Astigmatism in children can be corrected by wearing the right prescription eyeglasses. Astigmatism is due to the refraction of incident light through the cornea and lens, can not form a single focal point, so can not form a clear image on the retina. Generally speaking, astigmatism below 100 degrees does not affect vision, it can be left alone for the time being, if it is greater than 100 degrees, especially greater than 200 degrees of astigmatism, which affects normal vision, then you need to wear glasses to correct it. Since children are still young and their bodies are still developing, timely intervention can improve the prognosis and prevent astigmatism from affecting their vision development in the future. If a child has astigmatism, it is recommended that he or she seek medical attention and wear the appropriate lenses to correct it under the guidance of a medical professional.
