Myopia research report I
First of all, the topic is put forward:
Many students in our class have brought glasses one after another, and I am one of them. How many people are nearsighted? Why are they nearsighted again? I did 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%.
There are many reasons for myopia. According to our guess, there 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.
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.
Four. conclusion
Through the analysis of the questionnaire, I found that:
1. Generally speaking, the homework burden of most students is very heavy, and it increases with the growth of grades.
2. 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.
3. Anti-fatigue eye drops and eye exercises have therapeutic effects on eyes, but they have not attracted the attention of students.
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!
5. The 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.
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. Every 50 minutes of study, rest 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.
Myopia research report II
First of all, the topic is put forward:
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. Therefore, students, parents and society pay more and more attention to the prevention and treatment of myopia in children and adolescents. Why are there more and more nearsighted students? What about students' 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 questionnaire
1. Are you nearsighted?
A.yes, b no.
2. Why are you nearsighted? (Don't answer unless you are nearsighted)
A, watching too much TV B, sitting improperly C, others
How nearsighted are you?
A./kloc-below 0/00, below b. 500, above c.
Third, investigation and analysis: causes of 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 too close.
Watching TV for too long
The picture density of TV is too deep.
4 posture is not correct when doing homework.
Read a book in too strong sunlight
6 reading in weak light.
Sitting in front of the computer for a long time
8 unreasonable diet
9 observation laser
10 reading in the carriage
1 1 genetic factors
12 not doing eye exercises seriously
Fourth, 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.
Verb (abbreviation of verb) suggestion
(1) When reading, the posture should be correct and the light should be sufficient. When reading and writing, sit one foot away from the desk, keep your chest away from the desk and your eyes away from the textbook.
(2) Don't read while riding or walking, and don't read while lying down. Read and write 1 hour, overlook 10 minutes, or go outdoors to adjust your eyes and muscles.
(3) Insist on doing eye exercises for ten minutes between classes.
(4) 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.
(5) Don't be partial to food, eat less spicy food, and eat more foods containing vitamin C and vitamins A and D. ..
(six) to the ophthalmology department for regular examination, listen to the doctor's guidance, and gradually correct vision or prevent myopia from deepening.
Sixth, 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 research report 3
First, the topic is put forward.
Many students in our class have brought glasses one after another (some of them are to be cool), and I am one of them. Why are all the students in our class wearing glasses? So an investigation was launched.
Second, the solution.
1, ask students to understand the main reasons for their myopia.
2. Understand how people are nearsighted.
Third, organize information.
1, the eye distance is too close. According to relevant data, juvenile myopia is mostly caused by long-term close eye distance. Teenagers' eyes have strong adjustment ability. When the distance between the book and the eyes reaches 7- 10 cm, you can still see clearly. However, if they often read books at this distance, writing will make the adjustment of their eyes extremely tense, thus forming refractive (accommodative) myopia, which is called pseudomyopia. If the ciliary muscle is over-regulated for a long time and cannot flex flexibly, the convergence effect is strengthened due to over-regulation, so that the extraocular muscle exerts pressure on the eyeball, the intraocular pressure is increased, and the intraocular tissue is congested. In addition, due to the delicate eyeball tissue, the eyeball wall is gradually elongated, and the anterior and posterior axes of the eyeball are elongated. If it exceeds the normal value, axial myopia, the so-called true myopia, is formed.
2, the eye time is too long. Some teenagers read, write and do their homework, watch TV for 3-4 hours without rest, or even sleep until late at night, which not only affects their health, but also makes their eyes overburdened, and the muscles inside and outside their eyes are in a state of tension for a long time without rest. Over time, when they see far away, their muscles can't relax and become spastic, which makes them feel blurred and form myopia. It is for this reason that some students' eyesight drops obviously after a summer vacation.
3. The light is too strong or too weak. If the light is too strong, such as sunlight on the handwriting, it will cause strong reflection, stimulate the eyes, make the eyes uncomfortable, and it is difficult to read the font. On the other hand, if the light is too weak and the writing illumination is insufficient, the eyes can't see the font clearly, and the head will move forward and get close to the book. In both cases, the eyes are prone to fatigue, excessive adjustment or spasm of the eyes, leading to myopia.
Fourth, suggestions.
① Cultivate children's correct reading and writing posture, and the distance between eyes and books should be about 30 cm.
(2) When reading and writing, the light should be moderate, not too strong or too dark, and the light should be irradiated from the left front to avoid the shadow of the hand blocking the line of sight.
(3) Reading time should not be too long. Every 40 ~ 50 minutes, you should rest for 10 ~ 15 minutes, close your eyes or look far away for a few minutes or do eye exercises to prevent eye fatigue.
Don't read too small or illegible books and newspapers, and don't write too small.
⑤ Educate children to correct unreasonable eye habits, such as lying on the table, reading or writing with their heads tilted, reading in bed, reading at meals, reading in bright or dim street lights and moonlight, reading in a moving car, walking, etc. These bad habits will make the eyes excessively tired and reduce the acuity of vision.
Research report on myopia 4
Ask a Question
In our class, many people are nearsighted, and I am one of them. Why are you nearsighted? What causes myopia? What is the main reason? How to prevent it? To this end, I investigated the myopia of my half-classmates and analyzed the reasons.
investigation method
Ask the elders around you how to effectively protect your eyesight.
Investigate the classmates around you, all of them are nearsighted, and make a rough estimate.
The specific contents of all aspects involved in information channels
An effective way for elders to protect their eyesight orally.
1, sitting correctly.
2. Don't read in bed.
Don't play computer or watch TV.
The students' answers estimated the number of nearsighted students in the class. The number of myopia in our class accounts for about 40% of the total number of students in the class.
The main causes of myopia are heredity, too long reading time on the computer, too much pressure, calcium deficiency and too much intake of refined sugar.
Entering the senior grade and information age, thick glasses have become a trend.
We can't hesitate any longer. We must appeal to the whole world to be more like eyes.
You know, the eyes are clear pearls, and the eyes are the windows to the soul.
Myopia research report 5
Ask a Question
Recently, there are several pairs of glasses in our class, and several students have joined the glasses family. Why are so many students nearsighted? I decided to investigate my classmate's myopia.
investigation method
1. Interview to investigate myopia, class size and myopia reasons.
Browse online how to prevent myopia and pay attention to eye hygiene.
3. Consult experienced professionals.
There are 40 interviewees.
Myopia is mild, moderate, high, and not myopic.
The number of myopia is 2 1, 8, 2, 9.
The proportions are 52.5%, 5% and 22.5% respectively.
The main cause of myopia is not paying attention to the posture of reading. I often watch TV and play computer games. I play computer games and watch TV for a long time. Pay great attention to eye hygiene.
Most students in the class are nearsighted, so we need to find out the reason. Keep a good distance between reading, watching TV and watching computer screen, otherwise it will lead to astigmatism or myopia.
Students with moderate myopia and high myopia often watch TV and play computer. Seeing TV and computers is very harmful to our eyesight. We should watch as little or even not as much as possible, and don't let the lenses get thicker and thicker.
1, to develop a correct reading and writing posture, the distance between eyes and books should be about 30 cm.
2. Don't read books and newspapers whose handwriting is too small or fuzzy, and don't write too small.
3. Educate children to correct unreasonable eye habits, such as reading or writing on the table, reading in bed, reading while eating, and reading in strong light or darkness.
