Students in the second year of junior high school who have a vision of 4 7 0 5 in both eyes need t

Hello! Through the given visual acuity value of the child's vision is low, but low vision is not necessarily myopia, myopia is to be checked out through dilated eye refraction, it is recommended to give the child a dilated eye refraction examination, if it is myopia, it is recommended to wear glasses, the child's body is longer in the long time plus the eyes will be improved for a long time, glasses are now a corrector for the child, it will be the relaxation of the ciliary muscle of the child's eyes, thereby reducing the growth rate of the eye axis, that is, to control the development of myopia, Many parents think that the more myopia you have, the deeper your myopia will be, which is a wrong idea.

1. Myopia glasses can correct vision. Myopia eyes are not clear because distant light cannot be focused on the retina, but after wearing myopia glasses, you can obtain a clear image of objects, so that vision can be corrected.

2. Myopia lenses can reduce visual fatigue. Nearsightedness without glasses will inevitably lead to easy fatigue of glasses, and the result can only be to promote the deepening of the prescription. After wearing glasses normally, eye fatigue will be greatly reduced.

3. Myopia lenses can prevent and treat exotropia. When myopia is near, the adjustment effect of the eye is weakened, and the external rectus muscle of the eye exceeds the internal rectus muscle for a long time, which will cause eccentria of the eye. Of course, myopia with exotropia can still be corrected with myopia lenses.

4. Myopia lenses can prevent and treat proptosis. Because the eyeball is still developing, accommodative myopia is very easy to develop into axial myopia. In particular, in highly myopic eyes, the anterior and posterior diameter of the eye is significantly extended, and the appearance is manifested as proptosis, which can be reduced or even eliminated if myopia is corrected normally with glasses at the beginning.

If it affects the normal ability to see the blackboard, it is necessary to correct the vision with glasses, and the standard can not be relied on too much, and there is no need to wear glasses to see the machine. The key is to cooperate with the scientific ** to improve the naked eye vision and control the development of the degree.

If you can read the teacher's words clearly, you don't need it, and if you can't see it clearly, you can match it. Squint up and see clearly, too.

If you don't need to wear glasses in your daily life and don't have the habit of squinting to see things, you can do without them.

If you are used to squinting because of myopia, it is recommended to wear glasses. Because the pressure of squinting on the eyeball will add depth.

If it helps, hope.

In fact, you can live without glasses.

If you don't usually look at electronic products, you can do without glasses, it is recommended to wear anti-blue light glasses to protect your eyes, and anti-blue light glasses without prescription can also protect your eyes.

If you look at the blackboard or the normal vision range, squinting to see things, it is recommended to check carefully to avoid increasing the power, or you can't be sure what the power of the eye is, so there is time to rule out pseudomyopia to see how many degrees there are. Hope it helps.

Unaided vision does not indicate how many degrees of myopia you have, you must use the existing equipment to determine your myopia, and you are only 12 years old, it is best to go to the hospital for dilated refraction. If you don't wear glasses, you can listen to the advice of your ophthalmologist.

Vision can be corrected without glasses, and it can be corrected with a myopia ** device for a period of time.

Visual acuity is not necessarily proportional to diopter, and whether vision requires glasses is related to the following aspects:

1. Age: The vision of the elderly can be caused by cataract or diabetes, and it can also be refractive error. Teenagers have normal vision and are usually abnormal. Some children, such as preschool children, are around 4-5 years old, and their vision is mostly normal;

2. Disease such as ant disease: exclude some diseases, such as amblyopia, strabismus, etc., to determine whether myopia is caused by refractive error.

It is recommended that patients undergo an ophthalmology examination to rule out vision loss due to organic diseases, and to determine whether glasses are needed based on age.

Glasses culture fully reflects the cultural characteristics of a country and a nation, such as ideology, morality, values, beliefs, customs and habits, and develops with the development of culture in various historical eras. It is embodied in the form of a combination of material and art, through tangible touches. On the one hand, it reflects the progress of social civilization, and at the same time, it also reflects the wearer's identity, social status, ideology, hobbies, etc.

Lens culture. The cultural connotation of lenses is mainly reflected in the quality of materials, the size, curve, combination of lenses, and the exquisiteness of color and luster. In ancient times, the glasses used by emperors, officials, wealthy people and ordinary people were different, reflecting completely different cultural colors and connotations.

