Abstract
Description
Technical Field
[0001] This invention relates to the field of vision correction training devices, and more particularly to a vision correction training device based on eye tracking. Background Technology
[0002] A vision training device is a medical device used to improve visual function, relieve eye strain, and assist in the treatment of amblyopia or accommodative dysfunction.
[0003] The use of fixed-specification vision training devices suffers from limited functionality; a single device can only train one type of vision condition. Furthermore, different individuals have varying heights, body shapes, and skeletal structures, making these devices inflexible. Therefore, those skilled in the art have developed an eye-tracking-based vision correction training device to address the problems described in the background section. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the background art by proposing a vision correction training device based on eye tracking.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a vision correction training device based on eye tracking, comprising a main structure, a vision training structure and an adjustment structure, wherein the main structure comprises a base, a motor located at the upper end of the base, a support plate located at the upper end of the motor, and a support column located at the upper end of the support plate; The vision training structure includes a training device body arranged in a ring array on the outside of the support column, a lens shell symmetrically distributed on one side of the training device body, and a lens opening at one end of the lens shell. The adjustment structure includes a side frame located on one side of the training device body, a mounting shaft rotatably installed inside the side frame, a center block located at one end of the mounting shaft and connected to the training device body, a torsion spring sleeved on the outside of the mounting shaft and connected at both ends to the center block and the side frame respectively, a support rod located below the mirror housing, support rods symmetrically distributed at the upper end of the training device body, and a sleeve located at one end of the support rod and sleeved on the outside of the support rod.
[0006] Preferably, the outer wall of the support plate is fitted with an annular track, and the upper end of the base is provided with an annular seat. A ball bearing, which is rotatably mounted inside the annular track, is mounted on the inner wall of the annular seat. The ball bearing and annular track structure converts sliding friction into rolling friction, reducing the resistance when the motor drives the support plate to rotate, avoiding the vibration caused by direct metal-to-metal contact in traditional bearings. The distributed contact between the annular track and the ball bearings ensures uniform force distribution on the support plate, preventing the training device body from shifting due to eccentric loads.
[0007] Preferably, one end of the training device body is provided with a soft pad that fits onto the outer wall of the mirror housing, one end of the training device body is provided with a support shaft, and the outer wall of the mirror housing is provided with a damping bushing that is rotatably fitted onto the outer wall of the support shaft.
[0008] Preferably, the outer wall of the support column has annularly distributed side grooves, and the inner wall of the side grooves is provided with guide rails. A slider connected to the side frame is slidably mounted at one end of the guide rail. Medical-grade silicone pads conform to the facial contours, distributing pressure on the lens housing and preventing pressure on the bridge of the nose or cheekbones during prolonged training, making it especially suitable for children's sensitive skin. The damping bushing provides stepless adjustable resistance, allowing for precise one-handed positioning of the lens housing and automatic angle maintenance, solving the problem of frequent calibration caused by loose traditional hinges. The pads provide a flexible seal against the face, blocking ambient light interference.
[0009] Preferably, the side groove is provided with bearing seats located on the upper and lower sides of the guide rail. A screw rod, threadedly connected to the slider, is rotatably mounted inside the bearing seat. A rotating rod arranged in a circular array is provided at the lower end of the screw rod. The guide rail and slider structure allows the training device body to move vertically along the column, supporting the expansion of multiple training devices as needed, such as red light / binocular vision / afterimage devices, avoiding the need for repeated purchases of complete units. The bearing seats provide rotational support for the screw rod, which rotates by gripping the rotating rod, facilitating the application of rotational force.
[0010] Preferably, a guide frame is provided at one end of the training device body, a sliding sleeve is embedded inside the guide frame, a guide rod is slidably inserted inside the sliding sleeve, a square groove is opened at one end of the bearing seat, and a square block is provided at one end of the guide rod, which is inserted into the square groove. The guide rod is slidably guided inside the guide frame through the sliding sleeve, and can be slidably inserted into the square groove every 90 degrees of rotation.
[0011] Preferably, a handle is provided at one end of the guide rod, and a support ring is sleeved on the outer wall of the guide rod. A spring is provided between the support ring and the guide frame, sleeved on the outside of the guide rod. The handle facilitates the application of gripping force to the guide rod, and the support ring provides elastic support to the spring, so that the guide rod is supported by elastic force. When the guide rod drives the block to align with the square groove, it achieves elastic positioning.
