How does cross-eyedness come about? Can it bring wealth?

Some faces make people look wealthy at first glance, while others make people feel particularly vulgar at first glance. Although many people say that you should not judge a person by his appearance, we have to admit that we do classify and judge others based on their appearance. Next, let’s go to the physiognomy column to see how cross-eyes are formed and whether it means wealth and prosperity.

How does cross-eyes form?

1. Congenital abnormalities

This type of strabismus is mostly caused by congenital abnormal development of the position 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 the use of forceps during delivery, which causes damage to the baby's head and face, or the mother's excessive force during delivery, which causes increased intracranial pressure on the fetus and produces punctate hemorrhages in the brain. The bleeding happens to be in the nerve nucleus that controls eye movement, causing paralysis of the extraocular muscles.

2. Imperfect development

Children, 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. Like the visual function, this function is established by repeatedly receiving clear images of external objects 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.

3. The characteristics of eyeball development make children susceptible to strabismus

Because children have small eyeballs and short eye axes, most of them are farsighted. Also, because children's cornea and lens have strong refractive power and ciliary muscle contraction force, they have 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.

4. Insufficient control of the eye movement center

If convergence is too strong or abduction is insufficient, or both exist at the same time, esotropia occurs; conversely, if abduction is too strong, convergence is insufficient, or both exist at the same time, exotropia occurs.

Can cross-eyed people get rich?

Not destined to be rich: Cross-eyed means that the black part of a person's eyes is when the two eyes are close together and staring at the bridge of the nose. If a person can make his face become cross-eyed without deliberately trying, then this person's personality and fortune are basically not very good. Even in terms of temperament, this kind of person is rather vulgar.
