wired or wirelessly connected to the control module via the first signal transmission module.

[0019] Alternatively, preferably, the feedback device or the control terminal further includes a setting module, which is at least connected to the control module; the setting module is configured to set the user-related information, training parameters, and display parameters.

[0020] The visual training system provided by this invention includes an electronic reversal camera and a feedback device. The electronic reversal camera controls two display areas corresponding to different display optical paths to alternately display different content at different virtual image positions in front of the user's eyes through the first and second display optical paths. The user, through the feedback device, performs different feedback operations for different display content. The feedback device generates corresponding feedback signals based on these operations and sends these signals to the electronic reversal camera, thus achieving closed-loop training. This visual training system can record the user's actual feedback during the eye training process, thereby recording the accuracy of the content recognized by the human eye and effectively determining whether the human eye can see clearly during training. This ensures the effectiveness and traceability of the electronic reversal camera training. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0034] like Figure 1 As shown, the visual training system provided by this utility model includes: an electronic reverse imager 1, a feedback device 2, and a control terminal 3, which can realize closed-loop training of human vision.

[0035] The electronic reversal image 1 is used to alternately display virtual images of different content located on the far and near focal planes to the human eye through a dual-light-path electronic display system. When the human eye views the virtual images located on the far and near focal planes displayed by the electronic reversal image 1, the ciliary muscle needs to adjust to different states, thereby training the ciliary muscle of the human eye.

[0036] To ensure the effectiveness of training, the training results need to be monitored. This visual training system provides a feedback device 2, which sends feedback signals to the electronic reversal frame 1. The user performs different feedback operations to the feedback device 2 in real time based on the displayed content. The feedback device 2 generates feedback signals based on these operations and sends the corresponding signals to the electronic reversal frame 1. Then, the control module in the electronic reversal frame 1 judges the correctness of the feedback signals based on the displayed content and the received feedback signals, thereby forming training results and achieving closed-loop training. These training results can be temporarily or permanently stored in the electronic reversal frame 1.

[0037] The visual training system may also include an independently configured control terminal 3. This control terminal serves two purposes: firstly, it sets relevant parameters for the electronic reversal camera, including user-related information, training parameters, and display parameters for the electronic reversal camera. The user-related information includes at least user identity information, interpupillary distance, and refractive power representing the intensity of accommodation training. The training parameters include at least the training mode and training duration settings. The display parameters include at least the display area and display content. Secondly, it stores the training results of the human eye. These results can be stored long-term in the control terminal 3, forming a training archive, thereby enabling long-term monitoring of the human eye training. The configuration of this control terminal 3 is not mandatory; its presence or absence does not affect the implementation of the aforementioned closed-loop training.

[0038] Specifically, such as Figures 2 to 6 As shown, the electronic reversal racket 1 includes a reversal racket body 11 and a headband 12, wherein the adjustable-length headband 12 is disposed on the upper part of the reversal racket body 11. Two dual-light-path electronic display systems (left dual-light-path electronic display system 13 and right dual-light-path electronic display system 14) are disposed within the outer casing of the reversal racket body 11, corresponding to the left-eye display and right-eye display, respectively.

[0039] The left dual-beam electronic display system 13 corresponding to the left eye and the right dual-beam electronic display system 14 corresponding to the right eye respectively use, as follows: Figure 4 The optical path principle is shown. Each dual-optical-path electronic display system includes a first display optical path, a second display optical path, a display screen, and a control module. Two dual-optical-path electronic display systems share the same display screen 4 and the same control module. See also... Figure 4 and Figure 5In each dual-light-path electronic display system, the first display light path and the second display light path correspond to different display areas (first area 210 and second area 220) of the display screen 4, respectively. The control module controls the display area and display content of the display screen 4 to make the display areas 210 and 220 corresponding to different display light paths alternately display different display content (e.g., display targets with different opening directions), and form virtual images of different display content on the far focal plane and near focal plane alternately through the first display light path and the second display light path, respectively.

