Investigation report on myopia 1
With the popularization of computers, many children suffer from myopia. Therefore, parents and friends are more concerned about this issue and worry about their children's health. To tell the truth, I have myopia, too. There are many students suffering from myopia around me, so I really want to find out why they are nearsighted. So, I investigated the causes of myopia in primary school students.
I. Purpose of the investigation
1. Investigate students' myopia, understand the causes of myopia, the influence of myopia on individuals and its prevention and treatment programs.
2. Through the investigation of myopia, people's awareness of preventing myopia can be improved, thus reducing the myopia rate.
Second, the practice process
1. I looked up information on the Internet to find out how ordinary people get myopia.
2. Read the relevant contents about myopia in recent newspapers and periodicals, and deeply discuss the causes, harm and prevention of myopia.
3. I called my classmates and friends with myopia and asked them how they were nearsighted and the inconvenience caused by myopia.
4. Go to Chenzhou Children's Hospital to consult the attending physician about the causes and preventive measures of myopia in primary school students.
Third, the survey data and analysis
In my investigation, I found that 12- 18-year-old myopia developed rapidly. The incidence of myopia was 20. 13% for primary school students, 56. 12% for middle school students and 23.75% for high school students. The number of people suffering from myopia is increasing every year, and the degree of myopia is greatly increased, and there are not a few thousands of degrees of myopia. Preschool children don't use many eyes, but the proportion of myopia has also increased greatly.
Four. Conclusion:
(1) causes of myopia:
1. Preschool children suffer from myopia mainly because of congenital eyeball dysplasia. Amblyopia, strabismus, astigmatism and other eye diseases can easily lead to myopia.
2. Pupils' myopia is mainly due to watching TV too close, too long and too deep; Playing computer for too long; When reading and writing, do not pay attention to distance and posture, and read in the sun or carriage with too strong or too weak light; Not doing eye exercises seriously and other factors lead to eye fatigue, which leads to myopia or aggravation; Unreasonable diet; Look at the laser; Make up lessons, homework, piano lessons, dance lessons and other extracurricular training. Will make primary school students lack exercise and sleep too little.
3. In addition to the above reasons, middle school students' myopia is aggravated by heavy learning tasks, heavy pressure, more homework and less outdoor activities.
4. Genetic factors, environmental pollution and unbalanced nutrition intake are also important causes of myopia.
5. Failure to treat or wear glasses in time after suffering from myopia will aggravate the degree of myopia.
6. Inappropriate glasses, such as overcorrection or insufficient glasses.
7. Children in poor health, such as frailty, premature infants, malnutrition and partial eclipse.
8. If children eat sugary foods for a long time, their eyesight will also decline, because the intake of polysaccharides will cause insufficient absorption of trace elements such as calcium and chromium and vitamin b 1, which will reduce the elasticity of the eye ball wall and lengthen the eye axis, thus promoting myopia and deepening the degree of myopia.
(2) the harm of myopia:
1, easy to get hurt: nearsighted children wear glasses, because children are lively and active. If they are accidentally knocked out, their eyes will be punctured, which will seriously lead to blindness.
2. Decline in academic performance: Children with myopia can't see clearly without glasses. Wearing glasses can easily lead to visual fatigue and inattention, which leads to a decline in academic performance.
3. Affect children's future: children are nearsighted, and their major and employment choices for further studies are greatly restricted, and their future is greatly affected.
4. Hereditary offspring: Modern medicine has proved that myopia caused by acquired factors will be passed on to future generations if it is not treated in time.
5. Harm to physical and mental health: Because the child is nearsighted, he can't participate in various sports activities, which affects the normal development of the child's body, causing the child to be weak and sick, and his physical and mental health is greatly affected.
6. Low quality of life: Due to children's myopia, daily life is extremely inconvenient. For example, there are many difficulties in communication, travel and participation in recreational activities, resulting in psychological barriers and low quality of life.
7, leading to complications: if you get myopia, if you don't treat it in time, it will not only deepen the degree, but will eventually become high myopia, and it will also lead to complications such as retinal detachment, macular hemorrhage, glaucoma, cataract, and even blindness.
