Abstract: More and more people are wearing glasses now. There are many hypotheses on the mechanisms of myopia genesis. At large, myopia is the momentum of human evolution. Along with the advances of science and productivity, the work style of mankind has changed from rough to increasingly refine and requires seeing at near for prolonged time. Moreover, training before work, i.e., education time has been prolonged. When reading and working at near, the imaging of the objects will fall behind the retina. Therefore, adjustment must be made to get the image onto the retina. There exist two approaches of adjustment. One is by the contraction of ciliaris to increase the curvature of the lens. The other one is the elongation of the axis of the eyes. The contraction of ciliaris is a short-term reaction, which we call adjustment; in contrary, the elongation of eye axis is a long-term adjustment, which we call adaptation. It is known that myopia is inheritable. Therefore, the increasing popularization of myopia is a type of Lamarckian evolution. In this paper, we discuss the genesis of myopia and the rationality of Darwinian and Lamarckian evolution.