[0012] Preferably, the upper end of the sleeve has an internal mounting groove, the upper inner wall of the mounting groove is provided with a spring, the lower end of the spring is provided with a locking block, the upper end of the support rod has equidistantly distributed locking slots, the inner wall of the sleeve's inner opening is provided with a retaining ring, and one end of the support rod is provided with a limiting ring. The locking structure of the locking block and the locking slots enables multi-position adjustment of the support rod to match different chin positions. The retaining ring and the limiting ring form a double mechanical stop to prevent the sleeve from accidentally falling off. The spring optimizes human-machine interaction; the sleeve can be unlocked by gently lifting it and automatically locked after being released, allowing nurses to adjust it with one hand.
[0013] Preferably, the upper end of the base is provided with a support frame, and the support frame has a screw hole inside. A second mounting screw is threaded into the screw hole. The outer wall of the second mounting screw has a ring-shaped array of second rotating rods. One end of the second mounting screw is rotatably sleeved with a rotating seat. One end of the rotating seat is provided with a positioning rod. A second sliding sleeve is embedded in the support frame. One end of the positioning rod is provided with a second guide rod that slides into the sliding sleeve. The positioning rod presses against the sternal manubrium, forcing the spine to remain upright and avoiding adjustment lag caused by forward tilting during myopia training. The second guide rod eliminates radial movement when the screw rotates, ensuring pure linear movement of the positioning rod. The large diameter design of the second rotating rod enables rapid coarse adjustment and is suitable for various scenarios such as wheelchairs and school desks and chairs.
[0014] Preferably, the steps for using the eye-tracking vision correction training device are as follows: S1: The support base is placed on a fixed platform. The motor then drives the support plate to rotate. As the support plate rotates, ball bearings within the guide rails enhance rotational stability. The motor adjusts the corresponding training device to the appropriate treatment position. The training device contains various built-in training equipment, including a red light flashing training device, a binocular vision function training device, and an afterimage enhancement training device. The chin is supported by multiple rods and located inside the bracket. The glasses correspond to the lens opening, and the skin around the eyes fits snugly against the soft padding. This allows for tracking and training of different eye conditions. The lens shell is supported by a damping bushing. The outer wall of the shaft rotates to adjust the rotation distance of the mirror housing. The damping component inside the damping bushing enables the mirror housing to be positioned after adjustment. The shielding cloth sleeve is located in the movement space of the mirror housing and blocks external light. The drag bar slides on the outer wall of the support rod through the sleeve to adjust the horizontal position of the drag bar. By pulling the sleeve, the locking block is squeezed, and the locking block squeezes the first spring. The first spring is forced to drive the locking block to be stored in the mounting groove. After the locking block is aligned with the corresponding locking groove, it achieves elastic locking and positioning, providing a chin placement position for people who may have forward head tilt. S2: During the use of the training instrument, first rotate the training instrument from inside the side slot upwards. The training instrument drives the mounting shaft to rotate inside the side frame through the center block. At the same time, a torsional force is applied to the torsion spring, which is forced to twist. Simultaneously, the handle is gripped to drive the guide rod one to rotate. After the training instrument rotates 90 degrees, the guide rod one is supported by the elastic force of the spring two. The guide rod one slides inside the guide frame through the sliding sleeve one, and a sliding placement groove is obtained on one side of the training instrument. After the block is inserted into the square groove at one end of the bearing seat, the mounting shaft is limited to prevent the mounting shaft from rotating due to the elastic support of the torsion spring, thus ensuring that the training instrument is in a horizontal position. S3: Simultaneously, gripping the first rotary rod drives the first screw to rotate. The slider is guided longitudinally by the guide rail, pushing the slider to move longitudinally, which in turn drives the side frame and the training device body to move longitudinally, enabling the training device body to adjust its height. The support rod moves synchronously with it, realizing the height adjustment of the training device body to adapt to people of different heights. At the same time, gripping the second rotary rod drives the second screw to rotate inside the screw hole. The positioning rod slides inside the second sliding sleeve through the second guide rod, guiding the positioning rod. The rotational force of the screw inside the screw hole acts on the rotating seat, driving the positioning rod to move. The positioning rod contacts the chest position of the person who needs vision training in a seated position, supporting their chest position and forcing the person who needs vision training to straighten their spine, ensuring a straight sitting posture and correcting the standard of the person who needs vision training during vision tracking training.