1. Intuitive description: Tell the eyes intuitively from the function
Eyes are like a camera. The * * * interaction between the lens and the cornea is equivalent to a convex lens, which focuses the light from the object on the retina to form an image of the object. Nerve cells on the retina are illuminated by light, and when this signal is transmitted to the brain, we can see objects. The eye changes the shape of the lens through the ciliary body: when the ciliary body is relaxed, the lens is thinner, and the light from distant objects just converges on the retina, so the eyeball can see the distant objects clearly; When the ciliary body contracts, the lens becomes thicker, and its ability to deflect light becomes greater. The light from near objects converges on the retina, and the eyes can see the near objects clearly.
Myopia can only see the near objects clearly, but can't see the distant objects clearly. The reason for myopia is that the lens is too thick, the refractive power is too strong, or the eyeball is too long in the front and back direction, so the light from a distant point converges in front of the retina, and it is not a point but a fuzzy spot before reaching the retina. < P > Using the characteristic that concave lenses can make light diverge, putting a concave lens in front of the eyes can make the light from distant objects converge on the retina.
2. The window of the mind always finds a place through the straightforward expression of the eyes. Some of them imply happiness, some reveal melancholy, and some are elusive ...
Something can be described by this ...

Today, I was lying on the edge of the grass again, forgetting the world and myself in infinite silence. Before my eyes, the grass grew bigger than ever, and it became a big forest. A little ant walked around alone and found a small piece of bread crumbs. I think it must be a clever cook, and came out to find some. But it couldn't move, so it turned and walked back to the cave. Soon, the ant chef brought out several porters, and Qi Xin worked together to move the food in. Tonight, they had a sumptuous dinner! I seem to smell the rice fragrance of ants. I want to go in and share it with them, but I'm afraid of scaring these elves. Ants live a regular life, and they do their own things: the little ants are at school, the teacher is teaching, and their teachers and students are so serious and absorbed. When the little ants are at school, their parents are working and working. Ding Rinrin ... When the school bell rings, the little ants all go home. When they get home, the little ants report to their parents what they have learned in the day. Parents may criticize them or praise them. A little ant who looks very proud, I think it must have got good grades in the exam. An ant robber stopped an ant resident viciously, just as the ant policeman passed by and caught the ant robber. I think the ant policeman must be very happy because it did a good thing for the people. Smoke was raised in the farmhouse yard. The barking of the puppy brought my heart back. I would like to take your hand and go for a walk in the kingdom of ants. Today, I came to the ant cave with great interest and saw them bustling. Ants stood in rows and rows, ready to do exercises. Suddenly, the ant team was out of order and scattered. They ran and ran, constantly bumping around, and a huge ant bumped into a petite ant. The petite ant couldn't climb any further. A large group of ants swarmed over, lifted the petite ant and walked away. Their mouths kept comforting the little ant. The little ant was grateful and repeatedly said thank you. My eyes followed the ant's path to explore, and I saw the unity, mutual assistance and friendly quality of the ant. I got a lot there! I wandered for a whole morning, and my heart didn't come back until Grandfather Sun laughed harder. Seeing that they were so United and friendly, I was completely confused. How much wisdom was hidden in the minds of ants? How many qualities of ants are worth learning? What is the power that makes them so United? I am completely immersed in the ocean of ants. When the ants go home, there is a sound of ants eating in the cave. I am back to nature in this ocean of wisdom. (1) Locusts and grasshoppers "a green robe with six thin legs, which are covered with thorns and jump three feet high". Hey hey, guess what this is? I don't know, it's Mr. Locust, the "sovereign" of the famous pest kingdom. Because I don't know him very well, I brought him and his follower, the grasshopper, back for research. I also gave him an interesting unused name, the Green Train. There are two flexible antennas on the front of the Green Train. It moves as if it were going to eat me. In the middle of this terrible jaw, there is a lovely "cherry three-petal mouth". There is also a bell-like pattern on its abdomen, not to mention how weird it is. I think it may be used to scare people. The biggest feature of the "green train" is that it has six legs, four of which have a round sucker on each front leg, and eight. There are still many thorns on the calf. If you look closely, it really looks like handfuls of saws. According to my mother, locusts and grasshoppers are small, but they are all super villains. They especially like to eat rice, wheat, sorghum, corn and other crops. Where swarms of locusts have swept through, the vast green space will become a wasteland, and the crops will be eaten up, and almost everything they can bite is