8. Too much inconvenience: The weather changes bring too much inconvenience, such as: rainy days, dark days, too hot in summer, too cold in winter, wearing glasses to go in and out, too large temperature difference is easy to frost, which will bring lens wear after wiping, leading to blurred vision and increasing degrees year by year.
Fifth, suggestions: effectively prevent eye diseases such as myopia:
1, to develop good living habits, reasonable diet, not partial eclipse, eat more foods containing vitamin C and vitamins A and D.
2. Correct bad habits, develop good eye hygiene habits, read and write correctly, have sufficient light, and insist on doing eye exercises.
3. Try to surf the Internet or watch other radioactive things as little as possible, and keep your eyes from getting tired for a long time.
4, to regularly check to the eye hospital, timely detection of eye diseases, timely treatment, follow the doctor's guidance, and gradually correct vision or prevent myopia from deepening.
5. If you already have eye diseases, you should stick to eye care. The practical results show that myopic amblyopia and other eye diseases can be restored to normal through effective health care before the eye development of 18 years old is finalized.
Investigation report on myopia II
First of all, the questions raised
The eyes are the windows of the soul and the important organs of people. Without them, we will lose this beautiful world. Many students in this class wear thick "beer hats" because of myopia. Among them, many students are very nearsighted. Why are they so nearsighted? This mystery has been haunting my mind. So, I launched an investigation and interview to find out.
Second, the survey method
1, investigation visit
2. Read relevant books, newspapers and periodicals.
3. Search the Internet for information about myopia.
Three. Investigation and data collation
1. What is myopia on the Internet? Myopia is a kind of I-vision defect. You can see things far away, but you can't see things near.
2. Investigate the number of nearsighted people. There are 5 1 person in our class, and the number of nearsighted people is 1 1 person, accounting for about a quarter of our class. Interview them why they are nearsighted.
Watching TV too much. There are three people.
B, reading while lying down. The number of people is three.
C, the writing posture is incorrect. There are three people.
Don't like doing eye exercises. The number of people is 1.
Play computer games. Number 2
Fourth, summary.
1, if you don't pay attention to your eyes and use them for a long time, it is easy to cause myopia. Such as: watching TV too much, reading while lying down, writing incorrectly, not liking doing eye exercises, playing computer games, and so on.
2. Myopia can be avoided, but "two musts" and "two don 'ts" are: 1. Read and write in the right posture, and keep the distance between eyes and books on a ruler. 2。 Take a rest after watching it for an hour or so, or look far away for a while. "Liangbie" is 1. Don't read or write in dim light and direct sunlight. 2。 Don't lie in bed, walk or read in the bumpy carriage.

Research achievements of verbs (abbreviation of verb)
(1) Myopia has become a common phenomenon.
At present, the proportion of myopia in most classes is increasing, exceeding the proportion of non-myopia.
(2) the cause of myopia.
The causes of myopia are: long-term incorrect reading and writing posture. Watching TV or computer or game machine for a long time.
Yes Long-term reading, long-term writing. In addition, it is also because most people do not pay attention to eye care. Did not insist on doing eye exercises, using eye hygiene and so on.
(3) Methods to correct myopia.
Myopia is often incurable, but it can reduce the degree of myopia. The specific method is as follows:
1. It is not advisable to use your eyes at close range for too long. You should rest every 45 ~ 60 minutes 10 ~ 15 minutes. When resting, you should overlook the window or do outdoor activities to fully relax the eye accommodation muscles.
2. The light should be moderate when you use your eyes at close range. Too strong or too weak light when using eyes at close range is an important factor causing myopia. Therefore, at night or in a dark environment, it is best to use 40~ 60w incandescent lamps for lighting and put them in the upper left corner of the desk. This is because incandescent lamps have soft light, good color rendering performance, and the eyeballs are easy to adapt to prevent eye fatigue caused by too strong or too dark light.
