There is a certain genetic predisposition to the cause of myopia

Myopia is not absolutely determined by congenital factors, in addition to congenital factors, there is also a part of the reason for acquired habits. If parents can let their children develop healthy eye habits, pay attention to eye protection in daily life, then they can also try to avoid their children's myopia, generally speaking, if both parents have myopia, then the chance of children born to suffer from myopia is higher than others, of course, this can also be through acquired conditioning to avoid myopia. If it is inherited to the baby, it can be detected as early as 1 to 3 years old, and some do not appear slowly until the age of 5 or 6.

There are too many factors that cause myopia, for example, I have seen a myopic child, because of the lack of long-term vitamin B intake when he was a child, his iris is congenitally softer than other children, so that the eye axis will develop very long, and he is more likely to be myopia. Just because both parents are nearsighted does not mean that children will be born with myopia. The causes of myopia are very complex, not only due to genetic problems, but also to the external environment.

If one of the parents is highly myopic and the other is a carrier of the myopia gene, the chance of passing it on to their offspring is about 30%.

From the perspective of the occurrence of myopia and the family lineage, it is more likely that multiple genes interact with each other to determine whether myopia occurs and the severity of myopia, so myopia is polygenic inheritance. If one of the parents is highly myopic and the other is neither myopic nor myopic gene carrier, the baby will not be highly myopic, but may be a myopia gene carrier.

Children born to calcium-deficient pregnant women are three times more likely to develop myopia in their teenage years than pregnant women who are not calcium deficient. Therefore, pregnant women should also consume sufficient calcium during pregnancy. The pathogenesis of low-grade myopia (less than 600 degrees) is still debated.

The incidence of myopia in yellow people is higher than that in Caucasians and blacks, the incidence of myopia in people with a family history is higher than that in people without a family history, and the incidence of myopia in first-degree relatives of patients with myopia is much higher than that of emmetopia, and these studies show that myopia is related to genetics.

There is no genetic factor, and myopia is acquired, not hereditary, so there is no need to worry about such a situation.

I think both parents have reached a high degree of myopia of more than 600, the genetic factor is still relatively high, if both parents wear glasses, but the degree is not high and it is not congenital, the probability of heredity in this case is not high, it is recommended that parents take their children to a regular ophthalmology for a comprehensive examination!

There is a great genetic factor to myopia, some people may be born with the gene for myopia, while some people have myopia that is acquired.

Myopia is genetic. In particular, both parents are highly myopic and have a particularly high chance of inheriting offspring.

There are two main causes of myopia, one is genetic factors, and the other is caused by long-term eye use. So from here, you can see that myopia is definitely hereditary, and the hereditary proportion of myopia in China is very high. Why?

Because we all look at the many intellectuals around us, many of our children have parents who are mildly myopic or highly myopia. If the child's parents are both highly myopic, the proportion of the child with high myopia will be greater than 90%, so myopia is a hereditary disease inherited by polygenic factors.

Yes, genetic factors are very large, and if the parents have a high degree of myopia, the child is particularly likely to be myopia.

There is a genetic factor, some people are congenital with myopia, which is passed on to the next generation.

The condition of the eye is related to genetics. But there is no absolute and inevitable relationship. Genetic factors are only one of the causes of eye conditions.

Eggs can turn into chickens, just a possibility. If the temperature is not right, it cannot become a chicken. Put the egg in the refrigerator and freeze it, it will always be an egg; Put it in the pot and it becomes a good meal.

There is a similar situation with the eye, where the farsighted eye can also become myopic under conditions where myopia can occur. Under normal circumstances, a farsighted eye can become an emmetropic eye.

Full-cycle vision health management.

For a person, myopia must be a bad problem, because myopia will bring certain inconvenience to future life, when exercising, you will not be able to see the road ahead, it is also very inconvenient when swimming, and even some people are worth wearing glasses is not good-looking.

Well, in fact, myopia has a genetic factor. It has been reported that 65% of myopia is due to genetics, and the rest is due to an environmental or behavioral influence. If both of your parents are short-sighted, then you are also likely to be short-sighted.

Because after all, the genes in our bodies are inherited from our parents, so if they are also short-sighted, they may also be inherited from their children. If it is congenital myopia, then you have to wear glasses since childhood, and it may even be the kind of glasses with high myopia, then its lenses are very thick, and the impact on the future eyes is also very inconvenient.

From a genetic point of view, a large number of reasons for myopia are due to genetics. If it is only because of acquired eye habits that cause myopia, in fact, the probability of heredity is very small, which means that the child is inherited from his parents' myopia, so in fact, the myopia of his inherited parents is pathological myopia. But in general, if your parents have myopia, even if the vision problem is corrected the day after tomorrow, there is still such an effect in the genes, so it will still affect the child in the future.

Most people may think that their myopia is caused by an acquired behavioral habit, but in fact, it is all because there is such a genetic factor in their genes. Therefore, when you have a little incorrect eye habits, it may affect your eye vision. Just like some people who look at their phones in the dark every day, but their eyesight is still very good, then his parents may be people who are not nearsighted.

But on the contrary, if your parents are myopia, if you read too closely, or sit incorrectly, and play with your mobile phone at night, it will largely cause you to have myopia, so myopia is affected by your parents' genetics to a certain extent.

