Description

Technical Field

[0001] This utility model belongs to the field of vision correction technology, specifically relating to a vision function training device. Background Technology

[0002] In daily life, people frequently use their eyes to acquire knowledge and information. As the intensity of eye use gradually increases, the eye's accommodative ability gradually declines, often leading to eye symptoms such as myopia and presbyopia. To alleviate these symptoms, vision can be improved by exercising the eye muscles. For example, training the eye muscles through inward and outward rotation exercises the ciliary and medial rectus muscles, which are responsible for vision, by constantly moving the visual axes of both eyes. This coordinated exercise relieves muscle paralysis and stiffness, improving the eye muscles' accommodative ability and ultimately achieving clear imaging of objects on the retina, thus improving vision. Therefore, to alleviate the aforementioned eye symptoms, there is an urgent need for a vision training device that improves vision by exercising the eye muscles. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a visual function training device to solve the technical problem of exercising eye muscles.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a visual function training device, comprising:

[0006] A sight beacon is detachably installed in the housing, and a plurality of sight lights are arranged at intervals along its length on the sight beacon;

[0007] A circuit board, disposed in the housing, is used for electrical connection with each of the beacon lights;

[0008] The controller, mounted on the housing and electrically connected to the circuit board, is used to control each of the sight lights to light up or turn off sequentially in a preset time sequence along the direction toward or away from the observation window.

[0032] like Figures 1 to 4 As shown, this embodiment proposes a visual function training device, including a housing 1, the interior of which is hollow, and an observation window 2 on which the interior of the housing 1 can be observed. A visual target plate 3 is detachably installed in the housing 1, and multiple visual target lights 31 are spaced apart along the length of the visual target plate 3. In addition, a circuit board is provided in the housing 1, which is electrically connected to each visual target light 31. Furthermore, a controller 4 is provided in the housing 1, which is electrically connected to the circuit board. The controller 4 can be used to control the visual target plate 3 to light up or turn off one by one in a preset sequence in the direction toward or away from the observation window 2. The controller 4 controls the visual target lights 31 on the visual target board 3 to light up or turn off one by one in a preset sequence along the direction towards or away from the observation window 2. That is, when the next visual target light 31 lights up, the previous visual target light 31 turns off at the same time. This creates a light source similar to the visual target light 31 that can move along the length of the visual target board 3. By watching the movement of the visual target light 31, the user's eyes are prompted to make coordinated adjustments from far to near and from near to far, thereby exercising the eye muscles and improving vision.

[0033] In this application, the working principle of the vision training device is as follows:

[0034] When vision correction training is needed, the controller 4 controls each visual target light 31 on the visual target board 3, so that the visual target lights 31 light up one by one in a preset sequence along the direction towards or away from the observation window 2. It should be emphasized that when the next visual target light 31 lights up, the previous visual target light 31 turns off at the same time, so that the visual target light 31 moves from the farthest end towards the observation window 2 to the near end. When the user looks at the lit visual target light 31, the eye achieves linkage adjustment from far to near and from near to far as the light source of the visual target light 31 moves, thereby exercising the eye muscles (ciliary muscle, lens and medial rectus muscle), improving the eye's accommodation and convergence ability, and thus improving vision.

[0035] Preferably, in this embodiment, the preset timing sequence can be set to 3 seconds, 4 seconds, 5 seconds, etc. That is, when the preset timing sequence is 3 seconds, when a certain beacon light 31 is lit for 3 seconds and then turns off, the next beacon light 31 will light up synchronously, and so on, thereby realizing the movement of the beacon light 31 light source. Of course, in this embodiment, the preset timing sequence can also be set to other values ​​according to the actual situation and specific needs, and is not limited here.

[0036] Further, please refer to Figure 2 As shown, the housing 1 has multiple support plates 5 spaced apart along its length, and each support plate 5 has a step 51. The target plate 3 can be snapped onto the step 51 through the step 51, so as to realize the fixed installation of the target plate 3, which is simple and convenient; the detachable installation method can facilitate the replacement and maintenance of the target plate 3.

[0037] Furthermore, the housing 1 is provided with a scale, which corresponds to the position of each visual target light 31. By setting the scale, it is convenient to analyze the user's vision correction and detect the effect of vision training.

[0038] In this application, when a nearsighted user looks at an illuminated target light through an observation window, the target light will appear as a double image (i.e., two light sources are observed) when it is at a distant point in the observation window. As the light source in the target light 31 moves, the double image disappears when it reaches a certain position (i.e., only one light source is observed). The user's current vision can be initially assessed by the scale value corresponding to the light source of the illuminated target light 31. After the user has been training by looking at the target light 31 for a period of time, the position where only one light source is observed by both eyes will shift. The position of the shift can be quickly and conveniently determined by the scale value corresponding to the target light 31, thereby quickly judging the user's vision correction status.

[0039] Preferably, the visual target lights 31 are equidistantly distributed along the length of the visual target plate 3. This equidistant distribution facilitates the observation and analysis of visual correction.

[0040] Further, please refer to Figure 1 As shown, the controller 4 includes a control box 41, which is located on one side of the bottom of the housing 1. The control box 41 contains a control board (not shown in the attached diagram), which is electrically connected to the circuit board. Furthermore, the control box 41 has a start / stop switch 42, which is electrically connected to the control board. Thus, by controlling the start / stop switch 42, the circuit can be turned on, thereby controlling the light source of the visual target lamp 31. The control box 41 also supports one side of the housing 1, facilitating vision training for the user through the observation window 2.

[0041] Further, please refer to Figure 4 As shown, a support frame 6 is also rotatably mounted on the control box 41. By rotating and adjusting the support frame 6, the height of the control box 41 can be adjusted according to actual needs, thereby meeting the needs of different users and enhancing the applicability of the device.

[0042] Further, please refer to Figure 1 As shown, the observation window 2 includes a frame 21, on which a pair of viewing windows 22 are spaced apart, and each viewing window 22 is respectively equipped with a corrective lens 23. By providing a pair of viewing windows 22, the user's two eyes can simultaneously observe the visual target light 31. Of course, in other embodiments, only one viewing window can be provided according to actual needs, which is not limited here. Preferably, the frame 21 is integrally formed with the housing 1, which can simplify subsequent machining and reduce production costs.

[0043] Preferably, the corrective lens 23 is a prism lens. By using a prism lens, the direction of light propagation can be changed through the prism, helping to adjust the line of sight so that it can be correctly focused on the retina, thereby correcting strabismus; at the same time, by adjusting the direction of light through the prism lens, both eyes can see a single clear image at the same time, thereby eliminating diplopia.

[0044] Further, please refer to Figure 4 As shown, the control box 41 is provided with heat dissipation holes 7. By providing heat dissipation holes 7, the heat dissipation effect of the device is enhanced, thereby increasing the service life of the product.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
