My dad s eyes are 2 0, and my mother s eyes are 800 degrees, will it inherit my myopia?

Some people are short-sighted, and so are their parents; Some parents are not short-sighted, but they wear myopic glasses. When choosing a spouse, some people are also worried about whether their lover is short-sighted and will affect their children. This is the question of whether myopia can be hereditary.

This starts with the type of myopia. Myopia can be divided into two types, namely high myopia and common myopia. Common myopia, also known as simple myopia, can occur from childhood, to the age of 20 that is rarely progressed, after wearing glasses vision can be corrected to normal, myopia is generally below 600 degrees.

High myopia, also known as progressive myopia, is another eye disease completely different from simple myopia, with the increase of age, the anterior and posterior axis of the eye continues to lengthen, the back of the eye expands, accompanied by degenerative changes in the veinal retina of the fundus, and the vision is difficult to correct to normal after wearing glasses, and the vision gradually decreases, so that serious disorders occur.

According to the results of the investigation of eye diseases, the incidence of myopia in family members with a family history of myopia is higher than that of those without a family history of myopia, indicating that the incidence of myopia is related to heredity. However, the occurrence of myopia is affected by acquired environmental factors, so at present, scholars believe that myopia belongs to polygenic inheritance, that is, patients have multiple pathogenic genes, but there are environmental factors, which is a phenomenon that is easy to see in the occurrence of simple myopia. Environmental factors include poor lighting, poor reading and work habits, such as long hours of reading and close work, and a constant state of tension and contraction of the regulatory muscles of the eye, which in turn weakens the ability to accommodate, resulting in myopia.

But under the same conditions, not all people develop myopia, and some people with myopia do not do near work or rarely read books and newspapers. It can be seen that myopia is the result of a combination of genetics and environment.

For high myopia, it is thought to be caused by autosomal recessive inheritance. That is, both parents are highly myopic (note: this refers to high myopia!).

The incidence of high myopia in the children of patients is 100%, and if one parent is highly myopic and the other is a gene carrier (no myopia), the expected incidence of high myopia in the child is 50%; If neither partner has high myopia but is only a gene carrier, the incidence of high myopia in the child is 25%.

You have a very serious bulge under your eye, which is due to long-term glasses.

To maintain the prescription, you must develop good eye habits. Don't let your glasses get tired.

There is a tendency to do this, but it is not serious, so you should pay attention to calcium supplementation. I'm typing too slowly, so I don't write the principle.

Nowadays, the inheritance of myopia covers almost all inheritance patterns, but most of the simple myopia is polygenic inheritance. That is to say, the environment plays a very important role in it, so simple myopia is also called "school myopia", which is mainly caused by environmental stress. Genetically related myopia is often high myopia, and there are some myopia with obvious complications and other complications, which are called genetically related myopia.

So far, population genetics studies have found that as long as one of the parents is myopic, the probability of a child developing myopia is twice higher than that of both parents who are not myopic. If both parents are nearsighted, it is higher than in a family where both parents are not myopia, up to a number of times. Surveys have been conducted in this group, such as in primary schools, and the prevalence of myopia in children at the age of 7 is 7.0% if both parents are not nearsighted.

However, as long as one party has myopia, it is as high as 26.0%.

Parents are highly myopic, children will have a strong genetic tendency, should be changed from an early age to pay attention to the development of good eye habits, if necessary, with targeted ** to prevent and protect, the method of binocular synchronization eye muscle** has a relative advantage, may wish to do relevant understanding.

It is not congenital myopia, which means that children are also prone to myopia, and it may not occur if it is prevented well.

Myopia in children is the result of a combination of genetics and acquired factors, and children whose parents are myopic do not necessarily have myopia. Therefore, regardless of whether the parents are myopic or not, the child should take precautions to prevent myopia.

Not necessarily, if the parents are born, it may be, and it may be passed on from generation to generation!

