What are the causes of myopia in adolescents and children?

Due to the continuous development of electronic technology, children are exposed to electronic products more and more, and vision impairment has become a common phenomenon. In the face of children's myopia, parents seem to be powerless, but in fact, there are some ways we can prevent the child's vision from getting worse and worse

1. Have good eye habits, pay attention to proper posture, especially when reading in a car, walking and in bed, and then pay attention to the eyes should rest for about 10 minutes after 1 hour.

2. Choose eye drops for eye fatigue, because children are prone to fatigue and dry eye because they spend more and more time with their eyes. So it's okay to use eye drops, but be careful not to use them too often.

What are the ways to prevent myopia?

1. Don't use your eyes for too long at close range. When resting, you can look out of the window or do some outdoor activities to fully relax the ocular accommodating muscles.

2. Pay attention to the close-up use of eyes, to see if the light is moderate. It is recommended to choose incandescent LED light is softer, the eyeball is easy to adapt, pay attention to the light is too strong or too dark will cause eye fatigue.

3. Electronic products must be controlled such as TV, computer, iPad and mobile phone time, it is recommended that the total time used in a day should be controlled as much as possible in 1 hour.

The first is that the mobile phone browsing time is too long, and the game is too attractive.

Then there is too much pressure to study, in addition to the burden of schoolwork, there are also a variety of remedial courses.

The impact of television is not small.

Teenagers use their eyes unscientifically.

What are the main causes of myopia in adolescents? 1. Parental geneticsMyopia has a certain genetic predisposition, and if one of the parents is highly myopic, the probability of the child becoming myopic is also higher than that of the parents who are not myopic. In particular, if both parents are highly myopia, the child is more likely to be myopic in the future, and the child's myopia control effect may not be good.

2. Poor eating habitsPoor eating habits can also affect the health of your child's eyesight. Drinking cola or eating sweets often causes excessive sugar intake, which produces a large amount of acid in the blood, which may neutralize with excessive calcium salts in the blood and affect calcium absorption. The outermost sclera at the back of the eyeball requires calcium, and calcium absorption is insufficient, which reduces the elasticity of the sclera and becomes harder, so the eyeball is more likely to be elongated, resulting in axial myopia.

3. Influence of environment and eye habitsCurrent research suggests that sunlight can promote the release of dopamine in the retina, thereby delaying the growth of the eye axis, thereby helping to prevent myopia. At the same time, outdoor activities can also help protect your eyesight because of your wide field of vision.

Environmental factors and the reduction of outdoor activities are the main causes of myopia in children.

Patients with general myopia:

1. Don't read in too strong or too dark light;

2. Don't read books on swaying buses, cars, or boats;

3. Do not look directly at the luminous body with too strong light;

4. Maintain a true posture and keep a distance of one foot from the book;

5. Do not contact the video screen (computer, TV) for too long, so as to combine work and rest;

6. The distance between the person and the TV should be more than 5 times the diagonal length of the fluorescent screen or more than 3 meters.

7. There should be ambient lighting when watching TV.

8. Avoid playing games and avoid obsession with the Internet.

These are all possible, and today's children are doing their homework and learning in the wrong posture, playing with mobile phones and computers.

Parents must help their children develop good eye habits.

The intensity of the light, eating habits, sitting posture, and high myopia of parents may all cause myopia in children.

One is that children and teenagers are increasingly dependent on electronic products and lack time for extracurricular activities; Second, many children do not have good study habits. <>

It can be seen that with the popularization of mobile phones, almost everyone has a mobile phone, and they can't do without mobile phones at all. Now children, teenagers are not the same as before, from the door to be able to access electronic products, many children have been exposed to mobile phones since childhood, some children have a stronger learning ability for electronic products than adults, many children have taken electronic products as a necessary game product in life. Usually, you can use your mobile phone or tablet to watch cartoons and play games, which is much more interesting than going out to play.

Because parents did not stop it in time, some children are too dependent on electronic products, children do not eat well, do not study well, just to play with mobile phones, when they were young, they stared at their mobile phones every day, and they were myopic at a young age, and the degree is getting higher and higher.

Children are pampered, the learning attitude is not correct, do not develop a good study habits, usually study is how to be comfortable how to come, parents are busy with work, can not always stare at the child, slowly the child will develop a habit of changing. There are also many people who stay up late, don't sleep at night, don't finish their homework in time during the day, and wait until the night is close to sleep, and the homework is still delayed, so their eyes will be short-sighted after a long time. <>

This is only two reasons, and there may be genetic factors, and now parents are also very myopic, which may affect their children. Children usually use their eyes excessively, parents must remind their children to take their children out for a spin and feel the nature. No matter how busy you are, you can't ignore your child's health.

More and more children wear glasses at a young age, and their eyes are very fragile and cannot withstand our tossing.

Spend more time outdoors and feel the sunshine and greenery, so that your eyes can be relaxed. Encourage your child to develop good study habits, especially when sitting. In the face of children's dependence on electronic products, parents must not relax, and indulging again and again is the greatest harm to children. <>

The main reason is that children and adolescents watch TV, mobile phones and other electronic products for a long time, and because children at this age are under more pressure to study and do not have good eye habits, the incidence of myopia will increase.

There is a lot of academic pressure, and such pressure can cause such problems. Without parental love, without parental love, they will also play games, and if they play more games, they will be short-sighted.

There are many factors caused by the increasing rate of myopia, such as the increase in electronic products, tablet computers, and mobile phones.

Because there are more parents with myopia nowadays, some children also inherit their parents' myopia. At the same time, there is a lot of pressure to study, so children do a lot of learning, and they may not use their eyes properly. And now electronic devices are also entering every home.

