The classroom is not uniform, how to adjust the height of the desk to prevent myopia?

Introduction: Many people will find that myopia is gradually showing a trend of younger age, and there are more and more myopic people in the group of primary school students, which can't help but make people worry about their children's eye health. In the course of classroom learning, in fact, many school desks should be able to adjust the height freely.

After all, every child's body is different, and it is most comfortable to choose different heights to read a book. Classrooms are not uniform, so how can you adjust the height of your desks to prevent myopia?

In the previous school process, the height of the desks was the same height that could not be adjusted, which had different effects for students of different sizes. Some children are too tall or too short to write at their desks, which also leads to problems with their eyesight. However, there are many new types of desks that can be adjusted in height.

The choice of desk height should be kept 10 cm away from the student's eyes, and the teacher can adjust the height of the desk in the appropriate position to ensure that the student sits in a correct posture and does not bend over and hunch, so that the student can ensure the correct sitting posture and be able to read the words on the book clearly when writing and reading.

In fact, many areas have realized that the height of the desk in the classroom should not be uniform, but should be diversified according to the different regional characteristics and the different growth and development of students, so it is said that the height adjustment of desks and chairs in primary and secondary schools has been specially regulated, and the school is required to adjust the height of the desk once according to the height of the child in a semester, and it is best to make a personalized adjustment to the functional students, so as to prevent myopia for students. It is also included in the assessment index system.

The development of students should be individualized in terms of education and equipment, after all, every child is different. Only by respecting the differences in children's personalities can we truly help children grow up healthily, and the height of desks and chairs is actually one of the manifestations of this.

It is possible to adjust the height to about one meter, so that most children's height is acceptable, and the child will not lie on the table.

Adjusting the height to 1.2 meters is the most suitable for the child, and it is also necessary to let the child raise his head when writing homework.

I think we can raise the desks and chairs in the back so that the children sitting in the back can easily see the blackboard.

We can adjust the height of the desk according to our height, and we need to adjust our posture when we sit on a stool.

You can keep the height of the desk at the bottom of the blackboard consistent, so that you can prevent myopia, it is better for children's eyesight, and such desks are also particularly beautiful.

The height of the desk should be adjusted so that the distance between the plane and the child's eyes when sitting upright is more than 15cm, so as to effectively prevent myopia.

The height of the desk should be kept at 10 cm from the student's eyes to ensure that the student's sitting posture is not overturned, and the size of the desk should be noted.

Everyone now has higher requirements for children's things, and I also hope to buy good desks, which are practical and environmentally friendly, and children can use them safely and healthily and happily. Let me tell you what I think. Material:

Now more plastic is used, as well as wood, the advantage of plastic is that it is malleable, and it can be designed with a variety of shapes and colors, children prefer but the practicality is not as good as wood, and parents will be more inclined to wood. If you are wood, you can look at the grade of the desk with solid wood or composite board, but one thing to pay attention to is the paint problem, formaldehyde is definitely not good for children. Design Structure:

Because the child is still growing up so the height changes greatly, the height of the desk and the table top should be designed to be adjusted to meet the needs of different babies, and now many children's desks will be designed with an inclined plane is also to allow children to not overbend the spine when writing homework.

The desk also needs to have a certain storage function, you need to design a small bookshelf to put the books you read daily, put a few small drawers, you can put some learning tools and the like. Another is that the desk is generally equipped with a desk lamp, and it is necessary to design the position of the desk lamp, and if it is placed directly on the desktop, it is necessary to design the inlet of the power supply to facilitate power. Style design:

China's Ministry of Health has issued a national standard for the hygiene of school desks and chairs, which determines the height standards for desks and chairs used by nine types of students of different heights. For example, if a student is under 119 cm tall, the height of the desk should be 52 cm, the height of the empty space under the desk should be 40 cm, and the height of the chair should be 29 cm.

Students who are between 143 and 175 cm tall should be 67 cm tall on desks, 55 cm in the open space under the desks and 38 cm in chairs. Moreover, according to the regulations, the form of desks and chairs used in primary and secondary schools can be optional, but the main dimensions of the table height, the height of the empty area under the desk and the height of the chair must meet the national standards. There's no grade-level like you're talking about, and a lot of schools don't meet the standards right now.

For saying that the classroom is not uniform, it is beautiful, and I want to adjust the height of the desk to prevent myopia. First of all, the teacher should adjust according to the student's own height and the degree of myopia of the eyes.

We must use scientific standards to adjust the height of the desk, and the school must adjust the height of the desk according to the height of the child every semester, which will prevent myopia.

If you want to adjust the height of the desk to prevent myopia, I think it is better to set it according to the height of the student, and it can play a role in preventing myopia.

The class is chaotic and not uniform. The height of the benches can be flexibly adjusted according to the height of the students, reflecting the concept of student-centered and personalized education. During the term term, the height of the benches and chairs should be adjusted individually to ensure that each child has a table and chair that matches their height.

Use the tallest chair possible. After that, place a foot pad on your feet, keeping your thighs and calves vertical. When the table or chair does not match its height, it is one of the factors that contribute to myopia in children.

Currently, most benches and chairs have automatic height adjustment. However, the class layout in developed countries in Europe and the United States is rarely uniform. Some are located in different regions, while others are beautiful due to their location.

The height of the desk and chair is flexibly adjusted according to the height of the student, which reflects the height of the student. If the height of the benches used for writing matches their height is one of the factors for myopia in children, then when the tasks of the same class are too short, a cushion should be placed on the table or chair.

What you should pay attention to is setting up lights, benches, and chairs in your classroom to reduce the risk of myopia. The distance between the benches should be increased. The height of benches and chairs should be adjusted individually every six months to protect children's eyesight and prevent myopia.

