Investigation Report on Myopia 1 I. Reasons for Investigation
Two students in our class are particularly nearsighted, one is Chen Cheng, and the other is Zhao Wentao. Because of poor eyesight, it has brought a lot of trouble to their study and life. Chen Cheng can't take part in many activities on the physical education class because he is afraid of losing his glasses. Zhao Wentao has been sitting by the blackboard for a long time because of his poor eyesight. From the two of them, we can see the serious harm of myopia to our primary school students, which may bring a lot of inconvenience to their future life, study and work. Therefore, under the guidance of the teacher, our class conducted a more detailed investigation on students' myopia to see what factors are mainly involved in the decline of primary school students' eyesight, and hoped to provide some preventive measures for those students who are not nearsighted through this activity.
Second, the survey method
1, read relevant books to understand how ordinary people are nearsighted.
Ask the students to know how they are nearsighted.
3. Understand the myopia in the class through the questionnaire.
Third, the questionnaire
Questionnaire survey on myopia of primary school students
1. How is your eyesight now? ( )
A.5.0 or above b.4.5 to 4.9c.4.4 or below.
2. Are you nearsighted? Do you have glasses? ( )
A. Myopia without glasses B. Myopia with glasses C. Neither.
3. How old did you start to be nearsighted? ( )
A.6 years old and below b.7 to 9 years old c. 10 years old and above
4. What caused your myopia? ( )
A. I often play computer and watch TV. I have been reading for a long time. C. my posture is not correct. D. others.
5. Do you often do eye exercises? ( )
A.c. seldom D. never
6. Do you think myopia has an impact on your life and study? ( )
A. Great influence B. General influence C. Little influence D. No influence at all
Fourth, the investigation situation
There are 90 students in our class. Among them, there were 2 cases of severe myopia, 5 cases of poor eyesight requiring special care, 8 cases of mild myopia/kloc-0, and 65 cases of basically normal. Through various channels, our class made a serious investigation and analysis of the causes of myopia, which are summarized as follows.
1, I spent too much time surfing the Internet or watching TV, and my eyes were tired for a long time without rest.
2. Anti-fatigue eye drops and eye exercises have therapeutic effects on eyes, but they have not attracted the attention of students.
3. Unreasonable diet and long-term malnutrition due to snacks and partial eclipse.
4. Always write or do homework in dim light or strong light.
5. When reading or writing, don't pay attention to distance and posture.
6. Read in a rocking car or sleep on the sofa.
Although there are many people who are nearsighted, people who don't wear glasses account for a considerable proportion. This shows that students pay insufficient attention to myopia!
Suggestions on the investigation of verbs (abbreviation of verb)
Through the above investigation, it is found that although myopia is not too serious in our class, the above bad habits are common in our class, and almost every student has some different problems more or less. If it is not corrected in time, there will be more and more nearsighted students in our class. Therefore, I hope all the students in our class will pay attention to the following questions.
1. Insist on overlooking, doing eye exercises, and doing exercises between classes every day, and actively participate in cultural and sports activities.
2, develop a correct reading and writing posture, glasses and books should keep a distance of about 30 cm.
3. When reading and writing, the light should be moderate, neither too strong nor too dark, and the light should come from the front to avoid blocking the light with your hands.
4. Reading, surfing the Internet and watching TV should not be too long. Rest every 40-50 minutes 10- 15 minutes to prevent eye fatigue.
5. Don't read books and newspapers whose handwriting is too small or fuzzy.
6. Eat less snacks and pay attention to nutrition.
7. If you have vision problems, you should seek medical advice in time and wear appropriate glasses.
If all the students can do the above, their eyesight will get better and better. I hope every student in our class will take good care of his eyes.
Investigation report on myopia 2 I. Proposing the topic:
According to the survey, there are more than 5 million blind people in China, and the number of people with low vision is nearly10 million, especially children and adolescents, and the prevalence rate is extremely high. According to the latest data of the national student physical health survey, the incidence of myopia in primary school students, middle school students and high school students in China is 22.8%, 55.2% and 70.3% respectively. Why are so many people nearsighted? Is it just caused by bad eye habits? Myopia, is it related to age?
