How to match the right optical lens for children?

Under normal circumstances, when we look into the distance, the distant objects are imaged on the retina of our eyes, so that we can see the distant objects clearly; but for a myopic person, when he looks into the distance, the image of the distant objects is in front of the retina, It's a blurry image in the fundus, so he can't see distant objects clearly.The causes of myopia, in addition to congenital genetic factors (both parents are highly myopic) and abnormalities in the development of fetal eyeballs, the most important reason today is the impact of the environment.

If the child has no myopia and the degree of astigmatism is less than 75 degrees, usually the child's vision is fine; if the astigmatism is greater than or equal to 100 degrees, even if the child's vision is not problematic, some children will also show obvious symptoms of visual fatigue, such as headaches, concentration problems, etc. Not concentrating, dozing off when studying, etc.
After wearing astigmatism glasses, although some children's eyesight did not improve significantly, the symptoms of visual fatigue were immediately relieved. Therefore, if the child has astigmatism greater than or equal to 100 degrees, no matter how far-sighted or far-sighted the child is, we recommend always wearing glasses.
If infants and young children have high astigmatism, it is usually caused by eyeball dysplasia. They should be checked early and get glasses in time, otherwise they will easily develop amblyopia.
