Children cannot dilate their pupils. It is optometry when the ciliary muscle of the eye is completely paralyzed by drugs, making it lose its adjustment function. During mydriasis, strong light stimulation, especially strong sunlight stimulation, should be avoided, and a sun hat or sunglasses should be worn outdoors. After stopping mydriasis, the pupil will return to normal in about three weeks, but due to individual differences, the pupil recovery time will be different, which is normal.

Astigmatism is generally a problem of corneal curvature, that is, the problem of dark circles, which can be divided into regular astigmatism and irregular astigmatism. Conventional astigmatism can be treated by mydriatic optometry, glasses or orthokeratology. If you are between 20 and 45 years old, you can also consider surgical treatment; Irregular astigmatism should be further examined for other corneal lesions, such as keratoconus. Therefore, after astigmatism, it is necessary to correct mydriasis and optometry.

Many people can't see clearly because of astigmatism, resulting in blurred vision. Normally, you are nearsighted, and then you will have such symptoms. If you feel that you can't see clearly, you will choose strabismus, but in the process of strabismus, the cornea of the eye will be greatly oppressed.

Over time, the cornea will be uneven, causing all kinds of serious problems. So if you want to solve the problem of astigmatism, you must remember not to squint.