[0040] like Figure 4 As shown, the first display optical path and the second display optical path share a polarizing beam splitter 103 and a positive lens 106. The light rays from the two display optical paths are directed to the polarizing beam splitter 103 from different directions. After being combined by the polarizing beam splitter 103 and magnified by the positive lens 106, the light rays are directed to the same exit pupil position. The exit pupil positions of the first display optical path and the second display optical path are the same, and the exit pupil centers of the first display optical path and the second display optical path coincide, corresponding to the visual axis of the human eye.

[0041] The light emitted from the image sources in the two display optical paths is reflected by different mirrors and then directed towards the polarizing beam splitter 103 from two opposite directions. The first light ray from the first display optical path is reflected by the polarizing beam splitter 103 and then directed towards the positive lens 106. The second light ray from the second display optical path is reflected by the polarizing beam splitter 103 and then directed towards another mirror 104 and then reflected back to the polarizing beam splitter 103. At the same time, the polarization state of the second light ray changes, and then it is transmitted through the polarizing beam splitter 103 and the positive lens 106, and together with the first light ray, it is directed towards the same exit pupil position 110 to form an image.

[0042] The first display optical path includes a first image source 107, a first reflecting mirror 101, a second reflecting mirror 102, a polarizing beam splitter 103, and a positive lens 106. A polarizing beam splitter film (PBS film) is attached to one side surface of the polarizing beam splitter 103. The function of the polarizing beam splitter film is to reflect first linearly polarized light and transmit second linearly polarized light. The polarization directions of the first and second linearly polarized light are perpendicular. The following description uses P-type light as the first linearly polarized light and S-type light as the second linearly polarized light as an example. The first image source 107 provides the first linearly polarized light (P-type linearly polarized light). After being reflected sequentially by the first reflecting mirror 101 and the second reflecting mirror 102, the first linearly polarized light is deflected by 90° and directed from the first direction towards the polarizing beam splitter 103. After being reflected by the polarizing beam splitter film, it passes through the positive lens 106 and is directed towards the exit pupil.

[0043] The second display optical path includes a second image source 108, a third reflector 105, a polarizing beam splitter 103, a fourth reflector 104, and a positive lens 106. A phase retardation film (QWP film, with the QWP film and PBS film at a 45° angle) is attached to one side surface of the polarizing beam splitter 103. The second image source 108 provides the first circularly polarized light (left-handed circularly polarized light). After being reflected by the third mirror 105, the first circularly polarized light is deflected by 90° and directed towards the polarizing beam splitter 103 from a second direction, which is opposite to the first direction. After passing through the phase retarder, the first circularly polarized light becomes first linearly polarized light (P-light). After being reflected by the polarizing beam splitter, it passes through the phase retarder again and becomes first circularly polarized light (left-handed circularly polarized light) which is directed towards the fourth mirror 104. After being reflected by the fourth mirror 104, it becomes second circularly polarized light and is directed towards the polarizing beam splitter 103. After being transmitted through the phase retarder, it becomes second linearly polarized light (S-light) and is transmitted through the polarizing beam splitter and the positive lens 106, directed towards the exit pupil position 110, which is the same as the first display light path.

[0044] In this dual-path electronic display system, the principal optical axis of the positive lens 106 is set to correspond to the viewing axis, and the polarizing beam splitter 103 is set on the side of the positive lens 106 away from the human eye and at a 45° angle to the viewing axis; the third reflecting mirror 105 and the second reflecting mirror 102 are respectively set on both sides of the polarizing beam splitter 103, for example, on the top and bottom sides or the left and right sides; wherein, in the first display optical path, a first reflecting mirror 101 is also provided to reflect the first light emitted by the first image source 107 onto the surface of the second reflecting mirror 102, thereby increasing the optical path of the first display optical path, and the sum of the angle between the first reflecting mirror 101 and the optical axis and the angle between the second reflecting mirror 102 and the optical axis is equal to 45°; in the second display optical path, a fourth reflecting mirror 104 is provided on the side of the polarizing beam splitter 103 away from the human eye, for performing polarization state conversion on the second light reflected by the polarizing beam splitter and increasing the optical path of the second display optical path. In this embodiment, the first reflector 101 and the image source 107 are located on both sides of the second reflector 102, the second reflector 102 and the third reflector 105 are tilted in the same direction, and the included angle between the second reflector 102 and the third reflector 105 is equal to the tilt angle of the first reflector 101 relative to the optical axis.

