The fundamental treatment of myopia or amblyopia is based on the physiology of the eye. Accommodation of the eye is achieved by the ciliary muscle, also known as the ciliary ligament (ciliary muscle), which connects the lens to change the projection and depression. The ciliary body muscle fiber bundles, located within the anterior intrascleral and suprachoroidal spaces, are the main components of the ciliary body and are the smooth muscles. In the brownish black layer of the sclera, the anterior portion is attached to the scleral spur and the lateral surface of the posterior portion is in communication with the scleral lining by means of a plurality of platelets. The sagittal section is a right triangle with the hypotenuse parallel to the sclera, the right angle inward toward the ciliary process, and the apex pointing toward the choroid, corresponding to the apex of the entire ciliary body. Ciliary muscle is composed of three fibers, and the outside is meridian fibers arranged in front and back; the medial is a ring-like fiber parallel to the limbus; radial fibers are obliquely arranged between the radial fibers and the annular fibers and are fan-shaped. These muscle fibers respectively have special physiological functions again, and the collection of eyes is accomplished through cohesion and abduction by six extraocular muscles, and when the people looked near for a long time, ciliary muscle makes the crystalline lens become protruding through the zonules, and the fatigue and production spasm just can be tired in a long time for the crystalline lens also can not recover when seeing the distance, along with the promotion to the healthy degree of concern of oneself, people just carried out eyesight training eyes through the mode of removal lens, thereby help oneself to resume eyesight.
