The survey report on middle school students' myopia can be described from three aspects. First of all, it can describe the purpose of the investigation report. Secondly, it describes the specific process and data of the survey. Thirdly, it describes the results and analysis of the investigation report.
Investigation report on myopia of middle school students;
Background: If you pay attention to the people around you, you will find that many people need "eye assistants". Teenagers, in particular, are at the peak of eye use, and if they don't pay attention to eye protection, they will be seriously injured. Therefore, the problem of myopia is becoming more and more serious.
At present, there are more than 300 million myopia patients in China, accounting for 1/3 of the global myopia patients. The myopia rate of China students has risen from the fourth place in the world after 1.998 to the second place, second only to Japan, which is the largest country in myopia. Among them, the myopia rate of middle school students has reached 34.6%, the myopia rate of high school students has reached 70%, and the number of teenagers blinded by high myopia in China has reached 300,000.
Investigation shows that the incidence of myopia increased from about 15% in the 1970s to about 55% or even 80% in the late 1990s. The incidence of myopia in China is rising rapidly, and it is time for the whole society to pay attention to it and take measures.
Team members: Luo Xing, Zuo Ping, Guo, Su Hongyu, Fang Jingchao, Qin Zhen, Sheng Langying.
Activity time: 65438+February15-65438+1October 3rd.
Activities: streets, schools, optical shops,
Survey methods: Internet information search, questionnaire survey and eye shop survey.
Question: According to the data of online survey, the incidence of myopia among teenagers in China has reached more than 30%, that is to say, more than three children in 10 are nearsighted. Parents and teachers have become accustomed to primary school students wearing glasses, and it is not uncommon for children in kindergarten classes to wear glasses. Among them, the age of high school reaches about 50%. So, why is the proportion of myopia among middle school students so high? Do we have any questions about this? Is it too much pressure to study? Still a matter of habit? Or other factors. We investigated this: (insert survey)
Through visits to major optical shops, we know that myopia is showing the following characteristics: First, the incidence rate is rising all the way; The second is to develop towards younger age; Third, the causes of myopia are more and more diverse. Every holiday, eye shops are "prosperous". Why? It is not difficult to see from the survey results that watching TV and playing computer games have become the most important "killers".
The following is our discussion and research, and it is concluded that the onset of juvenile myopia involves five pathogenic factors:
1, poor learning environment;
2. Bad eye habits;
3. Genetic history of juvenile myopia;
4. Less outdoor activities and physical exercise;
5. The average study time is long every day.
6. Watching TV, playing computer or video games for too long;
Among them, poor learning environment, playing games and bad eye habits are significantly related to the onset of myopia in adolescents. With the development of society, article 6 has attracted more and more attention. Watching TV and playing computer should have an effect on myopia. Is the key time too long?
Solve the problem:
With the discovery and gradual deepening of the problem, our team members summarized the following solutions through discussion and analysis:
1. At present, the classroom design structure of many schools is unreasonable, the lighting does not meet the requirements, the number of students in the classroom is seriously exceeding the standard, and the height and spacing of desks and chairs are not suitable for the height of students. Therefore, schools should vigorously strengthen the setting and improvement of students' learning infrastructure to meet the requirements of health and hygiene standards.
2. In students' homes, parents should also create a good learning environment for students, so that their lighting, desks and chairs meet the health and hygiene standards.
3. Strengthen school health education, vigorously publicize students' eye health knowledge, change bad health behaviors, develop good eye health habits, improve self-care ability and protect eyesight.
4. Teachers and parents should advise students to watch less TV, especially to explain the harm of watching TV at close range to their eyesight; Don't read in too dark or too strong light; Don't read when riding a bike, walking or staying in bed. It is also necessary to help students correct incorrect reading and writing postures and bad eye hygiene habits. Students with genetic history should protect their eyesight seriously and resolutely correct the factors and habits that harm their eyesight.
5. Adhere to the promotion and popularization of eye exercises, so that students can study and do well correctly, consciously and conscientiously, and check their eyesight regularly to achieve early detection and correction.
6. When myopia students need glasses, they should go to the medical department for consultation, optometry and glasses. They must not wear short-sighted glasses in street optical shops at will.
