What are the signs before becoming myopic and what are the precursors of myopia in the eye

First of all, in the face of a patient with low vision, it is relatively easy for an ophthalmologist to determine whether he has myopia, but it is important to note that it is not less than visual acuity to assume that there is no myopia, because for most students, normal vision can be achieved even, if their vision is just there, wear lenses of 50 to 100 degrees. can be reached, then it means that you are already short-sighted. It is relatively difficult for parents and students to determine whether they have myopia, and children should be vigilant if they have the following feelings:

1. Eyes often feel dry, tired, and even dizzy and nausea.

2. Sometimes the vision is blurry, but it can get better after resting.

3. I often have blurred vision, and I can't get better after resting.

4. See near clearly and far away clearly.

5. In order to see things in the distance, you must squint or squint**.

For the first two conditions, it is generally considered to be a precursor to myopia, and if you don't pay attention to it, you will get myopia; In the latter two cases, it is almost certain that you have myopia and should go to the hospital for examination as soon as possible.

Secondly, to distinguish between true myopia and pseudomyopia, this work needs to be done by a specialized ophthalmologist, from a strict medical point of view to distinguish whether there is true myopia, that is, to carry out adequate dilated refraction, but unless the patient needs and requires glasses, it is not only of great significance to the diagnosis, but also because of the long-term mydriatic effect of atropine to the patient's study and life. Therefore, as an ophthalmologist, it is important to find out the patient's intentions before deciding whether to perform dilated refraction.

The causes of myopia are related to genetic and acquired environmental factors. Heredity is innate and irreversible. The most important factor in the development of myopia is the use of the eyes by students for a long time, such as writing, playing computers, playing games, etc.

The student's prolonged close use of the eye makes it necessary to thicken the lens. Over time, the lens cannot return to its original state, and when the intersection is moved to the front of the retina, myopia is formed.

Common manifestations are:

1. Visual acuity: distance vision is reduced, near vision is normal.

2. Visual fatigue: low myopia is common, and it is lighter than high myopia. Feeling soreness in both eyes, dry eyes, squinting movements, and occasional headaches.

3. Ocular deviation: It is more common in people with high myopia, and due to the corresponding weakening of the collection function, it is easy to cause exotropia or exotropia, and the strabismus eye is mostly a eye with a high degree of myopia.

4. Eye changes: Because the anterior and posterior diameter of the eyeball becomes longer, the eyeball is more prominent, and the person with high myopia is more obvious.

Therefore, if myopia occurs, it is necessary to pay attention to it and correct it in time.

1. If it has affected daily vision, then you need to go to the hospital for accurate refraction and then wear appropriate glasses.

2. Correct daily bad eye habits and pay attention to developing good living habits.

3. Insist on doing eye exercises every day.

Fourth, timely supplement the eye vision nutrients to supplement the nutrients needed by the eyes, so as to better control or improve the myopia of the eyes.

5. Have a certain amount of outdoor activities every day and see more green plants.

6. Check your eyesight regularly.

1. Eye fatigue.

Some elementary or middle school students in the upper grades will have overlapping handwriting after reading a book for a long time, and when they look up at the objects in front of them, they will feel as if they are about to leave and float unsteadily. Some people look far away and then move their vision to a near object, or after a long time of looking at a distant object and then move to a distant object, and the vision is blurred for a short time. These are signs of dysregulation of the ciliary muscles of the eye, which are caused by eye fatigue.

In addition, some children and adolescents will have chalazion, stye or blepharitis. Although these children can achieve above the eyesight, they have actually "played" the prelude to myopia.

2. Perceptual hypersensitivity.

At the same time as eye fatigue, many people are also accompanied by burning, itching, dryness, carbuncle swelling, and in severe cases, the pain spreads to the deep part of the eye socket, and even causes migraine, and can also cause soreness in the occipital, neck, shoulders and back, which is caused by fatigue hypersensitivity in the sensory nerves of the eyes.