spared. This is really terrible. (2) "Colorful Skirt" This time, I will introduce a new protagonist to you. As soon as you see it, you will definitely think of Cinderella in fairy tales. It is wearing a dark gray dress, but it is just a cloak. As long as it opens its wings, it will surprise you. It turns out that there is a colorful "dance dress" hidden inside it! It is a mysterious visitor to my family-an unknown vagrant, so I gave it a nickname-"colorful skirt". It looks like a butterfly, but I think it should be with locusts. It has no good heart and must be a wolf in sheep's clothing. The beautiful "dancing dress" of "colorful skirt" is really charming, but as long as you look carefully. Hey hey, isn't it scary enough? There are many colorful dots embedded in its dancing clothes, including red, black, yellow and white, which are dotted on the dark blue background. It is really beautiful, so whenever other insects pass by, it can't wait to show off its dancing clothes. But at the same time, it is so stingy. Look, I haven't seen enough. It has put away its dancing clothes. Hey! I can't help it. But don't worry, I'll tell you another little secret-the girl with colorful skirts can't fly, but she can only hop and hop at ordinary times. Ha, you see that she is unhappy now and is worried about it. (3) After reading the topic, you must want to know what "hopping beans" are. Um ... Not another ... mysterious visitor, is it? Ha ha, yes, it's already the second guest, and I stuck it on my clothes when I was playing in the mountains. The body of' Tiaotiaodou' is in an inverted triangle, and its coat is green, just like the last mysterious visitor's colorful skirt. The coat is unremarkable, but the shirt inside is very beautiful. Its shirt is red on both sides, with a blue and a white lace in the middle. Interesting. 3. How to write my findings
Recently, I found that my aunt next door kept a little white rabbit. It had a short tail and snow-white hair, which seemed to be covered with a fur coat, because its ears were long and its hearing was very sensitive. At this time, I found that the eyes of the little white rabbit were different from ours, and it seemed like two rubies were embedded in her face. So I asked my aunt, "Aunt, little white rabbit. Aunt thought for a moment and said, "I don't know. Ask someone else!" " When I got home, I asked my parents why the rabbit's eyes were red. They said they didn't know. At this moment, I remembered a book "1, Why" my mother gave me. I found it out. Finally, I found the answer on a page. It turns out that the color of rabbit eyes is related to the color of their fur, and the eyes of white rabbits are transparent. Then why do we see that the eyes of small white rabbits are red? This is because the bloodshot (capillaries) in the eyes of white rabbits reflect the external light, and the transparent eyes appear red. The eyes of gray rabbits are gray. Rabbits have various colors, and their eyes have different colors. That's because there is something called pigment in their bodies. Rabbits with gray pigment have gray hair and eyes. The rabbit with melanin has black hair and eyes. The rabbit has no pigment in its body, and its eyes are colorless. The red we see is the color of blood, not the color of eyeballs, so its eyes are naturally red. 4. What composition did I find with my eyes? < P > People often say that the eyes are the windows to the soul.
If you lose your eyes, the whole person will live in a dark space, and life will have no fun. So we should cherish time, let us see the world with our eyes and all the beautiful things in the world.
In spring, I see a vibrant spring scene. I saw all living plants and animals open their sleepy eyes.
The grass sprouted from the wet soil unconsciously, and the mountain came back to life! It wears a green coat. All kinds of colorful flowers are blooming together. The cherry blossoms by the river are blown by the spring breeze, and the petals are scattered on the sprinkling surface, which looks like a blue belt with many pink spots on it.
When people see this scene, they will clap their hands and praise it. I saw Miss Qiu come quietly.
Because the leaves turn yellow and the fruits are ripe, when the autumn wind blows, the maple leaves fall, just like a few little girls dancing. Clusters of chrysanthemums compete for beauty, including red, white and yellow, with different shapes and colorful colors.
I went to the market, which was also very lively. Every household hung corn cobs, some hung on the treetops, some basked in their own homes and some piled on the ground. Chickens are pecking at rice, animals are laughing, and all eyes are busy.
How rich the autumn colors are! Even a glance at this charming scenery will surely fascinate you! Ah! I want to see the first corner of the motherland with my big bright eyes. 5. The discerning eye wrote 37 words < P > The eagle flies briskly and looks down at the sky; Fish is shallow and appreciate the bottom of the water. Peony is elegant and impressive; Chrysanthemum is elegant and lofty, far from the secular. Looking at everything with the eyes of discovery, we can't help but express our feelings of freedom in all kinds of frosty days, or tell a salty and salty taste.
Be good at discovering and lead yourself to appreciate different wonderful things with your eyes. That "Spring and Snow in Qinyuan" depicts the scenery of the northland, and the snow in Wan Li is frozen thousands of miles away.
