What is astigmatism? How can I prevent it? 5

How to recover the deformation of the eyes with glasses, are you still paying attention to it?

Develop good eye habits.

Sit upright. Sitting posture should be correct and comfortable when working. The center of the computer screen should be installed on the same level as the operator's chest, the distance between the eyes and the screen should be kept at 40 50 cm, and a chair that can be adjusted in height should be used.

During eye use, you should blink frequently or close your eyes for a while to rest for a while to regulate and improve your vision and prevent vision loss.

Combine work and rest. Generally speaking, computer operators should take a break for about 10 minutes after working for 1 hour and go outside to exercise their hands, feet and body, such as walking, doing radio exercises, taking active rest, or doing eye exercises and moving their heads indoors.

Use eye hygiene. Instruct young children to practice good hygiene and avoid touching their eyes with their hands or other objects to avoid infection.

Eye diseases. Accurate spectacle dispensing.

In the work, it is common to see that the glasses are not suitable, such as astigmatism axis deviation, horizontal axis inconsistency, pupillary distance inconsistency, etc., which affect vision correction, so astigmatism patients must choose professional ophthalmology and accurate optometry.

Glasses are then prescribed according to the prescription.

Be aware of the environment. When reading a book or working at close range, the indoor light should be suitable, not too bright or too dark;

Regularly remove dust and microorganisms from the room, and use a damp cloth or wet mop when cleaning and hygiene;

Disinfect the air filter.

Treatment, reasonable adjustment of air volume, change of fresh air.

**: Genetic factors.

Most astigmatism is congenital, and children and adolescents with astigmatism in either parent have a higher rate of astigmatism than those without both parents.

Environmental factors. Diseases, trauma, surgery, etc. can lead to changes in the curvature of the cornea and lens, causing astigmatism;

Both extraocular muscle tone and eyelid pressure can affect corneal shape, leading to astigmatism;

Poor eye habits and lack of outdoor activities can also contribute to the formation of astigmatism.

Typical symptoms: blurred vision.

Blurred vision is closely related to the degree and type of astigmatism. People with mild astigmatism generally have unaffected visual acuity, and moderate to high astigmatism has poor far and near vision.

Vision loss. Simple astigmatism has mild vision loss, refolding astigmatism, especially significant mixed astigmatism, vision loss is more severe, and amblyopia is easy to form due to poor correction.

Eye fatigue. Most commonly, it presents with eye pain, headache (especially on the forehead), double vision, and eye swelling after a slightly longer period of near work. Patients with astigmatism, especially farsighted astigmatism, are susceptible to eye fatigue due to the constant fine adjustment of blurry images on the retina and the possible distortion of vision.

Maintaining good lifestyle habits can effectively prevent its occurrence and progression. After suffering from astigmatism, it should be corrected in a timely manner.

Astigmatism is a type of refractive error of the eye, and there is a certain relationship between astigmatism and the curvature of the cornea. The cause of astigmatism is that the curvature of the cornea is uneven, so that the light cannot be accurately focused on the retina, so that a clear image cannot be formed, which is called astigmatism. Therefore, we should pay attention to our eyes, and if the above conditions occur, we should go to a regular hospital for examination in time.

Let's take a look at the causes of regular astigmatism, which is mostly caused by corneal congenital anomalines, and some patients may also have lens astigmatism. There are also some acquired astigmatism, such as long needle eye or miliary eyelids, long-term poor eye posture, such as frequent squinting, eye rubbing, lying down to read, etc., so that the eyelid compression of the cornea will also change the corneal curvature, astigmatism and increase the degree of astigmatism. In addition, certain eye surgeries, such as cataract and corneal surgery, may also alter the degree and axis of astigmatism.

Astigmatism is usually caused by irregular corneal morphology, which is divided into physiological astigmatism and acquired astigmatism according to the different conditions, so there is no way to prevent this situation, but to correct it as soon as possible after astigmatism occurs, so as to avoid the damage caused by astigmatism to the eyes, which is more important.