3. Systemic nervous disorders.

It turns out that children with good grades will be bored with learning, lack of attention and concentration when listening to lectures, and their reactions will be a little sluggish, their temper will become irritable, and they will lack interest in the things they originally liked, and their academic performance will decline. When you sleep at night, you have a lot of dreams and sweats, and your body is easily tired, and you have symptoms such as dizziness and loss of appetite. These slowed erection are also signs of imminent myopia. Hope.

Myopia is very common in today's life, and once it occurs, the patient's visual function will decline, and it will need to be improved by wearing glasses. Then we must have a basic understanding of the reasonable improvement of myopia. The most important thing is that the signs of pre-myopia are the most important issues to pay attention to, and next, we will understand what are the three major signs of pre-myopia?

Clause. 1. Squinting patients will not be able to see the distance clearly after myopia, and at this time they need to make up for it by squinting, in fact, this phenomenon is the manifestation of most myopia.

Clause. Second, rubbing your eyes to see the target clearly, you will improve your adaptability by rubbing your eyes, in fact, this method of rubbing your eyes has no effect.

Clause. Third, it is blinking, frequent blinking can alleviate myopia to a certain extent, increase the clarity of vision, many people will see things more clearly when they are crying, which is also the main manifestation of the early signs of myopia.

Vision is very important to us human beings, and the visual function is affected, and it will bring more and more problems, so we should pay more attention to the reasonable adjustment of the visual function. There will be many characteristics after the myopia function problems, such as the patient will see more and more blurry, and even feel the fatigue of vision, these are the problems of myopia, there are many early signs of myopia, as long as the limbs can be detected in time, the use of reasonable methods to improve will not be too much of a problem. Here, patients should be reminded that the impact of myopia on visual function will become more and more serious, so do not ignore the harm of myopia, and take the best measures as soon as possible.

To prevent problems with vision function, it is important to understand not only the symptoms but also the appropriate prevention methods. In our country, the probability of myopia in children is gradually increasing, which is caused by the fact that children do not pay attention from an early age, and parents should train their children to have a good habit of using their eyes at an early age, so that it is not easy to make problems happen.

Hello, the following conditions in children are generally signs of myopia.

Squinting: When distant targets cannot be seen clearly, children often resort to squinting to compensate, because the eyelids can block part of the pupil when squinting, reducing diffuse light and reducing the impact of astigmatism, thereby temporarily increasing and improving visual acuity.

Blinking: Frequent blinking can alleviate myopia and increase visual clarity in certain procedures. Many people will see things more clearly when they are in tears.

Rubbing your eyes: When you can't see the target clearly, you often rub your eyes with your hands to try to see better.

Tilting the head: It often happens to tilt the head to watch TV, and it is also because when the head is tilted, it can reduce the interference and influence of some diffuse light, and some children will even develop the habit of tilting their head.

Frowning: Frowning in an attempt to improve vision by "straining" both eyes. However, in fact, because the extraocular muscles compress the eyeball, the development of myopia is accelerated.

Wrenching: When a small number of children can't see distant targets clearly, they often use their hands at the outer corners of their eyes and pull the corners of their eyes outward to achieve the same effect as tilting their heads and squinting.

Strabismus: Some myopic children have exotropia, where one eye looks straight ahead and the other eye turns outward. Therefore, when you notice eye squint, you must also check your vision first.

Close to the TV: It is often manifested in the close side of the TV when watching TV, as close as possible to the TV, and when watching and writing. Lying very close, very low.

Complaints: Due to unstable vision, some children will complain that the classroom is too dim, or that they cannot see clearly due to the reflection of the blackboard, and many children will say that their eyesight is poor during self-study at night.

Mistakes: The target is not clear in the distance, and I don't say hello when I see an acquaintance. I make mistakes during exams, I can trip over or hurt myself when I move in the dark, and some of them have a decline in academic performance, and I often have to borrow other people's notes to copy, etc.

Experts from Wuhan visual defense told us that there are signs and signals for the occurrence of myopia, first of all, the phenomenon of eye fatigue: it is manifested as the phenomenon of ghosting and floating instability when reading a book. When looking far away for a long time and then turning to see near, or when looking near for a long time and then turning to see far, there will be a temporary blurring in front of the eyes, which is eye fatigue caused by adjustment failure.