3. Close your eyes correctly. Close eye posture is another factor that affects the incidence of myopia. When using eyes at close range, the height ratio of tables and chairs should be appropriate, and books should be placed 30cm away from eyes. Bad eye habits, such as reading while driving, lying in bed or working at a desk, will increase the adjustment burden and convergence frequency of the eyes, and increase the pressure of extraocular muscles on the eyeball, especially for primary and secondary school students, whose eyeball is in a developing stage with a wide ball wall. Long-term bad eye posture can easily lead to abnormal eyeball development and myopia.
4. Take an active part in physical exercise to enhance physical fitness. Physical fitness is also closely related to the occurrence of myopia in adolescents. For example, children with malnutrition, acute and chronic infectious diseases, physical weakness, partial eclipse or gluttony for sweets tend to be nearsighted.
5, eye movement method: when the head rotates up and down, left and right, the eyes also move together.
6, blinking method: the head leans back and blinks constantly to make the blood smooth. When your eyes are slightly tired, you only need to blink 2~3 times.
7. Alternating hot and cold compress method: one towel is soaked in hot water slightly hotter than bath water, and the other towel is soaked in cold water with ice cubes. Put the hot towel on your eyes for about five minutes, and then put the cold towel for five minutes.
8, eye exercises: the middle finger is between the eye socket and the bridge of the nose, the palm covers the face, and it is rubbed back and forth for five minutes. Then slowly move your neck from left to right, then close your eyes and pat the back of your neck ten times with your fist.
(4) methods to prevent myopia.
1, use the correct posture, keep the distance between eyes and writing more than 25 cm, and form good habits. The desk for reading and writing should not be too high. Make the vertical distance between eyes and desktop not less than 27 cm (the distance between eyes and writing determines the degree of myopia, and the time of continuous reading determines the speed of myopia development), and it is best to control it at 27-33 cm.
2, reading and writing near the eyes for a long time (10 minutes or more), writing should have stable and suitable lighting (preferably with a desk lamp. Sunshine is good, but unstable) to ensure the stability of the distance between eyes and handwriting.
3. Keep enough sleep time and outdoor aerobic exercise, improve physical fitness and anti-fatigue ability, and maintain healthy retinal vision.
4. We should set up the idea of starting from one thing and a scientific way of thinking. Because preventing the occurrence and development of myopia can not be done once or twice a day for two days, but can be done for one hour at a time without prevention (0.0 1 degree).
5, myopia inheritance. Myopia is 40% hereditary. Then, we should pay more attention to prevention. If not prevented, you may be highly nearsighted. Sixth, gain experience.
This is our first comprehensive physical training. Although we are new here and have many difficulties, our team has a clear division of labor, and Qi Xin worked together to overcome all kinds of difficulties and complete the first comprehensive practical activity. Although there are many places that need to be improved, it is also a time-consuming and laborious work for us, and it is also a test of ourselves and our ability! Although this report is not perfect, it is summed up in the form of the results of our efforts over the past month, and the excitement in our hearts is difficult to express in words. All the sweat was not in vain. This time, the comprehensive physical practice activities have enabled us to exercise ourselves, enrich ourselves and improve our abilities. Let us remember that unity is strength and cooperation is sincerity!
The fourth report of myopia investigation
Number of nearsighted students in this class: 7.
Causes of myopia:
Reason (1): Reading is the most important. Most people who read a lot and study well have poor eyesight. Because some students don't read correctly, they don't achieve the three "ones", and their eyes are too close to the book, which leads to eye fatigue and unclear reading.
Reason (2): After lying down, the contact area between the body and the supporting surface (such as bed) increases, the pressure decreases, and the human body is in a comfortable state, so the nerve center will make people sleepy, thus promoting the rest of the brain and body (that is, sleep). At this time, people's brains are slow to respond and their memory is greatly reduced, which is very unfavorable for learning. Moreover, lying down to read books is easy to make eyes tired, and the elasticity of eye muscle fibers becomes smaller, which is easy to be nearsighted.
How to solve the problem of reason (1);
(1) Keep your eyes one foot away from the book;
(2) Don't read in the dark, the light is moderate, neither too strong nor too dark;
(3) Don't read for too long. After every 40 ~ 50 minutes, you need to rest 10 ~ 15 minutes to keep your eyes as far as possible to prevent your eyes from being overtired.
