What causes most adolescents to become myopia

Hello, myopia occurs mostly due to the long anterior and posterior axis of the eye (called axial myopia), followed by the strong refractive power of the eye (called refractive myopia). Myopia mostly occurs in adolescence, and genetic factors have a certain influence, but its occurrence and development are closely related to insufficient lighting, improper reading posture, and working in close proximity for a long time. Most myopia occurs in adolescents, and the degree of myopia deepens year by year during the developmental and growth stage, and it does not develop or develops slowly after maturity.

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.

Now there are more and more people with myopia, and the reasons for myopia are varied, and many teenagers have myopia because of the incorrect way of using their eyes or using their eyes for too long, so find the cause and actively solve it, don't let the situation become more and more serious, the following will introduce to you what are the causes of myopia in teenagers, and those who want to know will take a look at it.

Love sugar

Teenagers have myopia because they eat too much sugar, usually after the sugar enters the body, they need to consume a lot of vitamin B1, and the reduction of vitamin B1 will affect the vision of the eyes.

Genetic factors

Myopia in adolescents may also be caused by genetic factors, high myopia is also an autosomal recessive inheritance, and low and moderate myopia is multifactorial inheritance, and the role of environmental factors is the mainstay. A very small number of pathological myopia eyes are inherited in an X-linked recessive manner.

Excessive use of the eyes

In addition to genetic factors, most adolescents have myopia caused by improper use of their eyes, especially when working at close range, such as learning computers at close range, practicing calligraphy at close range, practicing piano, and may also be due to insufficient lighting, reading too close, too long, unclear or too small fonts and poor posture are related to the occurrence and development of myopia.

Less activity

The reason for the high incidence of myopia in East Asians may be related to the introversion of adolescents and the lack of time to participate in outdoor activities. Of course, it is also possible that the real reason has to do with the intensity of the time spent working in close proximity.

The above is what are the causes of myopia in adolescents, after reading the above introduction, we should also have a certain understanding, teenagers have myopia problems, first of all, we should find the cause, so that we can solve the symptoms, usually do homework, read books, study should pay attention to sufficient light, after 45 minutes of study, you should rest for more than ten minutes, so that the eyes can be rested.

This is because today's teenagers often play with their mobile phones after turning off the lights, and they will often look at the computer, so the incidence of myopia will be higher and higher.

With the popularity of mobile phones, children spend more and more time playing with mobile phones, and secondly, they now have more homework and study pressure.

Because you now often look at your mobile phone when the lights are turned off at night, often watch TV, and do not keep a distance of one meter when you are doing your homework.

1. Incorrect posture of reading and writing homework, and insufficient light are one of the important direct causes of myopia.

2. Sleeping too late: not getting enough sleep.

3. Improper way of eye rest: Many children and parents think that after finishing their homework, they can watch TV, play mobile phones, and play video games to relax, which is to let children rest, which is wrong.

4. Can't look far: Many children's lives are in the classroom, in the house, in the car, and the time for outdoor activities and looking far away is less than 3 hours a day.

5. Picky eating, too much sweets.

6. Procrastination of homework: Many children do homework for 20 minutes, often for an hour.

7. In the stage of pseudomyopia, they do not pay attention to, do not **, and blindly wear glasses.

8. Too much early childhood, too long exposure to computers, television, too close distance.

9. Nutritional deficiencies, or other diseases.

Now there are more and more children with myopia, and they are getting younger and younger. Children's myopia not only affects children's life and learning, but also makes parents worried. Therefore, it is necessary to take medication in time** to improve myopia.

It is recommended to take Leyan Vision Nutrients, take it with warm water, and insist on taking it for a period of time, the myopia degree will be reduced, and the vision will be improved. It will not affect the child's future education and employment.

Myopia is already a norm in society, almost half of the people in China have myopia, and most of the myopia is more common among teenagers, as far as the current statistics are concerned, China's myopia is nearly as high as 600 million people, it can be seen that the incidence of myopia is so high, so now there are more and more myopia among teenagers, what is the reason for this?

First, the gradual rise of myopia in adolescents has a lot to do with long-term contact with electronic products, especially in today's society is the Internet era, teenagers use mobile phones or computers for a long time, it will cause certain damage to the eyes, when the eyes are overtired, it will lead to dry eyes, eye pain and other uncomfortable symptoms aggravated, if not improved in time, it will cause myopia.

Second, the Internet era has made many teenagers have the habit of staying up late, often staying up late will lead to eye nerve dysfunction, eyes can not get proper rest, long-term congestion and fatigue in a state of myopia, therefore, teenagers must ensure adequate sleep in any case, ensuring adequate sleep is the key factor to prevent myopia.

3. Myopia also has certain genetic factors, such as if someone in the family suffers from myopia, the probability of myopia in adolescents will be relatively high. In addition, poor eye habits are also the cause of myopia, often reading books at close range, writing posture is incorrect, will lead to eye myopia, especially long-term reading and writing in too bright, too dark environment, will make the crystalline muscles continue to tense, will produce pseudomyopia.

In general, there are many reasons for myopia, the appearance of myopia can not be dealt with by simple methods, even if it is corrected through myopia, it can only improve the symptoms, and can not achieve the best effect, no product can have the best effect on myopia, therefore, I hope that everyone will pay attention to myopia, and must protect their eyes and use their eyes correctly.

Because of the increasing pressure on teenagers nowadays, teenagers study for a long time every day, and often stare at electronic products, so myopia is increasing.

Children will often look at their mobile phones, computers, and iPads in their lives. will cause such a problem, and will also turn off the lights to play with the phone.

It is because today's teenagers are more fond of using electronic devices and have more homework, so they are more and more energetic.

The incidence of myopia in adolescents continues to rise, which is due to incorrect eye use or the current pressure of learning, and it is frequent near operation from about 3-4 years old. The state stipulates that the abolition of pre-school education is to avoid premature use, but the current domestic situation is not optimistic. Because parents are afraid of losing at the starting line, the learning in nurseries and kindergartens has never been relaxed, resulting in the repetition of first-grade admission courses or gradual decline in vision, and glasses must be fitted, otherwise it will cause strabismus or amblyopia.

Although the occurrence of myopia is related to congenital heredity, it is mainly caused by improper use of eyes. There is a concept that must be clear, myopia cannot be cured at present, no matter what method is used, it only relieves the symptoms of myopia.

It is usually related to genetics or eye problems, or it may be caused by incorrect posture.