First of all, it is related to watching mobile phones and TV for a long time, long-term radiation will cause damage to the eyes and directly affect vision, and secondly, it has a lot to do with eye habits, and the intensity of light when watching and writing is also one of the factors affecting vision.

Because they usually use their eyes too much and often go to play with their mobile phones and watch TV, they are nearsighted, and they don't look up when they do their homework.

Myopia in children may be related to factors such as genetics, too strong or too weak light, poor eye posture, and insufficient eye relaxation.

1. Myopia has a certain genetic tendency, often familial clustering, and both parents or one parent are myopia, and the possibility of children developing myopia will increase.

2. Too strong or too weak light may cause myopia. There is a small black dot in the middle of the black eyeball, called the pupil. How much light can enter the eye is determined by the pupil.

When the light is too low, the pupils dilate to let in more light. When the light is too strong, the pupils shrink, reducing the amount of light coming in. Dilated or narrowed pupils can tighten the ciliary muscle, making it difficult for the lens to adjust to a flat state, which can easily lead to myopia.

3. Poor eye posture may lead to myopia. Wrong sitting posture, lying down, lying on the stomach to look at things, will make the eyes unconsciously too close to things, long-term close use of the eyes will increase the burden on the eyes, the ciliary muscle contraction for a long time, can not be relaxed, will increase the risk of myopia.

Incorrect posture for reading and writing homework, and lack of light are one of the important direct causes of myopia. 2. Sleeping too late: not getting enough sleep.

The main reason for myopia in children is to watch too much TV, and it is best not to let children play with mobile phones, and then stay away from books when reading, so that they are not easy to be myopia.

The main cause of myopia in children is excessive eye use or wrong habits.

First, the light is not strong or weak.

Are the lights bright enough? I'm worried that the light is too dim and it will affect my child's vision. "That's our general idea.

But in fact, the light of the child reading and writing is not too dim, on the contrary, it is too bright. Excessive light can make your child's eyes tired easily, so your child needs a soft light that comes from the front left of your child. Therefore, when children read and write at night, they can choose a lamp that can adjust the brightness and adjust the brightness to soft.

Second, indoor games are the mainstay.

Nowadays, most parents out of consideration for the safety and convenience of their children, in most cases, let their children move at home, mainly indoor games, in this case, children are in the case of close eye use, so that their eyes are very burdened.

Third, there is too little time for outdoor activities.

Now, the space we live in is too small, and most of the children are indoors, there are a lot of time to use their eyes at close range, and the children's eyes are very adaptable, they will adjust themselves to adapt to this distance, and the opportunity to watch TV and play computer will also increase.

Children's myopia is mainly caused by congenital genetic factors and acquired environmental factors. Environmental factors are mainly children's eye habits, such as excessive use of electronic products, reading books in dim light, etc., it is recommended that parents pay close attention to their children's eye health and correct them in time.

1. The living environment, high-rise buildings rise from the ground, abandoned courtyard houses go to towers, the environment for close eye use is increasing, and the environment for long-distance eye use is decreasing.

2. Eye time, forced to study, play computer, watch TV, play Apple, the time of close eye use is increasing, and the time of long-distance eye use is decreasing.

3. Dietary collocation, junk food, carbonated drinks, sweet and greasy snacks are increasing, fresh vegetables and fruits are eaten less, plus antibiotic milk, gelatin jelly and other toxic foods.

4. Outdoor activities, the healthy growth of children is inseparable from running, jumping and jumping, and now the children's sitting and lying space time is increasing, and the activity venue and time are decreasing.

Therefore, if you care about the healthy growth of children, it is best to find ways to increase the number of things that are decreasing and reduce the number of things that are increasing.

Nowadays, there are more and more people with myopia, and they are getting younger and younger. Myopia in adolescents not only affects their study and life, but also makes parents worried. In fact, as long as the vision nutrition is supplemented in time, it can be a good prevention and ** myopia in adolescents.

Generally, doctors recommend taking Leyan Vision Nutrients, taking it with warm water, generally about 7 days to see the change, insist on taking it for a period of time, can protect eyesight, prevent and ** myopia, and improve the vision of teenagers.

At present, the mainstream theory of the cause of myopia is genetic and environmental factors, and generally myopia is a multifactorial inheritance, which is not only subject to the laws of heredity, but also has the participation of environmental factors.

Genetic factors are the internal causes of myopia and the biological prerequisite for the development of myopia. Environmental factors are external factors that determine the reality of myopia, which is mainly due to long-term nearsightedness work and is formed through the effect of genetic diathesis.

In the current society, children are in a nearsighted environment too early or too much time before the school-age eyeball is mature, and environmental factors form the main cause of myopia.

Ophthalmologist Shi Yongli Profile: Director of the Department of Ophthalmology, working in a tertiary hospital for more than 10 years, good at cataract, glaucoma, pterygium surgery and various ocular surface diseases, dry eye syndrome, keratitis and pigmentitis, fundus disease, various complex eye diseases, systemic diseases, ocular complications and difficult diseases.

The exact mechanism of myopia formation has not yet been fully understood, and it is generally believed to be the result of congenital heredity and acquired environment. Myopia has a certain hereditary nature, especially high myopia, and the genetic mechanism has not been fully elucidated. Both parents are highly myopic and the chance of myopia in their offspring is almost 100%.

Acquired environmental factors, including modern urban life, less time for outdoor activities, lack of broad vision, too early exposure to electronic products and prolonged close reading, excessive burden of homework in and out of class, unhealthy diet and sleep, etc., are all related to the development of myopia.