(4) Don't read books whose handwriting is too small or fuzzy;
(5) Don't lie prone on the table, tilt your head and read in bed.
How to solve rational problems (2);
Because it is difficult to keep a proper distance between the book and the eyes when lying down and reading the newspaper, it is often far away and near, which makes the lens of the eyes have to be constantly adjusted, which is easy to cause eye fatigue. At the same time, the blood vessels in the eyes are prone to congestion when lying down to read, and the light of the lamp is not ideal when lying down. After a long time, my eyes are tired and I am prone to myopia. Therefore, when reading books and newspapers, you should pay attention to your posture, not only have enough light, but also keep your eyes at an appropriate distance from the book, and don't read while lying down.
Therefore, I remind you that you must take good care of your eyes, which are the windows to your soul!
The fifth report of myopia investigation
First of all, the questions raised
There are many "four-eyed frogs" corridors in our class, and countless nearsightedness can be seen everywhere on the playground. According to China's statistics, the incidence of myopia among teenagers is the second in the world, second only to Japan. 22.7% of primary school students suffer from myopia, which has soared to 55.8% in junior high school and 70.3% in senior high school. Eight out of every ten people in the university are nearsighted, which is only the myopia rate of students. It is said that the total number of people with myopia in China accounts for 400 million. What makes our myopia rate increase like flying? How can we reduce myopia rate?
Second, the survey method
1, consult some related websites, websites and forums to find out the improvement of myopia and what methods can reduce our myopia rate.
2. Ask the nearsighted classmates around you and ask them how they think they are nearsighted.
Three. Arrangement and conclusion
They themselves think that their myopia is the reason.

Ding xuetong
Keep your head down when you do your homework and play computer every day.
I always keep my head down when reading, or my eyes are close to the book.
I watch TV so close that I watch it almost every day.
I often play computer games, and I can't look far after playing games for 78 hours.
Let's take a look at several factors found on the Internet.
1 genetic factor 2 nutritional factor 3 environmental factor
Let's look at the above factors, 1 genetic factors. Some parents of students may be nearsighted, but it is impossible for all parents of nearsighted students to be nearsighted, but genetic factors can't make us nearsighted in Baidu, at most about 60 degrees. Look at the nutritional factors. Now everyone has money at home, so it is impossible to have food, but they are nearsighted. For this reason, some students who are picky about food will have a rapid increase in myopia. Let's look at environmental factors. I think environmental factors are the biggest cause of our myopia. Look at the students above, most of them are caused by environmental reasons, some are radiation, and some are in the wrong posture. These are all caused by environmental reasons.
Is there any way to reduce our myopia rate?
Some people say that doing eye exercises can reduce the degree, and some people say that regular exercise can reduce the nutrition ... I found out in the book whether doing eye exercises can become a topic of decreased vision, and finally proved that eye exercises can not reduce our myopia rate, but can only alleviate our vision.
conclusion
We should use the optical principle to relax the adjustment. Do more eye exercises to prevent your eyesight from rising again. Don't stop when you don't need to wear glasses, because wearing more glasses will improve your eyesight. In addition, when playing games and watching TV, you should control your time and look far away.

Investigation report on myopia (Part VI)
I. Questions raised
Many students in our class put on glasses one after another. How many people are nearsighted? Why are they nearsighted again? I did a survey.
Second, the survey method
1. Through interviews, people who are nearsighted are more likely to be nearsighted if they do O?
2. Investigate students' eye habits and myopia reasons through online interviews.
1 myopia rate of respondents in information channels
I asked 25 primary schools.
Newspaper students 22.7%
Inquire about primary school students online 85%
70% of primary schools inquire online and read newspapers and periodicals online.
1 Internet search: The factors leading to myopia are: genetic factors, environmental factors, individual factors, nutritional factors and sleep factors. The main causes of myopia in primary school students are doing homework too late, not getting enough sleep, watching TV and playing computer too much, and consuming a lot of German and protein.
