It is about a management method.

In general, myopia is a disease of the eye caused by a weakening of the control function, which means that the focus of light incident through the lens in the eye does not form at the center of the retina, but at the front. Therefore, conventionally, a method of correcting by wearing glasses is used, but the use of glasses has an effect of temporarily slowing the progression of myopia, but as a result, vision deterioration increases with longer use of glasses, which leads to blindness.

In general, eyes have the following properties:

The lens is thicker when looking at near objects and thinner when looking at distant objects. In other words, the lens is elastic and has ciliary muscles (inner muscles) around it, so that when this muscle is caught outside (ie, the contraction of the ciliary muscles), the lens becomes thinner and the distant is well visible, on the contrary, when the muscle is slowed (ie (A phenomenon that the ciliary muscles are stretched).

It is known that the extraocular muscles (upper quadrant, inferior rectus, inferior rectus muscles, four rectus muscles of the superior rectus muscle, the superior oblique muscle and the inferior oblique muscle) are also involved in the regulation of the eye.

In other words, the four rectus muscles are contracted when looking in the distance, and the short axis of the eyeball becomes shorter, and the diameter is longer, which helps the inner muscles tend to be pulled out. At the same time, the diameter is shortened, which helps the shape roots to be slowed down.

Myopia is weaker than that of the normal and the quadriceps, which are the internal muscles and the four rectus muscles and the two quadriceps, and it is clinically confirmed that regular myopic movements are effective in preventing myopia and treating myopia. .