Two. Investigation method:
1. Consult related books to find out how ordinary people are nearsighted.
2. Investigate and ask classmates how they are nearsighted.
3. Find out how many people in the school are nearsighted through various channels.
4. Understand the possible complications caused by myopia.
Three. Investigation and data collation:
There are 56 people in the school who are nearsighted.
The myopia rate in China is close to 30%, 22.8% of primary school students suffer from myopia, and the myopia rate in junior high school has soared to 55.2%. 70.3% of high school students wear glasses, and the myopia rate of college students is as high as 80%.
There are many reasons for myopia. According to our guess, there are genetic factors, environmental factors, such as myopia caused by dust or sewage, individual factors, nutritional factors and sleep factors. The main reasons for students' myopia are doing homework too late, not getting enough sleep, watching TV and playing computer too much, and consuming a lot of German and protein.
All parts of the eyeball are small, the lens size is basically normal, and the anterior chamber is shallow. Hyperopia with microphthalmia. Pseudoophthalmia is characterized by small vision, red color, unclear edge, slight uplift, similar to ophthalmia or edema, but the corrected vision is normal or unchanged compared with the past, the visual field has not changed, and the fundus has not changed after long-term observation. The myopia rate of primary school students is very high now. Although myopia has some genetic factors, what is more important is the influence of external factors. At present, there is no more effective treatment except wearing glasses, and only permanent preventive measures can be taken. Although the high myopia rate of middle school students is related to the current education system, it is more due to the habit of using eyes. The key to prevent myopia is to develop good eye habits. According to the degree of myopia, the harm of myopia can be divided into four categories: mild, moderate, high and ultra-high myopia. Mild myopia is generally below 300 degrees. At this time, many myopia are pseudomyopia and mixed myopia. Parents should focus on preventing myopia from developing to a high level. Once moderate myopia is out of control, developing into high myopia (above 600 degrees) will bring a series of problems: inconvenience in daily life, limited entrance to school, joining the army and working, and eye diseases passed on to the next generation. Once high myopia is out of control, it will develop into ultra-high myopia (1000 degrees or more), and the retina may fall off at any time.
Four. conclusion
Through the analysis of the survey, I found that the causes of myopia are:
1. Watching TV too close;
2. Watching TV for too long;
3. The concentration of the TV screen is too deep;
4. Incorrect posture when writing homework;
5. Reading in the sun with too strong light;
6. Reading in dim light;
7. Sitting in front of the computer and TV for a long time;
8. unreasonable diet;
9. Reading in the carriage
10. Genetic factors
1 1. Not doing eye exercises seriously.
12. Generally speaking, most students have heavy homework burden, and the homework burden increases with the increase of grade.
13. No matter what grade you do your homework, you don't have a good rest for your eyes; The rest time at school once again shows a trend of decreasing with the increase of grade.
14. Anti-fatigue eye drops and eye exercises have therapeutic effects on eyes, but they have not attracted the attention of students.
15. Although there are many people who are nearsighted than those who are not nearsighted, people who don't wear glasses still account for a considerable proportion. This shows that students pay insufficient attention to myopia!
16. Some factors, such as incorrect posture and improper use of eyes, can be overcome and corrected as much as possible; For example, if the light is too dim or too strong, we can adjust it. We can try to avoid such things as improper protection and improper medication; . I made the following suggestions:
1, insist on overlooking, eye exercises and recess exercises every day, and actively participate in cultural and sports activities.
2. There should be enough light when studying, and the light should always be from the left. Don't read or write in weak light, dazzling sunlight and strong light.
3. Make a correct posture when reading. When reading or writing, keep your eyes one foot away from the book, your chest one punch away from the table and your hands one inch away from the pen tip. Don't sleep in bed or read while walking. Don't read and write at your desk.
