Secondary school students myopia investigation report can be described from three aspects, the first can describe the purpose of the investigation report, the second is to describe the specific process of the investigation and data, the third to describe the results of the investigation report and analysis.
Secondary school students myopia investigation report:
Background: If you pay attention to the people around you, you will find that many people need to "eye assistant". Especially young people are in a period of high eye use, if you do not pay attention to the protection of the eyes will let it suffer serious damage. Therefore, the problem of myopia has become more and more serious.
Currently, China's myopic patients have more than 300 million, accounting for 1/3 of the world's myopic patients, and the myopia rate of our students in the world's rankings, has risen from the fourth after 1998 to the second, second only to the "myopia of the first big country" - Japan. -Japan. Middle school myopia rate has reached 34.6% of high school students myopia rate has reached 70%, China's youth due to high myopia and the number of blind people has reached 300,000 people.
According to the survey, the proportion of myopia occurred in the 70's about 15%, the development of the end of the 90's 55% or even 80% or so, the incidence of myopia in our country is rising rapidly, the whole society must pay attention to and take measures at the time
Group members: Luo Xing. Zuo Ping. Guo Yangyang. Zhang Teng, Su Hongyu, Fang Jingchao, Qin Zhen. Sheng Longying
Activity time:December 15-January 3
Activity scope:Street, school, eyeglasses store,
Investigation methods:Network information search, questionnaire, eye store survey
Proposed problem:According to the data of the online survey, the incidence of nearsightedness in China's adolescents has reached more than 30%, that is to say, 3 of 10 children are nearsighted, and the incidence of nearsightedness is more than 30%. have more than 3 are myopic. Elementary school students wear glasses for parents and teachers, has become accustomed to, kindergarten class children wearing a pair of glasses is not uncommon. This reaches about 50 percent in the high school age group. So why is the percentage of middle school students who are nearsighted so high? We have questions about this? Is it too much pressure to study? Or is it a habit? Or other factors. We investigated: (insert survey)
By visiting the major eye store, we learned that the phenomenon of myopia is showing the following characteristics: First, the incidence of myopia all the way up; secondly, the development of the lower age; thirdly, the cause of myopia is more and more diverse causes, and whenever the holiday period, the more eye store is "red-hot". Why? From the results of the survey, it is easy to see that watching TV, playing computer games has become one of the most important "killer".
The following is the discussion and research we have come up with the onset of myopia in adolescents involves five causative factors:
1, poor learning environment;
2, poor eye habits;
3, the genetic history of myopia in adolescents;
4, outdoor activities and physical exercise is less;
5, the average daily study time is long.
6, watching TV, playing computers or playing video games for too long;
Which poor learning environment, playing games and bad eye habits have a significant correlation for the onset of myopia in adolescents. With the development of society, which Article 6 had to be more and more shadow up our attention, watching TV and playing computer on myopia should have an impact, the key time is too long.
Problem solving:
With the discovery of the problem and step by step in-depth, our group members through the discussion of the summary analysis, summarized the following points to solve the problem:
1. At present, there are many schools there is the classroom design structure is unreasonable, lighting lighting is not in line with the provisions of the classroom, the classroom contains the number of students seriously exceeded the standard, the desks and chairs high and low, the spacing of the student height and so on is not suitable for the situation.
2. At home, parents should also create a good learning environment for students, so that their lighting, desk and chair heights are in line with health and hygiene standards.
3. Strengthen the work of school health education, vigorously publicize students' knowledge of eye hygiene, change the bad health behavior, develop good eye hygiene habits, improve self-care ability, and protect good eyesight.
4. Teachers and parents should persuade students to watch less television, especially to explain the hazards of watching television close to the eyesight; do not read in too dark, too strong light; ride in the car, walking, lying down, etc. Do not read. Also help students to correct incorrect reading and writing posture, as well as poor eye hygiene habits. For students with a genetic history should be more serious about protecting their eyesight, and the factors and habits that jeopardize their eyesight should be resolutely corrected.
5. We insist on promoting and popularizing eye exercises so that students can learn and do them correctly, consciously and conscientiously, and check their eyesight regularly, so that they can be detected and corrected as early as possible.
6. When myopic students need eyeglasses, they should go to the medical department for consultation, optometry and prescription, and should not wear myopic lenses in the street optician's store at random.