7. Add foods rich in vitamins A, D and B2 to students' diet. Students should be educated to arrange their study time reasonably, and the study time should not be too long. They should consciously rest their eyes between studies, so as to combine work and rest, protect their eyesight and improve their learning efficiency.
8. Watch TV and play computer for no more than 40~50 minutes at a time. Take a rest in the middle, look at the distance with your eyes, reduce eye fatigue and avoid deepening myopia.
We screened this questionnaire about this survey activity from the Internet.

No, eight people-
I don't know. 15 people-
Yes -52 people
22 nd person
Analysis:
According to the questionnaire survey. The main factors of middle school and myopia are as follows:
First, do not pay attention to eye hygiene. Eyes are very picky, and if you don't pay attention, you will get various eye diseases. Among them, myopia is the most common. In order to protect your eyes, you must pay attention to eye hygiene, such as: don't rub your eyes, don't drop foreign objects into your eyes, and don't smear irritating substances around your eyes? But now some middle school students neglect eye hygiene for various reasons, making their eyes nearsighted.
Second, watch TV, surf the Internet and read literature books over time. Many students are nearsighted because of overwork, but some students are nearsighted not because time is short, but because they have plenty of time to pass the time. So they began to watch TV, surf the Internet and read novels, and over time they became fascinated. As we all know, the radiation of TV and computer will stimulate the retina in your eyes, and reading books for too long will make you tired. After a long time, you will naturally be nearsighted.
2. The following information was downloaded from the Internet:
According to the eighth edition of China Education News on March 2, 2005, almost 8 out of every 10 middle school students in Chengdu are nearsighted (including "pseudomyopia" without glasses and "low vision" in ophthalmology), and quite a few of them are developing to high myopia.
A middle school in Yulin investigated the eyesight status of thousands of students from Grade One to Grade Three, and got the following results: myopia in Grade Two accounts for 20%, myopia in Grade Three accounts for 40%, myopia in Grade Two accounts for 50% and myopia in Grade Three accounts for 70%. The average binocular vision of these people who need glasses is equal to or lower than 0.6. Zhang, a student in grade 1, said that when he was in grade one, his myopia was less than 100. However, with the aggravation of learning tasks, he spends less and less time playing outside class and reading more and more every day. As a result, he used his eyes for a long time and his vision became blurred. Now he wears glasses of nearly 500 degrees, which makes him feel very inconvenient. Zhang, who lives in Changmao community, told us that he is not nearsighted and has become a "national treasure" in his class. Everyone envies him for having a pair of normal eyes.
3. Optical shop survey
We took to the streets and conducted an in-depth investigation in major optical shops. We asked them about the problems we discussed and learned about the current social reality. Through careful interviews, we know that the number of middle school students who come to wear glasses accounts for about 3/5 of the total number of opticians. This fully shows that we should attach great importance to this problem and prevent it from deteriorating again and again. Perhaps, things are not as alarmist as I said, but small worries will eventually become big worries, just like ". So first of all, beware of procrastination.
Now they are curious, so they don't pay attention to the behavior that will lead to myopia (even if they know it), and generally think it's no big deal. Because of this, myopia took advantage of it and began to attack people's eyes crazily, which led them to become glasses lovers.
About the prevention and treatment of myopia:
1. Eat more fresh vegetables, fruits, bean products, kelp, etc. Eat less candy and never be partial to food. 2. Various forms of overlooking, such as recognizing the stars in the sky at night and overlooking trees or buildings in the distance. Don't use pencils that are too light, too short and too sharp. 4. The mixed light of incandescent lamp and fluorescent lamp can be used for lighting, and the light should be on the left side or the left front side. 5. Pay attention to eye hygiene, and don't read in bed, in a moving car, while walking, in the sun or in the dark. When watching TV, people are 2.5-3 meters away from the TV; Television is slightly lower than the apparent horizon; Keep your eyes closed for a few minutes after watching 1 hour continuously; If you watch for 4 hours without rest, your vision will drop by 0.2. In a word, we must overcome the problem of using our eyes for a long time and at close range to prevent myopia.
