 The human eye is one of the most important sense organs. Most people feel is their feeling of discomfort or organ disease. Human visual organs, including the eye, visual pathway and ancillary devices. Nearly spherical shape of the human eye, called the eye. Eye wall is surrounded by a layer of the eye tissue, the sclera, choroid and retinal components. Outside to inside wall of the eye can be divided into three layers: fiber membrane, pigment film, the retina. Fiber membrane by fibrous tissue composition, hard, tough and flexible, has a protective effect on the eye, and can maintain the shape of the eye, it seems like the egg shell. 
 Fiber membrane can be divided into the cornea, sclera, scleral margin. Membrane known as uveal pigment, eye tissue with nutrition and shading effect, from front to back can be divided into iris, ciliary body, choroid three parts. Iris middle of the pupil. Eye contents, including aqueous, lens and vitreous. These three parts with the outer layer of the cornea, the eye's refractive constitute the system. A colorless transparent aqueous liquid, full of the anterior chamber, posterior chamber, about 0.15 ~ 0.3ml, it has the nutrition and maintenance of intraocular pressure. Lens is located behind the iris, vitreous in front, with the suspensory ligaments and ciliary body associated with, is a flexible, transparent, semi-solid, Xingzhuang Si double convex lens, is important refractive eye one. 
 Vitreous gel is a colorless and transparent body cavity behind the lens in full, with refraction, the role of the fixed retina. Vitreous and aqueous lens, cornea, etc. together constitute the refractive eye and eye wall of the retina and play a supportive role, the retina and choroid, coherent picture. Trauma or surgery in the event of vitreous loss, it is easy to cause retinal detachment. As the name suggests is the eye fundus bottom, that is, the innermost eye tissue. 
 It includes the retina, optic nerve and central retinal vessels. If the eyes are disease, will have great visual impact. Manifested as decreased vision, visual distortion, discoloration, as small change. In addition to the human eye and eye wall of the eye contents, there are a number of appendages, which are the eyelids, conjunctiva, lacrimal apparatus, eye muscles and eyes. From the optical point of view, the eyes could be seen as two systems: the cornea and lens. The center of its surface, similar to the optical axis in a common axis. Usually cross the retina at the center axis of nasal fossa and a point slightly above the average angle of tilt in the horizontal direction is 4 to 5 degrees (a corner), slightly larger than the vertical direction of 1 degree tilt. 
 Head Pearl See "Chishui Xuan Zhu" Volume. Also known as eyes, eyes. The eye. The main part of the eye, somewhat similar to spherical, the central front in the eyes. The front-end for the black eyes, black eyes in the Huang Ren, Huang Ren middle of a round hole, the name Tong Shen. The edge of the black eye white eye immediately. There Shenshui head beads, eye beads, God cream, depending on the clothes and so on. Head, Department Head with Pearl back, and on into the brain, the main organ for the visual.
