If you wear and take off like this, take off and take it off, the prescription of the glasses will increase faster. Now that the eye has changed, you should insist on wearing glasses as the doctor and optician say. When it's time for life, go to the hospital for an operation, and the glasses can be removed.

If the astigmatism is more than 100 degrees, then the astigmatism will be counted in the glasses.
Studies have shown that the common manifestations of astigmatism in the eyes are:
1. The blurred image on the retina needs to be constantly finely adjusted, and the vision is distorted, so astigmatism, especially for farsighted astigmatism, is prone to visual fatigue. Presents with eye pain, tearing, headache, especially in the forehead, double vision, and short-range work that cannot be sustained.
2. Patients with highly asymmetrical astigmatism in both eyes, in order to see more clearly, often adopt a tilted head position to cause strabismus, which can be recovered after astigmatism correction. Patients sometimes move objects closer to the same place as a nearsighted person in order to obtain a larger image of the retina.
3. People with high astigmatism often squint when looking at distant or near targets, so as to achieve pinholes and fissures to improve their vision. Seeing through pinholes or fissures can reduce the impact of astigmatism on vision.
Astigmatism refers to when the eye is adjusted to rest, after the parallel light rays are refracted by the eye, due to the different refractive power of each meridian of the refractive system, causing different degrees of convergence, so it can not be concentrated on the retina, but at different distances to form two intersecting lines, the distance between the two intersecting lines represents the degree of astigmatism, because the retina is only presented as a hazy ring or a line, so the patient feels blurred regardless of farsightedness and near-sightedness.
Astigmatism**:
1 Mild regular astigmatism does not need to be corrected if there is no eye fatigue or blurred vision, but if there is any discomfort above, it should be corrected even if the prescription is not high.
2 High astigmatism should be corrected with cylindrical scope, if not suitable for all correction, can be given a lower degree, the general common method is to take drugs, usually the doctor recommends taking Leyan vision nutrients, warm water, insist on taking for a period of time, astigmatism can be reduced.
3 Irregular astigmatism cannot be corrected with a cylindrical lens, and contact lenses can be tried.
-
Astigmatism is not very common.
Don't look at your computer or phone for a long time.
Don't be serious, just be honest.
-
Astigmatism is a very normal refractive error, more than half of people will have astigmatism, poor vision is prescribed glasses, there is no other way.
-
Please go to a regular hospital for examination. Mild astigmatism is negligible, and moderate astigmatism or more requires glasses to correct.

Whether you have myopia or astigmatism is not your own judgment, but needs to be examined by an optometrist. Because you are only 18 years old and are still minors, just because you didn't have myopia before doesn't mean you don't have myopia now. In the case of the ciliary muscle accommodative effect is stationary, distant parallel rays cannot be focused on the retina, but focused in front of the retina is called myopia, focused behind the retina is called hyperopia, can not form a focal point but forms two focal lines in front of and one after the other is called astigmatism, and the above is collectively referred to as refractive error.
As long as you have refractive error, you will have blurred vision, and sometimes you will feel that there is double vision in your vision, especially mild refractive error, which is not a phenomenon unique to astigmatism.
There are many theories about the causes of myopia, but one thing in common is that prolonged close use of the eye can lead to myopia. Myopia is divided into axial myopia (the axial axis is too long, and the axial axis increases by 1 mm), curvature myopia (corneal curvature increases by 1 mm), and refractive index myopia. One of the oldest theories of myopia formation holds that the eye needs the ciliary muscle to contract to change the curvature of the lens to make the object image on the retina to see the object clearly, and the long-term close use of the eye causes the ciliary muscle to spasm, so that the lens can not be flattened, causing the distant object to focus in front of the retina to form pseudomyopia, and the pseudomyopia will lead to physiological changes in the refractive system of the eye to form true myopia, which is irreversible.
Although the latest view is that this statement is not comprehensive, it still acknowledges that prolonged close use of the eye can indeed lead to myopia.
Therefore, the main reason for the formation of myopia is prolonged close eye use. I don't know how long you feel that you don't know how long you can see distant objects, if it has just been a few days, then it should be pseudomyopia caused by eye fatigue, or it is called accommodative myopia, if the eyes are relaxed (only by reducing the use of near eyes, more vision of distant objects can be relaxed), this phenomenon can be eliminated, but because you should pay attention to eye hygiene in the future. If this phenomenon has been present for about half a year, then it is recommended that you go for an optometry examination, or the possibility of pseudomyopia is not very likely.
I have no objection to some auxiliary methods such as massage in traditional Chinese medicine, which has a good relaxing effect on pseudomyopia, but if you can insist on doing eye exercises, it is estimated that this cost can be saved. But it is impossible to count on the use of adjunctive means such as massage to ** true myopia.

1. Check whether it is pseudomyopia, if it is pseudomyopia, you can recover by paying more attention to rest.
2. If it is astigmatism, usually the eyes should not be too tired, pay more attention to the eye rest, you can wear the eyes, the time is not too long, otherwise there will be dependence, you can recover.

Let's wear glasses! I'm also a high school student, and my degree rises very slowly in high school!

Do you do eye exercises? Stick to it.
There is also the need to look at green objects, from far to near.
Look helps with eyesight**.
Always take care of your eyes.
It's best not to bring eyes.
Communicate more with your child, and don't let him go home at night. In addition, you must communicate with other children's parents, and you can't just stay with your children and take a salary from the bottom of the kettle.
1. Empathy: I can't always get up the energy to study, and I have a headache when I talk about learning, which makes you very melancholy, right? >>>More
The process has to be experienced: prove that you have grown up a little bit, start to grow branches, gently break them off and continue to grow. It's normal to be a little rebellious, don't be afraid, face your heart, face the growth process, actively explore knowledge, all good things are in front of you, come on.
Now going to school does cause a lot of pressure on some children, especially for junior high school and high school students with poor grades, the more parents ask for learning, the worse their academic performance, and even get bored of learning, and have resistance, how to resolutely this situation, there are two programs to try. >>>More
What you lack the most is that you are unwilling to interact with your classmates, to put it in layman's terms, you are willing to be alone, as if the speech and behavior of the whole class, and who has good academic performance and who has slightly worse grades, has nothing to do with you. You just pay attention to how you are, you don't want to have intersections with your classmates, so there are so many classmates who can play together, why do you take care of you? I'm guessing you were born withdrawn. >>>More