4. Don't read while riding a bike or walking, and don't read while lying down. Do eye exercises twice a day.
5. Don't use your eyesight for a long time. Every 50 minutes of study, rest 10 minutes.
6. Don't watch TV too often for too long, and control it within 1 hour. Not too close. At least two meters apart.
7. Try to surf the Internet or watch other radioactive things as little as possible. Pay attention to the schedule and don't let your eyes be tired for a long time.
Remember the advice given by ophthalmologists: develop good eye habits: read books, surf the Internet and watch TV for no more than an hour, don't read books in too strong and dark light, be sure to pay attention to your writing posture, and it is very important to keep doing eye exercises.
In order to effectively prevent myopia and other eye diseases: first, we should develop good hygiene habits, eat reasonably, exercise and ensure physical and mental health; Second, we should correct bad habits and develop good eye hygiene; Third, we should regularly check our eyes in eye hospitals, especially patients with high myopia, and find eye diseases in time, so as to achieve early detection and early treatment. Eyes are the windows of the soul, so we must take good care of them. Judging from the number of myopia in China, there are a large number of myopia in China, and one third of them are primary and secondary school students, which fully shows that we primary and secondary school students are nearsighted only if we don't take care of our eyes. I hope all of us will take care of our eyes, let the figure of 300 million become history, and let more people open this "window" that is not nearsighted.

Investigation report on myopia 3 I. Proposing the subject
According to the survey, there are more than 5 million blind people in China, and the number of people with low vision is nearly10 million, especially children and adolescents, and the prevalence rate is extremely high. According to the latest data from the national student physical health survey, the incidence of myopia in primary school students, middle school students and high school students in China is 22.78%, 55.22% and 70.34% respectively. What's even more shocking is that a survey report says that there are more than 300,000 people who are blind due to high myopia in China. What should students do with myopia? Is it just caused by bad eye habits? In order to understand the myopia of primary school students and the related factors that cause myopia, I made a survey on some students in our school.
Second, the investigation and analysis:
Causes of eye myopia:
Most people usually don't pay attention to protecting their eyes, which leads to myopia. The results show that myopia is the adaptive change of human eyes to the contemporary environment, and its occurrence and development are closely related to the increase of eye activity environment and the imbalance of nutrient intake. Improper use of eyes and inattention to eye hygiene (such as watching TV and surfing the Internet for too long) are the main reasons for the sharp increase of myopia in modern children.
1, watching TV is too close, too long, and the picture density is too deep.
2. Incorrect posture when doing homework,
3. read in the sun with too strong or too weak light.
4. Don't do eye exercises seriously
Third, the survey results:
Through investigation, it is found that the myopia rate of middle school students is on the rise, but middle school students do not pay attention to this phenomenon. Some people even think that they are nearsighted, just wear a pair of glasses. It doesn't matter if you are nearsighted. Many people often blame it on bad eye habits, such as improper reading distance, too dim light, long-term eye use and so on. However, medical research in recent years shows that unbalanced diet, lack of sleep and noise are also important factors that induce myopia in adolescents.
Fourth, experience
In order to effectively prevent myopia and other eye diseases: first, we should develop good hygiene habits, eat reasonably, exercise and ensure physical and mental health; Second, we should correct bad habits and develop good eye hygiene; Third, we should regularly check our eyes in eye hospitals, especially patients with high myopia, and find eye diseases in time, so as to achieve early detection and early treatment. Vision is related to our life. We should take good care of our eyes and don't let us regret it later!
Myopia Survey Report 4 I. Asking questions
According to the latest data from the national student physical health survey, the incidence of myopia in primary school students, middle school students, high school students and college students in China is 22.78%, 55.22%, 70.34% and 80% respectively. Therefore, the prevention and treatment of myopia in children and adolescents has attracted more and more attention from students, parents and society. Why are there more and more nearsighted students? What should students do with myopia? In order to understand the myopia of primary school students and the related factors that cause myopia, our group investigated the myopia of our classmates.
Second, the survey method
1. Check the information on the Internet to find out what myopia is and the causes of myopia.
2. Investigate and visit students to understand their study and living habits.
3. Consult relevant books to understand the harm of myopia and its prevention methods.
4. Investigate the myopia status and myopia proportion of students in this class. Four. conclusion
1. The myopia rate of teenagers is increasing year by year, which is closely related to students' heavy study tasks and increasingly developed social life.