7. In diet, students should be given more food rich in vitamins A, D, B2. To educate students to reasonably arrange the study time, the study time should not be too long, in the study interval to consciously let the eyes rest rest, so as to play a combination of work and rest, to protect the eyesight, improve the learning efficiency of the role.
8. Watching TV and playing computer should not be more than 40~50 minutes each time, in the middle of the rest should be, both eyes to the distance, in order to reduce eye fatigue, can avoid myopia deepening.

No 8 people --
Not sure 15 people --
Will - 52 people
Won't - -22 people
Analysis:
From the questionnaire. Secondary school and the main factors in the formation of myopia are as follows:
First, do not pay attention to eye hygiene. Eyes are very picky, a little inattention will be infected with a variety of eye diseases. Among them, myopia is the most common now. In order to protect your eyes, you must pay attention to eye hygiene, such as: do not rub the eyes, do not fall into the eyes of foreign objects, do not apply irritating substances around the eyes? But nowadays, some middle school students neglect eye hygiene for various reasons. For some reasons, they neglect eye hygiene and make their eyes nearsighted.
Secondly, overtime watching TV, surfing the Internet and reading literature. There are a lot of students who are nearsighted because of the indirect reason that they study too much, but some of them are nearsighted not because of the urgency of time, but because of the time they have to kill time because they have a lot of time to spare. So they start watching TV, surfing the Internet and reading novels, and over time they become mesmerized. As we all know, the radiation from TV and computer will stimulate the retina of the eyes, and reading books for too long will cause fatigue. After a long time, naturally, myopia.
2. Here is the information we downloaded from the Internet:
China Education News, March 21, 2005, page 8, almost 8 out of every 10 Chengdu middle school students in Chengdu are nearsighted (including those who do not wear glasses, "pseudo myopia" and those who are called "low vision people" by ophthalmology science). "
The city's high myopia rate has been rising since the 1970s, with a significant proportion of them developing a high degree of myopia. The average visual acuity of the left and right eyes of those who need glasses is equal to or less than 0.6. Zhang, who is studying in the first year of high school, said that he was just in the first year of junior high school, his myopia is less than 100 degrees, but with the aggravation of the learning task, the time for extracurricular play is less and less, and the time for reading is increasing every day, and the time spent on the eyes is long, and the seeing is getting more and more blurred, and he is now wearing glasses with a thickness of nearly 500 degrees, which makes him feel very inconvenient. Zhang, who lives in Changmao neighborhood, told us that he has become a "national treasure" in the class without myopia, and everyone envies him for having a pair of eyes with normal vision
3.Survey of eyeglasses shops
We went into the streets and investigated in depth in the major eyeglasses stores. In response to the issues we discussed, we asked them to understand the reality of the current situation in society. Through careful interviews, we learned that the number of high school students come to the eye accounted for about 3/5 of the total number of prescription glasses. This is a good illustration of the need to pay great attention to this problem, to avoid letting it deteriorate again and again. Maybe things are not as alarming as I said, but small worries can become big worries, just as "an ant hole, though small, can break a thousand miles of dike". That's why we have to take precautions first.
With a curious mind, they don't pay much attention to behaviors that can lead to myopia (even if they do know about it), and generally think it's no big deal. Because of this, myopia took advantage of the situation and started attacking people's eyes rampantly, while causing them to become eyeglass enthusiasts.
On the prevention and treatment of myopia:
1. Eat more fresh vegetables, fruits, soybean products, seaweed, etc., eat less candy, and do not be partial to food.2. Various forms of distant vision, such as can be identified at night in the sky full of stars, look into the distance trees or buildings, etc..3. Do not use too light, too short, too sharp pencil.4. Can be used to incandescent and fluorescent lamps mixed light illumination, the light preferred left or left front.5. Pay attention to eye hygiene, do not read in bed, in a moving car, while walking, in sunlight or in dark light. When watching TV, people away from the TV 2.5-3 meters; TV is slightly below the horizon; continuous watching 1 hour should close the eyes to rest for a few minutes; if continuous watching 4 hours without resting, the visual acuity will fall 0.2. In short, in a word, to overcome the prolonged use of the eyes and the problem of near eye use, in order to prevent the occurrence of myopia.
