Can genetic myopia be improved, and how much can it be improved?

Is myopia hereditary?

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%.

Many parents with myopia tend to worry: Will my myopia be passed on to their children? At present, it has been found from many studies that myopia is indeed related to genetics, but the onset of myopia is greatly affected by environmental factors.

That is, myopia is determined both by the genetic traits of the parents and by environmental factors. Why? Listen to me slowly.

Myopia is generally divided into two types: common myopia and high myopia. Common myopia is generally below 600 degrees, can occur from childhood, to the age of 25 rarely develop, by wearing glasses can correct the vision to normal. It is generally believed that common myopia is not hereditary, and its occurrence is usually thought to be caused by factors such as children's lack of eye hygiene.

In contrast, the survey found that people with a family history of high myopia had a higher incidence of myopia than those without a family history of myopia, and that high myopia was also related to environmental factors. High myopia is often above 600 degrees, and it is difficult to correct it even with glasses. Generally speaking, the more severe the myopia, the more likely it is that the parents are inherited.

High myopia is an autosomal recessive disorder. If both parents are highly myopic, the incidence rate of their children is 100%, if one parent is highly myopic and the other is a carrier of the disease-causing gene, the incidence rate of the children is 50%; If neither parent is a patient but only a gene carrier, the incidence is 25% in children; If one parent is highly myopic and the other is normal, the child will not be affected but may be a gene carrier. With that in mind, you should understand why some children as young as two or three years old wear thick glasses.

As mentioned earlier, high myopia is hereditary, but it is also related to the environment, and the acquired environment may aggravate the degree of myopia.

Expert science: Under normal circumstances, the genetic probability of myopia is about 7%.

Both parents are highly myopic (generally above 600 degrees), and the probability of myopia inherited to the baby is about 40%; If one of them is highly myopia, the chance of inheritance can be reduced to 20%; However, if both parents have low myopia, the chance of inheritance is much smaller.

I think the probability is still quite large, and the higher the degree, the higher the probability of inheritance.

There should be some hereditary, after all, he has changed to the genetic level.

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. In this way, when the child becomes an adult, the chance of re-inheritance can also be reduced.

It shouldn't be very likely, after all, it depends on whether the individual's genes have changed.

This should be at 600 degrees is very likely to be inherited, be careful.

I think this is acquired, after all, it is acquired, so the probability is not large.

I think it's definitely possible, there's no absolute.

This mainly depends on the degree of myopia, and it will not be if it is not high.

Many people think that myopia is hereditary, so is myopia really hereditary? Let's find out. There are also many causes of myopia, and everyone must know the causes before systematic treatment.

First of all, poor lifestyle habits and incorrect employment are all key factors that contribute to myopia. In everyone's living habits, there are many people who will gradually become myopic in their work and study, especially students, because of long-term staring at exercise books or exam papers, there is no correct sitting posture in the process of doing homework, and their eyes are too close to objects, and they look at things for a long time, which leads to myopia.

Secondly, because students stare at the classroom blackboard outside the window for a long time, when people's vision is blurred for a short time, the macula under the eyes will gradually adjust the focus, which is very easy to cause myopia in the long run.

The cause of myopia is not only caused by the understanding link, some people will also increase the probability of myopia because of long-term staring at the computer and mobile phone at work. Most of the occurrence of myopia is between the ages of 14 and 20, and the vast majority of them are not easy to improve the degree of myopia after the age of 20.

Myopia does have a hereditary probability, but the heredity of myopia is also interfered with by various factors, and there is no direct evidence in medicine at this stage that myopia is caused by heredity. However, in fact, parents with myopia will increase the risk of myopia in the next generation.

In general, people with relatively high myopia have a relatively high chance of passing it on to their offspring, mainly because there are underlying genetic diseases in the sex chromosomes of the body. If one of the parents has a relatively high degree of myopia, it will increase the chance of myopia in the next generation. About a small percentage of people in our population will have carriers of the myopia gene.

However, this does not mean that the next generation will have myopia, and most of them are caused by acquired irregular lifestyle habits.

People with myopia must understand how to distinguish between occult myopia and pathological myopia, so that they can be accurately treated and corrected. Occult myopia can be improved through later training, as long as you don't have to be overly tired of work and study and training, as much as possible to prevent some incorrect sitting posture, moderately look into the distance, often do exercises around the eyes, reduce the fatigue around the eyes, and it will be gradually improved.

