Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a myopia prevention and control phototherapy device with a light-shielding structure. Background Art

[0002] Currently, myopia prevention and control phototherapy devices are mostly used to effectively prevent and control myopia in adolescents and children. However, since the distance between each person's eyes and the degree of pupil light sensitivity are different, the existing phototherapy devices cannot be well adapted to everyone.

[0003] For example, a myopia and amblyopia therapeutic device (announcement number: CN216221979U) includes a therapeutic device and a base. The base is provided with a connecting column, and the top of the connecting column is provided with an angle adjustment mechanism. The therapeutic device is loaded and unloaded from the connecting column through the angle adjustment mechanism. The therapeutic device includes a shell and two phototherapy eyepieces installed therein, as well as a control circuit board and a power supply. The upper surface of the shell is embedded with control buttons and a display screen, and the lower surface is provided with a base. The phototherapy eyepiece includes a lens barrel, a lighting component is installed at the rear end of the lens barrel, and several lenses are provided on the inside. An eye mask is provided at the front end of the shell, and the eye mask is aligned with the front end of the lens barrel. The therapeutic device of this utility model can be installed on the connecting column and the angle can be adjusted, or it can be removed and carried with you, and placed on a desktop elsewhere for treatment. Compared with existing instruments for treating myopia, it has good treatment effect and is more convenient to use.

[0004] When in use, the device does not have the ability to adjust the distance between the two sets of lens barrels, which makes it easy for teenagers to not be able to completely fit their eyes on the two sets of eye masks during treatment, which can easily cause light leakage. Moreover, since the degree of brightness of each person's pupil is different, this will affect the treatment effect. Therefore, we need to propose a myopia prevention and control phototherapy device with a light-shielding structure. Utility Model Content
