Hello! Today we will talk about the eyes. Agree. Everything that we see around us: blue - blue skies, spacious wide fields, flowers of fabulous beauty in a clearing, our loved ones. We can look into the eyes of our near and dear ones. This is all with the help of the organ of vision - the eyes. So let's think about how to behave so as not to damage the eyes, keep them healthy and beautiful until old age!
It is interesting! The most vigilant of the animals in our area is the eagle. He flies high and sees far. Especially the eagle sees its prey well. And at night, the owl sees best of all. The chicken sees the worst at night. Therefore, the disease, when a person sees poorly at night or does not see at all, is called night blindness.
Health is one of the most acute problems of modern life. One of the organs that we must protect is the eyes. Take care of your eyes!
We see our eyes differently ... When fun is in them, when there is a thunderstorm! When they are bright as a summer day. When they are dark, like a shadow of the night! what are the eyes?
Look at the children's faces and into their eyes. Which eyes do you like best?
Conclusions: Indeed, the eyes are different. They are different for every person. Eyes are different color, size, expression. And the expression of the eyes depends on the mood of the person. If everything is good in life, then the eyes shine, shine, sparkle. But if a person is ill, then we immediately, by his eyes, determine that he is ill, that this person needs help.
Gaseous, liquid, solid and sharp objects: dangers around us
Say yes or no? when I read and write I sit straight at the table; I read lying down; when I read and write, I put the lamp on the left; when I read and write, I put the lamp on the right; I watch TV as much as I want; I watch TV no more than 40 minutes; I keep the right distance when writing and reading; I run with sharp objects in my hands; I follow the rules of reading and writing; I throw sharp and hard objects at my comrades; I rub my eyes with a dirty hand; I do gymnastics for the eyes; I look at a bright light for a long time; I always wear dark glasses; I follow the daily routine. eye care
What to do when people are born with sore eyes? There is a science called "Eye Microsurgery", where eye doctors work. Some diseases can be cured with the intervention of doctors. These are diseases such as strabismus, myopia, hyperopia, conjunctivitis, retinitis and other diseases. Eyes can be treated not only with medicine or surgical intervention but also with glasses. When a doctor prescribes glasses to a person, you should not be ashamed to wear them. I want to tell you a story that happened to my friend when she was a child.
Judge for yourself why this happened? There lived a girl. She grew up and began to go to school. One day the eye doctors came to the school to check the eyes. They told the girl that in order to cure her eyes, she had to prescribe glasses and put them on in class. The girl's mother brought her glasses. The next day the girl came to school wearing glasses. When she entered the classroom, classmates began to laugh at her and called her a bespectacled man. The girl ran out of the classroom, ran and threw her glasses into the hole. Because she thought it was embarrassing to wear glasses. At home, she told her mother that she had lost her glasses. Guys, did you like what your classmates did? Why?
Vegetables and fruits are solid vitamins! Did you know?
Guys, watch out! Guys! Let's take care of our health!
Charging for the eyes Exercises for the eyes. 1. Blink 15-20 times. 2. Look right, left, up, down. 3-5 times. 3. Roll your eyes first to the left, then to the right. 3-5 times. 4. Blink 10 times. 5. Close your eyes firmly, pressing your eyelids against eyeballs. 6. Stand by the window. Mark a point on the glass opposite the eye. Close one eye with your hand. Another 5 seconds, look at the point, then out the window. 6-8 times with each eye. 7. Raise your finger to eye level. With one eye closed, look at your finger with the other, then into the distance. 6-8 times. 8. Blink 20 times.
Performed to the music of "Blue Wagon" We wish everyone today, Take care of your eyesight. Your kind and clear eyes Let the world turn into miracles. Rules, rules Reading and writing, Companions are important In life forever. Kind, brave, Important, wonderful. Everyone, everyone We need eyes.

I will help myself!”, images of an eagle and an owl, riddles about eyes, proverbs about eyes, a mirror, vocabulary work on the board.
Event progress:
How does a person communicate with environment? What helps him in this?(With the help of 5 senses - touch, sight, hearing, smell, taste). What kind external bodies people responsible for it?
In order to be healthy, you must know your body well and love it. Let's memorize a few words, they will help us stay healthy.