The issue of the height of the bench resonated with netizens. How do I adjust the height of the bench? Children are growing and developing, and their height changes from year to year.

If adjusted, the student's sitting posture will be non-standard, resulting in curvature of the spine, hump, and tilt of the shoulders. The net distance between the end of the desk and the wall must not be less than.

In the new period, pay attention to increasing the distance between benches and chairs. The height of student benches and chairs is individually adjusted each semester. In Beijing, more than 40% of primary and secondary school students have never set the height of benches, which is inappropriate.

However, primary and secondary education in developed countries in Europe and the United States is rarely uniform. In addition to adjusting the height of the benches, the school also replaced the light fixtures to protect the eyes. At the same time, reduce the cost of learning.

Be sure to pay attention to the height of the desk, and then students should also develop a good sitting habit, and be sure to pay attention to the distance between their eyes and books when writing homework, so as to prevent myopia.

Try to choose the height of the desk between 80 cm and 90 cm, because this can play a good role and avoid serious effects on the child's body, or other injuries.

Adjust a centered position, preferably to a height of meters, is the most appropriate, so that the child will not be short-sighted when doing homework.

At present, everyone's food regulations for children are very high, and the desks are also looking forward to buying better, looking forward to using them for environmental protection, and children are happy to use them for health and safety. Let me share my opinion. Material:

Nowadays, more plastic is used, there are also wood, the benefit of plastic is that it is malleable, can be designed and coded a variety of shades, children are very fond of but the applicability is not as good as wood, parents will be more inclined to wood.

The wood has to be solid wood or sandwich panel to look at the desk level, but one thing to pay attention to is the paint problem, indoor formaldehyde is definitely not good for children. Design structure: because the child is still in the development period, so the height of the desk has changed, the height of the desk in the design situation also needs to be designed to be able to adjust to meet the requirements of different babies, and now many baby's desks will be designed as a ramp is also because the child is not easy to bend the spine too much in the case of homework.

The desk also needs to have a certain role in placing things, and a small bookcase must be designed to be placed in the books that are read daily, and a number of small drawer cabinets can be placed to put some teaching tools and the like. There is also a desk is generally equipped with a small desk lamp, must be designed to place the small desk lamp part, if immediately put on the desktop to design the switch power supply of the three-phase five-wire port, convenient plug-in. Style design:

Children love to be lively and cute, you can make the book designed to look like an animal, then children must love it, and the color also needs to be bright colors, which is very easy to lead to children's hobbies.

In China, the Ministry of Health of the People's Republic of China has announced the national industry standard for the environmental sanitation of desks and chairs for students in colleges and universities, and clarified the height specifications for desks, chairs and benches used by nine types of students of different heights. For example, if the student is less than 119 cm, the height of the desk and chair should be 52 cm, the height of the empty area under the table should be 40 cm, and the height of the chair should be 29 cm.

Students who are between 143 and 175 cm tall should be 67 cm tall with desks and chairs, 55 cm from the empty area under the desk, and 38 cm from the top of the chairs. And according to the requirements, the types of student desks and chairs used in primary and secondary schools can be selected at will, but the key specifications of table height, height of the empty area under the table and height of the chair must meet the national industry standards. There's no class-based as you say, and many colleges and universities don't meet the rules these days.

It should be arranged from low to high from front to back, which is better for the child and can also prevent the child in front of him from blocking the student behind.

It has a lot to do with the child's height, and it is best to choose an adjustable desk according to the height, so as not to affect the child's eyesight.

At this time, it should be based on the height and weight of the child, and then the country has also issued corresponding standards, and it is also necessary to make relevant plans, and it should be adjusted once every semester.

There is an ancient poem that describes the pain of myopia! In his early years, he was tired of reading books, and in his later years, he was sad and cried. I don't know if the eye damage is self-inflicted, and the disease becomes a prescription for what I want. The night seems to be as if the lights are about to go out, and the long suspicion mirror is not polished. There are thousands of medicines that can't cure it, but you should close your eyes and learn from Toutuo.

This poem describes some of the feelings and pain of myopia, in fact, I have no power to qualify for this issue, because I am myopic for more than 300 degrees, and I usually don't wear glasses, because I am afraid of affecting my handsomeness (so stinky and shameless), but I must endure a lot of pain while being handsome. There is a very good sentence that is also very good.

The farthest distance in the world is not life and death. Instead, you walked towards me, but I couldn't see you clearly, so in order not to let everyone be like me, and not to let the glasses affect everyone's handsomeness and beauty, I put forward some small suggestions

1.Develop good eye hygiene habits, write in a correct posture, stay one foot away from the book, do not read on your stomach, lie down, do not read in a bright or dim place, do not read for too long, let your eyes rest for a while every 50 minutes or so, and look into the distance.

2.It is not advisable to watch TV for a long time, and can not play video games for a long time. Many children simply forget the existence of time after playing addiction, which is very harmful.

3.Doing eye exercises is very important to eliminate eye fatigue and protect eyesight, and it is also a daily protection that each of us can do.

Once or twice, you can do eye exercises whenever you read a book for a long time or feel visual fatigue.

4.Participate in outdoor activities, see more trees, flowers and other green plants, and often look far away from a wide field of vision.

5.Check your eyesight regularly, diagnose and treat it in time if you find that your vision is declining, and re-optometry and glasses when your myopia deepens.

That's what I thought of, and in the end, I hope that people who are as short-sighted as me will get rid of the shackles of glasses as soon as possible and be able to see everything beautiful in the world! People who are not myopic must develop good habits, take care of their eyes, take care of themselves, and hate it too late until they are myopia!
