[0002] Myopia is divided into mild, moderate and high according to the degree. The degree less than 300 degrees is mild myopia, 300-600 degrees is moderate myopia, and more than 600 degrees is high myopia. Once developed into high myopia, the eye structure will change irreversibly, greatly increasing the incidence of eye diseases such as glaucoma, retinal detachment, and eye bleeding, which can cause vision loss. High myopia can also cause changes in the anterior segment microstructure, such as deepening of the anterior chamber, changes in the angle microstructure, changes in the lens nucleus and zonular suspensory ligament, which can lead to early onset of nuclear cataract, increased risk of cataract surgery, and increased risk of glaucoma. In addition, many eye fundus lesions and damage induced by high myopia are irreversible, which needs special attention. If it is already high myopia, in addition to regular vision tests, regular eye health checks, especially eye fundus, are needed. Myopia has become a national disease in China, affecting population quality and national security, and urgent intervention and control are needed. The traditional way is to wear myopia prevention and control lenses, but myopia prevention and control lenses have high production costs and are not easy to replace and maintain, which cannot meet the needs of users.
