How long does it take to dilate the pupil again after one dilation? According to the test results, g

Generally, the short-acting mydriatic drug is compound topicamide, the action time is generally 4-6 hours, the pupils are generally not dilated over 16 years old, and the mydriatic drug is ciliary muscle with atropine under the age of eight, the purpose is to check the refractive status of the macula, and the results of the eyes after the mydriatic pupils are not necessarily fully accepted, so it is still necessary to audition for re-examination, and the time interval between the two mydriatic pupils is not required, but if you suspect that the refraction is not accurate, you can take the original dilated eye sheet and go for re-examination, it is also possible. Of course, short-acting mydriatic agents are also used as eye water for myopia, so there is no need to worry about the damage to the eyes caused by two mydriasis!

You should use a rapid dilation of the pupils, that into the day of tomorrow can be recovered, the pupils are not harmful to the eyes, so you have no problem in the bracket every day or two, there is a try-on in the process of professional glasses, it is a good optometry, give you the prescription will let you try to take your reading is not suitable will be changed, the glasses must be comfortable, and then you can see clearly, it is the concept of Chinese glasses, new glasses must have an adaptation process, you can first go to the place where you are fitted with glasses to communicate, generally let customers adapt to about 1 week, If they don't fit in, they should give you a free replacement of glasses. There is also that you can see far more clearly, that is, if there is a shadow in the near future, it is related to many factors, can you say the specific point, such as how long you wear glasses, how much the eye reading has increased this time, whether there is astigmatism, the first time you wear glasses, you must adapt, if the previous reading is very low, this time it will be uncomfortable to adapt, astigmatism if you look at things obliquely, it will be deformed, it is recommended that you first go to communicate with the place with glasses, and then solve, Like a Chinese eye shop or a hospital, he can't say that the glasses don't matter.

In order to be accurate, it should be expanded twice, at least seven days apart. After dilating the pupils, the common sense is much blurred than usual, and it is especially dangerous not to look at things that are too bright in the sun.

In fact, dilated pupils and optometry tests are relatively high, and the next time you have optometry, you just need to go to a large optical store for examination, as long as he uses imports, and the prescription is more comfortable than your optometry in the hospital.

If you only wear glasses, you will feel dizzy and uncomfortable. It means that the refraction is not very accurate. It is best to go to a specialist hospital for optometry. Generally, before the age of 18, it is recommended that you have an optometry test once every six months, and if the prescription grows quickly, you have to listen to the doctor.

I'm in a similar situation to you, I suggest you buy contact lenses, go to the treasure island optical store to match it, pay attention to hygiene, and change the potion every day. You can wear brown and it won't be very fake. About 200 yuan is fine, and don't wear it when the aunt comes and has a cold!

1. Reasons for dilating the pupil to examine the eyes:

1. Pupillary dilation test is also known as pupillary dilation or nodal muscle palsy test in some places. This is a method of difusing the pupil through eye drops, allowing the doctor to examine the eye more thoroughly. A person's pupil is like the door of a room, when an ophthalmologist wants to know the situation in the eye, they need to open the door so that the light can fully shine into the eye, which is one of the reasons why the pupil dilation test is so important, the pupil dilation test is so important in order to examine the eye more comprehensively and find the corresponding diseases.

2. Pupil dilation is usually forced to relax the eye through cycloplegia, and no longer uses adjustment to achieve the true refractive state of the eye. This is one way that adolescents and children aged 15 and under need to do when they get optometry. True myopia and false myopia can be distinguished by pupil refraction.

In general, it does not cause harm to children's eyes. Because the pupil dilated refraction should be preceded by a routine intraocular pressure measurement. If the intraocular pressure is at a critical level or above normal, doctors do not recommend refraction of the pupil dilation.

3. Pupil dilation examination is conducive to the timely detection of fundus diseases in adolescents, and early diagnosis and early diagnosis, which can avoid the occurrence of some fundus complications. In particular, some patients have vision that cannot be corrected with glasses, so doctors need a pupil dilation test to remove organic lesions in the fundus; In a pupillary dilation test, an ophthalmologist can find many problems that are easily overlooked. Ophthalmologists can detect damage or abnormalities in blood vessels caused by diabetes and intervene in time to prevent the disease from developing.

Second, the pupil dilation test brings discomfort to people, and it has an impact on vision just after it is done, and it recovers soon after.

While pupil dilation tests may cause these minor discomforts, their clinical value should not be overlooked. Because of the impact of the pupil dilation test on vision, it is best to have a friend or family member accompany you after the test. If people want to maintain good vision and avoid serious eye problems, they need an ophthalmologist to fully understand the world as you see it and not let them examine it only through small pupils.

Whether the pupil can be dilated or not still requires a detailed examination by a doctor before the pupil is dilated.

Pupil dilation is not harmful to the eyes. First of all, before dilating the pupils, an anterior segment examination is performed to see if there is a possibility of glaucoma. These include the depth of the anterior chamber, whether the iris is bulging or flat, and so on.

Second, intraocular pressure measurement is performed before pupil dilation. If the IOP value is high or at the upper limit of the normal range, pupil dilation is not recommended. Finally, there are two needs for pupil dilation:

Clause. 1. Dilated refraction. Because children are more active in eye accommodation, the refraction results are not credible, and the pupils are generally not dilated.

Second, it is necessary to carry out a detailed and strict examination before the pupils can be dilated.

