Questions about astigmatism on your child s refractive exam?

The data on this list is exaggerated because the person who set the parameters of the instrument is not an expert, and the "final prescription" of the data on this list should be the data in the figure below. The following 3 "? "These are all incorrect judgments.

It should be said that the current problems of children are: hyperopia accommodative reserve is too low; Severe astigmatism (easy to induce amblyopia and strabismus).

The child's physiological farsightedness is shown in the table below:

You can take your child to a professional eye hospital for a medical optometry examination, which is more accurate and can accurately understand the child's specific vision. Astigmatism is a kind of refractive error, which has a greater impact on children's vision, which can easily cause eye fatigue and even cause a series of problems.

1. Children with astigmatism need to adjust their vision in order to see the scenery clearly, which is used to improve the clarity of the object, if you are highly astigmatism, if not corrected in time, it is easy to cause headaches, visual fatigue, etc.

2. Vision loss: astigmatism will make the retina unable to see the shape of the object clearly, and the things seen are ghosted, which is not easy to identify, and the brain needs to get an accurate object, which will strengthen the adjustment of the eyes.

3. Cause amblyopia: such a situation appears in people with high astigmatism, and farsightedness astigmatism should also be paid special attention to, because whether it is near or far away, it is not clear to see, the visual system is not exercised, and the visual cells will be in a state of "atrophy", and over time amblyopia will form amblyopia, and amblyopia and strabismus complement each other, and it is easy to form strabismus with amblyopia.

Astigmatism is also divided into regular astigmatism and irregular astigmatism, if the child has regular astigmatism, it has no effect on vision and does not need to be corrected. However, pay attention to the usual use of your eyes. However, if the child's astigmatism often causes visual fatigue, even if the astigmatism is very low, it needs to be corrected.

1. For children with excessive farsightedness, the ratio of the anterior and posterior diameter of the eyeball and the upper and lower diameters is less than 1, that is, there is a difference in the radius of each meridian, so astigmatism exists objectively;

2. For children with high hyperopia, the presence of astigmatism is beneficial to emmetropia, that is, to reduce the degree of hyperopia;

3. From the perspective of biogenetics and optics, the information to the brain caused by this dispersion of optical conduction reaction is: the eyes should grow rounder, which will promote the growth of the anterior and posterior diameters of the eyeball (the focus and focus line formed by hyperopia + hyperopia astigmatism are behind the retina, and the development of the eyeball, just like the sunflower, follows the sun - the eyeball develops in the direction of focus).

When I did the physical examination for entering the kindergarten, I said that the child had astigmatism.

Nowadays, many preschool and school-age children will receive vision screening, and these things are in the screening, many children are found to have refractive error, so these children need to have a refractive examination, so what is a refractive examination? Why should my child have a refractive test? Let's take a look at these questions together.

More than 80% of our human information needs to be obtained through our vision, if the child has refractive error, it will seriously affect the child's learning and life. Refractive error refers to the fact that when the human eye does not use adjustment, the parallel light will pass through the refractive action of the eye, and cannot form some clear images on the retina of the eye, but in the front or back of the retina, such as myopia, farsightedness and astigmatism, etc. are refractive errors, but there are many reasons for refractive error, among which genetic factors are particularly important. In addition, children with unreasonable eye use will also lead to refractive error, so children should have a refractive examination, which can effectively intervene and detect early.

Prevention of refractive error usually needs to be corrected in the child's daily life, for example, when reading and writing, the posture should be correct, do not lie on the table or tilt your head to learn, and you can not lie down to read, usually when reading or writing, the distance between the book and the eye is best kept at about 30 cm, and do not study in a place with sunlight and sufficient light, in addition to preventing eye fatigue to study for too long, one time to control about 40 minutes, Then rest for 10 minutes, you can look at distant objects, and you can usually eat more whole grains and less sugar to prevent refractive error.

All in all, it is necessary to have a laser test done in advance for a noisy child, and the child can also prevent refractive error by maintaining some good habits in daily life.

It is recommended to go to the hospital for accurate optometry to determine the type of refractive error in the eye.

Also note:

1. The time of close eye use should not be too long, every 40-50 minutes, you should take a little rest for 3-5 minutes, and look into the distance to relieve visual fatigue.

2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.

3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia. In addition, it is also necessary to pay attention to regular supplementation of eye vision nutrients, not from the nutrients needed by the eyes, enhance the anti-fatigue ability of the eyes, and better protect the eyesight.

Fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to obstruct the vision of the hand shadow. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.

Generally, desktop lamps should be less than 40 watts.

5. Avoid reading while walking or reading in a walking car. Because the carriage is vibrating and the body is shaking, Huai Yinzao's eyes and books cannot be fixed, and the burden on the glasses will increase. Often, this is likely to lead to myopia.

6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.

Malnourished and weak children are prone to myopia.

7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.

8. Eat less candy and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

Children's refractive examination is to check children's eyesight, children's eyesight has a problem, must go to some regular hospitals as soon as possible, use refractive examination to detect Nianwu, but also need to cooperate with other examinations to be able to check out the specific vision.

Because the child has some blurred vision, the refractive examination room checks the child's vision and determines the prescription of the glasses by understanding the refractive degree of the eyeball.