Analysis: The relationship between myopia and heredity:

Genetic factors play an important role in the occurrence and progression of myopia. Some people have done a large number of family statistics, also known as family surveys, where both parents have myopia, the percentage of their children with myopia is significantly higher than that of other families. If one parent has myopia, the myopia rate of children is in the middle.

Children whose parents do not have myopia have the lowest incidence rate. In addition, the incidence of myopia in yellow people is the highest in the world, and the incidence of myopia in Southeast Asia, including China, is more than 40%, and the white race is medium, while the black and Eskimo people have very little myopia, which shows the genetic role of the species. Chinese experts have conducted twin surveys, twins suffer from myopia at the same time or do not suffer from myopia at the same time, that is, the consistency rate, the results show that the twin agreement rate (myopia) is higher than that of non-twins.

Among twins, the myopia concordance rate of identical twins is higher than that of fraternal twins, which also indicates that myopia is a hereditary disease. Experts have also calculated that genetic factors account for 65% of the causes of myopia through formulas.

On the other hand, myopia is not completely determined by heredity, parents have myopia and not all children have myopia, and those with myopia genetic factors do not manifest or are not explicit, and myopia does not develop at this time. There are some congenital myopia, and they tend to have a higher degree, but fortunately only a very small number of myopia eyes. This type of myopia has a family history and is genetically determined.

Strabismus**:

1. Imperfect development: the monovision function of both eyes is not perfectly developed, and the extraocular muscles cannot be well coordinated, and external unstable factors (fever, fright, etc.) can promote the occurrence of strabismus.

2. Congenital anomalies: abnormal position of extraocular muscles, which can also cause punctate hemorrhage in the brain during childbirth, paralyzing extraocular muscles.

3. Characteristics of eye development: children's eyeballs are small, the eye axis is short, and most of them are farsighted. In addition, due to the strong contractility of the ciliary muscle of the corneal lens in children, the adjustment force needs to be more inward, and excessive radiation beating can easily lead to invertosis.

Is there a genetic relationship between strabismus?

Is there a genetic relationship between strabismus? This is a concern for all strabismus patients or parents. The conclusion drawn from clinical observation and applied twin genetic studies is yes – strabismus is hereditary.

As early as 1952, it was reported abroad that 158 cases of strabismus had a positive family history). In recent years, domestic and foreign scholars have used the twin method to study the results of the heritability of common exotropia are more than 70%, and the heritability of common exotropia has been reported in China. A group of strabismus families reported that 8 people in 4 generations suffered from the same extraocular myopathy, called congenital extraocular generalized fibrosis syndrome, and there were patients in each generation, which was chromosomally dominant.

Children with this disease marry normal people, and their offspring do not suffer from this disease. The clinical manifestations are that the upper eyelids cannot be raised, and the eyes need to be looked up, and the eyeballs are fixed in a certain position and cannot be rotated in any direction. It can be seen that strabismus has a certain hereditary nature, but not all strabismus is inherited.

It is now agreed that common strabismus has a multifactorial inherited characteristic.

Hello, your myopia is relatively high, and this condition is likely to be passed on to the next generation. To prevent this from happening, you should pay attention to conditioning from the time your wife is pregnant, supplement more vitamins, eat more tomatoes, carrots, pork liver and other foods, which will help. After the birth of the child, it is also necessary to pay attention to vitamin supplementation

Generally speaking, myopia is not inherited, but children in families with myopia are more likely to be myopic. Because children look like adults, whose children look like whom, right? The second is to live in a family, and the habits and diet are the same.

Hello, if it is acquired myopia, it will generally not be passed on to offspring, and there are two reasons for myopia: one is improper use of eyes, not paying attention to eye hygiene, and not being well corrected in the process of developing myopia**, resulting in eye myopia, which is more common in ordinary myopia (myopia below 600 degrees). Another reason is related to genetics, which is mainly manifested in high myopia (high myopia refers to myopia over 600 degrees), for which heredity is an important factor.

In general, myopia is acquired, and there are no research reports at home and abroad that clearly point out that myopia will be inherited, but there is a genetic tendency, myopia inheritance is mainly the inheritance of high myopia, and the appearance of myopia is also very related to the development of children or some nutritional deficiencies in the fetus and infants.

