Abstract: now the burden of eyes is really too heavy. If genetic factors are not considered, it is related to the overall living environment. An obvious example is Japan. Before the Second World War, the incidence of myopia was very high. During the Second World War, many people went out to fight, and few people were short-sighted., Summer vacation is a time for students to relax physically and mentally, but at present, the prevalence of children’s myopia is rising, which seriously threatens children’s health. At the same time, some parents lack scientific ophthalmology knowledge and blindly believe in advertising, resulting in spending a lot of time and money and failing to effectively treat their children’s eyes. The reporter recently interviewed two ophthalmologists. They comprehensively, scientifically and objectively introduced the causes, prevention and treatment of myopia, and clarified some vague understandings about myopia in people’s daily life., The long-term close use of eyes is the cause of myopia. It is unscientific to say that children should stay away from glasses all their life. Now, there are more and more students with myopia.

During the Second World War, many people went out to fight, and few people with myopia. After the war, the country developed education, and the number of people with myopia increased again., The eye is like a camera. Suppose that an automatic camera is normally set to see objects at a distance of 5 meters. When you let it see an object at a distance of 3 meters, the camera automatically focuses to see the close object. After that, it returns to the normal focal length. If we always let it look at nearby objects, the camera simply won’t adjust the focal length, but it’s best when it’s fixed at 3 meters. The principle of eyes is the same as that of cameras. Today’s children are born, most of them watch close things, including reading, surfing the Internet and watching TV. Although people are born with their eyes in a hyperopia state, people always use their eyes close, and it will automatically put the focal length close. How can I get close?

summer vacation is a time for students to relax physically and mentally, but at present, the prevalence of children’s myopia is rising, which seriously threatens children’s health. At the same time, some parents lack scientific ophthalmology knowledge and blindly believe in advertising, resulting in spending a lot of time and money and failing to effectively treat their children’s eyes.

long-term and close use of eyes is the cause of myopia.
it is unscientific to say that children stay away from glasses all their life. Now, there are more and more students with myopia. What do you think of this phenomenon from the perspective of doctors?
now the burden on the eyes is really too heavy. If genetic factors are not considered, it is related to the overall living environment. An obvious example is Japan. Before the Second World War, the incidence of myopia was very high. During the Second World War, many people went out to fight, and few people with myopia. After the war, the country developed education, and the number of people with myopia increased again.
the eye is like a camera. It is assumed that an automatic camera is usually set to see objects at a distance of 5 meters. When you let it see an object at a distance of 3 meters, the camera automatically focuses to see the close object. After that, it returns to the normal focal length. If we always let it look at nearby objects, the camera simply won’t adjust the focal length, but it’s best when it’s fixed at 3 meters. The principle of eyes is the same as that of cameras. Today’s children are born, most of them watch close things, including reading, surfing the Internet and watching TV. Although people are born with their eyes in a hyperopia state, people always use their eyes close, and it will automatically put the focal length close. How can I get close? Only the eye shaft is lengthened. The normal ocular axis, that is, the anterior posterior diameter, is 24 mm. The eye axis is lengthened by 1mm, which is equivalent to 300 degree myopia. This is why there are more and more myopia now.
heredity is an important factor affecting vision. High myopia is very harmful. The common situation in life is that parents are short-sighted and children are easy to become short-sighted. How much does heredity affect children’s eyes?
and
play an important role in myopia, and environmental factors account for only 40%. Moreover, it is difficult to say whether a child has the genetic factor of myopia. Although parents do not wear glasses, their grandparents may be short-sighted, or this factor does not show up. In the understanding of heredity, most people can understand which part of a child looks like his father and which part looks like his mother. In fact, the same is true in the specific organ of the eye. The eye is a very delicate thing. Whether the individual structure of each part of it is normal and whether the collocation of each part is reasonable is also the basis for accepting the genetic influence of parents. Although this structural difference is very subtle, it does affect the eyes. Therefore, we can only make some efforts from the day after tomorrow. For example, I once suggested to some friends that marriage between two people with high myopia must be bad for future generations. Moreover, the harm of high myopia is also great.
in the research, it is difficult to find a sufficient sample to study whether myopia is inherited. At present, the largest study sample is hundreds of patients. Such research results show that myopia is inherited. This inheritance mostly refers to high myopia above 600 degrees. If both parents are highly myopic, the next generation is 100% likely to be myopic. If one of the parents isMeat must be nervous to adapt to it, which will cause eye fatigue.
some parents believe that children spend the most time in a day’s class at school. The main reason for children’s myopia is that there are too many courses in school and there is no way at home.
family is the key to prevent myopia.
homework should be shorter than one class. I always say this point to my parents. Because in class, unless in the exam, very few classes are writing. Most of the time, the children follow the teacher. The teacher will give lectures and write on the blackboard. Children don’t always stare at books. Eyes look far and close for a while, which is an active state. At home. Some good students don’t play until they finish their homework. It’s not good to always use your eyes at close range for one or two hours in a row, which makes your eye muscles tense. Therefore, it is unscientific for parents to ask their children to finish their homework before playing. 40 minutes at school is different from 40 minutes at home, so it should be less than 40 minutes.
children should rest for 10-15 minutes during homework. During the rest time, you should not watch TV or play computer. This can only increase the burden on the eyes. Help your parents do some housework, look away, or go out for a short walk. In this way, the eyes and brain rest. Parents should train their children to use their eyes for a short time to improve efficiency in a short time. Children should not be encouraged to have to finish their homework before they can do anything else. Children who come to our clinic often study for 2 hours before they finish their homework. Whether it is myopia or not, it is unreasonable to use your eyes like this. Moreover, the more children write, the closer they get, and parents don’t care about their children’s posture. Especially for some little girls, the characters are small and delicate, and the pencils are sharp. In fact, it doesn’t matter if you write bigger and thicker.
some parents are very worried when they see their children’s myopia. In the doctor’s opinion, what measures are the most effective? Parents should not buy things indiscriminately. They spend a lot of money. Their children are nervous about learning, which adds a lot of burden to their children. They specialize in making some instruments and spend time on physiotherapy. In fact, it’s better to let children play outdoors at this time. Playing normally and watching things from far to near are more useful than any valuable drugs and instruments.