2, myopia can be prevented, to achieve the "five essentials" and "three don't":
"Five essentials":
(1) Develop good reading and writing habits;
(2) Reduce the continuous study time and do eye exercises every day;
(3) The learning environment should be reasonable and well lit;
(4) Pay attention to a balanced diet and do more outdoor activities;
(5) Check your eyesight regularly.
"Three Don 'ts":
(1) Don't get into the reading habit of lying, lying, walking and riding;
(2) Don't read in dim light or strong sunlight;
(3) Don't read with a flashlight under the covers.
Students, eyes are the windows to the soul. We should protect our eyes and make them shine forever!
First of all, the topic is put forward:
Many students in our class put on glasses one after another. How many people are nearsighted? Why are they nearsighted again? I made a survey.
Two. Investigation method:
1. Consult related books to find out how ordinary people are nearsighted.
2. Investigate and ask classmates how they are nearsighted.
Find out how many people in Class One are nearsighted through various channels.
4. Publish the questionnaire through the class blog.
Three. Investigation and data collation:
There are 1 1 people in my class.
The myopia rate in China is close to 30%, 22.7% of primary school students suffer from myopia, and the myopia rate in junior high school has soared to 55.8%. 70.3% of high school students wear glasses, and the myopia rate of college students is as high as 80%.

Investigation report on myopia. Ask questions.
Recently, students sitting in the back of our class can't see the blackboard, and it often happens that they leave their seats to look at the front blackboard. Of course, some students join in the fun, follow the crowd, and some are really nearsighted. I don't understand why there is so much myopia in my class, which used to be rare, so I decided to make an investigation.
Second, the survey method.
1, refer to the information provided on the Internet.
2. Read newspapers and periodicals.
3. Visit the students suffering from myopia in the class and find out the reasons.
Third, investigation and data collation.

Number of nearsighted students in primary and secondary schools
According to online data, the number of middle school students accounts for 55.22%, and the number of primary school students accounts for 22.78%.

Number of nearsighted people in China
According to statistics in recent years, the number of myopia in China is about 65.438+0.28672 billion, and its trend is still rising.
Ask a classmate
Causes of myopia
1. Genetic factors: High myopia is related to heredity, mostly autosomal recessive inheritance. So parents and children can't be nearsighted at the same time. Heredity is often influenced by objective environment and living conditions, which makes it mutate and increases the complexity of heredity.
2, environmental factors: environmental factors are mainly close work and bad working environment, you must turn on the light when writing at dusk, can not write in dark places.
3, nutrition and diet: when the body is weak or after a serious illness, the body's resistance decreases. If you use your eyes for a long time at this time, it is easy to be nearsighted. Children's myopia is related to the intake of sugar, protein and calcium and the lack of some trace elements (such as chromium, zinc, copper and sodium).
4. Regional differences and socio-economic factors, the prevalence of myopia among urban students is significantly higher than that of rural students, and this phenomenon is more obvious with age. Rural life is closer to nature, the air is fresh, and rural students have fewer opportunities to watch TV and use computers.
Observe for yourself
The number of nearsighted students in the class
It is observed that about 25% of the students in the class wear glasses.
Fourth, the conclusion.
The survey shows that China is pure myopia, with 65.438+0.3 billion people suffering from myopia. At present, the reason for myopia of most people in this class can basically be summarized as one, that is, surfing the Internet for a long time, not paying attention to eye protection, not doing eye exercises, and not dropping eye drops to relieve eye fatigue, which leads to a serious decline in vision. Therefore, I want to give you a suggestion here. I hope you can surf the Internet less, have a good sitting posture when writing and reading, read in a place with proper light, and give your eyes proper rest and protection. According to the doctor, now everyone is in the stage of physical development, and most myopia belongs to pseudomyopia. If you pay attention to eye care and treat it in time, you may recover. I hope everyone must pay attention to this problem and don't let their bright future be destroyed in their own hands.
