How long should your child wear glasses for astigmatism

Children's astigmatism is mainly due to the refractive state or refractive degree of the eyeball on different meridians, especially the radius of curvature of the corneal surface, R is not a spherical surface, and the eye is not adjusted in a state, the parallel rays five meters away through the different meridians of the eyeball, can not form a focal point on the omentum, so the image formed on the retina is blurred, this refractive state is called reflection.

Then for low-speed and low-degree astigmatism, it will not have a too obvious impact on children's learning and life, and it will not affect their ability to see things, so this situation can be observed temporarily. For medium-to-high astigmatism, it is recommended that you must wear glasses for a long time, and it is recommended to perform a proper and correct dilated eye refraction before fitting glasses, and then wear them.

Pseudoastigmatism symptoms

Generally speaking, if you wear glasses for correction, these symptoms tend to disappear obviously, and in normal times, you must also pay attention to developing a good eye habit and eye hygiene, do not overuse your eyes for a long time, and do not stay up late often. Because generally speaking, if you don't pay attention to your eyes, the degree of astigmatism increases relatively quickly, and in normal times, you must pay attention to looking into the distance every half an hour. If you have these symptoms, you must first go to the hospital for dilated eye refraction to see the specific power of astigmatism, and then you can wear a suitable pair of glasses according to this power. I know that astigmatism is often caused by irregular corneal surfaces, and the direct symptoms of astigmatism are blurred vision, and many people will have a feeling of double vision or dizziness.

Is it possible for astigmatism to return to normal?

That is to say, in the process of the baby's gradual development, the astigmatism is constantly changing, and it is possible that there is astigmatism in the early stage, and after a slow change, the astigmatism will gradually disappear. That's why we ask that babies be rechecked every six months to see how their prescription changes if astigmatism is detected.Astigmatism of the human eye is mainly determined by the astigmatism of the cornea, and the cornea of the baby is a transverse ellipsoidal shape, and with the growth of age, this horizontal ellipsoid shape will gradually develop in the direction of the vertical ellipsoid. In infancy, astigmatism may be negative hyperopic astigmatism, slowly become simple hyperopic astigmatism, slowly become mixed astigmatism, and then from simple myopic astigmatism, to finally compound myopic astigmatism.