2. At present, the myopia rate of primary and middle school students in China has reached 34.6%, the myopia rate of high school students has reached 70%, the number of patients has exceeded 60 million, and the number of people who are blind due to myopia has reached 300,000. The decline of vision directly affects our academic performance, further studies and employment, and also hinders our physiology and psychology to varying degrees. According to a joint survey by the Ministry of Health and the Ministry of Education, the incidence of myopia among students in China is close to 60%, ranking first in the world.
3. The number of primary school students with myopia is not large, and the degree does not exceed 500 degrees at most. Most of them don't need to wear glasses for the time being.
3. The reasons for myopia of primary school students are as follows:
1. Poor posture when doing homework and reading, failing to punch a hole one foot at a time, even reading in bed, reading in bed with a flashlight after turning off the lights, which is too harmful to glasses! Nine of the 20 students in this class have poor eyesight because of reading.
I spend more time surfing the Internet and watching TV every day, without rest.
3. Not serious enough when doing eye exercises. When the person in charge leaves, I have to open my eyes from time to time, and the position is wrong.
1. Never read while lying down, let alone reading under the covers with a flashlight in the dark. Look at the writing homework and keep the posture of "one punch, one foot and one inch".
2, watch TV, use the computer, try not to turn off the lights, don't spend too long, be sure to stand up in the middle and rest in the distance, and play less if you can. Watching TV and playing computer for an hour requires doing eye exercises.
3, do eye exercises must be serious, you can't blink in the middle, the action should be in place, and you can call your own password when you are free.
The seventh report of myopia investigation
First of all, the questions raised
When glasses were mentioned before, everyone thought they were the patents of teachers, scientists and college students. In recent years, we have found that many students also wear glasses. Some students with poor eyesight can't see the words on the blackboard clearly because they don't wear glasses in time, which affects their study. On the day of the survey, the myopia rate of senior primary school students reached 20%, junior high school students reached 60% and senior high school students reached 90%. These situations have attracted enough attention from teachers and students. What are the causes of myopia in primary school students? How to prevent it? I decided to do some research on this subject.
Second, the purpose of the study
In recent years, the number of pupils wearing glasses has increased year by year, and how to prevent and correct myopia has become a common concern. Through the research of this topic, we can understand the myopia rate of primary school students, the causes of myopia, and the corrective and preventive measures of myopia, so as to enhance the awareness of protecting eyes and prevent and reduce the occurrence of myopia.
Third, the research plan
1, research content
(1) The cause of myopia.
(2) How to prevent myopia
2. Investigation methods
(1) Consult relevant books to understand how ordinary people are nearsighted;
(2) Understand the current situation of adolescent myopia through various channels.
(3) Searching relevant information on the Internet
Fourth, the research process
(A) to observe and investigate myopia students, to understand the usual use of glasses.
Through observation and investigation of classmates and friends around us, we know that most nearsighted students don't pay attention to eye hygiene.
(2) Consult an ophthalmologist and consult the information to understand the causes and preventive measures of myopia.
Go to the library to consult relevant information, go to the hospital to consult an ophthalmologist and make detailed records.
(three) summarize and analyze the investigation materials and write the investigation report.
After the investigation and research visit, I will sort out, analyze and write the research report.
Verb (abbreviation of verb) conclusion
Through investigation and analysis, I found that:
1. On the whole, most students have a heavy homework burden, and the higher the grade, the heavier the burden;
2. Most students don't give their eyes a good rest when doing their homework;
Although there are many more people who are nearsighted than those who are not, people who don't wear glasses still account for a considerable proportion. This shows that students pay insufficient attention to myopia.
Advising intransitive verbs
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.
Don't sleep in bed or read while walking. Don't read and write at your desk.
4. Don't use your eyesight for a long time. Take a break every 30 minutes of study 10 minutes.
5. Don't watch TV too often for too long, and control it within 1 hour. Not too close. At least two meters apart.
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.
Seven, experience
The eye is an important organ of the human body, the window of the soul, and the first element of people's life, study and work. 90% of people's access to external information depends on vision. Each of us needs to observe and perceive the beautiful world through our eyes. If myopia cannot be prevented and corrected from childhood, it will affect our long-term work and life in the future. Let's care about the eyesight health of primary school students and let every child have a pair of bright eyes.