The first symptoms of 40 percent of adolescents are not necessarily vision loss, but symptoms caused by neurological disorders, such as hypersensitivity of the ocular sensory nerves, dry, burning, itchy and painful eyes, and some even cause migraines. Symptoms of systemic nervous disorders: students will be bored with learning, lack of concentration in lectures, slow reactions, irritable temper, dreaming and sweating when sleeping at night, and the body is prone to fatigue, dizziness, loss of appetite, etc.

However, when these symptoms appear, it is difficult for students and parents to associate these symptoms with myopia, so the early prevention of myopia is often missed. It is very important to understand the aura symptoms of myopia, pay attention to capture the early signals of myopia, and do a biological test of eye refractive elements when the aura symptoms appear, which is very important for early prevention of myopia!

1. Eye fatigue. When you read a book for a long time, the handwriting overlaps and serially, or when you look up at the object in front of you, and you feel that it is imminent and unstable, you need to pay attention to it. When you look at a near object after a long period of time, or when you look at a distant object after a long time of viewing, you will have a brief blurred vision.

These are all manifestations of dysfunction of the ciliary muscle of the eye, which is caused by eye fatigue and is the "sonata overture" to myopia.

2) Systemic neurological disorders. I used to have good grades, but I suddenly became bored with studying, my attention was lost when I listened to lectures, my reaction was a little slow, my temper became irritable, I lacked interest in the things I used to love, and my academic performance declined. Dreaming and sweating when sleeping at night, the body is easily tired, and dizziness and loss of appetite are also very good.

These changes are also a sign of myopia.

3) Hypersesis. At the same time as eye fatigue, it will also be accompanied by burning, itching, dryness, swelling and pain in the eyes, and in severe cases, the pain will radiate to the deep orbit, and even cause migraine, and can also cause soreness in the occipital, neck, shoulders and back. This is due to fatigue hypersensitivity in the sensory nerves of the eye.

4) Miscellaneous. Negative chalazion, stye or blepharitis, although visual acuity can be above and above, is often the beginning of myopia.

Nowadays, there are more and more people with myopia, and the age of myopia is getting younger and younger, and many children are myopic early, so when children have the above signs, parents must pay attention.

The commonly used methods to protect eyesight and prevent myopia are:

1. When reading and writing, do not lie on the table and tilt your head to study, let alone lie down or sit in the car to read, and the posture of reading and writing must be correct.

2. When writing and reading, keep the distance between the body and about 30 cm.

3. Don't use your eyes for a long time, especially when using the computer, watching TV, watching and writing, it is best not to exceed 40 minutes in a continuous time, and you should rest for about 10 minutes after using your eyes, do eye exercises, look at the green scenery in the distance, or close your eyes and take a break.

4. The indoor light should be sufficient and soft. If you can't study in strong sunlight, you can choose a non-flickering lamp, such as an incandescent lamp.

5. Eat a balanced diet, don't be picky, and eat more foods that are good for your eyes, such as carrots, tomatoes, corn, spinach and other red foods, all of which have a health care effect on your eyes.

6. Regularly supplement vision nutrients to enhance the anti-fatigue ability of the eyes and prevent the occurrence of myopia. Generally, doctors recommend taking two packs of Vision Nutrients a day, and insist on taking them for a period of time, which can protect your eyesight and prevent the occurrence of myopia.

Hello, myopia precursors include many aspects, when it first occurs, the patient will feel that the observation of things is sometimes clear, sometimes blurry, and the observation of near is clearer, but the head of the head** distant things are not very clear, and the time is a little longer and feels more tired. In addition, if the child's academic performance was good before, and the sudden decline in academic performance may be caused by myopia, which causes the child's academic performance to decline when looking at the blackboard. Therefore, once you feel that your eyes are not clear and uncomfortable, or even your grades are declining, it may be a precursor to myopia, and it is recommended that parents take their children to a regular hospital for examination in time.

The precursor of myopia is most likely to occur through computer refraction, but after resting and then doing an examination, the power of the eye will change or decrease, and most of it is due to fatigue caused by adjustment disorders, resulting in false components in the eyes.