[0045] In this embodiment, the first image source 107 and the second image source 108 can be implemented using the same display screen 4, for example, using an LCD screen that emits P-type polarized light. The first image source 107 is the first area 210 of the display screen 4, used to provide first linearly polarized light, P-light; the second image source 108 is the second area 220 of the display screen 4, and a phase delay sheet is provided on the light-emitting surface of the second area 220 to convert the first linearly polarized light (P-light) into first circularly polarized light (left-handed circularly polarized light).

[0046] The first image source 107 and the second image source 108 can also be implemented using the same display screen 4 that emits natural light, such as an OLED or Micro OLED display screen. By attaching different polarization composite films to different areas of the light-emitting surface of the screen, image sources with different polarization properties can be provided. Preferably, the area of ​​the first image source 107 and the second image source 108 that is illuminated at one time is not less than 2mm*5mm.

[0047] Figure 5 A schematic diagram shows an image source for two dual-optical-path electronic display systems using the same display screen 4, where the left and right sides of the display screen 4 correspond to the left-eye display and the right-eye display, respectively. The first region 210 and the second region 220 of the display screen are located above and below the horizontal line in the middle of the display screen, respectively, and are vertically staggered. The second region 220, located below and used for near vision, is closer to the nose than the first region 210, which is located above and used for distance vision. In this embodiment, the second region 220 corresponding to the second display optical path is closer to the center of the display screen 4, thus the image display corresponds to the increased angle between the visual axes of the two eyes when viewing an image at close range.

[0048] In this dual-light-path electronic display system, the first and second display light paths have different optical paths, different focal plane positions (a far focal plane away from the human eye and a near focal plane closer to the human eye, respectively), and different virtual image distances. The virtual images formed by the first and second display light paths correspond to the images formed on a fixed object by lenses of different powers placed in front of the human eye. Specifically, the virtual image formed on the far focal plane corresponds to the image formed on a fixed object by a lens of positive power placed in front of the human eye, corresponding to the relaxation of human eye accommodation. The virtual image formed on the near focal plane corresponds to the image formed on a fixed object by a lens of negative power placed in front of the human eye, corresponding to the tension of human eye accommodation. Thus, the control module controls the alternating display of the first and second display light paths by controlling the alternating display of the first and second image sources 107 and 108, thereby achieving alternating training of near and far vision and training of tension and relaxation of the ciliary muscle of the human eye.

[0049] This electronic reversal camera 1, through a dual-light-path system and an electronic screen, achieves different virtual image distances. The image formed by the two display light paths is identical to the image formed by placing a mechanical reversal camera and a card in front of the viewer's eyes and switching between different diopter lenses on the reversal camera. By controlling the alternating display of the two display light paths, a similar effect to eye training using a reversal camera can be achieved. Furthermore, this invention achieves different virtual image distances through a dual-light-path system and an electronic screen; the switching between the two display light paths is controlled electronically, eliminating the need for mechanical structures to achieve the switching display of different virtual image distances.

[0050] In addition, such as Figure 2 and Figure 3 As shown, the electronic reversal camera 1 also includes a diopter adjustment mechanism 16 and an interpupillary distance adjustment mechanism 17. The diopter adjustment mechanism 16 adjusts the position of the reflectors in the first and / or second display light paths, thereby adjusting the difference in refractive power between the two light paths of the dual-light-path electronic display system and thus adjusting the training intensity for the human eye. The interpupillary distance adjustment mechanism 17 adjusts the distance between the left dual-light-path electronic display system 13 and the right dual-light-path electronic display system 14 to accommodate different interpupillary distances.