Because patients with eye diseases often lie down to read books and watch TV, the elasticity of the suspensory ligament in the eye is uneven, resulting in inconsistent overall curvature of the intraocular lens, resulting in myopic astigmatism. For astigmatism, you can choose advanced technologies such as femtosecond laser surgery and excimer laser surgery, and you can achieve better results for astigmatism, but its sequelae are still uncertain.

Astigmatism, myopia and farsightedness are all not well formed by the eyes, and there is a problem with the use of points, so we must pay attention to eye hygiene, and we must not make the eyes tired? Myopia is the cause of excessive use of eyes, farsightedness is also the cause of aging, astigmatism, it is also caused forever, so we must pay attention to the point, always hygiene must pay attention to eye habits, or when using the eyes, we must not let the eyes too tired, eye fatigue, it will cause myopia and farsightedness, but also cause astigmatism, pay attention to eye hygiene.

Astigmatism is the lack of focus of the eyes and the inability to see clearly, which should be corrected by wearing glasses. Don't read in bright light, especially in sunlight or dark places at night.

How does astigmatism occur? What will happen? How can it be prevented? I think you have to pay attention to flashes, to prevent myopia, and to wear polarizers.

If you want to prevent astigmatism, you should ensure that you have enough light when reading a book or watching TV, and you should also avoid using your eyes for too long to prevent eye fatigue. When reading, make sure that you sit in an upright posture and that the distance between the book and your eyes is moderate, usually about 30 cm. Don't watch TV too closely, and get enough sleep.

Astigmatism is one of the common types of refractive error of the eye, many people have such troubles, astigmatism will not only have an impact on the health of the eyes, but also bring great pain and suffering to the patient. Therefore, it is necessary to do a good job of prevention in daily life, which can reduce the incidence of astigmatism. If you want to pay attention to not being able to look at your phone and computer regularly, you must mainly suppress the time in the process of using it, and at the same time, you should also pay attention to the posture of looking at your phone and looking at the computer, not too close, and you should also pay attention to not working overtime for a long time.

Special statement: Pay attention not to turn off the lights at night to play with mobile phones and play with mobile phones for a long time, which is not conducive to eye protection.

1. When reading a book, the light should be sufficient, and the light should come from the left rear; Reading posture should be correct and kept between 30 cm and 40 cm to prevent astigmatism.

2. Don't read in a rocking car, and don't lie down to read.

3. When choosing reading materials, the font should be clear and not too small.

4. Pay attention to observation, find any problems, and take them to the eye hospital for examination.

5. It is best to have the first full eye examination at the age of 3-4 years, and then regular eye examination 1-2 times a year.

6. Go to the suburbs more, see more green wilderness in the distance, protect your eyesight, and prevent astigmatism.

7. The height of the TV is a little below the parallel line of the eyes, and it must be 5-7 times the diagonal of the TV picture to effectively prevent astigmatism.

Recommendation: Most astigmatism is related to genetic factors, but maintaining good lifestyle habits can prevent the occurrence and development of astigmatism. For example, pay attention to eye hygiene in daily life, avoid rubbing your eyes with your hands and other items touching your eyes, when reading and writing, maintain a correct sitting posture and the distance between your eyes and objects is not too close, happy, but also pay attention not to overuse your eyes, avoid eye fatigue, and rest your eyes for about 1 hour.

Children with nearsightedness or farsightedness should visit the ophthalmologist regularly and wear proper glasses.

Astigmatism is actually a very common phenomenon, it can be said that astigmatism within 100 ° is almost all of us, and this can be used without **.

But if it is a relatively high number of astigmatism, it is recommended that it should be **, because it can cause our eyes to be particularly fatigued, and some people will have a headache after reading a book, why? In fact, it may be the cause of astigmatism.

Astigmatism is not only treatable, but also curable, and there are 3 most common ways:

The first is to wear glasses, which is completely fine for low-degree astigmatism. Then, with more eye exercise, more outdoors, and supplementing the comprehensive nutrition of the eyes with Leyan Vision Nutrients, then it is natural to gradually recover astigmatism!

The second is the excimer laser, which is the kind of laser machine that we often say for laser treatment of myopia, which can also be used for astigmatism.

