Description

Sliding structure, lower jaw bracket and amblyopia and myopia comprehensive therapeutic instrument

Technical Field

The utility model relates to a sliding structure field, medical equipment field, amblyopia myopia therapeutic instrument field especially relate to a sliding structure, chin bracket and amblyopia myopia comprehensive therapy appearance.

Background

A large amount of research on student myopia and myopia animal models in domestic and abroad in nearly ten years suggests that the occurrence and development of acquired myopia of students mainly relate to a main cause: close to, and two key links: looking backward through focus and backward focusing (i.e., accommodative lag) are related. The professor of the Chinese original student myopia prevention and treatment expert group, the xuguang, also points out that the main cause of myopia development and development is 'seeing nearly' such as reading, writing and watching television and computer. When the human eyes see near, the central area is clear, but the peripheral vision is unclear, and the eyes are out of focus after the peripheral vision, so that the development of the axis of the eyes is lengthened, and the myopia is increased by about 300 degrees for every 1 mm. Meanwhile, the human eyes see near for a long time, which can cause the 'solidification' of the accommodation of the crystalline lens in the eyes to cause the post-focusing phenomenon of the accommodation lag, and can also cause the lengthening of the axis of the eyes and the development of myopia. Therefore, any myopia treatment needs to be capable of well controlling the near vision of students, or effectively blocking defocusing after the near vision of the periphery of the retina, or blocking focusing (adjustment lag) after the near vision of the retina, so that a good long-term effect can be obtained.