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The support column of this invention has multiple training device bodies inside the upper end. The training device bodies include red light flashing type training device, binocular vision function training device and afterimage enhancement type training device. The corresponding training device body can be adjusted to the use position through the bottom rotatable adjustment component. It can provide targeted vision tracking and correction training for central fixation amblyopia, eccentric fixation amblyopia, visual dysfunction and visual fatigue, and improve the flexibility of vision correction. Meanwhile, during use, the distance between the eyes, the height of the training device, and the degree of chest expansion can be adjusted. The chin is supported during use, improving the comfort of the training process. After use, the training device can be stored away, improving the comfort and convenience of using the device. After use, the device occupies less storage space and is easy to store. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1 to 10 The present invention provides four embodiments: Example 1: A vision correction training device based on eye tracking includes a main structure 100, a vision training structure 200 and an adjustment structure 300. The main structure 100 includes a base 101, a motor 103 located at the upper end of the base 101, a support plate 104 located at the upper end of the motor 103, and a support column 107 located at the upper end of the support plate 104. The vision training structure 200 includes a training device body 201 arranged in a ring array on the outside of the support column 107, a lens shell 202 symmetrically distributed on one side of the training device body 201, and a lens opening 204 located at one end of the lens shell 202. The outer wall of the support plate 104 is fitted with a ring rail 106 in the shape of a ring, and the upper end of the base 101 is provided with a ring seat 102. The inner wall of the ring seat 102 is rotatably mounted with balls 105 that are rolled inside the ring rail 106. In this embodiment, the base 101 is fixed to the table surface, and the motor 103 is started to drive the support plate 104 to rotate. The ball bearings 105 roll smoothly in the annular guide rail 306, reducing frictional resistance. The rotation is completed when the target training device body 201 is reached. The red light flashing training device, binocular vision function training device, and afterimage enhancement training device are facing the user to address different vision problems such as amblyopia and eye fatigue. The user's chin is placed in the groove 304 of the support rod, and the face is in contact with the medical silicone soft pad 206 on the outer wall of the lens shell 202. The lens opening 204 is aligned with the eyes. The opening angle of the lens shell 202 is adjusted by the damping bushing 205 to adapt to different interpupillary distances. The sleeve 302 is lifted to compress the spring 312, causing the locking block 311 to disengage from the support. The lever 301 has a slot 308. After the horizontal sliding lever is released to a comfortable position under the chin, the locking block 311 automatically pops into the corresponding slot 308 to lock it in place. The shielding cloth cover 207 unfolds to cover the active area of the lens shell 202, blocking ambient light interference. The three training modules distributed in a ring, such as amblyopia type and visual fatigue, are switched by the motor 103, solving the problem of the single function of traditional equipment. The soft pad 206 disperses pressure to avoid pressure marks on children's faces. The damping bushing 205 achieves stepless adjustment and self-locking, replacing the traditional loose hinge. The lever elastic buckle mechanism supports one-handed operation and accurately matches different face shapes. The soft pad 206 and the flexible face seal combined with the shielding cloth cover 207 ensure the effectiveness of optical training, such as the need to block ambient light for red light flashing therapy. It is worth noting that the core of the red light flashing training device is an LED light that emits a specific wavelength, usually 630-650nm red-orange light. The device includes lenses and mirrors to focus the light or form specific patterns. The internal pattern disk is a transparent plate that can be rotated or replaced. It is printed with fine visual targets such as gratings, E-shapes, graphics, and animal patterns to control the flashing frequency, brightness, and training time of the light source. The specific wavelength of red light can stimulate the cone cells in the fovea of the macula, especially the cells that are sensitive to red light, increasing their sensitivity and activity. The flashing stimulation can promote the excitability and conduction efficiency of neurons in the visual pathway. Fine visual target training forces the amblyopic eye to perform fine recognition, stimulating visual development. It is mainly used as an adjunct treatment for central fixation amblyopia. Afterimage vision enhancement training devices involve the patient fixating on a central black dot with the amblyopic eye. Strong light is shone on the peripheral retina, causing it to inhibit the retina. The fovea, protected by the black dot, is not stimulated by the strong light. After the light source is turned off, the patient will see a "positive afterimage" with a bright center and a dark periphery. During this