I am 12 years old and have a visual acuity of 4 6 degrees whether it is pseudomyopia or true myopia

Pseudomyopia is relative to true myopia. True myopia is when the refractive system of the emmematic eye is at rest, that is, the far point of the eye is within a limited distance after the adjustment is removed. In other words, myopia is caused by congenital or acquired factors that cause the anterior and posterior diameter of the eye to become longer, and parallel rays of light enter the eye and form a focal point in front of the retina, causing blurred vision.

In pseudomyopia, there is a partial accommodative effect when looking at distant objects (see Figure 15).

It is common in adolescent students when looking at close objects, due to the degree of use of adjustment is too strong and the duration is too long, resulting in continuous contraction of the ciliary muscle, causing adjustment tension or withering spasm, so when turning to distant after a long time of reading and writing, it can not quickly relax the adjustment, resulting in dizziness, eye swelling, vision loss and other visual fatigue symptoms. This condition of myopia due to the increased refractive power of the eye makes the eye myopia, which is called pseudomyopia. Both pseudomyopia and true myopia have the characteristics of visual fatigue and poor distance vision and good near vision in terms of symptoms.

However, pseudomyopia is a functional change, and there is no problem of the anterior and posterior diameter of the eyeball, but only to adjust spasticity, and most of them can be turned into farsightedness or emmetropia after being spotted with cycloplegic drugs. If you wear myopia lenses according to true myopia**, the eyes will feel very uncomfortable because they do not relieve the adjustment spasm, and there is even a risk of myopia development. Therefore, pseudomyopia is different from true myopia.

At present, there are many methods of pseudomyopia, mainly to relax and adjust to achieve the purpose of treating fake and preventing real. Commonly used methods are: (1) relaxation and regulation; Dilated pupils**:

The cycloplegic agent is used to dilate the pupils, and the eye drops are currently applied once a day. Convex lens method: first ask the patient to wear a convex lens with a higher number, look at the eye chart 5 meters away to relax the ciliary muscle, and then adjust the power of the convex lens to make the vision basically normal.

Distant view method: After studying or writing for 1 or 2 hours, you can look at the natural scenery in the distance to relax the ciliary muscles. Insist on doing eye exercises 3 to 4 times a day.

2) Methods to improve the excitability of the visual center and improve visual function: direct current**myopia, auricular acupuncture, plum blossom needle, acupoint massage, acupoint conduction, qigong** and cold water bath**, etc. It mainly increases the excitability of the optic center and optic nerve cells of the brain, which can improve both near and far vision.

3) Improve the learning environment: pay attention to maintaining a distance of 30 cm and correct posture when reading and writing. Pay attention to natural light and ensure adequate lighting in the room.

Combine work and rest, get rid of bad study habits, take a break for 10 15 minutes every 1 hour of reading, and don't lie down or walk to read. Pay attention to physical activity.

Because pseudomyopia is aggravated with the extension of near time and the increase of accommodation, and decreases or disappears with the degree of distance and adjustment relaxation, pseudomyopia has the characteristics of cure, incurable and incurable. A variety of approaches** may have some effect, but none of them will last. Therefore, it is important to educate adolescents and children to develop the habit of protecting their eyesight from an early age and avoid excessive adjustment of the ciliary muscle and continuous tension, which is the key to preventing the occurrence of myopia.

2 Pseudomyopia will become true myopia if it is not relieved in time.

This needs to be done at the hospital's ophthalmology department to be confirmed.

It cannot be judged by age.

The child, after going to the ophthalmology department of the hospital to dilate the pupils, can it be determined that it is true or false myopia.

The common unit of visual conversion is about 250 degrees, which is considered moderate myopia. Although moderate and severe myopia is not like severe myopia, you can't do anything without glasses, but when you look at things, you still don't feel more or less clearly. Some parents wonder if their child's vision is pseudomyopia.

So, is vision pseudomyopia?

1. In the hospital examination, if the visual acuity is greater than that, it is hand pseudomyopia; Otherwise, it's true myopia.

2. Under normal circumstances, when 5 years old (or older), the naked eye vision should be reached, otherwise it may be myopia; If the corrected visual acuity is low, it may be amblyopia, and a detailed examination is required after dilated refraction.

3. Pseudomyopia can be recovered by rest and eye hygiene, while true myopia cannot.

4. Simple moderate and low myopia can completely or partially restore vision if the right approach is taken.

Some parents think that their children can't wear glasses when they're nearsighted, otherwise they will become more serious. This is a wrong view. If they don't wear glasses, their children will see closer.

In this way, their myopia will become more and more severe. There are also many children who are used to squinting after myopia, which is not good. After knowing what to do with your child's vision, they also need to take your child to a specialized hospital to buy glasses.

Fake it, pay attention to eye hygiene, go outdoors for more exercise, and remember every fist, foot, inch or something, it will be better.

It should be fake, watch less TV, computer, look at it for a while after 45 minutes, and abide by it!!

Pseudomyopia is caused by the continuous contraction and spasm of the ciliary muscle, the thickness of the lens increases, and the vision is blurred. Medications, acupuncture, ear acupuncture and physiotherapy equipment, or through the patient's own eye muscle strengthening exercises can relax the muscles, relieve fatigue, and restore vision to a normal state. If pseudomyopia is not relieved in time, it will eventually lead to the enlargement of the eye axis and become true myopia.

At present, there is no clear record of how many degrees of pseudomyopia can reach, some people may be 200 degrees, and some people may be 300 degrees or pseudomyopia, which can only be determined after the hospital dilated eye refraction.

