1.Regular astigmatism.
It can be corrected with different cylindrical lenses according to the type of astigmatism and the degree of astigmatism. Convex column lens for farsighted astigmatism, concave column lens for myopic astigmatism.
Mild astigmatism does not need to be corrected if there are no clinical symptoms, and corrective glasses should also be worn if there is vision loss or symptoms of visual fatigue and visual interference.
Children, especially preschoolers, must adequately correct astigmatism to prevent the formation of amblyopia.
Before wearing, it should be refractioned, adolescents and children should be dilated refraction, and it can also be combined with the measurement of keratometer to understand the nature and degree of real astigmatism, and then combined with subjective audition, the prescription of glasses can be determined.
Patients with high astigmatism who cannot adapt to spectacles can be corrected with contact lenses.
2.Irregular astigmatism.
It is not easy to correct with lenses, and can be corrected with contact lenses.
3.Surgery. It is suitable for high astigmatism caused by congenital or acquired eye surgery such as cataract or corneal transplantation, such as excimer laser refractive corneal surgery, laser corneal thermoplasty, cornatotomy, etc.

The occurrence and development of myopia is an irreversible process, and once myopia occurs, there is no way to reverse it, and there is no way to reduce the degree of myopia. After the appearance of myopia in the eyes, it will seriously affect the normal work and life, so it is necessary to improve the vision and maintain the clear visual quality through various optical correction methods as soon as possible, including eyeglasses or contact lenses. Although surgery can also be considered after adulthood, you don't need to wear glasses after surgery, and your vision is normal, and you can see that myopia is **, but in fact, surgery does not change the fact of myopia, and surgery is just to change the refractive state of the eye, such as changing the thickness of the cornea, you can do without glasses, so that the vision is maintained in the normal range, but the eye axis is still long, that is, the eye is actually still in a myopic state.

When many people feel that they can't see clearly, they may simply think that it is due to myopia. At this point, if you go to an eye clinic for a vision exam, you may notice some degree of astigmatism. Only by distinguishing between diffuse light and myopia can vision be better corrected.
So how can you tell the difference between myopia and astigmatism?
How to tell the difference between myopia and astigmatism.
Myopia and astigmatism have different imaging principles, clinical manifestations, and correction methods. If there is no refractive eye, it is an emmetropic eye. The so-called emmetropia refers to the fact that when the eye is not adjusted, the parallel light enters the eye and passes through the refractive system of the eye, forming a clear image on the retina.
In the case of myopia, the imaging is in front of the retina. In the case of farsightedness, imaging is behind the retina. In the case of astigmatism, an image is formed on the retina, but instead of a focal point, a focal line is formed, and the distance between the two focal lines determines the degree of astigmatism.
The clinical presentation and correction methods also vary, ranging from decreased distance vision in patients with myopia, normal near vision, and mild visual fatigue in patients with myopia. At the same time, due to insufficient accommodation, the aggregation effect may be weakened, which can easily lead to exotropia or exotropia, and concave lens correction is required. However, in the case of low astigmatism, vision is usually not affected.
Moderate and high astigmatism can affect near and far vision. Patients with astigmatism often experience visual fatigue, which is more obvious than myopia symptoms, such as eye pain, headache, especially forehead pain, double shadow, short-distance work, etc., which need to be corrected by column lens.
Astigmatism requires glasses. Like myopia and farsightedness, astigmatism is a refractive error that can lead to vision loss. This is mainly due to the refractive error of the eyeball in a fixed position, so external light cannot be imaged on the retina.
After astigmatism has formed, the diagnosis can be confirmed by refraction, and glasses can be worn in a fixed axial position, so that the corrected visual acuity of the eye can reach normal. Astigmatism is more likely to cause visual fatigue and requires glasses to reduce the use of the eyes, which can control the increasing degree of astigmatism.
For adults with astigmatism less than 6 degrees and relatively stable astigmatism, vision can also be corrected with laser surgery.

This is already medium to high myopia and astigmatism, it is necessary to wear appropriate glasses, and then it also needs to cooperate:
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 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 moxibustion acupuncture points of Chinese medicine, combined with jujube Kuanhui medical 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 the nutrition of the eyes.
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 are still in the process of continuous development after birth, and the content of the examination is 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.
The visual acuity test sheet is also the result of the optometry examination, and the correct interpretation of the optometry examination results depends on the above data. Under normal circumstances, the results of an optometry examination usually have the following data: >>>More
In fact, I feel that feelings cannot be forced. If he doesn't love you, even if you get him, she won't cherish you, and it's still a woman who is pitiful. So I suggest that you don't act like a child in emotional matters, especially when it comes to marriage issues, and you can't be sloppy, at least the county understands his current situation and then makes a conclusion. >>>More