Picky eating and partiality will make the children's eye development required by the supply of nutrients is insufficient. Therefore, to prevent myopia, children's recipes should be diversified, pay attention to meat and vegetables and coarse and fine combinations, in order to ensure that their eyes are adequately supplied with nutrients. You can eat more food that strengthens the spleen, nourishes the stomach and replenishes qi and blood, such as longan meat, yam, spinach, millet, corn and so on. At the same time, mulberry, black beans, red dates, walnuts and other foods can play a role in nourishing the heart to calm the mind and brighten the eyes. Then, protein, calcium, phosphorus and vitamins should also be supplemented. Supplementary zinc and chromium and other elements are also very important, soybeans, almonds, seaweed, kelp, lamb, yellow fish, milk powder and other foods containing high levels of zinc; beef, grains, meat, liver and other foods rich in chromium.
Nearsightedness prevention and treatment 6 points
①Prevent eye fatigue: such as long hours of reading, homework, watching the computer, lying down or reading in dark light. ② reasonable glasses: more than 50 degrees of myopia should be equipped with glasses, 250 degrees or less only in the distance wear, 250 degrees or more should be worn frequently, the best to see close with defocus lenses.
③ wear defocus lenses: primary and secondary school students myopia should be used as early as possible defocus myopia control lenses, the use of defocus lenses will be reading, homework or play computer myopia caused by the development of myopia control to a minimum.
④Preventing amblyopia and astigmatism: amblyopia should be cured as early as possible, and astigmatism above 100 degrees should be corrected by wearing lenses frequently. ⑤Anti-myopia surgery: children under 10 years old with myopia of 450 degrees or more should have posterior scleral reinforcement surgery as early as possible if they are developing fast.
6 laser surgery: after 18 years of age, when myopia is stable and not developing, excimer laser can be used to eliminate myopia and remove glasses.
Additionally, children and teenagers should play less video games, watch less TV, do more outdoor activities, strengthen exercise, go to bed early and get up early, correct partiality, reasonable lighting, check vision in time, early detection and early treatment, which are also of great significance to the prevention of myopia.
Prevention of myopia "three words"
Myopia, see not far, do things, inconvenient, to prevent, not difficult;
Do it, to be serious. The light is dark, don't look, hurt your eyes, damage your eyesight.
Warm homework, an hour, stop and look again. When you read, sit upright;
Eyes a foot away from the book. Don't read in the sunlight; too much light will make your eyes glaze over.
The following is our activity:
Now the myopia rate of our secondary school students has been increasing year by year, and it has become a time when society must pay attention and take measures. During the interviews, we learned that the problem of myopia is not taken seriously by secondary school students, so that the knowledge of myopia is not well understood. For the problem of myopia, most of the secondary school students have curiosity, a few secondary school students even desire to be myopic, this is the general psychology of secondary school students on myopia, there are such cases around us, some students just feel fun at the beginning, take the glasses to pretend to be cool. In the end, they really can't live without glasses, and then they start to regret it, which is really a mistake! This is probably one of the main reasons for myopia!
Second report on myopia in secondary school students:
I. Raising the issue
In today's society, where there are so many talented people, it is extremely important to have a healthy body. The development of large cities, high-rise buildings, streets and alleys across everywhere, people close to nature less and less opportunity, people are busy, seldom stop for a while, relaxation. The myopia of secondary school students is becoming more and more serious. In the class, students are wearing glasses, for the vision of secondary school students, I did a survey on the vision of secondary school students in Xingtai City, Hebei Province, Yucai Middle School, junior high school sophomore class 6 students about the vision of secondary school students.
Second, the purpose of the survey
The survey on the vision situation of secondary school students makes realize the seriousness of secondary school students suffering from myopia. Put forward the initiative to convey the danger of myopia to the students, so that the students realize that they have to protect their eyes.
Third, the investigation process
1. Literature research method
(1) What is myopia?
We all know that the basic structure of the eye is composed of several major parts such as cornea, pupil, lens, retina and iris. The tube passes through the lens and is imaged on the retina, and then the optic nerve transmits the information to the brain and produces vision, so the person sees the object clearly, which is the working principle of the eye.
Nearsightedness is a type of vision defect in which you can see things close up but not far away. Myopia is caused by the distance between the lens of the eye and the retina is too long or the refractive power of the lens is too strong, so that the image that enters into enter into the eye can not fall squarely on the retina but fall in front of the retina.
