How can I tell if I have true myopia or pseudomyopia?

From different perspectives, there will be a variety of classifications.

1.According to the clinical pathology, it can be divided into simple myopia and progressive myopia.

Simple myopia: that is, general myopia, low to moderate myopia with a refractive power of less than 600 degrees, and the progressive development of myopia is slow. The tissues of the eyeball are normal, and no pathological changes appear.

Progressive myopia: the so-called high myopia, also known as pathological myopia, has a refractive power of more than 600 degrees and can reach up to 4000 degrees. Generally, the onset is early, the axial diameter of the eyeball continues to lengthen, and a series of pathological changes can occur in many tissues of the eyeball.

2.According to the degree of myopia, it can be divided into low, moderate and high myopia.

Low-grade myopia: those with a diopter of less than or equal to 300 degrees.

Moderate myopia: myopia with a diopter between 300 and 600 degrees.

High myopia: those with a diopter higher than 600 degrees.

3.According to the influence of eye accommodation, it can be divided into pseudomyopia, true myopia and mixed myopia.

This type of myopia generally falls into the category of simple myopia.

Pseudomyopia: also known as accommodative myopia, in which the axial length of the eye is normal, but the refractive force of the refractive interstitium exceeds the constant, and the lens is generally overaccommodated, so the distant light enters the eye and is imaged in front of the retina. The refraction of myopia disappears completely after pupil dilation, and it is manifested as emmetropia or hyperopia.

True myopia: also known as axial myopia, the refractive interstitium of the refractive interstitium is normal, the anteroposterior diameter of the eye axis is extended, and distant light rays are imaged in front of the retina after entering the eye.

Mixed myopia: a condition in which true and false myopia coexist. Myopia has a greater decrease in refraction after mydriasis, but it is still myopia. Adolescent myopia students are mostly in this state of myopia in the process of heavy learning tasks and physical development.

The myopia targeted by this product refers to true and false myopia and mixed myopia in simple myopia.

Regular optical stores can check small hole optometry.

It can be checked after the hospital dilates the pupils.

The main reason for judging for yourself is that there is no good standard, but if you use your eyes too much, then take a good rest and see if it improves.

It is necessary to go to a professional institution to dilate the pupils with eye drops.

Drop every 5 minutes.

5 Half an hour after 8 refractions.

You can find out whether it is true myopia or pseudomyopia.

Below 100 degrees is fake.

More than 100 can also be astigmatism, if not astigmatism, it is true.

It's best to go to the hospital to check it out.

How to distinguish between myopia and astigmatism, how to distinguish it?

1. The difference between true and false myopia.

1. Whether the vision can be restored naturally. We know that true myopia is an organic change, and the eyeball of a myopic patient has become a myopic eye, and it is impossible to recover vision naturally. Pseudomyopia is due to the fact that the human eyeball has not become longer, at this time, as long as you can take proper rest and **, pay attention to eye hygiene, and develop good eye habits, you can restore normal vision.

This is also the main difference between pseudomyopia and true myopia.

2. If the pseudomyopia stage is not corrected in time, it will develop into true myopia after a long time.

3. The symptoms are different. The main symptoms of pseudomyopia are: squinting, frequent blinking, eye rubbing, tilting of the head, frowning, wrenching, squinting, watching TV often leaning forward, looking far and blurred, often making mistakes, lack of concentration, and frequent headaches.

True myopia refers to double vision, eye swelling and pain, headache, nausea, exotropia, and in severe cases, fundus changes, proptosis, and other symptoms.

2. How to distinguish true myopia from pseudomyopia?

If pseudomyopia is suspected, you can go to the hospital for an eye examination. If there is no change in myopia, farsightedness and astigmatism refraction, the visual acuity has also improved significantly or returned to normal, indicating the existence of pseudomyopia. Because if it is true myopia, the patient's eye axis has become longer, then there must be corresponding myopic refractive changes after dilating the pupils and paralyzing the ciliary muscle, and the vision will not improve after the dilation.

It is a kind of myopia that has no degree after dilation, which is pseudomyopia, which can be reversed.

After dilation, myopia with a degree is true myopia and is irreversible.

However, most of these two need to be corrected, but most of the true myopia requires glasses, and you also 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, so that the eyes can be full of 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 acupuncture acupuncture points of Chinese medicine, combined with sports, and 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 level are still in the process of continuous development after birth, and the contents of the examination can be 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.

1) Pseudomyopia: Distance vision is reduced, but after the use of cycloplegic agents (such as atropine ophthalmic drugs) or the use of foggy vision**, myopia disappears, and it becomes emmetropia or farsightedness. This myopia phenomenon is caused by the tension of accommodation, so the myopia disappears when the adjustment is relaxed.

It usually occurs in people who are young, have a short onset of disease, and have a low degree of myopia.

2) True myopia: refers to the usual state of myopia, after the use of cycloplegic agents or foggy vision**, the degree of myopia has not decreased, or the reduced power is lower than the refraction. This type of myopia is mainly caused by the elongation of the eye axis, and there is no obvious relationship with accommodation.

It usually occurs in older people, with a longer onset of disease and a higher degree of myopia.

True myopia and pseudomyopia are two different types of myopia symptoms that can be distinguished in the following ways:

Eyeball length: True myopia is caused by the longer length of the eyeball, where the light rays focused by the eye are concentrated in front of the retina, causing distant objects to blur. Pseudomyopia is caused by problems with the adjustment of the muscles of the eye, usually caused by overuse of myopic vision.

Age factor: True myopia usually begins in childhood or adolescence and progressively worsens. Pseudomyopia can occur at any age, but it is more common when working in close proximity for long periods of time and overusing the eyes.

