Is it normal for a child to have a vision of 4 0 and a child to have a vision of 5 0

My eyesight is mild myopia, not that it is particularly normal, the normal is five, it is particularly normal, that is, it is already a little mild myopia, for the sake of safety, you had better let the child pay attention, or give him a pair of glasses, in this way, the power will no longer be long, or the tender degree will grow higher and higher.

Visual acuity mainly reflects the visual function of the macula area of the fundus. It is divided into distance and near vision. The distance of the distance visual acuity examination is 5 meters (meters for reflectors), and the distance between the eyes and the eye chart is the same height, and the visual acuity is standard.

The distance of the near vision examination is 30 cm, the visual acuity is normal, the right eye is checked first and then the left eye, and care is taken not to compress the eyeball when covering the eye. Myopia: Distance visual acuity Near visual acuity is normal.

It mostly occurs in adolescence, and genetic factors have a certain influence, but its occurrence and development are closely related to insufficient lighting, improper reading posture, and long working hours in close proximity. Visual field: also known as peripheral vision, optic nerve, retina, and central nervous system can lead to defects in part of the visual field.

It is normal for a child to have abnormal vision.

Your child's eyesight. Is it normal? It's definitely not normal.

Hurry to the ophthalmology department of a regular hospital. Check it out. Hurry up and correct your child when he or she is young.

It's not easy to treat when it's late. Don't delay your child's eyesight and go for treatment as soon as possible.

The visual acuity in the new eye chart is equivalent to about 250 degrees of myopia, which is mild myopia. Mild myopia is generally myopia within 300 degrees, myopia within 300 degrees, and it is not recommended to wear glasses if it does not affect vision, especially for children under the age of 18. Children under the age of 18 are still in the period of vision development, and the adjustment of the eyes is strong, and mild myopia can be recovered.

It is abnormal, generally the above is normal vision, and it is already myopia.

It's not normal, it's normal.

Does your child have normal vision? This one. Slightly worse but not too much of a problem. It should be normal, the best eyesight.

Do you feel that your vision is normal? The normal vision of the average person is, needless to say, it must be myopia.

It's a bit low, but it's normal to be five o'clock.

Your child's 10:00 zero eyes, he is nearsighted, normal eyes are in. Let's take it with you.

The child's vision is normal. If the visual acuity does not reach 50, an optometry test is done first to determine if there is a refractive error. 1) If there is a refractive error, it is necessary to use cycloplegic agent to refraction the eye after the eye to determine the true refractive status of the child; 2) If there is no refractive error or vision cannot be corrected with lenses, other tests are needed to determine the cause of abnormal vision (such as congenital cataract, amblyopia caused by various reasons, etc.).

Wishing you good health.

Hello, the eyesight is normal, but usually need to control the time of the child to look at the mobile phone, computer or TV, take the child to exercise outdoors, the child reads, writes for more than an hour, let him rest for ten minutes, and try to look at the distance when resting.

If we usually pay attention to observation, most of the children around us are myopia, due to the high incidence of myopia in children, many parents also attach great importance to the care of their children, now many children are often exposed to computers and televisions and other electrical appliances with strong radiation, long-term exposure to the radiation of these electrical appliances, eyes are also prone to myopia, so in order to avoid the phenomenon of myopia in children, parents should control their children's exposure to these electrical appliances, so, are children's eyes normal? Let's find out.

Step Method:

1 The child's eyes are completely normal if they are, and there are many cases where the standard is taken to define the range of normal vision, and the child's eyes are completely normal if they are, so to maintain the child's vision, it is necessary to pay attention to daily care, so that the child should use his eyes correctly, and do not watch TV and computer for a long time.

2 Children's eyes are normal vision, vision and eye power does not have an accurate conversion relationship, eye myopia is divided into pseudomyopia and true myopia and mixed myopia, in fact, many parents once found that their children have myopia, they immediately give their children glasses, which is very incorrect, you can choose a reasonable way to correct myopia and control the growth of myopia.

3 normal vision standards, the above is regarded as a normal phenomenon, below can be myopia, may also be farsightedness or other diseases, whether it is myopia, need to pass the optometry results shall prevail, parents should take their children to a regular medical institution for optometry examination, the general vision reaches, should belong to the normal vision range.

Precautions. In order to avoid the phenomenon of myopia in children, parents must pay attention to let their children protect their eyes, eat more foods that are beneficial to the eyes, develop good habits, supplement more vitamin A can increase the finish of the cornea of the eyes, make the eyes bright, eat less sweets and high-sugar foods, and do not contact computers and televisions and other electrical appliances with strong radiation for a long time.

If this is the result of the examination after the dilation of the pupils, it is true myopia, which is mild myopia, and it requires glasses, and the prescription will increase in the future. Usually pay attention to rest, don't stay up late, keep an appropriate distance from books when studying, look into the distance, and do more eye exercises. If you can afford it, you can wear orthokeratology lenses.

3-year-old children, vision can not reach a point zero, children are born with a certain reserve vision, that is, farsightedness, as the age increases, the vision is slowly growing, the degree of farsightedness becomes smaller, growing to about 10 years old, normal vision, can not just look at the eye chart, do a computer refractive examination, to see if there is amblyopia, or others, if it is amblyopia to wear glasses early ** It is okay to wear glasses for a few years, go to the hospital to check it.