I will keep my health
I will help myself.
And what we are going to talk about today, you guys will find out if you guess the riddle:
Two brothers live across the road, do not see each other?(eyes)
Which animal do you think is the smartest? It is well known that the most acute vision at eagle . What do you understand by the expression "sharp vision"? he floats on high altitude and from behind the clouds looks out for its prey on the ground.(showing a picture of an eagle). Sees best at night owl. She can easily find a mouse in the dark(showing a picture of an owl). But what can be said about the mole? Why is he blind?
Man is not as sharp-sighted as these birds. Can the eyes be called the main helpers of a person? Prove it. The eyes help to see everything that is around, to distinguish and recognize objects, their color, shape, size. Turn around to face your neighbor, see what beautiful eyes in a person. How do they talk about eyes to convey their beauty?(beautiful eyes, clear, clean, huge, cheerful, sharp-sighted, etc.)What is the color of a person's eyes?(brown, blue, green, gray, blue). What size are the eyes? Where and how are the eyes located?(Showing the poster "The structure of the eye")
What can be found in the eye when it is examined closely? Yes, this colored ring is called "iris". It affects the color of our eyes. The iris is covered by a transparent thin film - the "cornea". In the center of the eye we see black dot. It expands and contracts. This is the "pupil". It controls the amount of light. Rays of light pass through the pupil and lens and are collected on the retina of the eye. Further along the nerves, signals are transmitted to the brain, and a person sees what he looks at.
Conducting an experiment with a mirror
Bright light - the pupil narrows, weak - expands. The tissues of the eye are very delicate, so the human eye is naturally well protected.
What parts of the eye help protect?(Eyelids, eyelashes)
Guess the riddle:“Under the bridge - a bridge, under a sable - a sable, two sables played out”(brows and eyes) . Eyebrows, eyelashes and eyelids are not only for beauty. They protect the eyes from dust, wind and sweat. Why does a person need tears?(reasoning of children, conclusion - protection from dust). I propose to open workbooks and draw a diagram - the structure of the eye, do not forget to point to all parts of the eye.
Proverbs about eyes
From the master's eye and the cat grows fat. In its nest, even a crow will peck out the eyes of a kite. Dashing eyes and children are numb. Pig eyes are not afraid of dirt. He who has no desires has no eyes. True knowledge is not evident. It is better to be blind with the eyes than with the mind. Open your eyes quickly, open your mouth slowly. Do not praise in the eyes, do not reproach for the eyes. The eyes are to see, the mind is to recognize. The eyes are the mirror of the soul. Eyes are burning, eyes are listening. Your eye is vigilant, you don't even need forty. Eyes look, and hands do. Your own eye is a diamond, and someone else's is glass. You can see the person's eyes. One eye to see far. Brown eyes - brave people, gray eyes - brave people. Some eyes both cry and laugh. The tooth is rare, but the eye marks. Eagle eyes and mosquito wings.
Fizminutka
On the desk of each is a memo "Gymnastics for the eyes." Review the suggested exercises carefully. Why do you think you need to do exercises for the eyes? Correctly, from daily gymnastics, not only the muscles of the body, but also the eyes will be strengthened.
We perform a set of exercises for the eyes standing at the desk
In the end, was it difficult? How long did gymnastics take?
Anchoring
Let's play the game "Helpful - Harmful". If you think the phrase is correct, clap your hands; if not, cross your arms over your chest. So,
- read lying down, at dusk;
- look at a bright light;
- protect eyes from shock;
- watch TV closely;
- wash eyes in the morning;
- rub your eyes with dirty hands;
- read sitting;
- eat healthy food, vitamins;
- contact an ophthalmologist;
- perform gymnastics for the eyes during lessons, at home;
- follow the daily routine.
What can cause a person to lose their sight? Is life easy for blind people? How do you feel if you see a blind person? What should be done? What do visually impaired people wear?
Scene: “Galya is a student”
Participants: mother, student Galya, doctor, author.
Student 1. Our Galya has grown up. She went to first grade. Little Checkmark began to learn. A good girl shouldn't be lazy. Little Galochka tried with all her heart, bending low over the new notebook. The little Check mark brought out the sticks - she leaned sideways, helped with her tongue. Curved like a question, as if writing Galin's nose!
