Third, let's talk about myopia.
Section 1: Talking about nearsighted students
1, exchange and summarize the investigation 1 before class.
A questionnaire on the wearing of glasses by students in Class Four, Grade Five.
Number of people wearing glasses
Name of the person wearing glasses.
comment
Grade?One
Grade?Two
Grade?Three
Grade?Four
Grade?Five
2. By observing the survey data, it is concluded that with the growth of grade, more and more students wear glasses in the class.
3. Summary: Yes, this is the reality of myopia around us. I believe that after reading the following sketch, you will have greater feelings.
Plate 2: People who see myopia
1, sketch performance "A joke about myopia"
Summary: Because of myopia, students often write very loosely in Chinese learning. Math study is always caught? Decimal point? Teasing, in life, you either admit the wrong person, or you can't recognize the wrong person, making a fool of yourself and worrying about your myopia.
2. What do you think after reading this sketch?
Plate 3: Think about myopia.

Homework habit is low, and you don't like outdoor activities during recess?
(Take this as an example)
2. Each group summarizes the investigation and draws a conclusion.
3, the whole class exchange survey conclusions.
From our observation, we can find that most nearsighted students have the following behavior habits:
Watching TV is too close
Watching TV for too long
The TV pictures are too dense.
The posture of doing homework is not correct.
Read a book in too bright sunlight.
Reading in the dim light.
Spend a lot of time in front of the computer
Unreasonable diet
Reading in the carriage
hereditary factor
Don't do eye exercises seriously
Summary: Now, starting from the people and things around us, we have found the reason why the number of nearsighted students is increasing year by year. How can we prevent this situation from continuing?
Fourth, myopia, you, me and him.
Plate 1: I know the common sense of eye protection.
1, reading? Five, isn't it?
You can't read in the dark. You can't read in the sun.
You can't read on the road. You can't sit in the car and read.
You can't read on your back or stomach.
2. Pay attention to eye exercises
Cut your nails frequently, keep your hands clean, keep your rhythm accurate and keep your posture correct.
Step 3 pay attention to your diet
Chewing hard food: Is chewing considered as an alternative? Eye exercises? . Eat more chewy hard foods such as carrots, potatoes, soybeans and fruits to increase the chances of chewing and prevent myopia.
Eat more citrus and green vegetables: nutritionists suggest eating more citrus fruits and green vegetables every day to increase the intake of lutein and prevent vision degradation.
Zinc supplementation: Studies show that the zinc content in hair and serum of adolescent myopia patients is significantly lower than that of normal vision, and zinc supplementation can improve the vision of myopia patients.
Calcium supplement: not only for the skeletal system, but also for the eyes. Calcium deficiency will lead to the decrease of elasticity of the eye ball wall, and the eye muscles will be easily tired, which will deepen myopia.
4. Summary: Sing "Eye Protection Song" together.
Protecting your eyes is really important. Children should remember it.
Sit up straight when reading and writing, with your eyes one foot away from the table;
Don't read when you are lying by car;
Do eye exercises every day, twice a day.
Plate 2: Like eyes to promote my participation.
1、? Eyes? Introduction:
The incidence of myopia is getting higher and higher now. The myopia rate in Shanghai, Beijing and other large and medium-sized cities can reach 50%-60%. In medical colleges, the myopia rate is even as high as 70%-80%, and the myopia rate in the third and fourth grades of primary schools is also 30%-40%. A recent survey shows that the incidence of myopia in primary school students in China is 22.78%, that in middle school students is 55.22%, and that in college students is as high as 76.74%. Each of us has the responsibility and obligation to participate in similar publicity activities.

Fifth, the introduction of poetry needs it.
1, poetry recitation performance-"Window to Protect the Mind"
The eyes are the windows to the soul.
It is our inner window to understand the world.
Eyes, let us see the beautiful nature
Watching the flexible grass dance in the breeze.
Look at the happy frog jumping on the lotus leaf.
Everything is so beautiful.
Because we have a pair of bright eyes
To see all these beautiful scenery.
If one day, we lose our eyes.
Without this bright window
Our lives will be eclipsed.
A world shrouded in darkness
Besides fear, it is darkness.
Even if you work hard.
You can't see the colorful scenery outside the window.
Even a flower smiles in the sun.
Can't go through the window of the heart.
To your heart.
Do you really want to live in darkness forever?
I definitely don't want to
Then let's take good care of our eyes
Protect this precious window of the soul.
Make it brighter
Only in this way
We can see a more beautiful world.
A brighter tomorrow
2. Summary:
Students, in order to make our life beautiful forever, let's make love to our eyes from now on, protect our eyes and propagandists, * * * protect the windows of our hearts and welcome a better tomorrow! .