The third is that some elderly people combine cataract and astigmatism at the same time, and this part of the population can choose a special intraocular lens to correct astigmatism in the process of cataract surgery, and at the same time, the astigmatism can also be cured in the process of curing cataract, killing two birds with one stone.

At present, major astigmatism can only be corrected with glasses. After regular astigmatism, it is corrected with a cylindrical lens of appropriate power or a spherical combined cylindrical lens; Irregular astigmatism can be corrected with contact lenses.

Children's astigmatism, mainly depends on the quality of vision, and the severity of visual fatigue, if the child is regular astigmatism, does not cause visual impairment, no visual fatigue can not be treated. If the child has visual fatigue, regardless of the degree of astigmatism, even if the astigmatism is very mild, dilated refraction is required, and appropriate corrective glasses are required. In principle, all astigmatism should be corrected, but if the child's astigmatism is too high to adapt, you can wear low-degree corrective glasses first, slowly adapt, and then wear glasses with all the height corrected.

Maintain a good working posture. Maintaining an optimal posture with both eyes at eye level or slightly downward at the phosphor screen will ease the neck muscles and minimize the area of the eyeball exposed to air.

How to prevent astigmatism, read by yourself for more than an hour, and take a 5-minute break every 30 minutes. Nutrition should be balanced. Go to the countryside and see more distant and green plants.

For friends of the mobile phone family, don't read in the rocking car, and don't lie down to read.

How to prevent astigmatism, parents should guide young children to develop good hygiene habits, not to touch the eyes with their hands or chemicals casually, so as to avoid the infection of eye diseases, if infected with eye diseases, try to go out as much as possible. For the prevention of astigmatism, it is also necessary to pay attention to the font when choosing reading materials, which should be clear and not too small.

How to prevent astigmatism, for people who sit on the computer for a long time, adjust the distance position of the phosphor screen. It is recommended that the screen color be adjusted to the color that is most comfortable for the eyes. The recommended distance is 50-70 cm, while the phosphor screen should be slightly 10-20 cm below the eye level, with a downward viewing angle of 15-20 degrees.

Because the angle and distance can reduce the need for refraction, the chance of eye fatigue is reduced.

This phenomenon is not normal and may be caused by temporary lens astigmatism caused by too rapid changes in power. Don't rush to apply this astigmatism to glasses, pay attention to standardize visual behavior, and avoid eye fatigue ......After a period of stability, retest. It is estimated that this astigmatism will disappear or decrease, and it will be fixed when it is attached to the glasses!

If your astigmatism increases too quickly, you may be suspected of keratoconus. It is advisable to go to an eye specialist hospital to rule out that your eye is keratoconus.

Glasses, scientific optometry glasses, so that the eyes are in a comfortable environment, is conducive to myopia.

Wear appropriate corrective glasses and wait for laser surgery to rule out contraindications in adulthood.

Astigmatism refers to the disorderly vision, which is caused by the improper curvature of the cornea, and the problem of astigmatism often appears in children and adolescents, and the factors that cause astigmatism are as follows:

1. The change of astigmatism during myopia, the eyes look inward and downward, and the eyeball rotates at the same time, which is the change of the astigmatism axis of the eye, so the appropriate lenses can be selected according to the different ages, focus depth and relative adjustment force of the patient.

2. The symptoms of visual fatigue are usually related to age and the nature of the work, the older the person, the person who writes at the desk, will cause mild to moderate astigmatism, if it is lower than the normal value, it needs to be corrected.

3. The impact of spectacle lenses is due to the uneven size effect of the glasses around the moving lens surface, and sometimes the size of the frame may also affect the peripheral optics and cause astigmatism.

If you have astigmatism, there is no good way to do it now, mainly depending on whether your astigmatism is caused by congenital or acquired.

If it is acquired, astigmatism is generally accompanied by myopia. So if you are pseudomyopia, you should pay more attention to rest and reduce eye fatigue, so that myopia and astigmatism will be alleviated to a certain extent. So if you are true myopia, you may need to wear glasses, and then go to the hospital ophthalmology department for a one-step examination, then targeted**, so that the astigmatism of the eyes can also be alleviated to a certain extent.