Myopia can be inherited, and if both parents are highly myopic, the possibility of inheritance is greater.

Myopia can generally be divided into pathological myopia and simple myopia, pathological myopia refers to myopia with high degree and other conditions, with genetic heterogeneity, the common is autosomal recessive inheritance. Simple myopia is related to both genetics and environment, and belongs to multifactorial inheritance.

Research data show that the probability of myopia is high in the inheritance of high myopia, and the probability of myopia of parents above 400 degrees is 70% for the mother and 50% for the father.

Now myopia is getting younger and younger, and many children start myopia at a very young age. This is partly due to genetic factors, but also partly due to inattention. Generally, children under the age of 18 are nearsighted, whether they are born or acquired, and they should take medication in time to control the deepening of their vision.

It is recommended to take Leyan Vision Nutrients, twice a day, one pack each time, with warm water, generally insist on taking it for a period of time, and the child's myopia can be controlled or even improved.

Will parents with high myopia be passed on to the next generation?

First of all, does myopia last a lifetime? This problem should be treated in two situations, one is mild myopia and the other is deep myopia. Mild myopia is what we usually call pseudomyopia, which can be completely recovered on its own.

When I used to go to middle school, I had a physical examination of myopia of more than 300 degrees, and then I didn't go to **, but I paid special attention to eye hygiene and eye habits, and adjusted it myself, and then when I went to college, my eyesight recovered to about it. Therefore, pseudomyopia can be adjusted after acquisition and will not last for a lifetime.

But pseudomyopia is left unattended, once left to develop freelyIf you develop deep myopia, it will really follow you for a lifetime, and wearing glasses is not only unsightly, but also has an impact on your life. Of course, if it is deep myopia, don't give up on yourself, we can maintain this level as much as possible, don't let the myopia continue to worsen, if you take good care, it is also possible to take off your glasses.

Secondly, Will 800 degrees be passed on to children? The answer is yes, myopia is mainly affected by genetic factors and external factors. Therefore, whether a child is myopic or not has a lot to do with his parents, that is to say, the more severe the myopia of the parents, the greater the chance that the child will be inherited.

According to incomplete statistics, if both parents are myopic, the probability of their children being myopic in the future is higher than that of children of other departments. Of course, myopia is also affected by external factors, so we also need to teach children good eye habits.

Therefore, for the sake of ourselves and our future children, we must protect our eyes.

It lasts a lifetime and is likely to be passed on to children.

Myopia is hereditary, from the degree of myopia, myopia is divided into mild, moderate and severe, mild is below 300 degrees, moderate is 300-600 degrees, severe is more than 600 degrees.

In terms of hereditary probability, the higher the degree, the greater the hereditary probability. For example, if one of the parents of a child has myopia, but the myopia is mild, the chance of the child developing myopia in the future is very small or none. However, if one of the parents is myopic above 600 degrees, that is, high myopia, the chance of the child developing myopia in the future is much greater than that of a child whose parents are not myopia.

If both parents are myopic and both are highly myopic, the child will have a greater chance of developing myopia, and there is no quantitative way to measure the chances of how much there is or how hereditary it is.

There are many factors, both parents have myopia is one aspect, and it is also related to the child's acquired study, life and work habits.

If you have myopia, as long as it lasts for more than half a year, you will be diagnosed with true myopia, and it will last for a lifetime.

From the perspective of chromosomal genes, "some studies have shown that the occurrence of high myopia in China is autosomal recessive inheritance, that is, both parents are highly myopic, and the probability of children suffering from high myopia is greater; If one parent is highly myopic, 50% of children are highly myopia" – although this understanding has yet to be confirmed, it at least shows that the child's myopia is closely related to both parents.

In addition, there is the migration of living habits - because the father reads a lot, the son reads a lot, because the father is a computer operator, the child often goes online; Because both parents are intellectuals, children study very hard and other habits are very contagious
