Description

Technical Field

[0001] The utility model relates to the technical field, in particular to the technical field of flip mirrors. Background Art

[0002] With the frequent use of video equipment, the number of myopic eyes is also increasing. Especially for adolescents and children, during the critical period of growth and development, long-term close-range use of the eyes leads to eye fatigue and abnormal accommodation function, which increases the risk of myopia. Medically, we evaluate the state of eye accommodation function by accommodation amplitude and accommodation sensitivity. Among them, the flip mirror that improves the eye accommodation convergence function is one of the simplest and most effective devices. When the flip mirror is flipped, the positive mirror and the negative mirror are exchanged, which can make the viewer's eyes produce an alternation of accommodation and relaxation, so as to improve the accommodation speed, increase the accommodation amplitude, increase the reading speed, improve the visual clarity, make the eyes more comfortable, and effectively prevent the occurrence and development of myopia caused by accommodation lag and insufficient accommodation function, as well as symptoms such as decreased visual function and visual fatigue.

[0003] For example, the Chinese utility model patent with the publication number CN212913793U proposes a device for detecting and improving the function of eye accommodation and convergence, which relates to the field of intelligent wearable devices; it includes a tightening belt and a fixedly connected front cover and rear cover, the two ends of the rear cover are fixedly connected to the two ends of the tightening belt, and the tightening belt is elastic; the bottom of the rear cover is fixedly connected to a rear mirror, the front end of the rear mirror is provided with a flip mirror, the top of the flip mirror is connected to a flip mechanism, the flip mechanism is fixedly arranged on the front cover, the flip mechanism is respectively connected to a battery and a circuit board, the circuit board and the battery are respectively fixedly installed on the front cover, the circuit board is connected to a switch button, the switch button is arranged above the front cover, and the circuit board wireless signal is connected to a control terminal. However, the problem with this structure is that only the flip mirror can move, and the rear mirror cannot move. When in use, the rear mirror always remains in front of the user's eyes, resulting in limited training methods and failure to meet a variety of training methods. Summary of the invention