[0051] To adjust the training intensity of the ciliary muscle of the human eye through the two display optical paths, the virtual image distance of both optical paths can be adjusted simultaneously, or only the virtual image distance of a single display optical path can be adjusted. The optical path difference between the first and second display optical paths can be adjusted by moving one or more mirrors located on opposite sides of the polarizing beam splitter 103. For example, by moving the second mirror 102 and the third mirror 105 in the same direction (e.g., simultaneously moving towards...). Figure 5 By moving the first mirror 101 upwards (while simultaneously controlling the illuminated area of ​​the display screen), the optical path difference between the two display optical paths can be adjusted. To meet the imaging requirements before and after the second mirror 102 moves, the length of the first mirror 101 should ensure that the first light rays reflected by the first mirror 101 before and after the second mirror 102 moves can illuminate the surface of the second mirror 102. This adjustment method can change the virtual image distance of the two display optical paths. Moreover, the small movement of the mirror in a single optical path allows for a simultaneous increase in the intensity of bidirectional eye training, thereby increasing the intensity of ciliary muscle training.

[0052] In the illustrated embodiment, the electronic reversal camera 1 has a manually adjustable diopter adjustment mechanism 16 for adjusting the position of one or more mirrors in the first and second display optical paths, thereby adjusting the difference in diopter between the two display optical paths. Alternatively, the diopter adjustment mechanism 16 can be electrically adjusted using a motor and corresponding transmission components. Furthermore, the diopter adjustment mechanism 16 can be connected to a control module to achieve automatic adjustment of the lens position.

[0053] In the automatically adjusted electronic reversal image 1, on the one hand, the control module 5 adjusts the position of the mirrors used in the two display optical paths according to user-related information (e.g., human eye adjustment training diopter) to change the difference in diopter between the two display optical paths; on the other hand, the control module 5 generates corresponding display parameters (e.g., the position and size of the display area) according to the aforementioned user-related information, and changes the display area and display content on the display screen according to the display parameters, so that the size of the virtual image formed by the two display optical paths corresponds to the human eye resolution when observing the virtual image located at the far focal plane and near focal plane.

[0054] During eye training, by controlling the display of two dual-beam electronic display systems, it is possible to display only the left eye, only the right eye, or both eyes simultaneously. The dual-beam electronic display system 13 corresponding to the left eye and the dual-beam electronic display system 14 corresponding to the right eye provide image sources through different areas of the same display screen 4. According to the display order of different optical paths in the two dual-beam electronic display systems, different display areas of the display screen are lit sequentially to achieve joint display of the two dual-beam electronic display systems.

[0055] like Figure 6 As shown, the electronic reversal camera 1 also includes a first storage module connected to the control module. This first storage module stores the training program, user-related information, and training results. The user-related information includes at least: user identity information, interpupillary distance, and refractive power representing the intensity of the accommodative training. Based on the user-related information stored in the first storage module, the control module changes the display area and content of the display screen, thereby achieving alternating display of different content at two focal plane positions through the dual-optical-path electronic display system. To achieve effective training of the human eye and monitoring of training results, not only are the contents displayed at the two focal plane positions different, but the multiple virtual images displayed sequentially on the same focal plane are also not entirely identical. Thus, the control module can judge the correctness of the feedback signal by comparing the displayed content and the feedback signal in real time, generating training results. These training results can be temporarily or permanently stored in the first storage module.

[0056] The electronic reversal camera 1 also includes a first signal transmission module. The feedback device 2 and the terminal device 3 are connected to the control module via the first signal transmission module, either wired or wirelessly. The wireless connection method includes any of the following: Bluetooth, infrared, Wi-Fi, NFC, ZigBee, etc.

[0057] like Figure 7 and Figure 8As shown, the feedback device 2 includes a signal input module and a signal transmission module. The signal transmission module can be wired or wirelessly connected to the control module through a first signal transmission module. The signal input module receives different feedback operations and generates corresponding feedback signals. The signal transmission module sends the feedback signals to the electronic reversal frame 1. The electronic reversal frame 1 receives the feedback signals through the first signal transmission module and transmits them to the control module. The control module combines the displayed content and the received feedback signals to determine the correctness of the feedback signals and form a training result.