afterimage, the fovea is in a relatively dominant state, allowing the patient to identify fine visual targets placed in front of their eyes, such as white walls or white paper, small E-shaped objects, numbers, etc. This forces the patient to fixate on the fovea and is mainly used to correct eccentric fixation amblyopia. Binocular vision training devices can be selected from various types, such as convergence balls, slit rulers, synoptophores, reversal cameras, and digital training. The main structure includes a convergence ball consisting of several colored balls strung on a rope, a ruler with a movable slit plate, two independent lens tubes with adjustable angles to present different images, and a set of flip lenses with different positive and negative powers. By designing specific visual tasks, such as convergence and divergence training, accommodative flexibility training, fusion training, disinhibition training, and hand-eye coordination training, it stimulates and improves the ability of the eyes to work together. It is mainly used for visual dysfunction, such as accommodative insufficiency, convergence insufficiency, fusion disorder, binocular vision reconstruction in the later stages of amblyopia, and relief of visual fatigue. Example
[0020] The adjustment structure 300 includes a side frame 314 located on one side of the training instrument body 201, a mounting shaft 316 rotatably installed inside the side frame 314, a center block 317 located at one end of the mounting shaft 316 and connected to the training instrument body 201, a torsion spring 315 sleeved on the outside of the mounting shaft 316 and connected at both ends to the center block 317 and the side frame 314 respectively, a support rod located below the mirror housing 202, a support rod 301 symmetrically distributed at the upper end of the training instrument body 201, and a sleeve 302 located at one end of the drag rod 303 and sleeved on the outside of the support rod 301. One end of the training device body 201 is provided with a soft pad 206 that is sleeved on the outer wall of the mirror shell 202, and one end of the training device body 201 is provided with a support shaft 203. The outer wall of the mirror shell 202 is provided with a damping bushing 205 that is rotatably sleeved on the outer wall of the support shaft 203. The training instrument body 201 has a guide frame 323 at one end, a sliding sleeve 321 is embedded inside the guide frame 323, a guide rod 325 is slidably inserted inside the sliding sleeve 321, a square groove 332 is opened at one end of the bearing seat 333, and a square block 318 is inserted into the square groove 332 at one end of the guide rod 325. A handle 322 is provided at one end of the guide rod 325, and a support ring 319 is sleeved on the outer wall of the guide rod 325. A spring 320 is provided between the support ring 319 and the guide frame 323 and sleeved on the outside of the guide rod 325. In this embodiment, the training device body 201 is flipped upwards by 90 degrees. The center block 317 drives the mounting shaft 316 to rotate within the side frame 314. The torsion spring 315 stores energy and simultaneously grips the handle 322 to pull the guide rod 325 outwards, compressing the spring 320. This causes the block 318 at the end of the guide rod 325 to disengage from the bearing seat 333 and the square groove 332. When the training device body 201 is rotated to a horizontal position, the handle 322 is released. The spring 320 pushes the block 318 into the square groove 332 to form a mechanical hard limit. The rebound force of the torsion spring 315 is completely constrained by the structure of the block 318 and the square groove 332, ensuring the stable horizontal posture of the device. The torsion spring 315 provides the return force, saving longitudinal space when storing. The spring 320 automatically resets the block 318 to the square groove 332, replacing manual bolt fixing. The limiting structure bears all the rebound force of the torsion spring 315, preventing accidental folding during training. Example
[0021] The outer wall of the support column 107 is provided with a side groove 108 distributed in a ring. The inner wall of the side groove 108 is provided with a guide rail 306. One end of the guide rail 306 is slidably installed with a slider 313 connected to the side frame 314. The side groove 108 is provided with bearing seats 333 located on the upper and lower sides of the guide rail 306. The bearing seats 333 are rotatably installed with screws 305 that are threadedly connected to the slider 313. The lower end of the screws 305 is provided with rotating rods 324 arranged in a ring array. The upper end of the sleeve 302 has an installation groove 310 inside. The upper inner wall of the installation groove 310 is provided with a spring 312. The lower end of the spring 312 is provided with a locking block 311. The upper end of the support rod 301 has equally spaced locking grooves 308 inside. The inner wall of the opening of the sleeve 302 is provided with a retaining ring 307. One end of the support rod 301 is provided with a limit ring 309. A support frame 329 is provided on the upper end of the base 101. A screw hole 331 is opened inside the support frame 329. A second mounting screw is threaded into the screw hole 331. A second rotating rod 330 is arranged in a ring array on the outer wall of the second screw. A rotating seat 327 is rotatably sleeved at one end of the second screw. A positioning rod 326 is provided at one end of the rotating seat 327. A second sliding sleeve is embedded in the support frame 329. A second guide rod 328 is slidably inserted into the sliding sleeve at