In order to ensure the child's health, the socks can make the child have more changes, and it will help the growth of the bridge child.

It is a professional term that refers to the need to check the child's eyesight, and to go to a professional hospital, so that the child's vision can be checked in a timely manner, and the degree can be corrected.

After checking the eyesight, you can avoid risks, prevent the key to prevent it from happening, and make your vision better.

The main thing is to check the child's eyesight. This can diagnose some problems and prevent problems with the child's vision, which is good for the child.

Check myopia, the proportion of myopia in China is relatively high, and we must start with children for eye prevention. Through the refractive file, pay attention to the child's eye development changes in time, only when it is found can his vision control degree be improved as much as possible, and when the child grows up, the vision can also be guaranteed to remain at a relatively healthy level. High myopia is our top priority for prevention and control.

If there are people with high myopia or cases above 600 or 800 degrees in the family, we need to be vigilant, do a good job of children's healthy development files earlier, and pay more attention to myopia prevention and treatment.

How to prevent myopia in daily life? The prevention and treatment of myopia is mainly reflected in three aspects. Increase outdoor activities, don't stay indoors, go outdoors, even if it's not sports, outdoor activities can be in natural light, outdoor activities have a certain prevention and treatment effect on preventing and slowing down myopia, under the professional guidance of doctors, combined with some optical means, including lens means, OK lens means, scientific and standardized lenses, so that children can get clear vision in time when the power changes.

It is recommended to regulate ophthalmology and hospitals.

If I take my child for an eye test, what tests do I need? Standard refraction, anterior eyelid and fundus examination must be done. It is the refraction pupil, which can be restored within 6-8 hours, which can make the refraction more accurate.

The length of the eyeball should be measured, because the change of myopia, especially high myopia, is overwhelmingly due to the fact that the eyeball is too long. Look at your child's height and weight to know if your child's foundation is healthy, and you should also look at the length of your eyes to monitor your vision health. In patients with myopia in the family, fundus examination is crucial.

How long does it take to recover after expansion? Zhou Xingtao: The dilated refraction time is very short, up to 6 hours to 8 hours, the pupils will return to their natural state, and taking the child for examination on weekends or evenings will not affect the child's learning.

Dilatation refraction is not terrible, and children do not need to wait until the peak of winter and summer.

If the computer refraction is not accurate, the correct prescription should be obtained by dilated refraction; 3.When the astigmatism is high, the child often adopts a special eye position to reduce the impact of astigmatism on astigmatism; 4.Three-year-olds with astigmatism of more than 150 degrees may cause amblyopia.

The corrected visual acuity of the child should be above, if the visual acuity is lower than that at the time of revision, amblyopia should be considered, and it needs to be timely**; 6.Visual acuity measurement is important to determine whether amblyopia is present, and children must be taught to look at the eye chart before dilated eye refraction.

It means that myopia plus astigmatism, astigmatism is quite deep, and this problem should be paid attention to, but your data is typed out by the computer, which is not necessarily accurate.

If astigmatism is really so high, only wear glasses, don't talk about it, astigmatism can't be ***. Just wear glasses.

Want to roll your eyes and watch the computer and TV, right? "Of course it's not good, this phenomenon can be one of the symptoms that the child does have problems with his eyesight.

It is recommended that you must go for a review after the year, and you must not be sloppy, remember, otherwise it will develop into amblyopia.

Hello :r: 166

The myopia degree of the right eye is 75 degrees, myopia astigmatism is 475 degrees, and the axis position is 166 "It belongs to irregular astigmatism".

5. The myopia degree of the left eye is 125 degrees, the myopia astigmatism is 325 degrees, and the axis position is 5 "belonging to irregular astigmatism".

Astigmatism is generally high astigmatism when the degree of astigmatism reaches more than 200 degrees, and astigmatism is also a medical problem in the world, and there is no completely effective method. It is recommended to follow the doctor's advice in a timely manner**, what you call pupil dilation refraction is also called medical refraction, simply put, you make the ciliary muscle in a relaxed state by dotting ciliary muscle paralysis agent, so that the parameters of refraction are more accurate.

As for the formation of astigmatism, there are internal and external causes. The vast majority of astigmatism is congenital, acquired as a result of poor eye hygiene or corneal trauma.

If the above data is computerized optometry, and the real optometry data may be very different, it is better to follow the doctor's advice to do pupil dilation first before making the next step!

If you have any questions, you can continue to ask!

Hello : The baby is only 3 years old, be sure to control the contact with the computer! Also, the baby's vision must be checked in a regular eye hospital, from a medical point of view, the baby's current age can not be refracted with a computer refractor!

This has a certain impact on babies and young children! If it is ruled out that the baby is caused by contact with the computer, it is likely to be amblyopia astigmatism, which must be corrected in time! Infantile amblyopia strabismus must be corrected before the age of 8, with good results (normal is 4-6 years old), more than 8 years old, there is almost no effect!

You must be in a hurry! You can learn from the experience by going to a few larger eye hospitals for check-ups! Don't trust what instruments, drugs, etc.!

It's not a question of wasting money! Instead, it will delay the baby's best age correction time! Feel free to continue asking questions, thank you!

I also hope that the baby's vision condition can recover as soon as possible! I wish you a healthy and happy baby and a happy new year!
