RulesWhat glasses to wear for astigmatism, what is astigmatism, and what are its principles of glass

Astigmatism in the eye can be corrected with a cylindrical lens.

If it is not suitable for all corrections, it can be corrected with lower prescription glasses first, and then gradually increase the prescription, and if irregular astigmatism cannot be corrected with cylindrical lenses, it can be corrected with rigid contact lenses. Eyes have astigmatism, easy to see things, double vision, visual fatigue, and even headaches and other symptoms.

The principle of astigmatism.

1. Ordinary lenses can only correct regular astigmatism, not irregular astigmatism, and rigid contact lenses should be used for irregular astigmatism.

2. The effect of regular astigmatism patients corrected with ordinary lenses is also different. The greater the astigmatism, the worse the effect. In general, astigmatism below moderate is better corrected, while high astigmatism is difficult to correct to a satisfactory visual acuity.

In particular, those with high farsightedness and astigmatism cannot rely on adjustment to see objects clearly. If correction is not done as soon as possible in childhood, the development of visual function will be limited to a certain extent, and the corrected vision will be worse when you grow up, and moderate amblyopia may occur.

3. The situation of high myopia plus astigmatism will be a little better than farsightedness, although the distant can not see clearly, but the near can see more clearly, and the visual function can also get a certain exercise, the effect is better than the farsighted astigmatism, but it should also be corrected as soon as possible.

Therefore, we must develop good eye habits, look less at electronic products such as mobile phones and computers, take a break for nearly an hour or so, do eye exercises and massage or look into the distance for a while, do not use your eyes for too long, and often stay up late, usually you can do more outdoor activities, see more green plants, and eat more food that is good for your eyes.

If there is a flash, you can go to the hospital to have a good checkup, is there a flash of myopia and farsightedness at the same time? Glasses can also be worn.

Regular astigmatism does not have high requirements for glasses, and you can choose the right lenses and frames according to your own prescription, which can achieve a better correction effect.

If you reflect light, first of all, you should go to the optical store to check it, the light is better, because you have to check the degree to know, if you have astigmatism, you can bring some refraction.

If you want to wear glasses for regular astigmatism, it is best to go to a regular hospital for refraction before getting it.

It is safer to go to a regular eye hospital to get a lens and take it to the car, and you need astigmatism glasses for correction.

In the case of astigmatism, it is still necessary to see how much myopia is combined with myopia and astigmatism with glasses.

As long as it is a pair of glasses that are astigmatism with you, you can wear them, after all, wearing glasses makes your eyes less astigmatism.

It is best to wear light-concentrating glasses for astigmatism, but you can't buy them casually, it is best to go to a regular hospital or optical store for refraction, and then wear suitable glasses.

What kind of glasses are good for astigmatism, go to the optical store and ask, that is very professional No, you can also ask when you go to the hospital.

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.

The refractive state in which the eyeball has different refractive powers on different meridians, forming two focal lines and minimal diffuse spots is called astigmatism. According to the astigmatism axis, it can be divided into regular astigmatism, anti-regular astigmatism and oblique astigmatism. The principles of astigmatism correction are:

Regular astigmatism and oblique astigmatism are low-corrected, and anti-regular astigmatism is corrected, but it also depends on the try-on situation.

Do I need glasses for my astigmatism? Will it get deeper and deeper?

It is best to wear Gong Zhi because it is easy to wear it for a while and not wear it for a while, and the prescription is deeper, and often wearing astigmatism should be able to cure astigmatism. If you wear it, the degree will not increase quickly, whether it is concave or not, I don't know. But it doesn't matter if you have glasses that are lighter and more expensive, because the bridge of the nose will be concave faster after wearing it for a long time.

Should astigmatism be worn with glasses for a long time?

The physiological alteration of astigmatism produced by the human eye when fatigue can be recovered.

