Description

Technical Field

[0001] The utility model belongs to the technical field of vision training, and particularly relates to a vision training device. Background Art

[0002] With the development of society, electronic products are becoming increasingly popular. Electronic products such as mobile phones and computers are used more and more frequently in people's daily work and life. Especially for children and teenagers, in their study and after-school entertainment activities, due to the failure to adhere to good reading and viewing habits, the myopia rate of children and teenagers is increasing year by year. The reason is that when people use electronic devices such as mobile phones and computers for a long time, the eyeballs will directly face the screen for a long time, causing the ciliary muscles of the eyeballs to become over-fatigued, and then gradually losing their due elasticity, resulting in the inability of the lens to recover, and further leading to the occurrence of eye diseases such as myopia.

[0003] Currently, the main means to solve myopia is to wear myopia glasses. Although myopia glasses can play a role in vision correction, there are also problems such as the continuous deepening of vision during wearing and being easily soiled, which affects the clear vision. Although some vision correction training devices have emerged on the market, these correction training devices have relatively fixed correction lens degrees and cannot meet the correction needs of different myopic patients, so their universality is poor. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a vision training device to solve the technical problem of poor universality of the existing vision correction training devices.

[0015] Further, the number of the lens discs is two. The two lens discs are slidably mounted in the housing, and a pupil distance adjustment assembly for adjusting the relative distance between the two lens discs is provided in the housing.

[0016] Further, the pupil distance adjustment assembly includes a first rack and a second rack respectively connected to a pair of the lens discs, a gear meshing with the first rack and the second rack respectively, and a knob for driving the gear to rotate. An opening for the knob to protrude is formed on the housing.

[0037] As Figures 1 to 6As shown, this embodiment provides a vision training device, including a housing 1. The interior of the housing 1 is hollow, and a pair of through holes 11 are spacedly provided on the housing 1. In addition, a plurality of mirror discs 2 are provided in the housing 1. Each mirror disc 2 is spacedly arranged and rotatably installed in the housing 1. A plurality of accommodating units 21 are provided along the circumferential direction of each mirror disc 2. Each accommodating unit 21 can be rotated to a position corresponding to a pair of through holes 11. In addition, a plurality of training lenses 3 are detachably installed on each accommodating unit 2. The degrees of some of the training lenses 3 are different. In this way, by assembling a plurality of training lenses 3 with different degrees on each mirror disc 2, the two eyes of myopic patients can correct and train by looking at the training lenses 3 on each mirror disc 2 through a pair of through holes 11. When it is necessary to switch training lenses 3 with different degrees, only the mirror disc 2 needs to be rotated at this time, so that the accommodating unit 21 loaded with training lenses 3 with different degrees is rotated to the position of this pair of through holes 11 for myopic patients to perform correction training with different degrees. Through this training device, myopic patients with different degree requirements can be adapted, and the universality of the device is improved. At the same time, myopic patients can also perform progressive training for degree correction according to their own needs, that is, by gradually changing the degrees of the training lenses 3, stimulating the adjustment movement of the eyeballs, and then realizing the correction and adjustment of the patients' vision.

[0038] In this application, the degrees of the training lenses 3 installed in the accommodating units 21 on each mirror disc 2 can be completely the same or not completely the same. The degrees of some of the training lenses 3 in each accommodating unit 21 on each mirror disc 2 are different. In this application, the "some" can be a part or all, that is, the degrees of some of the training lenses 3 are different. It can be that the degrees of some of the training lenses 3 in each accommodating unit 21 are different, or all the training lenses 3 in each accommodating unit 31 are different.

[0039] Preferably, in this embodiment, the number of the accommodating units 21 on the mirror disc 2 is set to six. By setting six accommodating units 21, six different degrees of training lenses can be loaded on the mirror disc 2 to meet the needs of users for multiple degrees. Of course, in this embodiment, according to the actual situation and specific requirements, the number of the accommodating units 21 on the mirror disc 2 can also be set to eight, ten, etc., which is not uniquely limited here.

[0040] Further, please refer to Figure 4 and Figure 5 As shown, a first magnet (not shown in the drawings) is provided on the accommodating unit 21, and a second magnet (not shown in the drawings) is provided on the training lens 3. The first magnet and the second magnet are magnetically attracted to each other. In this way, by setting the magnetic attraction method, the training lens 3 can be quickly installed in the accommodating unit 21, which preferably improves the installation efficiency.

[0041] Preferably, please refer to Figure 4and Figure 5 As shown in Figure 5 , a first receiving groove 211 is formed in the receiving unit 21. The first magnet can be placed in the first receiving groove 211. Correspondingly, a second receiving groove 31 is formed in the training lens 3 at a position corresponding to the first receiving groove 211. The second magnet can be placed in the second receiving groove 31. By providing the first receiving groove 211 and the second receiving groove 31, the first magnet and the second magnet can be better fixed, preventing them from falling off during use.

[0042] Preferably, the number of the first receiving grooves 211 is multiple, and the first receiving grooves 211 are distributed at intervals in a circumferential direction of the receiving unit 21. Specifically, in the present application, the number of the first receiving grooves 211 is four, and the included angle between two adjacent first receiving grooves 211 is 90°. By setting the number of the first receiving grooves 211 to four, the first magnets can be respectively placed in the first receiving grooves 211. Correspondingly, the number of the second receiving grooves 31 can also be set to four, so that the second magnets can be respectively placed in the second receiving grooves 31. By magnetically attracting through multiple magnets at multiple angles, the bonding force between the training lens 3 and the receiving unit 21 can be further enhanced. Of course, in this embodiment, the number of the first receiving grooves 211 or the second receiving grooves 31 can be adjusted according to actual situations, and it is not limited uniquely here.

That is, according to user needs, the digital processor can store the response time of the lens disc 2 rotation, such as 3 min, 5 min, etc. That is, when the response time reaches the preset time, at this time the digital processor will activate the circuit board 152 to control the rotating member 4 to rotate, and the rotating member 4 controls the lens disc 2 to rotate. If the response time is 3 min, the lens disc can rotate once every 3 min; if the response time is 5 min, the lens disc can rotate once every 5 min, realizing the switching of training lenses with different degrees.
