Chao: I want to ask the students to guess a riddle: upper hair, lower hair, and a black grape in the middle. With it, you can read books and newspapers, and with it, you can see the world. (answer: eyes)
Sa: Yes, I believe all the students know that they are eyes. The reason why we can see our relatives and friends and see such colorful nature is precisely because each of us has a pair of bright eyes. When we communicate, it is a good helper for us to express our feelings, so it is also called the window of the soul. However, if we don't pay attention to our eyes, we can't see everything around us. We must wear glasses. In severe cases, we will be blind. How terrible! So today, let's have a theme class meeting and talk about the window of the soul-our eyes.
He: I announce the class meeting with the theme of protecting and caring for eyes, starting now!
Chao: I'd like to ask the students to say first: What role does the eye play in people's life? Reading, writing, playing computer, watching TV and walking? Can bring us light and let us observe many things? )
Sa: Eyes are so important to us, but if we don't take good care of them, they will get hurt and become nearsighted.
Chao: I'll tell you a story like this: (eyes crying)
Sam: What's the matter, class? What inspired you after listening to this story?
Chao: It seems that if you don't protect your eyes, you will soon be nearsighted. Ask students to talk about it. What other reasons can lead to myopia? Incorrect reading and writing posture, watching TV and playing computer for a long time, reading in too strong or too dark light, lying and riding a book, hiding in a quilt, rubbing your eyes with dirty hands and playing video games? )
Sam: The eyes are the windows to the soul. How happy it is to have bright eyes. But if we don't pay attention to protection, we will become nearsighted and have to wear glasses.
Chao: Next, let's invite the students out of the classroom? Little doctor? He has a question to test everyone.
H: Students, do you know the date of National Eye-Love Day? (June 6)
Yes, June 6th this year is the 17th National Congress? Eye love day? . What is the theme of Eye Love Day in 2008? Bright eyes for the Olympics? .
This year's national? Eye love day? There are six campaign slogans. First of all, it is everyone's responsibility to prevent juvenile myopia. The second is to care for your eyes, and the world is waiting for you to discover; The third is to prevent myopia, starting today; The fourth is to prevent myopia among teenagers, starting from bit by bit; The fifth is to welcome the Olympic and Paralympic Games. I saw it. I was involved. Sixth, everyone has the right to watch.
Sam: You don't know the importance of something until you lose it. Next, let's play a game and feel the importance of eyes. Children who don't draw eyes on the blackboard, please cover your eyes and draw them.
Tide: Unconsciously, today's activities will be over. Finally, please ask the class teacher to speak.
Speech 2 by the host of the National Eye-Love Day Class Meeting: Good afternoon, dear teachers and students. Like eye protection, starting today? The theme class meeting begins now.
Zhang: Today is
June 6th, 20 14 is a special day-World Eye Care Day. Eyes are the most important organs in human senses, and there are about
80% of knowledge and memory are acquired through the eyes.
Xia: You need your eyes to read, read and appreciate the pictures, people and beautiful scenery. The eyes can distinguish different colors and different lights. Eyes are the source of most of our information.
Zhang: The eye is not only an important visual organ, but also the center of appearance, the focus and main symbol of beauty.
Xia: But if we don't take care of and protect our eyes, we will suffer from myopia.
Zhang: People who are nearsighted can not only see distant objects clearly, but also easily suffer from visual fatigue. Because you often squint at things, it will make the extraocular muscles and ciliary muscles excessively tense, which is easy to cause eye fatigue. Sometimes they like to put books close to each other in order to see the fonts clearly, which will aggravate the adjustment of their eyes and promote the development of myopia. If they read, write and watch TV for a long time, they will feel dry eyes, heavy eyelids and sore eyes.
Xia: Because I can't see the blackboard clearly, I can't concentrate, and my academic performance drops. Wearing glasses is not conducive to children's participation in sports activities, and not all myopia can reach normal vision after wearing glasses. Myopia often has floaters, which will distract attention. High myopia is prone to vitreous degeneration or vitreous liquefaction. Because the eyeball becomes longer, the sclera becomes thinner, the eyeball protrudes, and the retina and choroid atrophy. It is prone to complications such as cataract, disuse exotropia, retinal hole, retinal hemorrhage, retinal detachment of different sizes, macular hemorrhage or macular degeneration. Besides retinal detachment, the biggest danger is macular degeneration, which initially leads to visual impairment or visual distortion, and finally leads to complete loss of central vision. Patients with high myopia,
Zhang: After listening to our introduction, I think everyone doesn't want to suffer from myopia, so how can we prevent myopia?
(1) Pay attention to choosing listening rather than reading in learning to reduce the load on your eyes.
(2) Avoid continuous close-ups for too long. Pay attention to reading, writing and computer operation. After reading continuously for nearly 40 minutes, take a rest and look at the distance 10- 15 minutes. Try to control the cumulative close-up time every day, preferably no more than 6 hours.
Xia: (3) Pay attention to improving the environment that takes a long time to see. The classroom light should be bright, the desktop and blackboard should not be too reflective, and there should be windows on both sides, neither too high nor too small, so that you can see the window at any position in the classroom and change seats regularly; At home, children's desks should be placed outside the window where there is no obstruction, and desk lamps should be placed in the left front with soft light, such as incandescent lamps, preferably 25-40w.
In the meantime, direct exposure to the eyes is not advisable.
Zhang: (4) Correct bad posture. When reading and operating the computer, we should pay attention to keeping the distance between eyes and books at about 33.
A computer screen 35 cm away should not be less than 60 cm.
A computer screen 38 cm away should not be less than 70 cm.
Centimeter. Keep a correct sitting posture. Don't read while lying down or watch while walking.
Summer (5) If your eyes are dry, red, burning or foreign body sensation, heavy eyelids, blurred vision, or even eye pain or headache when watching at close range, it means that you have symptoms of visual fatigue. You should immediately stop watching at close range and do eye exercises. You can also use hot and wet towels to press your eyes to relieve visual fatigue. If there is no obvious improvement after the above treatment, you need to go to the hospital to see an ophthalmologist.
Zhang: 6) Try to play less games that need to be watched for a long time. In modern cities, students' games are mostly indoor entertainment, such as personal toys, game machines, computers and televisions. There are few opportunities to change their games and do more outdoor activities every day.

Zhang: This is the end of the quiz. In fact, to develop a good habit of using eyes, we should not only limit the time of using eyes at close range, but also use eyes intermittently. It is more important to develop good living habits, ensure adequate sleep time, and eat reasonably, especially the intake of essential elements. Experts also pointed out that eye exercises are the simplest and most effective way to prevent myopia.
Xia: The key to improve the quality of eye exercises lies in the accurate operation of acupoints. Everyone must cherish all the opportunities of eye exercises twice a day and do eye exercises seriously.
