If it is said that humans have never seen light itself, no one may believe it, but it should be an indisputable fact. Because there is no light that can exist independently without the light source/charge, light is only one of the manifestations of the Coulomb force and magnetic force interaction between charges, and of course it cannot be seen. What people see in daily life is the luminous body → the charged particle group vibrating at the frequency of visible light, and they interact with the charged particles on the retina in the human eye by Coulomb force and magnetic force, thus producing a corresponding electrochemical reaction After the corresponding information is generated and transmitted to the visual system of the brain, the talent has the vision of seeing the luminous body. This article starts some discussions on this, hoping to get corrections from interested friends.

如果说人类从未看到过光本身，可能不会有任何人相信，但这应该是不争的事实。因为根本不存在能脱离光源/电荷而独立存在的光，光只是电荷之间才存在的库仑力和磁力相互作用的表现形式之一，当然不可能被看到。人们日常所看到的是发光体→正在以可见光频率段的频率振动的带电粒子群体，它们与人眼中的视网膜上的带电粒子间进行着库仑力和磁力相互作用，从而产生了相应的电化反应并产生相应的信息传递到大脑视觉系统后，人才产生了看到了发光体的视觉。本文就此展开一些讨论，希望得到有兴趣的朋友们的斧正。