Student 2. Galya's mother says: - Who, Galya, is sitting like that? Sit up straight, breathe more evenly, do not plow a book with your nose. Don't bend, do you hear? Head up!
Galya and her mother disagree:
Student 3. - I see everything perfectly! If you sit otherwise, do not read the tasks.
Student 2. Galya is going to the fifth grade ... He ran a year after a year. Then the relatives saw: Galya often screwed up her eyes. And, sitting on the first desk, Galya barely sees the board.
Student 3. - What they write there - you can’t understand, you can’t make out the words.
Pupil 4 . Galya does not see well in the distance, and the doctors said: “It's a pity, you yourself are to blame for this. This is the reason for your troubles: you held the book close, you bowed low to the letter. You crocheted over the notebook at the table. So I became short-sighted -
Together : This is also science to others!
Let's deduce the rules of careful attitude to vision together:
* wash your face in the morning;
* watch TV no more than 1-1.5 hours a day;
* sit no closer than 3 m from the TV, away from the computer monitor;
* protect eyes from foreign objects;
*when reading and writing, the light should fall on the left;
* eat vitamins, carrots, onions, sweet peppers, tomatoes, parsley;
* daily exercise for the eyes;
* strengthen the eyes, looking at the sunrise or sunset.
do not grieve. Over time, glasses can improve vision;
Take care of your “second eyes”, wash and wipe often;
Keep your glasses in a case
· do not put glasses down;
Take pictures while playing sports;
Do not pay attention to fools who tease.

SMELL
TOUCH
The pupil regulates the amount of light
if there is not enough light, it automatically expands,
if there is enough light, it shrinks.
We conclude:
Eyes see different
image,
but the brain combines and makes a single image.
We conclude:
This is due to the fact that the cones do not work in the dark, and the rods begin to work 200-400 times stronger and perceive light better. Therefore, in the dark we see the appearance of an object and do not see its color.

Methodical development class hour on the topic: "Take care of your eyesight"
Prepared by teacher Abralava Svetlana Sergeevna.
Goals: instilling skills healthy lifestyle life; familiarization with the basic rules of eye care in order to maintain good vision; formation of the need for personal hygiene, proper and regular care for their appearance and health.
During the classes.
1. Creating an atmosphere of psychological comfort.
(On the background music "Morning" by E. Grieg)
Guys, look what a great morning this is. Let's greet the world around us and each other.
Hello golden sun! (draw a circle with your hands)
Hello blue sky! (arms up, wave hands)
Hello free breeze! (wave hands in front of face)
Hello little oak tree! (raise hands up and wave them)
We live in the same region - I welcome you all!
2. Actualization of students' knowledge.
Now we said the word "hello", but what does it mean?
Have you ever wondered why the greeting of people includes wishing each other health? (children's answers are heard)
Health is the greatest value for a person.
What does it mean for you to be healthy? (children's reasoning)
3. Reporting the topic of the lesson.
Today we will talk about the most valuable human organ, from which we receive almost all information about the world around us. And what exactly will you learn by guessing the riddle:
Two Yegorkas live near the hill,
They live together, but do not look at each other.
Guessed?
What associations do you have with this word?
Define the word "eyes".
The theme of our lesson is “Take care of your eyesight”, and the motto will be the following words: “No one will take care of you better than yourself.” (slide 1)
4. Discovery of new knowledge by children .
Eyes are an amazing gift of nature. With the help of the eyes, we see objects, perceive their shape, size, color. The eyes help us determine whether an object is moving or stationary. None of the sense organs can give a person as many impressions as the eyes give.
Look into each other's eyes. How beautiful they are!
How do they talk about eyes to convey their beauty? (children's answers are heard) - slide 2
A) Tasks in groups.
In ancient times, people understood the importance of the organ of vision for the perception of the world, and this was reflected in folk wisdom.
Each group does the following tasks:
Collect proverbs and explain the meaning. (The eyes are afraid, but the hands are doing. Do not believe your ears, but believe your eyes.)
Explain phraseological units. (Throw dust in the eyes. Fear has big eyes. Callus on the eyes. Eye-diamond.)