Picky food and partial eclipse will make the nutrition supply of children's eye development insufficient. Therefore, to prevent myopia, children's recipes should be diversified, and attention should be paid to the collocation and thickness of meat and vegetables to ensure adequate supply of eye nutrition. You can eat more foods such as longan, yam, spinach, millet, corn, etc. At the same time, mulberries, black beans, red dates, walnuts and other foods can play a role in nourishing the heart, calming the nerves and improving eyesight. Furthermore, protein, calcium, phosphorus and vitamins should be supplemented. It is also important to supplement zinc, chromium and other elements, such as soybeans, almonds, seaweed, kelp, mutton, yellow croaker, milk powder and so on. Beef, grain, meat, liver and other foods are rich in chromium.
Six points of myopia prevention and treatment
① Use eyes to prevent fatigue: such as reading for a long time, doing homework, watching computer, lying down or reading in dark light. 2 Reasonable glasses: glasses should be worn for myopia above 50 degrees, only when looking at a distance below 250 degrees, and often when looking at a distance above 250 degrees. It is best to add virtual focal lenses.
③ Wear virtual focus glasses: Primary and middle school students should use virtual focus myopia control glasses as soon as possible to minimize the development of myopia caused by reading, homework or playing computer.
④ Best prevention and treatment of amblyopia astigmatism: amblyopia should be cured as soon as possible, and astigmatism above 100 degree should be corrected frequently with glasses. ⑤ Surgery to prevent the development of myopia:/kloc-children under 0/0 should have posterior scleral reinforcement as soon as possible if the myopia degree reaches more than 450 degrees.
⑥ Laser surgery: After 18 years old, when myopia is stable and does not develop, excimer laser can be used to eliminate myopia and take off glasses.
In addition, children should play less video games, watch less TV as far as possible, do more outdoor activities, strengthen exercise, go to bed early and get up early, correct partial eclipse, make reasonable lighting, check their eyesight in time, and find and treat them early, which is also of great significance to prevent myopia.
"Three-character Classics" for Preventing Myopia
Myopia, not far to see, inconvenient to do things, not difficult to prevent;
Do it seriously. Don't look at the dim light, it will hurt your eyes and damage your eyesight.
Warm up the homework for an hour, stop and watch it again. Sit up straight when reading;
Eyes are a foot away from the book. Don't read in the sun; The light is too strong and my eyes are blurred.
Here's how we felt afterwards:
At present, the myopia rate of middle school students in China is increasing year by year, and it is time for the society to pay attention to it and take measures. In the interview, I learned that middle school students don't pay attention to myopia now, so that they don't know much about myopia. Most middle school students are curious about myopia, and a few even yearn for their own myopia. This is the common psychology of middle school students for myopia. We also have such examples around us. Some students just think it's fun at first and pretend to be cool with glasses. Finally, they really couldn't live without their glasses, and then they began to regret it. It's really a long-term regret! This may be one of the main reasons for myopia!
Investigation report on myopia of middle school students II:
First, ask questions.
In today's talented society, it is extremely important to have a healthy body. With the development of big cities, there are many high-rise buildings and streets crossing everywhere, and people have less and less opportunities to get close to nature. People are very busy and seldom stop to have a rest. Middle school students' myopia is becoming more and more serious. In the class, all the students wear glasses. Aiming at the problem of middle school students' eyesight, I conducted a vision survey on middle school students in Class 6, Grade 2, Yucai Middle School, Xingtai City, Hebei Province.
Second, the purpose of the investigation
Middle school students' eyesight survey made them realize the seriousness of myopia. Put forward an initiative to convey the harm of myopia to students and make them realize the importance of protecting their eyes.
Third, the investigation process.
1. Literature research methods
(1) What is myopia?
We all know that the basic structure of the eye is composed of cornea, pupil, lens, retina and iris. The tube images on the retina through the lens, and the information is transmitted to the brain through the optic nerve to produce vision, so that people can see objects clearly. This is the working principle of the eyes.
Myopia is a kind of visual defect, which can see clearly what is near and not what is far away. Myopia is caused by the fact that the lens of the eye is far away from the retina or the refractive power of the lens is strong, so that the image entering the eyeball falls in front of the retina instead of directly on the retina.
Myopia needs to wear concave lens: because concave lens has divergent effect on light, the light originally focused on retina diverges and then focuses on retina.
(2) Causes of poor eyesight of junior middle school students.