Concave lenses are required for myopia: Because concave lenses have a dispersing effect on light, it is the light that was originally focused in front of the retina that is dispersed and then focused right on the retina.
(2) junior high school students vision loss causes
First of all, the environment is the main factor of myopia, eye fatigue and not use the eyes, so that a lot of young people's eyes gradually decline in the regulation of the function of the eyes and destroyed. Now the problem is that the student desks and chairs are not standardized, failing to configure according to grade level, individual differences, not easy for students to develop a sitting posture. Poor lighting in the classroom is also easy for students myopia. In addition, long contact with fluorescent objects, such as television, computers, etc., the cause of student vision loss. So it is said that the poor learning environment is a serious health of the students.
Secondly, do not participate in physical exercise, poor physical fitness can not, from the information searched on the Internet: the body of students myopia rate is smaller than the ordinary colleges and universities, only four points. With the sports professional students less burden of coursework, another, also with the sports professional students love sports, physical fitness. Ordinary school girls than boys do not love sports, also girls myopia rate is higher than that of boys.
Once again, unscientific eating habits can also myopia. The clinical data and animal testing illustrate: myopia and the body calcium, chromium and other trace elements. Sweets for acidic food, a consumption of calcium in the body, another elevated blood sugar, crystal osmotic pressure, is another bane of myopia.
2. Do an interview with the "eye power optical store" around Yucai Middle School.
Q: Who are the majority of people who come to get myopia glasses?
A: The largest number of students are middle school students.
Q: What is the degree of myopia among students?
A: 100-200 degrees.
Q: Myopia without glasses vision will get deeper and deeper?
A: It depends on the protection. Some students with true myopia, as long as the protection, prevention, is the problem.
But myopia has been more than 200 degrees, such as not wearing glasses, the study, but also myopia degrees, is very bad. In short, regardless of myopia, protect the eyes to be.
Q: myopia causes?
A: secondary school students myopia causes:
1, reading and writing posture is not;
2, reading and writing without paying attention to the intensity of the light;
3, life and learning system is not sound;
4, congenital factors.
Q: The common sense of wearing glasses is?
A: glasses should be made before dilated optometry, diagnosed as myopia; with glasses, should be the right degree of glasses, the degree should not be too deep or too shallow; with glasses, still need to pay attention to eye hygiene to prevent. To check the vision, such as vision loss, we must re-lenses.
Q: can make some suggestions for secondary school students myopia?
A: eye hygiene; myopia to be equipped with glasses; more green, look away to regulate the eyes. Prevention of myopia, the last to "three to" and "four do not see".
3. Distribute questionnaires and briefly interview students
In order to further understand the vision of junior high school students, a questionnaire survey and a brief interview with 65 middle school students in the 6 classes of the second year of Xingtai Yucai Middle School. Detailed questionnaires are as follows:
Four, the results of the survey analysis
After my questionnaire survey, the results obtained are as follows:
According to the statistics, among the survey, there are 63.08% of the students are myopic stage, which is more than one-half of the total number of students.
2. Myopia years
The information in the figure of 23.1% and 17.2% respectively. What does this mean? One, junior high school to senior high school to the school and the students brought, serious middle school students unhealthy eye; the other, the students' awareness of healthy eye, consciously developed habits. The school and the students' awareness of healthy eye use is not strong.
In the meat 23. dietary habits of myopia is the direct cause, but also belong to the cause. For example, carotene, vitamin A, B2, will make the eyes easily fatigued, thus myopia. You should eat more vitamin A, B2, carotene-containing foods, such as milk, animal liver, eggs, peanuts, carrots, vegetables and so on. But also look at the book, here does not mean the category of the book, but refers to the posture when reading books to follow the "two to two do not" principle. The so-called: "two to" refers to the eyes and books to a distance of one city feet, and continuous reading for about an hour, to rest for a moment to look into the distance for a while, and "two do not" refers to do not read in the light of the light and sunlight and do not lie in bed to see. However, the data show that students usually read closer to the written word and lie in bed to read accounted for 46.3% of the students surveyed. Although diligence is good, but the results and damage to the eyes, it is a pity.
Only nearly 9 percent of the students, which is not bad.
The, and not to mention the academic performance of this, just television and computer radiation is very easy to myopia, and students in watching television and play computer games, more than 70% of students are watching television for two hours, long to the eyes of the excessive burden and do not rest, myopia is only a matter of time.