It's severe, about 250 degrees to 350 degrees.

The visual acuity is significantly lower than the normal range, and if the vision loss caused by the refractive error is completely different in different people. Everyone's eye adjustment ability is different, completely different from person to person, so if you want to know whether your eyes are myopic and what the degree of myopia is, you must go to a regular hospital for an optometry examination to accurately understand the degree of myopia.

Myopia is not proportional to visual acuity, it is not a parallel correspondence, and it varies from person to person. For example, with the same vision, some people have a myopia of only more than 100 degrees, some people will have 300-400 degrees, and even some people will have astigmatism, etc., which is not the same, or they have farsightedness. Therefore, just looking at vision, you can't infer whether it is nearsightedness, farsightedness or astigmatism.

If the visual acuity is found to be lower than that, as is often said, the next step is dilated refraction. If you are over 40 years old, you can do without dilating your pupils, but under 40 years old, especially in children, have strong refractive adjustment ability, it is recommended to dilate your pupil refraction, which can overcome pseudomyopia and get the accuracy. The optometrist will prescribe glasses according to the prescription and take the prescription to dispense glasses.

Need to be slow down. Because some abnormal manifestations of the eye will be covered up after pupil dilation, it is best to go to the hospital for examination before deciding whether and how to dilate the pupils.

Generally speaking, the normal vision of children aged 6 and above is at least at or above, if you can't achieve this vision, then you should consider whether you have myopia!

Vision is about 150 degrees myopia, you need to wear the right glasses, and then you need to pay attention to:

1. Pay attention to the time you spend with your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and moxibustion acupuncture points of Chinese medicine, combined with jujube Kuanhui medical sports spike lifting, which is a scientific method to protect eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to eye nutrition.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

Regular check-ups are due to the fact that children's eye structure, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content that can be examined is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.

Usually many parents consult: the child's vision is found in the screening, and I don't know if it is low or normal?

This problem needs to be divided into two aspects.

Let's start with normal vision in children. Approximately equivalent to the visual acuity, whether the vision is normal, usually the normal vision standard for children around 3 years old, the normal vision of 4-year-old children, and the standard of normal vision for 5-year-old children. Therefore, the standard of normal range of vision for children of different ages is also different.

Second, if a child aged 5 and above has a child's vision, first of all, we can determine that the child's vision is abnormal, belonging to a kind of low vision, what causes this low vision, most of them are due to refractive error or amblyopia, and it is necessary to go to the hospital for examination, because any myopia, farsightedness, astigmatism and amblyopia will cause the problem of low vision in the child, and we need to go to the hospital for further diagnosis through dilated eye refraction. If you have myopia, you need to tell if it is pseudomyopia or true myopia, or if the child is just a short-term vision loss caused by eye fatigue.

For myopia, astigmatism or farsightedness, glasses can be worn to improve vision; If it is amblyopia, some should be covered and amblyopia training, so that the vision can return to normal as much as possible.

Yes. The E-word eye chart is the emmetropic eye (normal) if the ankle vision of both eyes is above. The visual acuity comparison table is as follows:

During the examination, the light source shines on the watch, but the reflection should be avoided, and the person should hold the near vision chart in front of his or her eyes, and move it back and forth until he finds the smallest size he can see. If you can read the number 1 character or time, let it gradually move closer until the handwriting begins to blur. The place that can be seen clearly before it is blurred is the near point, and the distance between the near point and the cornea is the near point distance, which is measured in centimeters.

Recommendation: Consider early myopia, which can be determined by refraction. If the vision is low due to myopia alone, it can be improved with targeted **, and the existing vision does not need to be prematurely fitted with glasses. The key is to use the right method, and it is a prerequisite to effectively improve the autoregulatory function of the eye muscles.

Not necessarily, the best corrected visual acuity for the general age of 6 years old is that is, it also depends on the results of experiential light, which can be myopia, farsightedness, and astigmatism. It may also be temporary eye fatigue, so it is recommended to go for a detailed examination to determine the conclusion.

Myopia is an irreversible change, and there is currently no safe and effective way to restore it.

The eye is like a finely tuned instrument. Under normal circumstances, light rays are refracted through the cornea, lens, vitreous humor, and other parts in turn, and finally form an image on the retina.

When the human eye is in a relaxed state of adjustment, parallel light rays are focused in front of the retina after passing through the refractive system of the eyeball, which is called myopia.

Medically, myopia is divided into refractive myopia and axial myopia, the former is related to changes in the refractive power of the cornea or lens, and the latter is caused by the prolongation of the axial length, which is what we often call true myopia and "pseudomyopia".

However, "pseudomyopia" is only caused by ciliary muscle spasm, not refractive myopia. Also known as "accommodative myopia".

Accommodative myopia is "reversible and preventable**. However, if "accommodative myopia" is not detected and solved in time, it will also evolve into true myopia. True myopia, on the other hand, is irreversible.

The basic principles of myopia are to change the refraction path of light or delay the growth of the eye axis, and control the progression of myopia, but it is impossible to reverse the structural changes that have occurred in myopia.

Therefore, the only thing that can be done after myopia is to delay the rate of myopia progression.