one end of the positioning rod 326. In this embodiment, the rotating rod 324 drives the screw, which in turn moves the side frame 314 and the training device body 201 vertically along the guide rail 306 via the slider 313. The support rod rises and falls synchronously. The rotating rod 330 pushes the screw 331 to move within the screw hole 331. The guide rod 328 slides within the sliding sleeve 328 for guidance. The positioning rod 326 abuts against the user's sternum and continues to rotate until the spine remains upright. The screw drive achieves micron-level positioning, covering different heights. The double bearing seat 333 bears the axial load to prevent settlement. The positioning rod 326 at the sternum provides forced support. The open chest cavity reduces cervical spine forward tilt, and the guide rod 328 and sliding sleeve 2 eliminate radial movement, ensuring pure linear motion of the positioning rod 326. The large-diameter rotating rod 330 enables rapid adjustment, adapting to various scenarios such as desks and wheelchairs. Traditional equipment only supports a single training mode, while the motor 103 drives switching to quickly meet the needs of different eye training, solving the problem of insufficient human adaptation for different groups. The lens shell 202 damping adjusts the interpupillary distance, the support rod buckle positions the face shape, adjusts the height, and adjusts the chest support. The entire adjustment process requires no additional tools, significantly improving treatment efficiency and flexibility. Example
[0022] The steps for using the eye-tracking vision correction training device are as follows: S1: The support base is placed on a fixed platform. Then, the motor 103 drives the support plate 104 to rotate. When the support plate 104 rotates, the ball bearings 105 rotate inside the guide rail 306 to improve rotational stability. The motor 103 adjusts the corresponding training device body 201 to the corresponding treatment position. The training device body 201 has different built-in training devices, namely a red light flashing training device, a binocular vision function training device, and an afterimage enhancement training device. The chin is supported by multiple rods and is located inside the bracket 304. The glasses correspond to the lens opening 204. The skin of the eye area is in contact with the soft pad 206 to track and train different eye conditions. The lens shell 202 rotates on the outer wall of the support shaft 203 through the damping bushing 205. The rotation distance of the mirror housing 202 is adjusted. The damping element inside the damping bushing 205 enables the mirror housing 202 to be positioned after adjustment. The shielding cloth 207 is located in the moving and lifting space of the mirror housing 202, while blocking the outside light. The drag rod 303 slides on the outer wall of the support rod 301 through the sleeve 302, and the horizontal position of the drag rod 303 can be adjusted. By pulling the sleeve 302, the locking block 311 is pressed. The locking block 311 presses the spring 312. The spring 312 is forced to drive the locking block 311 into the mounting groove 310. After the locking block 311 is aligned with the corresponding slot 308, it achieves elastic locking and positioning, providing a chin placement position for people who may have forward head tilt. S2: During the use of the training instrument body 201, the training instrument body 201 is first rotated upward from inside the side groove 108. The training instrument body 201 drives the mounting shaft 316 to rotate inside the side frame 314 through the center block 317. At the same time, a torsional force is applied to the torsion spring 315, which is forced to twist. Simultaneously, the grip handle 322 drives the guide rod 325 to rotate. After the training instrument body 201 rotates 90 degrees, the guide rod 325 is supported by the elastic force of the spring 320. The guide rod 325 slides inside the guide frame 323 through the sliding sleeve 321, and obtains a sliding placement groove on one side of the training instrument body 201. After the block 318 is inserted into the square groove 332 at one end of the bearing seat 333, it limits the mounting shaft 316 to prevent the mounting shaft 316 from rotating due to the elastic support of the torsion spring 315, thus ensuring that the training instrument body 201 is in a horizontal position. S3: Simultaneously, gripping the first rotating rod 324 drives the first screw 305 to rotate. The slider 313 is guided longitudinally by the guide rail 306, pushing the slider 313 to move longitudinally, thereby driving the side frame 314 and the training device body 201 to move longitudinally, causing the training device body 201 to adjust its height. The support rod moves synchronously with it, realizing the height adjustment of the training device body 201 to adapt to people of different heights. At the same time, gripping the second rotating rod 330 drives the second screw to rotate inside the screw hole 331. The positioning rod 326 slides inside the second sliding sleeve through the second guide rod 328, guiding the positioning rod 326. The rotational force of the screw inside the screw hole 331 acts on the rotating seat 327, driving the positioning rod 326 to move. The positioning rod 326 contacts the chest position of the person who needs vision training in a sitting position, supporting their chest position, forcing the person who needs vision training to straighten their spine, ensuring a straight sitting posture, and correcting the standardization of the person who needs vision training during vision tracking training.