Changes in vision: Visual acuity in true myopia is usually significantly improved with the help of myopia lenses, which are able to focus light on the retina correctly. Whereas, vision in pseudomyopia can be restored after a period of rest, such as resting with your eyes closed or working away from close proximity.

Eye exams: Regular eye exams are an effective way to determine the type of myopia. An ophthalmologist will help determine the type of myopia by measuring indicators such as intraocular pressure, corneal curvature, and refraction to assess eye structure and refraction abnormalities.

If you suspect that you or someone else has myopia, please consult a professional ophthalmologist for a diagnosis and further guidance. Only a professional family assessment can accurately distinguish and determine the type of myopia.

At present, there are many professional institutions in China that focus on the prevention and control of myopia in adolescents. Help parents and children to prevent and improve in the best possible time. For example, Mengying Ophthalmology is an incubation brand of Shanghai Owl Biotechnology, the company has developed a multi-dimensional myopia prevention and control program integrating medical Qingsui slip prevention and control, eye care habits, outdoor sports, etc., which is equipped with digital information technology such as smart diagnosis and treatment, smart marketing, smart college, AI**, AI prevention and control, etc., to create its brand "Mengying" intelligent ophthalmology.

Pseudomyopia is one of the most common eye diseases among adolescent students. This is due to the excessive adjustment of the adolescent eye, on the basis of not paying attention to eye hygiene, excessive use of adjustment, resulting in continuous contraction of the ciliary muscle, so that the refractive power of the eye is enhanced and myopia is formed, such myopia is called pseudomyopia. Whether it is true myopia or pseudomyopia, their distance vision is reduced, near vision is normal, and distance vision is improved after wearing myopia glasses, but pseudomyopia is a functional change, as long as you try to relax the ciliary muscle, you don't need to wear glasses.

True myopia is an organic change that can only be corrected by wearing glasses. However, there is a close relationship between the two, and if pseudomyopia is not corrected in time**, it can further develop into true myopia. Therefore, it is necessary to correctly distinguish the two kinds of myopia, first of all, you can use dilated pupils to measure visual acuity, point to dilate the pupils with dilated drugs to fully dilate the pupils, add a small hole scope to check the naked eye vision, if the vision does not change after the dilation of the pupils, it is true myopia, and the increase in vision is pseudomyopia, in addition, it can be tested by dilated eye refraction, and the image is detected after dilation, if the light and shadow are smooth for pseudomyopia, if the light and shadow are reversed, it is true myopia, and the cloud and fog method can also be used to let both eyes wear glasses at the same time 3 00d ball lenses, and the object at a distance of 5 meters lasts for 3 minutes, Then remove the closed lens of the right eye and check the visual acuity immediately, if the visual acuity is pseudomyopia, otherwise it is true myopia, and the left eye is examined in the same way.

Of the above three methods, dilated image refraction is the most accurate.

The difference between true myopia and false myopia is as follows: true myopia: generally divided into two kinds, commonly known as axial myopia and refractive myopia, axial myopia is the growth of the eye axis, true myopia is often the elongation of the eye axis causes the light to focus in front of the retina, in addition, because the refractive density of the whole eye increases, the parallel light rays are focused before the retina after passing through the eyeball, and the true myopia patients cannot be carried out by drugs**, after the use of muscle paralysis drugs, the myopia degree has not changed; Pseudomyopia:

Caused by muscle spasm and muscle strength enhancement of the ciliary muscle in the eye, pseudomyopia patients can improve the adjustment of the ciliary muscle and relax the adjustment of the ciliary muscle by applying paralyzing agents of the ciliary muscle, so as to reduce the degree, and even **, so pseudomyopia patients can not wear glasses. In general, patients with true myopia need glasses according to the final true power after the application of cycloplegic agents. When myopia occurs, most of it is pseudomyopia, and generally pseudomyopia exists for 2-3 months, and gradually changes to true myopia.

Therefore, many children and parents do not notice a very short period of pseudomyopia at the beginning, and then see a doctor after the child has true myopia, at this time, there is no way to solve it with drugs, only through glasses or surgery**.

In order to effectively distinguish between pseudomyopia and true myopia, it is necessary to conduct a professional test of visual acuity to make effective judgments, so as to achieve a more scientific, standardized and accurate distinguishing effect.

Therefore, we must pay attention to communicate with professionals to master effective vision protection, so that the protection of eyes can play an ideal role, and learn more from others, and pay attention to the following points.

1. Respond in a timely manner when talking.

First of all, we must know how to respond, if others are very interested in saying a lot of things, and you don't have any expression, it will make people feel very embarrassed or uninteresting, so that the light words can only end hastily, and it will not help your language communication, so you should respond to others in a timely manner when talking to others.

2. Communicate attitude and respect each other.

The attitude when communicating is also very important, you should communicate modestly and friendly with the other party when communicating, and respect each other when talking, keep the body leaning forward during the conversation, not leaning back, and you can't lean your whole body on the chair, so that the whole person will look lazy.

3. Know how to listen when talking.

Listening is also a point to pay attention to in communication, when talking to others, we must take into account the feelings of others, but also listen to what the other party expresses, so that we can better communicate in language, otherwise it is like "chicken and duck talking", so that communication can not achieve the effect at all, and it is easy to misunderstand.

4. Don't always be self-centered.

When talking, we should also pay attention to an important point, don't always think that what you say and do is very important, always take yourself as the center, and other people's is not important, this situation is to be eliminated, which can easily cause others to be disgusted, and will also leave a bad impression on others.
