2、视觉效果与影响 视觉

　　What is vision?

　　Vision is the perception ability formed by light stimulating the visual organs and processed by the nervous system, which enables organisms to identify the size, color, shape and other characteristics of objects. More than 80% of the external information of human beings is obtained through vision.

　　Next, let's talk about the definition and core mechanism of vision. First, vision is formed by organisms receiving external light stimulation through the eyes, converting it into nerve signals through retinal photoreceptor cells, and then transmitting it to the visual center of the brain.Comprehensive perception process. The core functions include high-quality sensitivity and light and shade.

　　The coordinated operation of physiological systems Optical Pathway: Light is refracted through the cornea, aqueous humor, lens, and vitreous body, and finally focused on the retina. 4。 5 Signal conversion process:. The rods in the retina are responsible for low-light perception, while the cones are responsible for color vision and high-resolution imaging. 5。 Photoreceptor cells convert light energy into bioelectrical signals, which are transmitted to the visual center of the occipital lobe of the brain through the optic nerve. 6 Information processing level:Thee brain processes the signal cognitively, combining memory and experience to complete object recognition and spatial location. 7 Functional significance and biological value Advantages of information acquisition: Vision accounts for 80% -95% of human perception of external information, far exceeding other senses such as hearing and touch. 1。 6 Survival adaptability: It helps organisms avoid danger and locate resources by identifying moving objects, judging distance and color differences. 3 Cognitive expansibility: The combination of visual information with advanced neural activities such as language and thinking constitutes the basis of human learning, creation and cultural inheritance. 。
