Is myopia hereditary? Will the offspring of excessive myopia also suffer from myopia?

I remember when we were in biology class in junior high school, the teacher told us about genetic inheritance, such as the height of the parents, the height of the offspring will also be taller, and the double eyelids and single eyelids of the parents will also determine whether the single eyelids or double eyelids of the next generation will be passed on to the next generation. But on that day, I happened to see a report that myopia can also be passed on to the next generation, and I still thought it was congenital amblyopia, so would it be passed on to the offspring? It turned out not to be.

It has been concluded that if your myopia is acquired myopia, it will not be passed on to the next generation, but if both husband and wife are highly myopia, that is, the degree of high myopia is above 600 degrees, if both husband and wife are highly myopia, then the probability of the next generation will suffer from myopia is relatively higher than that of those myopic but small couples born to babies with myopia. <>

Because of high myopia, it is also known as pathological myopia. Therefore, this kind of myopia is very likely to be inherited, but generally this pathological nearness of this pathological myopia heredity only has a little effect, in fact, myopia still depends on the influence of the environment and the influence of the eyes, for example, the husband and wife are highly myopia, but the baby is not checked out of myopia, that is healthy, if the child plays with mobile phones the day after tomorrow, plays games and watches too many electronic products will also be myopia, which is a factor that can be controlled. <>

Therefore, in order to avoid the next generation from suffering from myopia, it is necessary to reduce the time that children look at mobile phones, computers, and TV, and eat more foods that are good for the eyes, such as supplementing more lutein, because of the effect of lutein in protecting the eyes? Eat more green vegetables, which can protect your eyesight, and supplement more vitamins, which can help your eyes fight fatigue and anti-oxidation.

Many doctors will also recommend that children go outdoors more and see more blue sky, so that the probability of suffering from myopia will be much less, of course, when the sun is very strong, there is no need to go out, otherwise ultraviolet rays will also hurt the eyes.

Did you get that in front of the screen?

Myopia is hereditary, but those with a low degree will not be inherited, and only those with a particularly high degree will be inherited.

Myopia has a certain possibility of inheritance, generally the higher the degree, the greater the possibility of inheritance, the offspring of excessive myopia has a high probability of inheritance, and will not necessarily suffer from myopia.

It is not necessarily myopia, but the probability of myopia will increase, myopia can indeed be inherited, but there is a certain chance, if you use your eyes too much when you are a child, you will also be myopia.

Myopia is inherited, but offspring with excessive myopia will not necessarily develop myopia, which is related to recessive genes.

I don't know when it started, but people around me said that if both parents have myopia above 600 degrees, the next generation will be born with myopia. In our daily lives, we do see many children wearing thick glasses at a very young age. For this reason, many parents of myopia are very alert and have been searching online or consulting a doctor.

So, is this news really reliable?

In fact, parents with myopia of 600 degrees or more will not pass it on to their children. Parents who carry the myopia gene will pass it on to their children. It's the genes that are inherited, not the myopia itself.

Therefore, parents with high myopia do not need to panic or worry too much about the genetic problem of myopia. There are two types of myopia: isolated myopia and high myopia.

Simple myopia refers to common myopia below 600 degrees. Currently, there is no clear evidence that this myopia is hereditary, so you can rest assured. Is high myopia certainly hereditary?

High myopia can be divided into pathological myopia and physiological myopia. In general, pathological high myopia has a genetic factor and is hereditary, while physiological high myopia does not. Therefore, as long as myopia reaches 600 degrees or more, it will not necessarily be passed on to the next generation.

If you want to see exact data, then according to the results of the Demographic Genetic Survey, if both couples are highly myopia, their children usually get sick. One is highly myopic and the other is normal, and their children have a 10%-15% incidence。One is highly myopic and the other is a gene vector with a normal phenotype.

The incidence of high myopia in children is 50%. If both partners are carriers of the gene for myopia, but have normal vision, the incidence of high myopia in children is 25%.

Although high myopia may be inherited to the baby, there is no need to panic. Expectant mothers can try to reduce the effect of genetics on their babies in various ways: First, the rubella vaccine should be given in advance.

Infection with rubella virus in the first trimester of pregnancy can directly affect the development of the baby's eyes and cause congenital cataracts. Second, get plenty of sun. Proper outdoor sun exercise is conducive to the absorption of calcium, which is very conducive to the development of fetal optic cells and cornea, which is called light wave prenatal education.

Third, pay attention to the intake of adequate vitamins. Vitamin A, vitamin B1, vitamin B2 and vitamin C can all play a good role in eye development, improving the eye nervous system, and preventing cataracts.

Experts said that from the analysis of the results of eye diseases, the rate of myopia in family members with a family history of myopia is higher than that of those without a family history of myopia, and the closer the kinship, the higher the prevalence rate. The higher the degree of myopia of parents, the higher the prevalence of children, and children with myopia genes have significantly worse resistance to adverse eye environment, and the risk of inducing myopia is higher. These results indicate that the onset of myopia is related to heredity.

Moreover, the survey shows that if both parents are highly myopic, the children born are basically myopic. If one parent is highly myopic and the other is a carrier, 50% of the children born are myopic and 50% are carriers. If one parent is highly myopic and the other parent is a healthy person with normal genes, the child is not at risk of developing high myopia.

First of all, it is necessary to take your child to have his vision checked regularly. Even parents who are sighted should take their children to have their eyes checked regularly. Regular testing can monitor your child's vision changes and detect early vision problems in your child.

Now there are ophthalmic testing products (such as: pupil vision, home refractor, etc.) can be used to test vision at home, which is very convenient, and parents must not be troublesome and ignore their children's vision testing.

