The number of nearsightedness in our class has doubled or tripled since the second volume of grade four, and the people in our group also wear glasses. I feel very puzzled. So I launched an investigation into it.
Second, the survey method
1. Find out how many people in Class One are nearsighted through various channels and make records.
2. Investigate the number and growth trend of myopia through interviews.
3. Investigate students' eye habits and myopia reasons through online interviews.
Third,
The specific contents of all aspects involved in information channels
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 myopia blindness has reached 300,000. 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. ...
According to the survey, 3 people have myopia degrees below 50 degrees, 6 people have myopia degrees-150 degrees, 6 people 150 degrees -300 degrees, 3 people have myopia degrees above 300 degrees and 2 teachers have myopia degrees above 500 degrees.
According to the survey, 18 people are nearsighted, accounting for 9/23 of the class, among which 2 teachers are nearsighted, and ***20 people account for 1 of the 24 teachers in the class, and * * * accounts for 5/02 of the total class.
Investigation and Interview Students are used to reading with their eyes. They all like reading while lying down. They are close to each other when doing their homework and reading, but they don't play an inch. One-third of the students spend too much time using computers and watching TV without rest. ...
Four. conclusion
1. 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.
The number of nearsighted students in this class is not very large, and the degree is no more than 500 degrees at most. Most of them don't need to wear glasses for the time being.
The students in this class are nearsighted for the following reasons:
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.
Verb (abbreviation of verb) suggestion
Eyes are the windows of the soul, don't damage the windows of the soul. Therefore, developing good eye habits is the key to protecting eyesight.
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.
I hope it helps you!
I also hope that everyone can adopt my answer.
