[0002] Nowadays, more and more people are suffering from myopia, and the age of myopia is getting younger. Vision diseases bring great inconvenience to people's daily life. In order to improve vision, people have developed a lot of eye training equipment, and vision training devices such as flip mirrors are now available on the market. When the flip mirror is in operation, the positive mirror and the negative mirror are repeatedly switched from superimposed to separated states, which can make the ciliary muscles of the viewer's eyes contract and relax in rotation, so as to improve the adjustment speed, increase the adjustment range, increase the reading speed, improve the visual clarity, make the eyes more comfortable, and effectively prevent the occurrence and development of myopia, decreased visual function and visual fatigue caused by delayed adjustment and insufficient adjustment function.

[0003] The shielding piece is a structure used in a flip mirror or other vision training device to cover one eye so as to realize monocular training. However, the shielding piece in the existing flip mirror is fixed on the housing of the flip mirror. If the shielding piece is damaged, the flip mirror will not have the function of covering one eye, so that the flip mirror cannot be used for training.

[0004] For another example, patent application No. 202223006299.0 discloses a pair of reverse-scanning glasses that are easy to remove a shielding sheet, comprising a shell and a shielding sheet, wherein a vision training area is provided on the shell, and at least one lens outlet is provided at the bottom of the shell, and the vision training area is located outside the lens outlet; a first lens mechanism is provided in the shell, and the first lens mechanism comprises a first lens, a first lens mounting seat and a first transmission assembly, the first transmission assembly is connected to the top of the inner wall of the shell and is opposite to the position of the lens outlet, the first lens mounting seat is connected to the first transmission assembly, and the first lens is mounted on the first lens mounting seat; a female connecting portion is provided at the bottom of the shell, and a sub-connecting portion is provided on the shielding sheet; the female connecting portion is connected to the sub-connecting portion, so that the shielding sheet is installed below the shell and located in the vision training area; the sub-connecting portion comprises a first magnet; the female connecting portion comprises a second magnet provided at the bottom of the shell; the first magnet and the second magnet attract each other, so that the shielding sheet is installed below the shell and located in the vision training area. The flip mirror can solve the problem that the flip mirror cannot be used due to damage to the shielding sheet, but it has a complex structure and is inconvenient to use. Utility Model Content
