How Vision Works: Our Sense of Sight Ask A Biologist

The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina). Thus people interested in perception have long struggled to explain what visual processing does to create what is actually seen. There were two major ancient Greek schools, providing a primitive explanation of how vision works. http://www.cjig.cn/html/jig/2024/3/20240305.htm
