A child with 400 diopters of myopia and 100 diopters of astigmatism in the right eye is more serious. Myopia of 400 diopters is considered moderate myopia and astigmatism of 100 diopters is considered mild astigmatism, both of which can lead to discomfort such as unclear vision at long distances and easy fatigue of the eyes. If the child’s eyeballs continue to grow as the body develops, the amount of myopia and astigmatism may continue to increase. If this growth is not prevented and controlled in time, and the myopia and astigmatism grow to a high level, more serious complications may occur, such as peripheral retinal degeneration, retinal tears, or even retinal detachment and other serious blinding eye diseases. It is recommended that children wear glasses strictly, pay attention to eye habits, participate in outdoor activities, and visit the hospital every 3-6 months to follow up changes in vision.
