Description

[TECHNICAL FIELD]

[0001] The utility model relates to visual correction product technical field, especially to a rotation switching type visual correction device with reasonable structure design and outstanding application effect. [BACKGROUND]

[0002] The visual correction reversing flip product in the visual correction device is also called flip or butterfly flip. In the specific structure component, it is generally composed of two pairs of positive and negative prisms with equal degrees and a handle. In actual use, a visual card is placed in front of the trainer, and the reversing flip is placed between the eyes of the trainer and the visual card. The two pairs of positive and negative prisms on the reversing flip are flipped back and forth through the handle. Under the condition that the trainer's eyes can read clearly every time, the number of changes from positive to negative within one minute is recorded.

[0003] With the development of science and technology, the popularity of television computers and the lack of sufficient outdoor activities make the eyes stay in a close visual state for a long time, which cannot effectively and sufficiently adjust the pupil distance. In particular, the heavy learning pressure also increases the myopia rate of students year by year. In this case, the visual correction reversing flip product emerges as the times require.

[0004] Compared with the existing visual correction instrument, the flip product can realize the adjustment of the distance, so as to achieve the purpose of correcting and protecting the vision by adjusting the visual state.

[0005] However, the existing flip product still has some deficiencies, such as the full open setting of positive and negative lenses, which can easily interfere with the user during actual use and affect the accuracy of correction.

[0006] For example, the Chinese utility model patent with the patent number 202320847379.4 and the patent name "a visual correction device" discloses the following content: a visual correction device, comprising: a shell, a sliding groove is formed on the surface of the shell, and a driving block is slidably connected inside the sliding groove; a panel is rotatably connected to one end of the shell, and a lens slot frame for placing magnifying lenses and reducing lenses is embedded inside the panel. The lens slot frame is used for clamping and placing magnifying lenses and reducing lenses. The shell is internally provided with a movable part connecting the panel and the driving block. The driving block is slid up and down in the sliding groove to drive the panel to rotate through the movable part. The rotation angle of the panel is 45 degrees. The visual correction device can place magnifying lenses and reducing lenses through the setting of the lens slot frame. The distance can be adjusted by watching through the magnifying lens and the reducing lens. The glasses are prevented from staying in a relatively fixed visual state for a long time, the visual fixation is relieved, and the effect of correcting and protecting the vision is finally achieved.
