Description

Technical Field

[0001] The present invention belongs to the technical field of vision care, and particularly relates to a system for assisting in training and improving unaided vision. Background Art

[0002] Vision care refers to the sum of health care measures for preventing the occurrence of eye diseases that hinder the development of visual function and damage visual function, treating non-organic eye diseases, organic eye diseases in the recovery period, and adverse eye symptoms that affect visual function, and promoting the normal development and recovery of visual function. Among them, vision training methods that use non-corrective and non-treatment means have gradually become the main means of vision training in various vision optimization centers at present because they do not affect patients and have low costs.

[0003] Vision training, also known as vision restoration training, aims to improve unaided vision and the overall level of vision health. Children and adolescents are in the growth and development period and the peak period of eye use. Helping people with vision problems establish good eye use habits, conducting scientific physical exercises and training on the eyes and visual system, and enhancing the eye accommodation ability are helpful for preventing and controlling myopia, repairing amblyopia, improving the level of unaided vision health, and reducing the dependence on vision correction means such as glasses and surgery.

[0004] Existing vision training mostly adopts an eye focusing and attention training method in combination with physical objects. Since the training methods are relatively flexible, there is no special auxiliary device for teaching. Instead, the trainer prepares items according to needs. This method makes each training process unable to be repeated, and the training effect is also unstable. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a system for assisting in training and improving unaided vision. By providing a fixed display interface and movable components, it assists the trainer to guide the trainee to continuously focus and change the viewing angle, making the vision training process more standardized and normalized compared with the existing ones.

[0006] The technical solution adopted by the present invention is as follows:

[0007] In a first aspect, a system for assisting in training and improving unaided vision according to the present invention provides a moving indication mark in a display interface to guide the line of sight of an object to continuously focus and recover. There are movable indication marks and fixed targets on the display interface;

[0008] Wherein the indication mark moves in a directional cycle in the display interface and has an indication end;

[0009] The targets are arranged on the directional cycle route of the indication mark, and the distance between the targets is an integer multiple of the single displacement length of the end of the indication end.

[0010] First of all, it should be noted that the vision training method is to change the focusing object by giving different target objects to the trainees, and conduct training for a certain period of time with high concentration, so as to adjust the eyeball through the continuous movement of the eye muscles. Since the main cause of myopia is that the curvature of the cornea or lens is too large, or the combination of each refractive component is abnormal, resulting in the refractive power exceeding the normal range, while the axial length of the eye is basically within the normal range. This continuous training can effectively adjust the eyeball, thus achieving the effect of adjusting vision.

[0011] During the training, since it is necessary to focus on a specific object, changing the target object for tracking focus in a state of high concentration is the core point of this training method. However, since the concentration and the eye focusing position are the subjective feelings of the trainees and cannot be confirmed through external observation, during the training, other devices need to be used to help the trainer obtain the real state of each trainee. Therefore, the system in the present invention can assist the trainer in training, and at the same time, effective feedback information can be obtained by setting appropriate rules, which is convenient for carrying out subsequent training.

[0012] The display interface therein refers to a spatial area, which is generally a plane, and multiple target objects are arranged in this spatial area. These target objects have different forms, including different shapes and colors. The target object can also be an actual item or a display object used to represent an actual item, but there needs to be a certain difference between adjacent or multiple groups of target objects to facilitate the trainees to distinguish.

[0013] The indication mark therein is a movable part pointing to any target object, including various ways such as its own movement and the movement of its indication end, and has a regular periodic reciprocating movement, which is convenient for training to master the time and can also control the line of sight within a certain area. The indication end is used to point to the target object, and after the same number of movement times at intervals, it will point to the next adjacent target object.

[0014] Before the training, the display interface is fixed, and the trainees arrange their specific positions according to their actual degree conditions, so that they are at an appropriate distance from the display interface for training. After the training starts, the indication mark will continue to move, and its indication end will move unidirectionally between each target object. The trainer will issue instructions at each time node, indicating that the trainee should immediately focus on a certain target object, and this target object is still at the position where the indication end is about to reach. At this time, the trainee needs to quickly find the corresponding target object and keep staring. When the indication end exactly points to this target object, raise the hand to indicate, thus completing one training.

[0015] Combined with the first aspect, the present invention provides the first implementation manner of the first aspect. The display interface is a fixed plane, and both the indication mark and the target object are convex structures arranged on this fixed plane.

[0016] Combined with the first implementation manner of the first aspect, the present invention provides a second implementation manner of the first aspect. The indicating identifier is a pointer rotatably connected to a fixed plane. A stepping motor is provided on the back surface of the fixed plane, and the output shaft of the stepping motor passes through the fixed plane and is connected to the pointer.

[0017] This fixed structure has a physical target, which is convenient for better focusing during training and has a good edge recognition effect. In the state of myopia where it is impossible to see clearly, its boundary can be determined, and gradually see the target clearly during continuous intensive training, so as to achieve the effect of improving eyesight.

