Description

[Technical field]

[0001] The present invention relates to the technical field of vision corrector products, and in particular to a vision reversal racket with reasonable structural design, outstanding application effect and flexible height adjustment. [Background Technology]

[0002] The vision correction reversing racket product in the vision corrector is also called a flip racket or a butterfly racket. In terms of specific structural components, it is generally composed of two pairs of positive and negative prisms with equal degrees and a handle. In actual use, a vision card is placed in front of the trainee, and the reversing racket is placed between the trainee's eyes and the vision card. The positive and negative pairs of prisms on the reversing racket are flipped back and forth by using the handle, and the number of changes from positive mirror degree to negative mirror degree within one minute is recorded while ensuring that the trainee's eyes can read clearly during each flip.

[0003] With the development of science and technology, the popularity of televisions and computers and the lack of sufficient outdoor sports, the eyes are kept in a close-range visual state for a long time, without effective and sufficient pupil adjustment of near and far distances. In particular, excessive study pressure also causes the myopia rate of students to increase year by year. Under such circumstances, the reverse shooting product of vision corrector came into being.

[0004] Compared with existing vision correction instruments, the flip-shot product can adjust the distance between far and near, thereby achieving the purpose of correcting and protecting vision by adjusting the visual state.

[0005] However, existing flip-up products still have some shortcomings, such as the positive and negative lenses are all open-type, which can easily cause interference to users during actual use, affect the accuracy of correction, and are not conducive to long-term handheld use.

[0006] For example, the Chinese patent with the patent number of 202320847379.4 and the patent name of "A Vision Corrector" discloses the following content: A vision corrector, comprising: a shell, a slide groove is provided on the surface of the shell, and a toggle block is slidably connected inside the slide groove; a panel, the panel is rotatably connected to one end of the shell, and a lens groove frame for placing magnifying lenses and reducing lenses is embedded inside the panel, and the lens groove frame is used to clamp and place magnifying lenses and reducing lenses, and the shell is internally provided with a movable part connecting the panel with the toggle block, and the toggle block is slid up and down in the slide groove to drive the panel to rotate through the movable part, and the panel can rotate at an angle of 45 degrees. The vision corrector can place magnifying lenses and reducing lenses through the setting of the lens groove frame, and adjust the viewing distance by using the magnifying glass and reducing glass to avoid the glasses being in a relatively fixed visual state for a long time, relieve visual fixation, and ultimately achieve the effect of correcting and protecting vision.

[0007] The above-mentioned technical solutions of the prior art have the aforementioned problems. Based on this, further improvements and enhancements are needed in terms of structure and usage. [Summary of the invention]
