What color are the eyes of the Chinese

Brown. Chinese generally have dark brown eyes. It's just that sometimes the dark brown eyes look black. The Chinese are brown. Asians only have brown eyes, and of course brown eyes can be light brown and dark brown. Mixed-race Chinese are exceptional.

In fact, when we talk about different eye colors, we actually mean that the front and middle part of the eye is different in color, which is composed of the cornea, iris and pupil. Since the cornea is colorless and transparent, the color of the eye is the color of the iris. The iris of the human eye is made up of five layers of tissue:

Endothelial cell layer, anterior bounding membrane, stromal layer, posterior bounding membrane, and posterior epithelial layer.

The eyes of the Chinese are black and brown. It is the pigment of the iris that determines the color of the eye. Westerners have less pigment in their irises.

Blue eyes are caused by very little pigment in the iris. The iris of our human eye is made up of five layers of tissue. They are the endothelial cell layer, the anterior bounding membrane, the stromal layer, the posterior bounding membrane, and the posterior epithelial layer.

In these five layers of tissue, the stromal layer, the anterior bounding membrane, and the posterior epithelial layer contain many pigment cells, and the amount of pigment contained in these cells determines the color of the iris.

A brief introduction to glasses

The eye is the most important organ of the human senses, and about 80% of the knowledge in the brain is acquired through the eye. Some things such as reading and reading, reading and appreciating pictures, looking at people, and enjoying beautiful scenery all need to use the eyes. The eye can distinguish between different colors and the brightness of light, and convert this information into nerve signals that are transmitted to the brain.

The human eye is the benchmark for the magnification of the telescope, that is, the magnification is 1, and the aperture is the size of the pupil of the human eye, which changes with the change of light intensity, generally fluctuating between 2 and 7 mm.

The eye changes the focal length of the lens by adjusting the degree of curvature (refraction) of the lens to obtain an inverted, reduced image. The farthest point that the eye can see is called the adjusted far point, and the far point that the eye can see is at a very far distance; The closest point that the eye can see is called the accommodative near point, and the distance between the two points is called the accommodative range. The near point of the normal eye is about 10 cm from the eye.

Chinese eye color is brown. Pupil is a hole formed in the iris tissue in the eye, the color of the iris of normal Asians or Chinese is dark brown state, usually look at other people's eyes to see the black eye kernel inside is brown state, the light entering the eye needs to enter the fundus through the pupil, and finally converge to the retina to be able to see things clearly.

Eye color varietyThe color of the eye, which actually shows the color of the iris, is brown, blue, and green, and the other colors are a mixture of these colors. The iris contains a large amount of pigment, the more pigment content, the darker the iris color, the less pigment content, the lighter the iris color, and the difference in pigment cells is related to race and ** color. The iris of East Asians is mostly dark brown, the iris of Western Europeans is mostly blue, and the iris of Northern Europeans can see green iris, and iris colors such as light gray and light gold are relatively rare.

Don't say it, Chinese are all brown eyes, different shades, and the depth looks like black.

Most Chinese have brown eyes, and a small number have black eyes.

The human eye is approximately spherical in shape and is located in the orbit. The average anteroposterior diameter of a normal adult is 24 mm, and the average vertical diameter is 23 mm. The anterior end protrudes 12 14 mm outside the orbit and is protected by the eyelids.

The eyeball includes tissues such as the wall of the eyeball, the intraocular cavity and contents, nerves, and blood vessels.

If the eye is compared to a camera, the cornea is the lens of the camera, and the eyelids and tears are devices that protect the "lens". When we are unconscious, the eyelids blink, and with each blink, there are tears that cover the surface of the cornea with a thin tear film to protect the "lens".

Since the cornea of the eye is clear, there are no blood vessels on it. Therefore, the cornea mainly gets nutrients from tears, and if the nutrients contained in tears are not sufficient, the cornea will become dry and the transparency will be reduced. The cornea also gets oxygen from the air, so many people feel a little dry after waking up.

Brown or black eyes.

Yellow people have white or olive skin color, and most have black hair, and a few have brown hair. They have brown or black eyes, but a few are blonde. Black hair, moderate beard and body hair, and a light body odor.

The chin is not protruding, but some people are pointed, while others are flattened. The bridge of the nose is of medium height and the nasal tip index is medium. The eye is medium-fissure, brown iris, the upper eyelid fold is well developed, and most eyes have an epicanthal fold covering the lacrimal mons.

The spade-shaped structure of the tongue surface of the upper incisors is also one of the distinguishing features of the yellow race.