In modern times, all social strata such as industry, agriculture, commerce, learning, and soldiers, men and women use mirrors in different styles, all of which reflect people's ideological and cultural connotations.

Frame culture. The frame culture is also reflected in the quality of the material, the shape, color, and decoration of the frame, as well as the meaning. In ancient times, the frame was often engraved with patterns such as blessing, lu, longevity, and wealth, reflecting the value connotations of "blessing in front of you", "blessing and longevity", "prosperity in official luck", and "wealth in all seasons".

At the same time, the beam frame is often carved with the name of the store, the name of the person, the gold content, etc. According to the different social status and status, the frames used by emperors and dignitaries are mostly made of precious materials such as gold, silver, tortoiseshell, and ivory, while the glasses used by ordinary people are mostly made of copper, iron, steel, wood and other materials. The beam frame pattern of the glasses gradually transitions from the original arch bridge shape, door shape, city gate hole shape, and arc shape to a word shape, bamboo shape, and up-and-down beam shape; Beam card, side card, from moire, cat's head, tiger head to eagle head, two-point, plum blossom dot and other shapes.

Modern frames have further developed on the basis of ancient frame culture, and have become more colorful in form, design, decoration, patterns and colors, reflecting new values and aesthetics.

What I want to say is:

When I first got glasses (I just couldn't see the blackboard clearly in class), because I didn't understand, I was very big according to the refraction power, and as a result, my vision plummeted with the power of the mirror, because my vision would follow the height of the glasses.

Originally, I didn't support glasses, but you are a senior in high school and have a lot of study, so if it really affects your learning, you can get one. But, but ah——- there is also a saying that it is matched:

One: Presumably, if you sit in three or four rows without glasses, you can't see the blackboard clearly, if you can match it with a low degree (the kind that can see the blackboard clearly), and you can't match it according to the number from the optometry, so you may need to wear glasses for a long time.

2: If you can see the book clearly when you read and write, don't bring a mirror.

Three: If you can live without it, you won't bring it.

If the above three items are achieved, the university courses will not be too heavy in the future, and there is still a possibility that the eyesight will be restored.

Ten years from now, if you can look back at this reply, you will definitely be able to understand the feelings of a person who has never lived a life.

Glasses must be fitted, because the deviation of both eyes is too large, otherwise the damage to the right eye will be greater, and it is easy to form amblyopia.

If you want to match, I'm short-sighted.

1 Definitely matched.

2 It usually takes two days, so it's best to give the opticians plenty of time to do it carefully. The parameters of the glasses are more stringent.

3. Check the eye disease, optometry, pick the frame, pick the lens, pay, pick the glasses the next day, adjust the frame. Wear it away.

Wearing glasses is necessary in the following ways:

1. First of all, it is necessary to make it clear that wearing glasses for myopia can correct vision and avoid the occurrence of amblyopia, which is especially important for children before the age of 12. Because the light entering the eye of myopia cannot be focused on the retina, resulting in unclear vision, but after wearing myopia glasses, you can obtain a clear image of the object, so that the vision can be corrected.

2. Secondly, myopia lenses can reduce visual fatigue. If the vision is not clear due to myopia, the eye will increase the adjustment to achieve the purpose of seeing the object clearly, and long-term overadjustment will inevitably lead to the occurrence of visual fatigue, which in turn will deepen the myopia, causing a vicious circle.

3. Wearing glasses for myopia can prevent the occurrence of exophthalmosis. When myopia is near, the adjustment effect of the eye is weakened, and the extraocular rectus muscle acts more than the intraocular rectus muscle for a long time, which causes exotropia.

Your unaided eyesight is only as good as the left and right, where did you check your eyesight? Small is still a child, so you have to confirm that you are myopic to get the hospital dilated eye refraction, in order to know whether you are true myopia or false myopia, according to this vision may be false myopia, you rest well, in addition to some physical **, do some distance and moderate training may be recovered, if it is true myopia, your age group is more with or not, so it is better to wear glasses**.

It is relatively simple to pay for glasses, you have a good optometry in the hospital, he will let you choose the frame, and then choose the shelf, I think these things are more suitable for you to take the adults to do, maybe the glasses dispensed by the hospital are more expensive, then after the optometry to take the list to the optical store to match, that may be cheaper, in saying that your current prescription is very unstable, a small prescription may be good, or it may be deepened with the eyes, so there is no need to match the lenses, but it is a pity to change it after a short time, the glasses are very fast, the prescription is full, Half an hour for you to match out, it is best to check every three months, there is a number in the heart, if the degree changes, it is best to change the film quickly, do not support, a support will make the eyes tired, a tired may deepen fast.