There is a genetic component to myopia in the eye. The reason why I say this is because some people are born with poor eyesight. If both parents are nearsighted, the likelihood of myopia in the child will also increase.

There is a genetic component. Because the possibility of inheritance is very high, it is a recessive genetic factor of chromosomes.

There are genetic factors in myopia, and if the father or mother has a particularly serious myopia, it will have a certain impact on the child's vision, which has also been found through scientific research.

Myopia is genetic, and according to relevant studies, 65% of myopia is inherited. The rest is the acquired environment and the individual's behavior. If both parents are nearsighted, then there is a high probability that the child will also be short-sighted.

Because the genes in our bodies all come from our parents, and when we give birth to children, we will also inherit the genes of our parents. If you are congenital myopia, then your child will need to wear glasses at an early age, and the eyes may develop into high myopia.

Although a child's eyes will be affected by their parents, if they are used wisely, they can still prevent their eyes from becoming nearsighted. Nowadays, many children are very fond of playing with mobile phones, and if they stare at the mobile phone screen for a long time, it will cause eye strain. Your child will not relieve eye strain and will often continue to play.

In this case, parents must guide their children in time and tell them not to play with their mobile phones for a long time. Let your child develop good eye habits, learn to do eye exercises, and let your child stick to it.

Most people have myopia caused by nurture in their eyes, and if both parents are nearsighted, it is basically caused by habits such as incorrect sitting posture and improper use of eyes. If you want your child to be free from myopia, then parents must exclude the influence of the environment. When children read and learn, let them learn to relax their eyes.

At the same time, cook more carrots for children, the carotene in radishes can play a role in preventing myopia.

There is a genetic component. Because myopia is likely to be caused by family inheritance, it is also related to the genes of parents.

Myopia can also have a genetic factor. Because there are some people with high myopia, they already have this myopia gene in their genes, so they will inherit it.

There are genetic factors, if the degree of myopia of the parents is particularly severe, it will directly affect the child's vision, and it will also make the child myopia.

Myopia can be hereditary, and in clinical medicine, the inheritance of myopia belongs to multifactorial inheritance, but it is not that parents are myopic and children will be myopia. If the parents have high myopia, the child has a higher chance of inheriting myopia. Because high myopia is closely related to pathological myopia and retinal detachment, patients need to pay attention to preventing the occurrence and progression of myopia.

After years of clinical research, and related data show that myopia is a disease with a genetic predisposition, and the specific genetic mechanism is not yet clear, but heredity is a very certain cause, and the higher the degree of myopia, the greater the chance of inheritance.

If one of the parents has myopia, the chance of myopia in the next generation is basically about 5%-10%, and if both parents have high myopia, the chance of the child developing myopia will rise to more than 10%. Therefore, myopia is a disease with a genetic predisposition, in order to avoid this situation, we must pay attention to maintaining reasonable eye habits, try to slow down the growth rate of myopia, and only control the myopia degree in a relatively low state will reduce the probability of heredity.

The inheritance of myopia is genetically determined. Many genes can affect the development and structure of the eye, which can affect vision. If a parent or other close relative has myopia, the child is also at higher risk of developing myopia.

However, genetics is only one factor in myopia, and environment and lifestyle can also influence the development of myopia. For example, prolonged close use of electronic devices, lack of outdoor activities, and poor study posture can all lead to the occurrence and progression of myopia.

The occurrence of myopia is related to genetic factors, so myopia has a certain hereditary nature. The occurrence of myopia is mainly related to genetic and environmental factors, and the occurrence of myopia is affected by genetic factors and acquired environmental factors.

Genetic factors: Myopia has a certain hereditary nature, especially the possibility of inheritance of high myopia is higher. Studies have shown that if both parents are highly myopic, a child is more than 4 likely to develop high myopia....

Myopia does not occur. 2. Environmental factors: The occurrence of myopia is affected by acquired environmental factors. For example, children spend too little time outdoors and too much time reading at close range, which may lead to myopia in children.

The causes of myopia are not fully understood, and most scholars believe that myopia is related to a variety of factors, including genetic factors, environmental factors, and poor eye habits.

Essential**. Genetic factors.

A large number of surveys have shown that myopia has a certain genetic tendency, and it is often seen that families are clustered, and both parents or one parent are myopic, and the likelihood of myopia in children will increase. Among them, it is clear that the occurrence of high myopia is autosomal recessive.

Environmental factors. The incidence of myopia in patients with long-term near eye use is relatively high, which is also the main reason for the high incidence of myopia among adolescents in China. If you add to the factors such as poor ambient lighting, too small or blurred reading handwriting, too long continuous reading, and lack of outdoor activities, it will further promote the occurrence and development of myopia.

Predisposing factors. Studies suggest that micronutrient deficiencies, nutrient imbalance and air pollution may all be predisposing factors for myopia.

With the popularity of electronic products in recent years, long-term close viewing of electronic screens may also promote the development of myopia.

The causes of myopia are divided into two primary types: simple and pathological**.

The mechanism of the occurrence and development of simple myopia is based on internal factors (genetic factors) and formed under the action of external factors (environmental factors).

Pathological myopia is directly related to genetics.

Therefore, myopia will definitely be inherited, especially pathological myopia.

Heredity is the basic attribute of living things, so any trait will be inherited from generation to generation, but we like the inheritance of advantages and the inheritance of disadvantages.
