Description
Technical Field
The invention belongs to the field of vision correction and health care, and particularly relates to an intelligent control ciliary muscle training instrument suitable for teenager vision correction.
Background
The ciliary muscle is composed of smooth muscle fiber bundles and is divided into three parts: the outermost layer is longitudinal fiber in front and back direction, the middle is radial fiber in oblique arrangement, and the front and inner sides are annular fiber parts, also called muller muscles. There are two directions of force acting on the ciliary muscle contraction: a force causing anterior and medial movement of the zonules, primarily as a result of annular fiber contraction; another force pulls the anterior choroid forward, as a result of contraction of the longitudinal fibers. The anterior force makes the zonules loose, the crystalline lens become convex, and the diopter is increased, so that the accommodation function of the crystalline lens is embodied, and the short-distance objects can be seen clearly; the latter force moves the anterior portion of the choroid anteriorly while pulling the sclera medially. When we want to focus something at a distance, the ciliary muscle will relax naturally, and the ligament that positions the lens will be tensioned, so that the lens will become flat and thin. The focusing ability of the crystal is reduced, which helps us to watch the east and west in a long distance. When looking at the near, the ciliary muscle contracts and the lens thickens.
The myopia degree of teenagers in the growth and development period can be continuously increased along with the growth and development and incorrect eye using habit, the axis of the eye can be continuously elongated, and the intraocular pressure can be increased.