This is because the eye dilation examination allows the doctor to examine the inside of the eye more comprehensively. Imagine if you want to see what's inside the room, you have to open the door and let the light in to see better. The same is true for pupil dilation.

Generally, the dilated pupil examination will not cause damage to the eyes, but will only cause mild discomfort.

This is because by dilatating the pupil, the light can fully shine into the eyes, and the condition of the eyes can be checked more comprehensively; It can cause vision loss, blurred eyes, and temporary photophobia.

Pupil dilation examination can more comprehensively check whether there is a problem in the eye, which will make the eyes very sensitive, easy to lead to acute glaucoma, easy to cause eye redness, will make the eyes allergic, easy to lead to the growth of bacteria in the eyes.

Because in this way, you can check your eyes and find some injuries and diseases behind your eyes. There is no harm as it is a very healthy mode of examination and does not affect the vision of the eye at all.

Pupil dilation is harmful to the eyes.

Hyperopia greater than 300 degrees, because the higher the degree of hyperopia, the greater the accommodative power. Co-rotating esotropia, in which the ciliary muscles are completely paralyzed, can distinguish the nature of strabismus from primary or secondary strabismus. This provides an indispensable clinical basis for the selection of the best regimen.

Because primary strabismus often requires surgical intervention**, secondary strabismus only requires glasses**.

The purpose of refraction is to determine the refractive status of the eye, whether there is a refractive error, the type of refractive error and its degree. The prescription of glasses is determined according to the refraction results, so whether the refraction is accurate and reliable is directly related to the correction effect. Moreover, any disease of vision loss can only be diagnosed after the refractive error has been ruled out or corrected.

Therefore, optometry is an important examination tool in the medical field.

Myopia in adolescents is mainly caused by prolonged, close proximity, and improper use of the eyes. Especially when reading and writing, I like to put my eyes very close, the adjustment of the eyeball will be strengthened, and over time, it will cause eye swelling and pain, vision loss, that is, the so-called regulatory spasm, if the pupil is not dilated during refraction, the adjustment of the ciliary muscle can make the lens convex, the refractive power increases, resulting in the deepening of myopia. The error of the refractory power will be very large.

Therefore, if adolescents suffer from myopia, dilated eye refraction is necessary when dispensing glasses. The advantages are: to avoid the juvenile ciliary muscle adjustment too strong, or to loosen the adjustment of spasticity, so that subjective refraction becomes objective refraction, the prescription of refraction is more accurate, and the pseudo-submersion myopia caused by the adjustment of spasm is avoided, and at the same time, it also plays a leading role in pseudomyopia.

For young children who can't mess up the beam due to optometry, they can grasp a reliable objective index after the bridge dilates the large pupils, so that the myopia degree obtained by optometry is more accurate. Some children have normal fundus and refractive interstitial examination, but poor vision, and need to use optometry to rule out refractive error. For more complex refractive errors, such as high power of distant and myopic astigmatism, mixed astigmatism, high myopia, high astigmatism, etc., dilated refraction is more needed.

Patients with poor vision correction or opacity of the refractive interstitium after small pupil refraction should undergo dilated refraction.

When adolescents have vision loss or unstable vision, and suspect whether there is pseudomyopia, they should dilate their pupils to refraction and rule them out.

Condition. First of all.

Children under the age of 16 who are new to spectacle must have their eyes dilated and refraction. Because they are likely to have pseudomyopia, (i.e., tension in the eye muscles due to prolonged close learning, but can return to normal after a period of rest.) If you refraction after dilated pupils, it will make the prescription more accurate.

Secondly. Children with farsightedness should also be refracted before getting glasses. Because children with farsightedness have hidden farsightedness, and a considerable number of them also have amblyopia and strabismus.

It is difficult to understand the true degree of farsightedness without dilated eye examination, and the prescription may be undermatched, which is not enough to correct amblyopia and strabismus.

Dilated refraction effects.

Pupil dilation has a temporal effect on children. In general, slow mydriasis takes longer (about 21 days), but the effect is better. It is the final prescription of the "shadow method" after the eyes of the "troopin".

This method is more suitable for younger children and children with farsightedness and amblyopia. Rapid mydriasis is very rapid (about 1 day). This method is suitable for children in general.

It won't interfere with your child's normal learning, as long as you take two days off. Don't worry if your child has dilated pupils and may feel photophobia and blurred vision. These symptoms are normal and will be fine after a period of rest.

Summary. Fortnight.

If you have fundus disease or refractive error, dilated eye examination is recommended. It is recommended that if there is a refractive error for dilated pupil examination, it is recommended to do it twice a year, if it is because of fundus lesions, the pupils should be dilated to facilitate examination, generally as long as it is determined according to the needs of the condition, usually pay attention to rest, reasonable use of eyes, control the use of mobile phones, computers, TVs and other fine eyes, and exercise more, such as running!!

A few days after the dilation of the pupil, the pupil can be re-dilated.

If you have fundus disease for two weeks, or if you have refractive error, etc., dilated pupil examination is recommended. Zi Ran suggests, if there is a refractive error for dilated pupil examination, it is recommended to do it twice a year, if it is because of fundus lesions, to expand the pupil cherry blossom spike, easy to check, generally as long as it is determined according to the needs of the condition, usually pay attention to rest, reasonable use of eyes, control the use of mobile phones, computers, televisions and other fine eyes, more exercise, spinal books such as running!!

Moxibustion can recover quickly and improve the body's righteousness.