Secondly, cultivate children's good eye habits, basically myopia is caused by bad eye habits. For example, using your eyes for a long time, sitting incorrectly, reading a book or playing with electronic products in a poorly lit position. Parents should pay special attention to this issue.

Third, regular outdoor exercise. Give your child more opportunities to get in touch with nature and do more outdoor activities on green grass. Green light is short-wavelength light, and short-wavelength light has a short focal length, which is conducive to the prevention and control of myopia.

Outdoor exercise can also help children broaden their horizons, so that the ciliary muscles can be fully relaxed, reducing the chance of children suffering from myopia.

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%.

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

It is indeed possible that a high degree of myopia will be passed on to the next generation.

This is very possible, because myopia is also a genetic disease after all.

In general, myopia is not genetic, and it is usually not inherited.

According to scientists, myopia is hereditary and irreversible.

It will be inherited. But it should be explained on a case-by-case basis

If both parents are highly myopic, the chance of myopia in the next generation is higher;

If one parent is highly myopic and the other is a carrier of the gene, the chance of passing it on to the offspring is also high.

If both parents are carriers of disease-causing genes, although they are not myopic, their disease-causing genes will be passed on to their children, and children with 2 myopia genes will have a higher chance of becoming myopic.

We want to eat more foods that are good for our eyes:

No matter how old you are, it is very necessary to protect your eyes, and the following nutrients are very good for protecting your eyesight

Lutein: Green vegetables have this lutein, pumpkin is the same, lutein has a good eye protection effect, we can cook some with water when we make it for children, put it in noodles or put green vegetables in soup, so that children will also love to eat.

Vitamin C, Vitamin A:

Vitamin A is the main nutrient to maintain healthy vision, vitamins can also help the eyes antioxidant, can also enhance children's physique, carrots are very rich in vitamin A, vitamin C foods include oranges, kiwi and other fruits, we can buy these fruits for children to eat.

In the case of myopia, it is generally a state caused by insufficient attention to eye hygiene and lack of protection of the eyes, so myopia will not be inherited from offspring.

However, if you want to protect your eyesight more effectively, you must pay attention to learning and communicating with professionals, and it will be better to master more skills and methods of intellectual protection.

1. Respond in a timely manner when talking.

First of all, we must know how to respond, if others are very interested in saying a lot of things, and you don't have any expression, it will make people feel very embarrassed or uninteresting, so that the light words can only end hastily, and it will not help your language communication, so you should respond to others in a timely manner when talking to others.

2. Communicate attitude and respect each other.

The attitude when communicating is also very important, you should communicate modestly and friendly with the other party when communicating, and respect each other when talking, keep the body leaning forward during the conversation, not leaning back, and you can't lean your whole body on the chair, so that the whole person will look lazy.

3. Know how to listen when talking.

Listening is also a point to pay attention to in communication, when talking to others, we must take into account the feelings of others, but also listen to what the other party expresses, so that we can better communicate in language, otherwise it is like "chicken and duck talking", so that communication can not achieve the effect at all, and it is easy to misunderstand.

4. Don't always be self-centered.

When talking, we should also pay attention to an important point, don't always think that what you say and do is very important, always take yourself as the center, and other people's is not important, this situation is to be eliminated, which can easily cause others to be disgusted, and will also leave a bad impression on others.

The mild power of myopia is generally not hereditary. If there is a genetic tendency after reaching a high degree of myopia, mainly because the myopia has a power of more than six, the eye axis can be inherited to the next generation, but the myopia caused by heredity is not born, but it is more likely to appear myopia in the process of daily learning and life, so patients with high myopia in one parent need children to develop good eye habits from an early age, and it is recommended to avoid watching TV or mobile phones as much as possible within 2 years old. After the age of 2, you should not watch TV for more than half an hour a day, and you can go to the hospital at the age of 3 to have your vision checked, and if you have vision loss, you need to be diagnosed by optometry.

Depending on the results of the examination, myopia requires glasses.

If the power is deep, there is a possibility that it will be passed on to the child.

There is a certain possibility that it will affect future generations

Acquired myopia is not inherited unless all your germ cells are mutated to carry the gene that causes myopia. And the gene is dominant, parents each give their children only half of the genes, and there are XY chromosomes. y Only the father has and only the ode shirt let one (that one in the father:

xy, female: xx), which also determines the male and female spoken. In general, the possibility of causing the disease depends on the family's medical history.

If there is really no one in the family who is nearsighted or has reached some specific relationship (more complicated, I won't explain it in detail). Then the likelihood of a child's myopia is minimal. The general myopia is a multifactorial inheritance, which is subject to both the laws of heredity and the involvement of environmental factors.

At school age, because the eyeball is not yet mature, it is in the near vision environment too early or too much time, then environmental factors form the main cause of myopia. Genetic factors are the internal causes of myopia, the foundation, and the biological prerequisite in the development of myopia, while environmental factors are external factors that determine the reality of myopia, mainly due to long-term nearsightedness and formed through the action of genetic diathesis.

I discussed this issue with my classmates when I was in college, and we both felt that biologically it was not hereditary. But why is it that some people are prone to temporary laughter, and some people are not short-sighted, and we read books every day and play with our mobile phones every day? Later, they unanimously felt that myopia is not hereditary, and if it is inherited, it should be myopic at birth.

There may be people who are prone to myopia, and this constitution will be inherited. This is just a personal opinion, and it does not fit the problem.

Now people say that myopia will be inherited, and if it can be inherited, it must be genetically speaking. Genes don't change, so inheritance is unlikely.