First of all, the environment is the main factor of myopia. Excessive use of eyes fatigue, not using eyes, makes the adjustment function of many teenagers gradually decline and be destroyed. The problem now is that students' desks and chairs are not standardized and are not configured according to grade and individual differences, which is not convenient for students to develop sitting posture. Poor lighting in the classroom can also make students nearsighted. In addition, long-term exposure to fluorescent objects, such as televisions and computers, leads to the decline of students' eyesight. Therefore, the poor learning environment has seriously affected students' health.
Secondly, if you don't take part in physical exercise, you can't be poor. According to the information searched online, the myopia rate of sports students is less than that of ordinary colleges and universities, only four points. On the one hand, students majoring in physical education have less academic burden, on the other hand, they love sports and are healthy. Girls in ordinary schools do not like sports more than boys, and the myopia rate of girls is higher than that of boys.
Thirdly, unscientific eating habits can also lead to myopia. Clinical data and animal experiments show that myopia is related to trace elements such as calcium and chromium. Sweet food is acidic food, which will consume calcium in the body, increase blood sugar and crystal osmotic pressure, and is another bane of myopia.
2. Make an interview with the "Eyesight Optical Shop" around Yucai Middle School.
Q: Who are most of the people who come to match myopia glasses?
A: The largest number is junior high school students.
Q: How nearsighted are the students?
A: Most of them are at 100-200 degrees.
Q: Is myopia getting deeper and deeper without glasses?
A: It depends on the guarantee. Some students' true myopia is problematic as long as they are well protected and prevented.
However, myopia has exceeded 200 degrees. If you don't wear glasses, you will lose your myopia in order to study, which is very bad. In short, it is very important to protect your eyes regardless of myopia or not.
Q: What causes myopia?
A: The reasons for middle school students' myopia are:
1, reading and writing posture is not;
2. Do not pay attention to the intensity of light when reading and writing;
3. The life and study system is not perfect;
4. Congenital factors.
Q: What is the common sense of wearing glasses?
A: mydriasis optometry should be done before glasses, and it is diagnosed as myopia; The glasses you wear should be glasses with the right degree, not too deep or too shallow; After wearing glasses, you should pay attention to eye hygiene to prevent it. Check your eyesight. If your eyesight drops, you need to get glasses again.
Q: Can you give some advice to middle school students for myopia?
Answer: use eye hygiene; If you have myopia, you need glasses; See more green and adjust your eyes from afar. To prevent myopia, we must finally achieve "three essentials" and "four don't look".
3. Distribute questionnaires and simply interview students.
In order to further understand the eyesight status of junior middle school students, a questionnaire survey and a brief interview were conducted among 65 middle school students in Class 6, Grade 2, Yucai Middle School, Xingtai City. The details of the questionnaire are as follows:
Fourth, the analysis of the survey results.
After my questionnaire survey, the results are as follows:
According to statistics, 63.08% of the students in this survey are nearsighted, accounting for more than half of the total number.
2. Years of myopia
The information in the figure accounts for 23. 1% and 17.2% respectively. What does this mean? First, the rise of junior high school has brought serious unhealthy eyes to schools and students; On the other hand, students develop habits with their eyes consciously and healthily. Generally speaking, schools and students are not aware of healthy eyes.
23% meat. Eating habits are the direct cause of myopia, but they are also the inducement. For example, carotene, vitamins A and B2 can make eyes tired easily, which leads to myopia. Eat more foods containing vitamins A, B2 and carotene, such as milk, animal liver, eggs, peanuts, carrots and vegetables. But when reading, I don't mean the category of books, but the posture of reading should follow the principle of "two wants and two don't want". The so-called "two musts" means that the distance between your eyes and the book should be one foot, you should keep reading for about an hour, you should take a break and look far away, while the "two musts" means that you should not read in dim light and sunshine, and you should not lie in bed. However, the data shows that 46.3% of the students surveyed usually read books that are closer to writing or lie in bed. Although the effort is good, it is a pity that the result will damage the eyes.
The number of students is only nearly 9%, which is quite impressive.
Yes, not to mention academic performance, it is easy to be nearsighted just by the radiation of TV and computer, and students watch TV and play computer games, and more than 70% watch TV for two hours. If they give their eyes too much burden and don't rest, myopia is only a matter of time.
Verb (abbreviation of verb) abstract
Through this activity, I learned about the myopia of middle school students. Generally speaking, I am not optimistic. I have a deeper understanding of the causes of myopia and know how to prevent myopia.
