Amblyopia is a common eye disease that seriously affects the development of visual function in children, and there are various causes of amblyopia, the most common of which is refractive error. Refractive error, refractive error, strabismus, visual deprivation, and other factors affect children during the process of binocular vision development, which can easily cause amblyopia. Refractive error is one of the common causes of amblyopia, and comprehensive treatment of refractive error amblyopia requires adequate dilated eye examinations and corrective eyeglasses of the appropriate prescription to provide clear images of the retina. The efficacy of amblyopia treatment depends on the degree of amblyopia, the course of treatment, the nature of gaze, and the age of the patient. The younger the degree of amblyopia, the better the outcome; the earlier the treatment of amblyopia, the better the outcome; central gaze is more effective than paracentral gaze; refractive error is the best outcome for all types of amblyopia. Since the age of visual development is before 12 years old, it is important to correct refractive errors and other conditions that cause low vision in children. To avoid the formation of amblyopia.
