Description

Technical Field

[0001] The utility model belongs to the technical field of optical equipment, and particularly relates to a pair of glasses for vision training. Background Art

[0002] The vision training instruments currently on the market are generally bulky, occupy a large space, and are expensive, which is not convenient for users to train their vision. Most vision training zoom glasses adopt a double-layer lens structure, which is heavy to wear and not suitable for long-term wear or training. It is easy to cause users to wear fatigue, resulting in poor vision training effects. At the same time, the imaging effect is not good, and there are breakages and unevenness during the degree conversion and switching process. In addition, the existing lenses generally adopt a structure in which the left and right lenses are relatively fixed. The distance between the left and right lenses cannot be adjusted according to the user's pupil distance, and it cannot simultaneously ensure that the optical axes of the left and right lenses are directly aligned with the user's pupils, which seriously affects the quality of vision imaging and even causes vision damage.

[0003] In addition, the existing vision training varifocal glasses are inconvenient to wear due to their double-layer structure, shape and weight. Users only wear them when doing vision training. They cannot be used as glasses for daily use and need to wear additional corrective glasses.

[0004] Therefore, it is necessary to design a pair of glasses for vision training that are easy to wear, highly flexible to use, and have both pupil distance adjustment and focusing functions. Summary of the invention

[0035] like Figure 1~Figure 4 As shown, the utility model provides a pair of glasses for vision training, comprising a frame 1, a driving assembly 2 arranged inside the frame 1, and a lens assembly 3 arranged below the frame 1 and connected to the driving assembly 2, wherein the lens assembly 3 comprises a distance adjustment box block 31, and a left lens 32 and a right lens 33 respectively arranged on both sides of the distance adjustment box block 31, and the left lens 32 and the right lens 33 are both movably connected to the distance adjustment box block 31 to adjust the pupil distance of the lenses, that is, the distance between the optical centers of the left lens 32 and the right lens 33, so as to adapt it to the pupil distance of the user, so as to avoid the error between the pupil distance of the lenses and the pupil distance of the user affecting the imaging quality.

[0036] Specifically, a pitch-adjusting gear 311, a front pitch-adjusting rack 312, and a rear pitch-adjusting rack 313 are provided inside the pitch-adjusting box block 31.

[0037] The outer side of the front distance adjustment rack 312 is provided with a marking scale 314, and the outer side of the rear distance adjustment rack 313 is provided with a marking scale 314, so as to accurately adjust the pupil distance of the lens according to the user's pupil distance measurement result.

[0038] The left lens 32 includes an adjacent left first arc segment 321 and a left second arc segment 322, and the right lens 33 includes an adjacent right first arc segment 331 and a right second arc segment 332; there is a difference in refractive power between the left first arc segment 321 and the left second arc segment 322, and there is a difference in refractive power between the right first arc segment 331 and the right second arc segment 332, and the difference between the two is exactly the same, so as to ensure that the degree of the left lens and the right lens changes synchronously during the focusing vision training, avoiding discomfort caused by the difference in degree change.

[0039] Optionally, in some embodiments, the diopter of the left and right eyes of the user is the same, in which case the diopter of the left first arc segment 321 is the same as the diopter of the right first arc segment 331 , and the diopter of the left second arc segment 322 is the same as the diopter of the right second arc segment 332 .

[0041] The driving assembly 2 is connected to the distance adjustment box block 31 to drive the lens assembly 3 to reciprocate horizontally to the left and right, thereby realizing the focusing and zooming function.

[0042] Specifically, the driving assembly 2 includes a micro motor 21, a transmission shaft 22 connected to the output shaft of the micro motor 21, a limit rod 23 parallel to the transmission shaft 22, and a transmission block 24 movably sleeved on the outer periphery of the transmission shaft 22 and the limit rod 23; the transmission shaft 22 and the limit rod 23 are arranged horizontally in the frame 1, the micro motor 21, the transmission shaft 22, and the limit rod 23 are fixedly arranged in the frame 1 through the fixed support plates on the left and right sides, and the bottom of the transmission block 24 is connected to the top of the distance adjustment box block 31.

During the rotation of the micro motor 21, the transmission shaft 22 is driven to rotate, and the driving coupling piece 241 threadedly connected to the transmission shaft 22 moves horizontally and pushes the transmission block 24 to move horizontally. The forward and reverse switching motion of the micro motor 21 can realize the reciprocating motion of the transmission block 24. It should be noted that the forward and reverse micro motor belongs to the mature existing technology, and its specific structure will not be described here one by one.

[0043] The driving assembly 2 also includes a rechargeable battery disposed inside the frame 1, and the rechargeable battery is electrically connected to the micro motor 21.

Users can train freely, thereby effectively exercising the ciliary muscles, improving the adjustment ability of the ciliary muscles, relieving wearing and visual fatigue, improving the effect of vision training, and avoiding the deepening of myopia or presbyopia.