How to make teenagers use their eyes reasonably? By investigating the proportion and causes of middle school students' myopia, teenagers can understand the harm of myopia, as well as their awareness of self-health and eye use.
In this regard, I sincerely give the following suggestions, hoping that everyone can protect their eyesight and prevent the expansion of the myopia team.
1. Strengthen eye health education
According to the survey, some middle school students' eyesight drops when their posture is not close to the distance, which shows that students do not correctly understand and attach importance to the significance of posture and proper distance in protecting their eyesight in daily life. This requires
Our teachers educate and emphasize students' behaviors and habits in teaching and daily life, as well as students' awareness of protecting their eyes. We believe that eye hygiene education should start from primary school, and students should form the habit of "three wants and two don't want" as soon as they go to school, so that students can get used to requirements from an early age.
2. Pay attention to eye rest.
The survey shows that long study time is the main reason for the decline of vision. Nowadays, the competition among college entrance examination, senior high school entrance examination and junior high school is becoming more and more fierce. Pursuing the enrollment rate by extending the time and asking questions will reduce students' eyesight, cause irreparable losses, reduce students' physique and seriously hinder their study. Therefore, the teaching of all subjects has the responsibility to help students get rid of problems, reduce their learning intensity and give them time to rest.
3. Take active measures to maintain and correct.
Eye exercises have been accepted by most students. Schools should increase the number of unified exercises under appropriate circumstances, and teachers should seriously guide and correct mistakes so that they can play a real protective role. Now some middle school students' myopia is only pseudomyopia. If they pay attention to protection, they can recover, while others have become truly nearsighted. At this time, they should wear appropriate glasses to correct it, so as to ensure that their eyesight will no longer decline and they can't cope casually. Therefore, myopia patients should go to the hospital to get glasses.
Reasonable diet
Protein in diet, reducing the supply of carbohydrates, can reduce or prevent the increase of myopia in adolescents with genetic background. So in order to avoid myopia, eat less candy and high-sugar food. Too much sugar will produce a lot of acidic substances in the blood. The acid and salt in the body are calcium phase, which will make the eye wall tough, make the eye axis easy to elongate and promote myopia and development. On the surface, protein, calcium, phosphorus, carrots, bean sprouts, oranges, oranges, red dates and other fruits and vegetables can be supplemented to prevent myopia.
5. Do a good job of publicity
Schools can publicize the importance of protecting eyesight through blackboard newspapers and lectures, introduce the methods of protecting eyesight, and strengthen the awareness of protection.
6. Watch less TV, play more computers and video games, and get in touch with nature.
From the survey, we know that the number of nearsighted people in da li is far greater than that in Chaoyang. Why? There are some important factors surrounding the environment. Chaoyang city is surrounded by mountains and seas, with green mountains and green waters in rural areas. Many students can walk around after studying, look at the surrounding mountains and green waters and relax, which will also help their eyes more than contacting nature. However, in the big city, life is rich, and every household has a TV, a computer and a game machine. Students are addicted to TV, computer or video games after school, which is very serious for their eyesight.
At this point, the report finally came to an end, and a big stone in my heart was put down. In the joke, I really learned a lot of knowledge. More importantly, I learned the thinking method of analyzing problems. In the process of collecting information, I learned to work together and help each other, and formed a deep friendship? Make a lot of money from everything.
There were many episodes in the whole process, and the tastes didn't fit together, but I was really happy. This is an experience, an experience and a wealth for me. Create a society and love life. The exercise you need and the quality it can achieve will benefit you for life.
In this survey, we all know that poor eyesight will bring a lot of inconvenience. The eyes are the most important sensory organs. Everyone's experience and knowledge are mostly obtained through vision. It is the interest of personal health, safety and life. Hinder learning activities and show vision care's sexuality. Eyes are equal to wealth for everyone, so take good care of your eyes.
Eyes are the eternal window of mankind-your wealth and mine. Friend, please cherish your eyes!
1. Are you nearsighted? A is B, isn't it?
The percentage of myopia in the survey population is now a topic of concern to all students. According to statistics, 5 1 students are nearsighted in this survey, accounting for about two points. Among all the people surveyed, the number of nearsightedness in da li is far greater than that in Chaoyang. The number of myopia in Chaoyang only accounts for three points.
