Depending on the situation, refractive errors include farsightedness, myopia, and astigmatism. There are many refractive errors, among which genetic factors are very important. Myopic eyes**, mild and moderate myopia can be corrected with a moderately concave lens.
Hyperopia**, hyperopia, does not require treatment if vision is normal and unconscious. If there are signs of visual exhaustion or visual impairment, it should be corrected with an appropriate convex lens.

Hello, first of all, you need to figure out whether it is true myopia or pseudomyopia, if pseudomyopia is caused by excessive tension of the ciliary muscle, after training, cycloplegia, acupuncture and other methods can be recovered, and true myopia is irreversible, once true myopia is formed, unless through surgery, there is no other way to completely remove the glasses.

If you can't see clearly, then 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, dusk, moonlit with weak light, strong sunlight, 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 acupuncture acupuncture points of Chinese medicine, combined with jujube kuan return to the medical clinic and recreation sports, 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.
The reason for regular check-ups is that the structure of the eyeball, binocular visual function, and intelligence of children with cleft pins are still in the process of continuous development after birth, and the contents of the examination are 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.

Refractive error, which is the presence of nearsightedness, farsightedness or astigmatism.
There are many reasons for refractive error, among which genetic factors are very important reasons, of course, unreasonable eye use is also a reason that cannot be ignored, children are in the period of growth and development, and do not pay attention to eye hygiene, such as reading, writing posture is incorrect, or the light is not good, resulting in the distance between the eyes and the book is too close, or reading for too long, or walking, sitting in the car to read a book, etc., can cause excessive eye fatigue, resulting in refractive error.
The following principles should be followed for refractive errors:
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 supplementation of vision nutrients to enhance the anti-fatigue ability of the eyes and improve refractive error.
This is the most important and fundamental thing. It is recommended to take Joy Vision Nutrients, take it with warm water, and insist on taking it for a period of time, the child's refractive error will gradually be corrected, and the younger the age, the easier it is to recover.

It can be surgically surgical**. However, specific examinations are required. Refractive surgery must be at least 18 years old, and secondly, the prescription must be stable, and there must be no active eye disease in the eye.
As for whether it can be done, it is necessary to perform a lot of general ophthalmological examinations, corneal topography, intraocular pressure, corneal thickness, fundus examination, and ocular AB ultrasound measurements, which need to be completed by the ophthalmology clinic. Before the examination, stop wearing contact lenses, and it will take 3 to more than 2 weeks for soft and at least 3 weeks for hard ones.
-
If you can**, you don't need glasses first, and after a period of time, see how the effect is to decide whether to refraction glasses**.

Refractive error is a common type of eye refractive defect that usually has three types: myopia, farsightedness, and astigmatism. It is best for you to go to the hospital to do a careful examination to see what the cause is. Not all of them can't**.
-
Of course you can. I am a myopic patient myself, and I also have refractive errors. After taking two pills a day, my myopia is now well controlled.

**Refractive error methods include myopia: moderate negative lenses, i.e., concave lenses, should be worn to correct vision; Farsightedness: Moderate positive lenses, i.e., convex lenses, should be worn to correct vision; If it's astigmatism:
Astigmatism includes mixed astigmatism, myopic astigmatism, farsighted astigmatism and repetitive astigmatism, and corresponding astigmatism lenses should be worn to correct vision according to the nature of astigmatism; Amblyopia: If amblyopia is present, amblyopia should also be performed**. Vision can be corrected with appropriate glasses and, if necessary, surgery**.
Myopia laser surgery is often referred to as "excimer laser surgery", which uses an excimer laser to reduce the corneal curvature in the pupil area by refractive cutting of the stromal layer under the corneal flap, so as to achieve the purpose of correcting myopia.

Yes, correction, or **.

Wear glasses for correction or surgery.

Refractive error refers to the inability of the eye to form a clear image on the retina after parallel light rays pass through the refractive action of the eye without the use of accommodation, but imaging in front of or behind the retina. It includes farsightedness, myopia, and astigmatism. The specific hazards are reflected in the following aspects:
Mild or moderate myopia, except for blurred vision, there are no other symptoms, when working at close range, no need to adjust or use less adjustment to see the small target, but feel convenient, but in the highly myopic eye, the target distance is very close when working, and the eyes are too inwardly gathered, which will cause excessive use of the medial rectus muscle and the symptoms of visual fatigue.
The visual acuity of the farsighted hyperopia eye is determined by the level of its farsightedness refraction and the strength of the adjustment power, mild hyperopia, which can be overcome with a small part of the adjustment force, the distance and near vision can be normal, generally asymptomatic, such hyperopia is called recessive hyperopia, slightly heavier hyperopia or the adjustment force is slightly insufficient, so the distance and near vision are not good, these can not be completely compensated by the adjustment of the remaining part is called overt hyperopia, the sum of recessive hyperopia and vision is called total hyperopia, and the hyperopia eye is in a state of adjustment tension for a long time, Symptoms of eye fatigue can easily occur.
Patients with low astigmatism refractive power may be asymptomatic, and slightly higher astigmatism may have vision loss, and vision is not clear near and far, as if there is double vision, and there are often symptoms of visual fatigue.
Eye fatigue. Refers to reading, writing or doing close work for a long time, there can be blurred handwriting or goals, dry eyes, heavy eyelids, fatigue, and eye pain and headache, after a short rest, the symptoms are significantly reduced or disappeared, this symptom is generally in the afternoon and evening is the most common, severe even nausea, vomiting, sometimes complicated by chronic conjunctivitis, blepharitis or stye reversal.

