Working principle: the principle of fog vision therapy is that a myopic person wears a pair of front-view glasses when watching near objects such as doing lessons, reading and watching computers, so that eyes feel comfortable and natural like looking at distant scenes when watching near objects, and the burden of eyes is relieved. Moreover, eyes are not tired like before even if the user looks at near objects for a long time. Then, when the patient views the distant object, the negative mirror can be worn to allow the vision to regain clarity. When the eyes are used in a short distance, for example, when the eyes are used for reading and writing, the patient wears the +1.5D lens to see the characters clearly, the eyes are comfortable and do not feel dizziness as a standard, so that the burden of adjusting the eyes to see the near can be reduced, the adjusting force of the eyes is reduced, the eyes are not easy to fatigue, and the purpose of treating myopia is achieved.