2. When did you become nearsighted? A. Primary school B. Junior high school C. Before going to school
From the above table, it can be concluded that nearly 55% of the students are nearsighted from junior high school, and nearly 30% from primary school.
What does this mean? First, the rise of junior high school has brought serious unhealthy eyes to schools and students; On the other hand, students develop habits with their eyes consciously and healthily. Generally speaking, schools and students are not aware of healthy eyes.
3. What is the ratio of vegetables to meat?
A. vegetables = meat
From the above table, 36% people eat less vegetables than meat. Vegetables account for 465,438+0% of meat, but vegetables account for 23% of meat. Eating habits are the direct cause of myopia, but they are also the inducement. For example, carotene, vitamins A and B2 can make eyes tired easily, which leads to myopia. Eat more foods containing vitamins A, B2 and carotene, such as milk, animal liver, eggs, peanuts, carrots and vegetables.
4. What is your reading posture?
A is closer to the text, B is farther from the text, C is lying in bed, D is watching E on the road, and others.
In addition, in the interview, I know that there are 24 people reading books during the holidays. Reading is not a bad thing, but reading also means reading. What I mean here is not the category of books, but the posture of reading. We should follow the principle of "two wants and two don't want". The so-called "two essentials" means that the distance between the eyes and the book should be one foot, reading for about an hour continuously, taking a break and looking far away for a while, but "two necessities". However, the data shows that 64% of the students in this school usually read books closer to writing and lie in bed. It's good to study hard, but it's a pity if your grades hurt your eyes.
5. What is the average myopia degree of your eyes now?
A. 100 degrees
As can be seen from the above table, 100 ~ 300 degrees of pseudomyopia are all students, and only nearly 9% of students with 500 degrees of myopia are still considerable.
6. What do you usually like to do?
A. Watching TV B. Reading C. Playing computer games D. Sports E.
According to the survey and analysis, about 22% students watch TV and play computer games during holidays, not to mention the impact on their academic performance. It is only a matter of time before they are nearsighted. More than 70% students watch TV for two hours while watching TV and playing computer games. If they give their eyes too much burden and don't rest, myopia is only a matter of time.
What does this mean? First, the rise of junior high school has brought serious unhealthy eyes to schools and students; On the other hand, students develop habits with their eyes consciously and healthily. Generally speaking, schools and students are not aware of healthy eyes.
This activity shows that the situation of middle school students' myopia is generally not optimistic, and they have a deeper understanding of the causes of myopia and know how to prevent myopia.
How to make teenagers use their eyes reasonably? By investigating the causes of myopia among middle school students, teenagers can understand the harm of myopia, as well as their own health and awareness of using their eyes.
In this regard, I sincerely give suggestions, hoping that everyone's eyesight will be protected and the myopia team will be prevented.
1, eye health education
According to the survey, a middle school student's eyesight drops when his posture is not close, which shows that students have a good understanding of the significance of posture and distance in protecting their eyesight in daily life. This requires teachers to educate and emphasize students' habits and students' awareness of protecting their eyes in teaching and daily life. Eye hygiene education should start from primary school, and form the habit of "three wants and two don't want" as soon as you go to school, so that students can get used to requirements from an early age.
2. Pay attention to other parts of your eyes
According to the survey, studying for a long time is the main reason for the decline of vision. Nowadays, the competition among college entrance examination, senior high school entrance examination and junior high school is becoming more and more fierce. Pursuing the enrollment rate by prolonging questions will make students' eyesight decline, which will never make up for the loss, and will also make students' physique decline, which will seriously hinder their study. The teaching of all subjects has the responsibility to help students get rid of problems, reduce their study intensity and let them pay attention to rest.
3. Methods and amendments
Most students have used eye exercises, and schools should also do them under certain circumstances. Teachers should give guidance, correct mistakes and make them truly protective. One of middle school students' myopia is pseudomyopia. If they can recover after careful protection, it will become true myopia. At this time, they should wear appropriate glasses to correct and cope with the decline of vision casually. People with myopia should go to the hospital to get glasses.
Step 4 prescribe diet
Protein in the diet, the supply of carbohydrates, can make teenagers with genetic background and myopia or stop myopia. For myopia, eat less candy and high-sugar foods. Too much sugar will produce acidic substances in the blood. Both acid and salt in the body are calcium phase, which leads to blood calcium, that is,
