An estimated 1.5 billion people were affected in 2010. Myopia is the most common cause of permanent visual impairment and is expected to increase by nearly 5 billion by 2050. Based on the peripheral refractive theory, this study designed a contact lens that can change the peripheral refraction of the retina,and established a measurement system that can measure the refractive state of the eyeball. The ASAP optical simulation software was used to analyze the retina under different refractive conditions. The image, together with the optimization, calculates the refractive power vector as the basis for correcting the effect. The purpose of this study is to cause relative myopia or peripheral hyperopia to control the growth of the axial growth of the eye to control the development of myopia. According to the results, the fourth-order spherical aberration peripheral refractive lens model constructed in this study is used, which has a good corrective effect on myopia control.