V. Summary
Through this activity, I learned that the situation of myopia in secondary school students, in general, is not optimistic, and the causes of myopia have a deeper understanding, know how to prevent myopia.
How to make young people correct eye health? You can investigate the proportion of secondary school students with myopia and the causes of myopia to let young people know the harmful effects of myopia, young people's awareness of self-healthy use of the eyes.
To this end, we sincerely give the following suggestions, hope that the protection of your eyesight, to prevent the expansion of the myopia team.
1. Strengthen the eye health education
From the survey, there is a part of secondary school students posture is not and the distance is close to the vision loss, indicating that the students of the daily posture, the appropriate distance to the significance of the protection of eyesight has not been a correct understanding of the importance of and attention. This requires
Our teachers in teaching and daily life to the students' behavioral habits to educate, emphasize, students' awareness of eye protection. We believe that eye health education should start in elementary school, a school should be "three to two do not" habit education, so that students will be required to habitualization from childhood.
2. To pay attention to the rest of the eyes
Surveys have shown that long study time is the main reason for vision loss. Now the college entrance exams, secondary school exams, junior high school exams are becoming increasingly competitive, with extended time, sea of questions to pursue the rate of advancement, will make the students' eyesight decline, resulting in never be able to make up for the loss, but also will make the students' physical fitness declined, a serious obstacle to learning, so the teaching of all disciplines have the responsibility to help students from the sea of questions to free, reduce the intensity of learning, so that students have time to pay attention to the rest.
3. To take a positive approach to maintaining and correcting
Eye exercises have been most students, so the school should increase the number of uniform exercises where appropriate, while teachers should be seriously counseling, correct errors, so that it plays a real protective role. Part of the myopia of secondary school students is now only pseudomyopia, if attention is paid to the protection, but also can be restored, some have become a true myopia, this time should wear appropriate glasses to correct to ensure that vision no longer decline, can not be casually coping with it, so myopia should be to the hospital to prepare glasses.
4. Reasonable diet
Dietary protein, reduce the supply of carbohydrates, can make a genetic background and the occurrence of myopia in adolescents to reduce or abort the increase in myopia. Therefore, in order to avoid myopia, eat less candy and high sugar foods. Too much sugar, will make the blood produce a lot of acid, acid and muscle salt, is the calcium phase, the blood calcium, which will be the toughness of the eyeball wall, so that the eye axis is easy to elongate, contributing to myopia and the development of myopia. Surface, prevention of myopia can be supplemented with protein, calcium, phosphorus, carrots, bean sprouts, oranges, mandarins, jujubes and other vegetables and fruits are also beneficial to the prevention of myopia.
5. Publicity
Schools can publicize the nature of vision protection on blackboards, lectures and other publicity to introduce ways to protect vision and strengthen the awareness of protection.
6. Watch less TV, play computers and game consoles, more contact with nature
From the survey, we know that the number of myopic people in Dali is much larger than the number of myopic people in Chaoyang, which in the end is for it? There are important factors around the environment, Chao Yang City, surrounded by mountains and the sea, the countryside in the green hills, many students can walk around after studying, look around the green hills, relaxation, which is also helpful to the eyes, to be more in contact with nature. And Dali life affluent, television, computers and game consoles in every household, students are addicted to television, computers or game consoles after school, on the eyesight is very serious.
To this point, the report finally came to an end, the heart of a big stone also put down. In the paragraph, really learned a lot of knowledge. More is learned to analyze the problem thinking method. In the process of collecting materials, learned the division of labor and cooperation, help each other, a deep friendship? All of them have made great gains.
In the whole process, there are many small episodes, the taste can not be one, but really Xing very happy, this is for the experience, experience, a wealth. Beginning of society, love of life. The exercise is needed, it can be the quality of life-long benefit.
The investigation activities, are aware of the poor eyesight to bring a lot of inconvenience, the eyes are the most sensory organs, everyone's experience and knowledge, the big is through the visual or get, it personal health, safety, interest in life? It hinders the learning activities, which shows the importance of vision care. Eyes are equal to wealth for everyone, to protect the eyes properly.
Eyes are the window of human eternity - you and my wealth.
The eyes are the eternal window of mankind - your wealth and mine.