Get a check-up first.

1 to the hospital to determine whether it is true myopia, if it is pseudomyopia, pay attention to her usual eye rest, generally pseudomyopia is caused by eye fatigue, usually watch TV and play computer time to control, do homework time also control, can not work for two or three hours in a row, can not be picky eater, look at the distance, to the park to see the greenery. 2. If you are already truly myopia, you need glasses, and it is better to have a seat in row 34, and there is no need to be very front. It is also necessary to pay attention to the sitting posture, not to write with the head tilted, which can easily cause anisometropia, that is, the vision of the left and right eyes is different.

Eat more foods that are good for your eyes, fish, seafood, exercise more, control the time you spend with your eyes, and don't let your eyes be overloaded all the time.

It will be reached at the age of eleven, and it should be matched, and if it is not matched, it will deepen quickly. The steps are basically to look at the eye chart first, and then carry out accurate computer refraction, after determining the current vision, he will give you a frame (model), insert the spare lenses that are suitable for you, let you get used to it, if there is not much discomfort, go to choose the lenses and frames, and then, they polish the lenses, and finally install the lenses on the frames, and it is completed, and the last very important process: payment The whole process takes about half an hour.

Is it better to wear glasses all the time, or is it better to take them off and wear them?

Myopic glasses are placed in front of the patient's eyes to correct distance vision. Because the myopic eye can see near objects clearly, in order to maintain a certain adjustment ability of the ciliary muscle of the eyeball, it is better for patients with low myopia to take off and wear it, that is, wear glasses when looking at distant objects, and do not wear glasses when looking at near objects. This does not contribute to the development of myopia.

Since vision can fluctuate due to the influence of physical health, light and darkness, etc., people who wear myopia glasses, when their vision decreases slightly, should not rush to deepen the lens power, but should look for the cause of vision loss, and observe for a period of time, otherwise the eyeball's focusing system will adapt to the new combination of deep lenses.

However, for myopia with astigmatism, it should not be taken off and worn, because after taking off the glasses, when looking at a close target, due to the existence of astigmatism, the object image is still not very clear, and it will cause visual fatigue and promote the development of myopia.

For patients with high myopia, because the far point is too close to the eyeball, if you take off your glasses when looking at near objects, it is very inconvenient to see things, and the convergence of the eyeballs cannot make the visual axis of the two eyes trade at such a close target, which is easy to cause the disuse of one eye, and the convergence effect occurs together with the adjustment effect, which can promote the further development of myopia. Therefore, for patients with high myopia, they should also wear glasses often and cannot take them off. However, in order to maintain a certain adjustment effect of the eyeball, patients with high myopia should wear a pair of bifocal glasses (commonly known as bifocal glasses) when looking at near objects, and use the correct power of the upper part of the lens when looking far away, and the shallow myopia power of the lower part of the lens when looking at near objects.

Myopia is only corrected, and it should not be corrected in place. Check it again to see if it can be corrected.

You can do without glasses, but you must pay attention to eye hygiene, otherwise, your vision will go down. Myopia, the name of a disease in traditional Chinese medicine. It is the eye in a state of accommodative relaxation, and the focus of parallel light rays refracted through the refractive system of the eye falls in front of the retina.

Ancient medical books have long understood this disease, called eye can not farsighted, also known as can near cowardice, to the "eye Jing Dacheng" began to call myopia. Born by congenital conditions, those with a high degree of myopia are also known as myopia. The occurrence of myopia is related to many factors such as genetics, development, and environment, but the exact pathogenesis is still being studied.

To identify true and false myopia, in addition to going to the hospital for optometry, the simple way is to hang an international standard eye chart at a distance of 5 meters, first determine the visual acuity, and then wear 300 degree reading glasses, look into the distance, the cloud-like scene will slowly appear in front of you, take off the glasses after half an hour, and then check the eyesight, if the vision is enhanced, it can be considered as pseudomyopia; If your vision is still declining or declining, you can do it once a day for three consecutive days, and if your vision still does not improve, you can determine that you are truly myopia.
