What is the cause of cross eyed? What does cross eyed mean

。。In fact, he just wanted to distract the fried noodles so that he could take the opportunity to sneak up on the fried noodles. You can go and watch the clip twice, after the cross-eyed, Huang Zongze was stunned and then was attacked.

Cross-eyed refers to the fact that the pupil in the middle of the eye is naturally or artificially close to the middle, and it looks like two chickens fighting, so it is called cross-eye, also called the opposite eye.

The eyes of a normal person look at the same object, and the object is imaged at the retina of the two eyes, and overlaps in the optic center of the brain to become a complete single object with a three-dimensional sense, this function is called binocular monovision.

However, in the process of binocular monovision, infants and young children are easily affected by external factors, resulting in one eye fixing on the target, and the other eye is deviated and cannot look at the same target, so strabismus occurs. In medicine, the inward squint of the eyeball when looking at an object is called esotropia, which is commonly known as "cross-eyed".

It starts with the muscles and nerves that are responsible for eye movements. There are six extraocular muscles on the outside of the eyeball, and normally, when people look at something, the movement of the eyes is parallel and consistent, no matter which direction it is in.

Since the contraction of the muscles is carried out under the regulation of the nerves, both eyes of the target on the right are turned to the right, and both eyes of the target on the left are turned to the left, and the phenomenon of the right eye to the right and the left eye not to the right will not occur.

If the child's two eyes are not developed, one eye is normal and the other eye is highly myopic or astigmatism; or the distance between the two brigade attendants is too far apart; Or children like to play with small toys and often play games in weak light conditions since childhood, resulting in eye muscle balance disorder, neuromuscular paralysis, so it is likely to clear the "cross-eyed".

Explanation of cross-eyed.

Esotropia is commonly known as esotropia. Wang Xiyan "Fu Yuan Lao and His Cow in a White Hat": "Especially the daughter-in-law in the front room is not decent, and she was born with a pair of cross-eyed. ”

Wei Shu Food Journal": "Looking for money that can't be done, the law has a clear style, referring to corns, ring chisels, and there is no restitution." "The Sixteenth Year of Emperor Wu of Liang":

Refers to corns.

I disagree with the answer adopted by the questioner.

The questioner adopted the answer that said, "There are a lot of gadgets hanging on the swaddling clothes, and if there is a thing hanging within the range of one meter and a half, there is always such a thing, and the child will keep looking at it, and finally it will become habitual and become cross-eyed." "In fact, the consequence is that the child's eyes are oriented to the near and close, and over time, it is easy to evolve into myopia, rather than cross-eyed.

Cross-eyed refers to esotropia, the formation of esotropia is related to the extraocular muscles, which is related to the refractive state of the eyeball.

The uncoordinated development of extraocular muscles causes more esotropia, and this part of the population should be considered congenital.

There are also a subset of cross-eyed patients who have normal extraocular muscle development, but their refractive status is congenital hyperopia. In order to see clearly, the ciliary muscle drives the lens to adjust to achieve the purpose of clear vision, and the adjustment drives the gathering function to cause the eye to turn inward, thus forming cross-eyed. This segment of the population with inward slope accounts for a larger proportion.

However, these people can make their eyes in a normal position and no longer cross-eyed by accurate refraction, wearing appropriate glasses, and allowing the eyes to stop using accommodative sets when seeing. This part of the population should also be counted as congenital.

To put it simply, it means that the eye position of this part of the person is actually normal, but the bridge of the nose is wider and covers part of the inner eyeball, making the eyeball look not centered, giving people the feeling as if it is slanted inward, in fact, the eyeball is still in the right position. This part of the population is called pseudoesotropia.

There are not many people who have true acquired esotropia, and it is generally related to trauma.

Some are innate, and acquired are generally formed by visual attention, generally looking at an object for a long time.

In fact, many people's cross-eyed fighting is related to the ignorance of their parents. Many children lie in the swaddling clothes, and there are a lot of gadgets hanging on the swaddling clothes, if there is a range of less than one meter and five, there has always been such a thing, and the children have been looking at it all the time, and finally it is habitual, and it has become cross-eyed.

So if parents give a little child something, either make the distance a little farther away, let him see a little farther, or you let this thing move around, don't have a fixed thing to attract his attention at a close distance of one meter and a half when the child's eyes are still very unformed and his eyeballs have not yet formed.