Refractive impropriety is not serious Answer: Hello Tang Bin, it is recommended to take the child to the eye hospital for dilated eye refraction to find out the true myopia. If it is true myopia, it is recommended to wear glasses to correct the refraction and achieve the effect of clear vision.
Wait until you are 18 years old before considering surgery**. If pseudomyopia is present, glasses are not required.
Refractive error is not very serious Answerer: Wu Jian refractive error, ophthalmic disease refractive error The term refractive error is not very familiar to most people, but people are not unfamiliar with myopia, farsightedness and astigmatism. Refractive error refers to abnormal refractive states such as myopia, farsightedness, astigmatism, and anisometropia.
Refractive error can generally be corrected with glasses, the appearance of the glasses people wear are similar, but myopia, farsightedness, astigmatism wear glasses are not the same, they need to be: myopia with a concave lens correction, hyperopia eyes need to wear a convex lens, astigmatism needs to be corrected by a cylindrical lens
Myopia, farsightedness, and astigmatism are all examples of refractive errors, which can cause blurred vision.

The refractive state of the eye is divided into two main categories. One type is called emmetropia; One is called non-emmetropic eyes, and the latter is also known as refractive error. Refractive errors are divided into three categories:
The focus is on the back of the retina and becomes hyperopia; Those who focus on the front of the retina become myopia; If the refractive power of each meridian of the eye is different and cannot form a focal point, it is called astigmatism. It is best to do further examination, and then see if it is very serious, if it is more serious, it is better to ** early, and it is not difficult to treat it for a long time.
-
Refractive error is mainly divided into myopic refractive error, farsighted refractive error and astigmatism, myopic refractive error is divided into mild myopia, moderate myopia, high myopia, mild myopia is mostly within 300 degrees, moderate myopia is 300-600 degrees, high myopia is greater than 600 degrees, hyperopia is divided into low, moderate and high, low is +300 degrees, moderate is +300-+500 degrees, and height is greater than +500 degrees.
Astigmatism is divided into regular astigmatism and irregular astigmatism, in which astigmatism generally does not appear alone, more or less accompanied by myopia or farsightedness, so when the patient finds refractive error, it is necessary to carry out refraction in time, refractive error is not serious or serious, this depends on the patient's experience of light, at present**, under the age of 18 to give glasses**, after the age of 18, according to the patient's own wishes to continue glasses or myopia laser correction.

The success story is shown below
If you want to know how to restore your vision, you need to understand the principle of myopia.
Taking adolescent myopia as an example, most of the juvenile myopia is caused by the thickening of the lens and the spasm of the ciliary muscle, as shown in the figure below, the lens is a convex lens, which has the effect of converging light, the convex lens becomes thicker, and the ability to gather light becomes stronger. (as shown below).
Eyeglasses, which do not change the internal function of the eyeball, add a concave lens that diverges light on the outside to counteract the convergence effect caused by the thickening of the lens, the child's eye is developing until the age of 18, so the prescription of the glasses will increase with age.
Traditional Chinese medicine believes that "the eyes are the gathering of the lineage, and the qi of the five internal organs and six internal organs are all focused on the essence of the eyes"; The reason why the eyes can see everything and distinguish colors depends on the nourishment of the body's essence and energy, so that they can maintain their normal function.
The Yellow Emperor's Neijing said: The general rule is clear, and if it is not passed, it is an obstacle. If the meridians are blocked, the essence cannot be greater than the eyes, and the eyes will have various visible and invisible pathological reactions.
Traditional Chinese medicine massage is used to dredge the meridians through massage, improve blood circulation and nutrient supply to the eyes, enhance and restore the ability of the lens and ciliary muscles to regulate themselves, and fundamentally improve and restore vision. It has a good effect on adolescent pseudomyopia, true myopia, amblyopia, and astigmatism. (pictured above).

Refractive error is first checked for false or true refractive error, and dilated refraction is required. If the refractive error is false, you can massage the dilated pupil and rest and recover, if the refractive error is true, it can only be treated with glasses or laser surgery.