However, pseudomyopia can be recovered quickly if it is timely**. Commonly used methods are:

1. Correct bad eye habits in a timely manner.

Once you find that your vision is declining, you must find out the main cause and correct your bad eye habits in time. Only by correcting bad habits in time can you stop the channel of continued vision loss. So, this is one of the very important factors.

Second, it is necessary to reasonably arrange the combination of work and rest, work and rest.

On the basis of correcting bad eye habits, we must reasonably arrange work and rest, and achieve a combination of work and rest. It is necessary to arrange work and rest reasonably, so as to combine work and rest to ensure sufficient sleep time, and at the same time, it also prevents long-term eye use, which can prevent vision from continuing to deteriorate.

3. Participate in sports appropriately.

Proper participation in sports can increase the rate of blood circulation around the eyeball, which can improve the flexibility of the eye muscles. Especially when playing sports such as ball games, the line of sight will follow the movement of objects at different distances, which can prevent further deterioration of vision.

Fourth, pay attention to the diet and have a balanced nutrition.

Although the daily diet is mainly based on cereals, it is necessary to supplement vegetables and fruits, so as to achieve a reasonable distribution of protein, sugar and fat. Eat less sweets and more purple foods.

5. Timely supplement of vision nutrients to enhance the anti-fatigue ability of the eyes and restore vision.

This is the most important and fundamental thing. It is recommended to take Leyan Vision Nutrients, take it with warm water, and insist on taking it for a period of time, the child's myopia will gradually decrease, and pseudomyopia will gradually recover.

Pseudomyopia has no degree, and the so-called pseudomyopia is due to the frequent incorrect use of the eye, the ciliary muscle continues to contract and spasm, and the lens is also in a state of thickening. In this way, the parallel light from the outside enters the eye, and after the atrial refraction of the thickened lens, the focus falls in front of the retina, and it is naturally not clear to see things in the distance. During this period, there are no organic changes in the eyeball, and if you can take proper rest and **, pay attention to eye hygiene, and use the eyes reasonably, there is hope to restore normal vision.

However, if it is not corrected in time in the stage of pseudomyopia, it will develop into true myopia over time. **There are many methods of pseudomyopia, mainly relaxation and regulation, such as: the use of cycloplegic agents to dilate pupils, acupuncture, physiotherapy, improve the learning environment, pay attention to eye hygiene, and do eye exercises seriously.

If the child's prescription is less than 100 degrees, the child may be considered pseudomyopia.

There is not a difference in the degree of myopia, but a difference in the cause of myopia and true myopia. True myopia is an eye disease caused by a change in the structure of the eyeball, and the eyeball grows too long and too fast, causing the focal length to fall in front of the retina.

Although pseudomyopia is also manifested as myopia, and the focal length of light falls in front of the retina, the cause of its formation is not the structural change of the eyeball, but the change of the lens refractive power caused by the spasm of the ciliary muscle in the eye due to long-term fatigue contraction. Therefore, pseudomyopia can be completely recovered by **, while true myopia is a structural change.

Generally, if the visual acuity is reduced within 2 months and the power is below 75 degrees, pseudomyopia is suspected. However, if there is no degree after mydriasis, it is pseudomyopia, and if there is still a degree, it is true myopia.

Condition analysis: Hello, above 300 degrees belongs to true myopia, must be corrected with glasses and surgery, below 200 degrees can pay attention to eye hygiene, avoid visual fatigue can be recovered. Suggestions:

True or false myopia has little to do with the degree, mainly to see if there is a prescription after the dilated pupils.

If there is no myopia after mydriasis, it means pseudomyopia, and if the mydriasis persists, it means true myopia.

Our team of experts will tell you:

How to distinguish true and false myopia?

To identify true and false myopia, in addition to the optometry version of the hospital, the simple method can be 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 the eyes, 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.

The child has 300 degrees of myopia, and it must be true myopia. Stepping up the correction of glasses is the key.

The so-called pseudo-myopia is manifested as a myopic state under the attack of normalcy, and after the adjustment and relaxation (paralysis), the myopia state disappears, showing emmetropia or hyperopia, so the most effective and accurate method to distinguish between true and false myopia is to do standardized "cycloplegic" refraction, which is commonly known as dilated refraction. Pseudomyopia is actually not myopia.

Hello, it is impossible to judge whether it is true or false from the prescription, which can only be judged after the hospital does a dilated eye refraction. In general, if it is false, the vision will gradually recover after the pupils are dilated.

First of all, the result of measuring visual acuity is not how many degrees of myopia there is. Thirdly, there is no degree of pseudomyopia, and the so-called pseudomyopia can be ruled out by dilating the pupils, and the light detected is the true power.

Hello, pseudomyopia is the degree that can disappear after dilating the pupil examination, while true myopia is irreversible. If it is a student who has just become myopia, you need to check whether this degree is true myopia or pseudomyopia through dilated eye refraction, and if it is pseudomyopia, you need to pay attention to the usual eye time, light, posture, distance, balanced diet, and insist on doing eye exercises every day. If you have true myopia, it is recommended to go to the hospital for a check-up, and the doctor will introduce you to the most suitable solution.

1. True myopia: after cycloplegia, the degree of myopia disappears, or the degree of reduction is less.

2. Mixed myopia: After cycloplegia, the refractive power of myopia decreases significantly, but it does not return to emmetropia.

It seems that about 300 degrees is pseudomyopia.

Generally, below 300 degrees is pseudomyopia, myopia is caused by a long-term lack of lutein in the macular area of the retina.

Visual acuity alone cannot diagnose true myopia and pseudomyopia. If you need to go to a professional eye hospital for examination and diagnosis, if you find that you have vision problems, go to the hospital for examination as soon as possible**Oh,
