I have a pair of cross-eyed eyes and am often laughed at. My friends don’t even want to play with me. All because of those damn eyes, my friends stay further and further away from me, making me more and more lonely and inferior. A person with cross-eyes is a villain. This is also the insult we often hear from others. What is cross-eyes? Why do I have cross-eyes? This is a question asked by a netizen. Now, let Ziweifu answer it and popularize the knowledge to everyone at the same time!
Children with imperfect development, especially infants and young children, have incomplete binocular vision function and cannot coordinate the extraocular muscles well. Any unstable factors can lead to the occurrence of strabismus. Human's monocular vision function is gradually developed after birth. Just like the visual function, this function is established by repeatedly receiving stimulation from clear external images, and gradually develops and matures. Infants only have gross fusion image 2 months after birth, and the establishment of precise fusion image function will continue until after 5 years old. Stereoscopic vision is established at the latest, and it is close to that of adults at 6 to 7 years old. Therefore, the period before the age of 5 when binocular single vision function is not yet perfect is a high incidence period of strabismus in children. Congenital abnormalities This type of strabismus is mostly caused by congenital abnormalities in the position and development of the extraocular muscles, abnormal development of the extraocular muscles themselves, incomplete differentiation of the mesoderm, poor separation of the eye muscles, abnormal muscle sheaths and fibrosis, and other anatomical defects or paralysis of the nerves that control the muscles. Some cases are due to head and facial injuries caused by the use of forceps during delivery, or the mother's excessive force during delivery, which leads to increased intracranial pressure in the fetus and causes punctate hemorrhage in the brain. The bleeding happens to be in the nerve nucleus that controls eye movement, causing paralysis of the extraocular muscles. In addition, there are also genetic factors. Strabismus is not inherited by all members of the family. This defect is often indirectly passed on to the next generation of children. Generally, strabismus that occurs within 6 months after birth is called congenital strabismus. It does not have the basic conditions for establishing binocular vision and has the greatest harm to the development of visual function. The characteristics of eye development make children susceptible to strabismus because their eyeballs are small, their eye axes are short, and most of them are farsighted. Also, their corneas and lenses have strong refractive power, and their ciliary muscles have strong contraction power, that is, strong accommodation power. Such children need more accommodation power to see objects clearly. At the same time, their eyes turn inward forcefully, resulting in excessive convergence, which can easily cause esotropia, a type of esotropia called accommodative esotropia. If the eye movement center's control ability is insufficient, if the convergence is too strong or the abduction is insufficient, or both exist at the same time, esotropia will occur; conversely, if the abduction is too strong, the convergence is insufficient, or both exist at the same time, exotropia will occur. Personality traits of people with cross-eyes <br />People born with cross-eyes are always against others, do not value cooperation, do not know how to be tolerant, try to follow their own temperament, and never take other people's feelings into consideration. Such people are narrow-minded, paranoid, easily excited, and love to fight with others. Such people often make enemies in life because they are calculative by nature, so they don't know how to give in and will even take the initiative to provoke others to satisfy their own desires. However, such behavior that disregards other people's feelings can easily lead to bad consequences, so it is best to stay away from such people. People with cross-eyes should be careful. If the cross-eyes are very severe, they may suddenly face financial difficulties in middle age. How to prevent cross-eyes in babies 1. After 2 months, the baby's vision improves and he can pay attention to people and objects around him. At this time, if the baby sleeps in a cradle, do not place toys or objects in the air near the cradle, especially do not place anything within 1.5 meters. 2. If you place toys or objects, make sure they are 1.5 meters away. But do not place just one. Place several at a distance so that the baby can move his eyes and look at the toys or objects in turn. 3. The baby should not sleep in the cradle for too long. The baby should be picked up and turned around from time to time so that the baby can see everything around him, which will make him curious and increase the frequency of eye movement. 4. The baby’s sleeping position must be correct and must not sleep on one side for a long time.