1, you are not myopic?A Yes B No
The number of myopic eyes accounted for the percentage of the number of people surveyed is now, students of myopia has been a topic of concern. According to statistics, among this survey, there are 51 students are myopic stage, accounting for about two points. Among all the investigators, the number of myopic people in Dali is much larger than the number of myopic people in Chaoyang. Chao Yang's myopia number only accounted for three points.
2. When did you start to be nearsighted?A. Elementary school stage B. Middle school stage C. Before going to school
From the above table, it can be concluded that nearly 55% of the students started to be nearsighted in the middle school, and nearly 30% of them in the elementary school stage.
What does this mean? One, junior high school senior high school to the school and the students brought, serious middle school students unhealthy eye; another, students healthy eye awareness, consciously developed habits. The look of the school and students on the health of eye awareness is not strong.
3. What is the ratio of vegetables and meat you eat?
A. Vegetables = meat B. Vegetables 〉 meat C. Vegetables 〈meat
From the above table, it seems to eat vegetables less than meat 36%, vegetables equal to meat 41%, but vegetables greater than meat 23. dietary habits of myopia is the direct cause of myopia, but also belong to the cause. Carotenoids, vitamins A and B2, for example, make the eyes easily fatigued and thus myopic. To eat more vitamin A, B2, carotene-containing foods, such as milk, animal liver, eggs, peanuts, carrots, vegetables and so on.
4. What is your reading posture?
A closer to the written B away from the written C lying in bed D on the road to see E other
In addition, the interview, know that in the vacation there are 24 is in the reading of books, reading books is not a bad thing, but also look at the reading of the book here does not mean that the category of the book, but rather refers to the posture of the book when reading to be. To follow the "two to two do not" principle, the so-called: "two to" refers to the eyes and the distance between the book to a city feet, and continuous reading an hour or so, to rest for a moment to look into the distance for a while, and "two do not The "two don't" means don't read in low light and sunlight and don't lie on the bed to read. However, the data show that students usually read books closer to the written and lying in bed to read books accounted for 64.5 percent of the students in the school. force is good, but the results of the damage to the eyes, it is a pity.
5. You now have an average degree of myopia in both eyes
A.100 degrees B.100-300 C.300-500 D.500
From the above table, we can see that 100 to 300 degrees of false myopia is the students, 500 degrees of myopia is only nearly 9% of students, which is not bad.
6. You usually like to do?
A. Watching TV B. Reading books C. Playing computer games D. Physical activity E.
Survey analysis, in the students' weekday vacations, about 22 people are watching TV and playing computer games, and not to mention that this is on the academic performance of the light is the radiation of the television and computer is very easy to nearsightedness, and the students in the television and play computer games, more than 70 students were Watching TV for two hours, long to the eyes of the excessive burden and do not rest, myopia is only a matter of time.
What does this mean? One, junior high school senior high school to the school and the students brought, serious middle school students unhealthy eye; another, students healthy eye awareness, consciously developed habits. The school and the students' awareness of healthy eye use is not strong.
This activity, to the situation of secondary school students myopia, in general, not optimistic, and the causes of myopia deeper, know how to prevent myopia.
How to make young people correct eye health? Can investigate the proportion of secondary school students myopia number of causes to let teenagers know the harmful effects of myopia, teenagers self-awareness of healthy eye use.
To this end, the sincerity of the column recommendations, hope that the protection of vision, to prevent myopia team.
1, eye health education
From the survey, there is a middle school students posture is not and the distance is close to the vision loss, indicating that the students of the daily posture, the distance of the significance of the protection of eyesight is still understanding and. This requires the teacher in the teaching and daily life to be in the habit of students' education, emphasize, students to protect the eyes of consciousness. The eye health education should start from elementary school, a school should be "three to two do not" habit education, so that students will be required to habitualization from a young age.
2, pay attention to the rest of the eyes
Survey shows that the study of long is the main reason for vision loss. Now the college entrance exams, secondary school exams, junior high school exams are becoming increasingly competitive, with extended, sea of questions to pursue the rate of advancement, will make the students' eyesight decline, forever make up for the loss, but also make the students' physical fitness declined, seriously prevented the study, the teaching of all disciplines have the responsibility to help students from the sea of questions to free themselves, reduce the intensity of the study, so that the students have to pay attention to the rest.
3, to methods and corrections
Eye exercises have been the majority of students, the school should be in the case of the number of exercises, the teacher should be counseling, to correct the error, so that its real protective effect.