Riddle about eyes with missing words. Insert words and guess.(Two Yegorkas live near the hill, live together, but do not look at each other.
Children's responses are heard.
Proverbs, riddles and phraseological units are folk wisdom, which allowed us to make sure once again that even in ancient times people thought about maintaining their health.
Now we will give rest to our eyes, and perform an ophthalmic physical minute.
We close our eyes, these are miracles. (close both eyes)
Our eyes rest exercises perform (continue to stand with eyes closed)
And now we will open them, we will build a bridge across the river. (open eyes, draw a bridge with a glance)
Let's draw the letter O, it turns out easily. (They draw the letter O with their eyes)
Raise up, look down, (make eye movements)
Let's turn right, turn left, (eyes look to the right, to the left)
Let's start again. (Children sit in their seats)
B) Statement of the problem situation.
What made me see this beauty? (slide show 3-9)
And when the world appears before us in such an image? (slide 10)
Or like this? (slide 11)
Scary, right?
Children's responses are heard.
What is the cause of visual impairment? (children's reasoning)
Summing up (slide 12)
It turns out that the eyes are the most vulnerable organ. After all, we constantly make him work.
Therefore, it is not always possible to save good vision and the person is forced to wear glasses.
What advice would you give to children who wear glasses?
And now let's play the game "Helpful-harmful". If you think the phrase is correct, clap your hands; if not, stomp your foot.
Look at the bright light
Protect eyes from shock
Watch TV up close
Wash your eyes in the morning
Rubbing your eyes with dirty hands
Eat healthy food, vitamins
Contact an ophthalmologist
Do eye exercises
Follow the daily routine
C) Work in groups
Group 1 will draw up the rules of careful attitude to vision
Group 2-syncwine on the theme "Eyes"
3 group - physical minute for the eyes
Listening to children's answers. We will hang the rules for caring for vision in the classroom, as well as print and give to students elementary school so that they can preserve this priceless gift that nature has given us.
5. Fixing.
And now listen to the advice of your classmates, who in poetic form will complement our advice on how to maintain eye health.
When they want
Take care of your eyes.
Listen! When they want
So that the thing serves us without a deadline,
No wonder people say:
"Keep it like the apple of your eye!"
And so that your eyes, friend,
Could last for a long time
Remember two dozen lines
On the final page:
It's very easy to hurt your eyes...
Do not play with a sharp object!
Not three eyes, do not clog,
Do not read a book lying down;
Can't look at bright light
It also damages the eyes.
in the House there is -
I won't blame
But please don't go
to the screen itself.
And don't look at everything
And the shows are for the kids.
Do not write, bowing low,
Don't keep your textbook close
And over the book every time
Don't bend like the wind
From the table to the very eyes
Must be
!
I want to caution:
We all need to keep our eyes peeled!
6. Summing up. Reflection. (slide 13)

Do you have good eyesight?
What are some ways to heal your eyes?
What vision correction methods do you know?
Recommendations for junior schoolchildren for eye health and vision correction Circular movements. Make circular motions open eyes: first clockwise, then counter-clockwise. Movement in straight lines. Intensively move your eyes horizontally: left and right, and vertically: up and down. Blink. Squeeze and open your eyelids vigorously. Diagonals. Direct your gaze to the lower left corner, that is, look as if at left shoulder and focus on that point. After three blinks, repeat in right side. Relaxation. Close your eyes tightly and try to relax. To perform this exercise, it is worth remembering some pleasant moments in life. Exercises for the eyes How is the eye? In front of the eye, the iris (colored part) is visible, surrounding a small round hole - the pupil. When you look at an object, light is reflected from it and enters your eye through the pupil, passes through the crystalline lens that focuses the image, and finally reaches the retina. The retina is a kind of screen of nerve endings, on which the image is turned upside down. Retinal cells convert light signals into electrical signals and transmit them along optic nerve into the brain; here the information is processed and the visual image is recognized.  Rules for watching TV 1. You need to sit right in front of the TV, just holding your head straight. 2. It is useful to blink frequently and breathe deeply. 3. Eyes should "walk" around the screen, you should not look at one point. 4. Relax while watching TV by briefly closing your eyes or covering them with your palms, let the muscles rest and the retinal nerves strengthen.
