人眼能看清远近不同距离的物体,是需要进行屈光调节的。我们发现,调节的方式不是通过晶体变形来实现,而是通过晶体移位来实现:看速时晶体向前移位,看近时晶体向后移位——晶体移位说。但这不是屈光调节机制的全部内容,屈光调节机制还包括:视速共轭调节(视角调节)和视近共轭调节(焦距调节)的作用——二元调节论。晶体移位说和二元调节论,构成了眼屈光调节机制的全部内容。用这个调节理论,可以重新认识屈光状态的定义,修正晶体变形说的偏见,并且对青少年近视的成因与老视现象等做了全新的解释。
The human eye can see distant objects at different distances, is the need for refractive adjustment. We found that the mode of adjustment is not realized by crystal deformation but by crystal shift: the crystal shifts forward when it is seen, and the crystal shifts backward when it is seen - the crystal shifts. However, this is not the full content of the refractive adjustment mechanism. The refractive adjustment mechanism also includes the effects of apparent conjugate adjustment (viewing angle adjustment) and near-conjugation adjustment (focal length adjustment) - binary adjustment theory. Crystal shift said and binary adjustment theory, constitute the eye refractive adjustment mechanism of the entire content. With this theory of adjustment, we can re-understand the definition of refractive status, modify the prejudice of crystal deformation, and explain the causes of juvenile myopia and presbyopia.