10. A vision correction training device based on eye tracking according to claim 1, characterized in that: The steps for using the eye-tracking vision correction training device are as follows: S1: The support base is placed on a fixed platform, and then the motor (103) drives the support plate (104) to rotate. When the support plate (104) rotates, the ball bearings (105) rotate inside the guide rail (306) to improve the rotational stability. The motor (103) adjusts the corresponding training device body (201) to the corresponding treatment position. The training device body (201) has different training devices built in it, namely a red light flashing training device, a binocular vision function training device and an afterimage enhancement training device. The chin is supported by a multi-rod and is located inside the bracket (304). The glasses correspond to the lens opening (204). The skin of the eye area is in contact with the soft pad (206) to track and train different eye conditions. The lens shell (202) rotates on the outer wall of the support shaft (203) through the damping bushing (205) to adjust the lens shell ( 202) Adjust the rotation distance. The damping element inside the damping bushing (205) makes the mirror housing (202) positioned after adjustment. With the shielding cloth (207) in the mirror housing (202) moving and lifting the activity space, it blocks the light from the outside. The drag bar (303) slides on the outer wall of the support rod (301) through the sleeve (302). The horizontal position of the drag bar (303) can be adjusted. The pull sleeve (302) squeezes the locking block (311). The locking block (311) squeezes the spring (312). The spring (312) is forced to drive the locking block (311) to be stored in the mounting groove (310). After the locking block (311) corresponds to the corresponding slot (308), it achieves elastic locking and positioning, providing a chin placement position for people who may have forward head tilt. S2: During the use of the training instrument body (201), firstly, rotate the training instrument body (201) upward from inside the side slot (108). The training instrument body (201) drives the mounting shaft (316) to rotate inside the side frame (314) through the center block (317), and at the same time, apply a torsional force to the torsion spring (315). The torsion spring (315) is forced to twist. At the same time, grip the handle (322) to drive the guide rod (325) to rotate. After the training instrument body (201) rotates ninety degrees, the guide rod (325) rotates. (325) Because it is supported by the elastic force of spring two (320), the guide rod one (325) slides inside the guide frame (323) through the sliding sleeve one (321) and gets a sliding placement groove on one side of the training instrument body (201). After the block (318) is inserted into the square groove (332) at one end of the bearing seat (333), it limits the mounting shaft (316) to prevent the mounting shaft (316) from being elastically supported and rotated by the torsion spring (315), and ensures that the training instrument body (201) is in a horizontal position. S3: Simultaneously, gripping the first rotating rod (324) drives the first screw (305) to rotate. The slider (313) is guided longitudinally by the guide rail (306), pushing the slider (313) to move longitudinally, thereby driving the side frame (314) and the training instrument body (201) to move longitudinally, driving the training instrument body (201) to adjust its height. The support rod moves synchronously with it, realizing the height adjustment of the training instrument body (201) to adapt to people of different heights. At the same time, gripping the second rotating rod (330) drives the second screw inside the screw hole (331). Rotation causes the positioning rod (326) to slide inside the sliding sleeve via the guide rod (328), guiding the positioning rod (326) to slide. The screw's rotational force inside the screw hole (331) is applied to the rotating seat (327), causing the positioning rod (326) to move. The positioning rod (326) then contacts the chest of the person requiring vision training in a seated position, supporting their chest and forcing them to straighten their spine, ensuring a straight sitting posture and correcting the lack of standardization in the vision tracking training process.