[0018] Combined with the first implementation manner of the first aspect, the present invention provides a third implementation manner of the first aspect. The fixed plane is a fixing plate, and a mounting bracket is provided on the back surface of the fixing plate.

[0019] It is worth noting that generally during training, it is selected to be carried out indoors. Then, in a closed space, the fixing plate can be fixed on the wall surface. However, since the method of fixing on the wall surface will cause the distance between the training participants and the fixing plate in this space to gradually increase, in order to provide better space utilization, the fixing plate is set as a mounting structure and supported by a movable bracket. In the same room, two fixing plates with brackets are arranged back to back and cover different groups of training participants on both sides. By adjusting the movement positions of the indicating identifiers to be unified, the same trainer can issue instructions to two or more groups of training participants in different directions.

[0020] Combined with the first to third implementation manners of the first aspect, the present invention provides a fourth implementation manner of the first aspect. The target includes display pieces of various different shapes, and the display pieces are mounted on the fixed plane.

[0021] Combined with the first to third implementation manners of the first aspect, the present invention provides a fifth implementation manner of the first aspect. The target has a display surface, and decorative plates with different patterns are fixed on the display surface.

[0022] Combined with the second implementation manner of the first aspect, the present invention provides a sixth implementation manner of the first aspect. The pointer rotates periodically in a circular shape at the connection with the output shaft. A track is provided on the outer circle of the movement trajectory of the indicating end of the pointer, and the target is detachably fixed on the track.

[0023] Combined with the first to third and sixth implementation manners of the first aspect, the present invention provides a seventh implementation manner of the first aspect. A telescopic mechanism is provided on the target, and the distance between the target and the fixed plane is adjusted through the telescopic mechanism.

[0024] Combined with the first aspect, the present invention provides an eighth implementation manner of the first aspect. The display interface is a screen, and self-luminous or projected targets and indicating identifiers are provided on the screen.

[0025] Combined with the eighth embodiment of the first aspect, the present invention provides a ninth embodiment of the first aspect, where the indicating identifier is the pointer of a clock and rotates at a constant speed in a clockwise direction, and the target object is a plurality of display objects that appear outside the pointer at equal central angle intervals.

[0026] The beneficial effects of the present invention are as follows:

[0027] By using the cooperation of the indicating identifier moving at a constant speed and the target object, the present invention enables the concentration of the trainee to reach the limit, thereby mobilizing the reactions of the eyes and the surrounding muscles and nerves, and finally achieving the effect of improving the naked eye vision; synchronously training the vision and focus, comprehensively training to improve the naked eye vision, and having a good effect on improving the naked eye vision.

[0039] Embodiment 1:

[0040] This embodiment discloses a system for assisting training to improve naked eye vision. The system includes a fixed plate 1, and the fixed plate 1 is as Figure 2 and Figure 3 shown and is arranged on a movable bracket. A through hole is provided in the middle of the fixed plate 1, and a stepping motor is provided on the back of the fixed plate 1. The output shaft of the stepping motor passes through the fixed plate 1 and is connected to the front index. It is worth noting that this structure can be replaced by an existing clock with a second hand, but in order to improve the indication effect, a stepping motor is separately set as the power source, and the speed can be directly adjusted and the start and stop times can be set through a computer, which is more convenient.

[0041] On the front of the fixed plate 1, there is a pointer 2 sleeved on the output shaft of the stepping motor. The pointer 2 can rotate unidirectionally with the smallest rotation angle driven by the stepping motor, generally clockwise.

[0042] There is an orbit 3 provided on the outer circle of the pointer 2. The orbit 3 is of a circular structure, and a plurality of targets 4 are arranged at equal central angles on the orbit 3. In this embodiment, the targets 4 are plates of different shapes, and each plate is of similar size, and different stickers are pasted on its front to increase features for facilitating guiding and positioning.

[0043] The target 4 is directly clamped with the orbit 3, and an adjustable screwing mechanism is provided on the back of the target 4. When the target 4 slides on the orbit 3, after moving it to the set position, it is locked and fixed through the screwing mechanism. Thus, it matches the pointer 2 so that the pointer 2 can accurately point to each target 4.

[0044] At the same time, the target 4 can also be in the form of word cards or picture - text cards, etc., used to represent different objects, and the clarity is relatively high, avoiding the blurred pictures from affecting the training effect instead.

[0045] In order to further improve the training efficiency and reduce the labor cost at the same time, a voice broadcast structure is also provided on the fixed plate 1. It is connected to the computer through the voice broadcast structure and is uniformly controlled by the computer. After confirming the movement position and speed of the pointer 2, it can guide the trainees to aim their eyes at the corresponding target 4 according to the set program by itself.