[0058] Feedback device 2 includes a signal input module capable of receiving feedback operations from at least four directions, which correspond to the opening directions of the optotypes used in vision testing. Thus, the user can input signals corresponding to the optotype opening directions via the signal input module. The signal input module can be activated via buttons or a joystick.

[0059] The aforementioned feedback device 2 can be implemented using an external device that is wired to the electronic reversal frame (e.g., an external keyboard with up, down, left, and right buttons), or it can be implemented using any form of remote control device (see [link]). Figure 8 (The remote control shown).

[0060] like Figure 8 The feedback device 2 shown is a remote control, including a housing 21, a joystick 22 (or a button) and a wireless signal transmitting area 23. The wireless signal transmitting area 23 is located at the front of the housing 21. Inside the housing 21, there is an electronic circuit system and a power supply module connected to the joystick 22 or the button. The electronic circuit system includes a signal transmitting module. The feedback signal emitted by the signal transmitting module can be emitted through the wireless signal transmitting area 23 at the front of the remote control and finally sent to the control module through the first signal transmission module.

[0061] In addition, the visual training system may also include an independently configured control terminal 3. The control terminal 3 can be a mobile terminal such as a mobile phone or tablet, or a desktop device such as a computer or host computer. Furthermore, the control terminal 3 can be not only a local device, but also a remote device that communicates with the electronic reversal camera 1 via the Internet.

[0062] like Figure 9As shown, the control terminal 3 includes a second signal transmission module, a second storage module, and a setting module. The control terminal 3 interacts with the electronic reversal camera 1 via the second signal transmission module and the first signal transmission module, and can be connected via wired or wireless connection. The second storage module stores user-related information and training results. By storing the training results long-term in the control terminal 3, long-term monitoring of the user's eye training results can be achieved, which is beneficial for doctors to adjust the training plan for the user in a timely manner. The setting module, through a human-computer interaction interface, allows for the setting of user-related information, training parameters, and display parameters.

[0063] As mentioned above, the control terminal 3 is not a mandatory component, and its absence does not affect the closed-loop training of the eyes. Moreover, in addition to being set up independently, the control terminal 3 can also be integrated with the feedback device to achieve signal feedback, training result storage, and parameter setting functions through the same device.

[0064] Furthermore, the setting and storage functions implemented by the control terminal 3 can also be achieved through the setting module and the first storage module integrated into the electronic reversal frame, without the need for a separate control terminal. For example... Figure 10 In another embodiment shown, the electronic reversal camera 1 includes a display screen 4, a control module, a first signal transmission module, a first storage module, and a setting module, wherein the setting module is at least connected to the control module; wherein, in this embodiment, the display screen 4, the control module, and the first signal transmission module are configured to... Figure 6 The embodiments shown are basically the same; the difference is that the first storage module of the electronic reversal camera 1 is also used for long-term storage of training results, and the electronic reversal camera 1 also includes a setting module, which is used to set user-related information, training parameters, and display parameters. It can be understood that the setting module can be configured in any one or more of the electronic reversal camera 1, feedback device 2, and control terminal 3, and can realize the above-mentioned setting of user-related information, training parameters, and display parameters without affecting the use of the vision training system.

[0065] In summary, the visual training system provided by this invention includes an electronic reversal camera and a feedback device. The electronic reversal camera controls two display areas corresponding to different display optical paths to alternately display different content at different virtual image positions in front of the user's eyes. The user, through the feedback device, performs different feedback operations on different display content. The feedback device generates corresponding feedback signals based on these operations and sends the corresponding feedback signals to the electronic reversal camera, thus achieving closed-loop training. This visual training system can record the user's actual feedback during the eye training process, thereby judging and recording the correctness of the content recognized by the human eye. It can effectively determine whether the human eye can see clearly during training, ensuring the effectiveness and traceability of the electronic reversal camera training.

[0066] The visual training system provided by this utility model has been described in detail above. Any obvious modifications made to this utility model by those skilled in the art without departing from its essential content will constitute an infringement of the patent rights of this utility model and will incur corresponding legal liability.