Pathological myopia is more serious, and such myopia groups generally have to go to the hospital for outpatient surgery, and some people must also wear corrective glasses, orthokeratology lenses, and vision correction to repair the conventional eye vision.

Myopia is a widespread eye disease that has long since become a common condition. In order to better prevent myopia, we should pay attention to eye hygiene in daily life, cultivate good eye fatigue habits, maintain a correct sitting posture, pay attention to reasonable arrangement of time, and appropriate eye fatigue.

Generally, both parents in the family are myopic, and the child's inheritance is 100%; If one party is, it is 50%; Neither is the case, then 25%.

The chance of inheritance of myopia is not large, and the chance of inheritance is very small if it is not high myopia.

The chance of heredity is not very large, of course, you need to take care of it when you are pregnant, and secondly, you should also eat more good food for your eyes after the child is born, so that it can play a good role.

It is particularly large and can reach 70%, so mothers must eat more foods with high vitamin A content, and must pay attention to the child's eye safety.

With the continuous development of social economy, in real life, we will encounter a variety of problems, especially for their myopia how to avoid inheritance to the next generation, but also make many friends are very confused, in fact, we must know that the occurrence of high myopia is autosomal recessive inheritance, if the father and mother are highly myopic then the children will have 50% high myopia, but there are also not obvious, most of the cases are caused by environmental factors, so we want to avoid, then we must ensure our own health.

First of all, we must understand such a problem, that is, if we want to avoid the inheritance of myopia to the next generation, we must ensure our own health, when we are pregnant, we must increase the degree of myopia as little as possible, and actively cooperate with the corresponding genetics doctors to carry out relevant rectification and **, but we must understand a problem, that is, the source of myopia is not only a genetic factor, but also may be environmental and developmental factors.

Therefore, we can obviously know that if we want to prevent myopia from being inherited to our next generation, then we must better protect our health, if our parents are highly myopia, then our offspring are likely to be 100% highly myopia, which is what we must know, we want to prevent, we can only ensure our own health, and actively cooperate with doctors to carry out related **, only in this way can we better solve this problem, That's the only way we can get the results I want.

To sum up, we can obviously know that if we want to avoid passing on our myopia to the next generation, then we must better protect our physical health, and we must better cooperate with the doctor to carry out related **, only in this way can we get the results I want, in order to make our body better, this is what we must understand.

Under normal circumstances, a person will often have a certain amount of farsightedness in the eyes after birth, and as the eyes develop, the symptoms of farsightedness generally last until about 10 years old and disappear. After that, the eye returns to normal zero. After the age of 6, if you often use your eyes excessively or incorrectly, or if you have eye trauma, you may be able to become myopia.

However, if myopia occurs before the age of 10, it is often related to genetics.

If you want to avoid passing on myopia to the next generation, try to have eye laser surgery to get your eyes back to normal as soon as possible.

Common myopia is the result of a combination of genetic and environmental factors.

Simple myopia, also known as common myopia, refers to low and moderate myopia below 600 degrees, which is extremely common and can be corrected from childhood to normal. The main symptom is loss of distance vision, which remains normal.

Its occurrence is related to both genetic factors and environmental factors, and it is generally considered to be polygenic inheritance. The occurrence of isolated myopia is obviously related to environmental factors such as poor lighting, poor reading and living habits. But under the same conditions, not all people develop myopia, so its occurrence is the result of a combination of genetic and environmental factors.

High myopia is determined by genetic factors.

High myopia, also known as progressive myopia, refers to myopia with high refraction, significantly elongated eye axis, and atrophic degeneration of the fundus.

High myopia develops mostly in adolescence, except for a few who are congenital, that is, those who are born at birth. Myopia progressively progresses, often above 600 degrees in fully developed people.

High myopia is genetically determined. Surveys of herd heredity have shown that high proximity is autosomal recessive. If both spouses are highly myopia, their children usually develop the disease.

If one parent is highly myopic and the other parent is normal, 10% to 15% of their children will be affected.

If one parent is highly myopic and the other is a phenotypically normal myopia gene carrier, the incidence of high myopia in their children is 50%.

If both partners are carriers of the myopia gene but have normal vision, the incidence of high myopia in the child is 25%.

There have been three consecutive generations in the literature, and it is thought that it may be autosomal dominant inheritance. Given the high frequency of heterozygous for high myopia (estimated at 14% to 18%), the possibility of two consecutive generations of heterozygous marriages cannot be ruled out.