[0046] The training method of the clock for improving naked - eye vision in this embodiment includes the following steps:

[0047] Prepare a classroom, the fixed plate 1 and the targets 4. Divide the classroom into two equal parts, and set two relatively - arranged fixed plates 1 at the center of the classroom, and set desks and chairs in the fan - shaped area facing each fixed plate 1;

[0048] Set the targets 4 at appropriate positions on each fixed plate 1, connect the stepping motor arranged behind the fixed plate 1 to the computer, and set the computer program to control the stepping motor to move at a controlled speed, and send instructions through the voice - playing structure;

[0049] When the training starts, the pointer 2 starts to move. When the pointer 2 points to the target 4 that has been informed, the trainee should make a timely response and give the trainer a clear feedback so that the trainer can know whether the trainee has completed a single training process.

[0050] The trainee trains at most 1 - 2 times a day, at least 1 time a week, each training lasts for 5 - 30 minutes, and each instruction exchange lasts for 5 - 30 seconds.

[0051] It should be noted that during the training process, in order to improve the training effect, the trainees need to hold their eyes wide open with their hands and are not allowed to blink until they receive the instruction to close their eyes and rest. Specifically, during the training process, both eyes are trained by holding both eyes wide open with both hands, and one eye is trained by holding one eye wide open with one hand (the left eye is held open with the left hand, and the right eye is held open with the right hand).

[0052] Furthermore, in order to further improve the training efficiency and accurately obtain the training status of the trainees, circular seats are arranged within the same spacing range outside the bracket, and multiple buttons matching the shape or number of the target object 4 are arranged in the corresponding area of each seat, or a tablet computer is set up, and all the target object 4 icons in this training are shown in the corresponding program on it. When the instruction is given, the trainees will first find the corresponding target object 4 and simultaneously find the corresponding button or icon for that target object 4. When the pointer 2 exactly points to that target object 4, the trainees should promptly press the corresponding button or icon. The computer collects the feedback time and times of each trainee, so that after completing a cycle of training, the trainer can give guidance to each trainee. Compared with the way of directly raising a hand to signal, this method can quickly and accurately obtain whether each trainee has observed and focused according to the voice instruction.

[0053] Furthermore, in this embodiment, in order to further improve the training effect, a telescopic structure is added to the back of the target object 4, and the distance between different target objects 4 and the trainees is adjusted through the telescopic structure. In this setting method during training, the trainees can continuously change the focal length, further increasing the movement amplitude of the eyeballs.

[0054] Embodiment 2:

[0055] This embodiment also discloses a system for assisting in training to improve the naked eye vision. Different from Embodiment 1, the system in this embodiment directly adopts the form of a projector and a screen. As Figure 1 shown, a screen is provided on the bracket, and a projector is provided in the middle of the circular table outside the screen. The projector is controlled by a computer to form a corresponding display interface on the screen.

[0056] It can be seen that, the same as in Embodiment 1, a clock-style indication mark is also shown in the screen, and multiple target objects 4 are also provided. Since it is computer virtual imaging, the target object 4 can be a photo of a real object, and by setting appropriate brightness and clarity, it is easier for the trainees to determine its features.

[0057] The training method for a clock related to improving the naked eye vision includes the following steps:

[0058] 1) Project a clock through a projection device or display a clock through a display screen;

[0059] 2) Guide the trainees to find their suitable positions;

[0060] 3) Announce the training content and rules to the trainees through computer software devices;

[0061] 4) When the pointer 2 points to the marker informed by the trainer, the trainees should respond in a timely manner; The trainees train 1 - 2 times a day, each training session lasts for 5 - 30 minutes, and each instruction exchange lasts for 5 - 30 seconds.

[0062] Similarly, the same as in the above Embodiment 1, during the training process of step 4, the trainees must hold their eyes wide open with their hands and cannot blink until they are instructed to close their eyes and rest.

[0063] Furthermore, during the training process of step 4, both eyes are trained by holding both eyes wide open with both hands, and one eye is trained by holding one eye wide open with one hand (hold the left eye open with the left hand and the right eye open with the right hand).

[0064] During the training process of this training method, the trainer should always ask the trainees about the condition of their eyes and observe the condition of the trainees' white eyeballs. If any abnormality is found, the training should be stopped immediately; During the training process, rules include not being allowed to talk, not being able to respond wrongly, not being able to do anything unrelated to the training, and if there is any discomfort in the eyes, tell the trainer immediately; After the trainees have practiced for a period of time, the trainer should change the markers at irregular intervals.

[0065] In order to make different target objects 4 have different focal lengths, the projection screen method can be changed to a display with a naked-eye 3D function, and different virtual target objects 4 with different focal lengths are displayed through this display, which can also improve the training effect.

[0066] The present invention is not limited to the above optional embodiments, and anyone can obtain other various forms of products under the inspiration of the present invention. The above specific embodiments should not be construed as limiting the protection scope of the present invention. The protection scope of the present invention should be defined by the claims, and the description can be used to interpret the claims.
