为揭开学生近视产生机理，首先使动物形成近视，证明了其机理为代偿变化。因眼的功能为凸透镜成像，物距像题成反比，读写时物距小，像距增大，为成像于视网膜即自动调节（功能代偿），为节省调节眼球逐渐变长（结构代偿），变长后看近不用调节了，但看远不清了（近视了）。又因眼球变长总生理需要，所以多种疗法都是违反自然规律的，故均无理想结果．科学的防治办法是通过透镜组，把看近时入眼光线的几何特性变成看远的。
To uncover the mechanism of myopia students, first of all, the formation of myopia animals, proved its mechanism for compensatory change. Because the function of the eye is convex lens imaging, the object distance is inversely proportional to the title, when reading and writing, the object distance is small, the image distance increases, the image is adjusted automatically in the retina (function compensation) Reimbursement), do not have to adjust to see after the variable length, but look far unclear (myopia). Because of the longer total eyeball physiological needs, so a variety of therapies are against the laws of nature, so no ideal result. Scientific approach is through the lens group, to see when the near-eye light of the geometric characteristics of the look far.