However, if the astigmatism exceeds 75 degrees or more, it is recommended that you must wear glasses to correct it! Otherwise, it will be even worse!

Do I have to be astigmatism with glasses???

If you are nearsighted, you can wear glasses.

Astigmatism lenses are different from normal lenses.

Should I wear glasses for astigmatism?

Low-grade astigmatism can be done without glasses, but according to the landlord's description, there is double vision, it is likely that it is not mild astigmatism, or other problems, it is recommended to go to the hospital for a detailed eye examination.

Do I need glasses for my astigmatism?

How many degrees of astigmatism? Moderate to high astigmatism can cause eye fatigue, so it is recommended to wear it; If you want to have low astigmatism, you can ignore the symptoms of fatigue and don't want to wear glasses.

Do I need glasses for mild astigmatism?

You can do without it, usually rest, don't lie on your side and watch TV, it will compress the optic nerve, and astigmatism will be more serious.

Astigmatism of the eye requires long-term wearing of the eye nucleus like a mirror.

You don't need to wear it, your prescription is still low, protect it well, you can recover, if you really can't do it, you can only wear glasses, but the prescription is as low as possible. Just look good in the frames.

Myopia plus astigmatism is a common vision problem that has a very significant impact on vision. In this case, wearing the right lenses can effectively improve vision and reduce visual fatigue and discomfort.

Specifically, for patients with myopia plus astigmatism, highly personalized lenses can be chosen. These lenses use advanced digital technology to be tailored to each individual's unique vision concerns to achieve the best possible vision.

In addition, the lenses can be equipped with a variety of anti-reflective technologies, such as super anti-glare, blue light resistance, and enhanced surface hardness, to effectively resist adverse ambient light and damage from electronic screens.

In general, for people with myopia and astigmatism, choosing the right lens is very crucial. Only by choosing highly personalized lenses can you truly enjoy the excellent visual effect and reduce visual fatigue and discomfort. Therefore, we should try our best to understand and choose the right lenses for ourselves to ensure that our vision problems are best solved.

Ordinary spectacle lenses can only correct regular astigmatism, but irregular astigmatism cannot be corrected with it, and the best way is to use rigid contact lenses to correct it, and the effect is better. The effect of correcting regular astigmatism with ordinary lenses is also different, the greater the astigmatism, the worse the effect, the less moderate astigmatism can generally be corrected to the normal value, while the high astigmatism is more difficult to correct to a good effect. If it is not corrected as soon as possible in early childhood, the development of visual function will be inhibited to a certain extent, and when you grow up with corrective glasses, the corrected vision will be worse, often forming moderate amblyopia.

High myopia astigmatism is better, although the vision is not clear, but the near vision is better, the visual function can also be exercised to a certain extent, and the corrected vision is generally better than the high hyperopic astigmatism. However, it is also necessary to correct it with glasses as soon as possible. Regardless of the high degree of astigmatism, the earlier the correction is made, the better.

Because of the early correction, it can not only promote the development of visual function, but also reduce the error response of object deformation and spatial positioning, and the degree to which the patient can bear it is also larger.

Backward astigmatism can be appropriately underweighted by some degrees, counter-gauge astigmatism and oblique axis astigmatism, and the general recommendation is foot correction.

For newly diagnosed patients or patients without a history of wearing cylindrical lenses, there will often be obvious discomfort during correction, even if only part of the cylindrical lens is given, although it can improve vision, but it may also cause symptoms such as visual distortion, if there is a history of cylindrical wearing, when the prescription needs to be adjusted, no matter whether there is a major change in astigmatism or axial direction, it will cause the patient's discomfort and symptoms, so the patient should be allowed to try on the flat ground and stairs to see if there is uneven slope of the road surface and stairs, Then, depending on the adaptation, see if the prescription needs to be adjusted.

Astigmatism glasses are based on foot-corrected glasses.

The degree is accurate, try to correct the foot, and the axis position should be correct.

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.
