Amblyopia is a condition in which a child’s visual system does not develop normally during growth and development due to refractive errors (hyperopia, myopia, astigmatism), strabismus and other eye diseases, resulting in a best-corrected visual acuity of less than 0.9. Among children with low visual acuity (less than 1.0), it is important to be aware of the possibility of amblyopia, especially monocular amblyopia, which is often overlooked. It can usually be detected by examination by a pediatric ophthalmologist. The key to amblyopia treatment is early detection and early treatment, usually with better results before the age of 6. The specific method is to take comprehensive measures to address the cause of the disease, including refractive correction (i.e., wearing glasses or contact lenses), healthy eye masking, visual training, strabismus correction (surgery), and restoration of monocular function in both eyes. Once a child is diagnosed with amblyopia, parents should actively work with their child to treat the amblyopia. The first step is to get glasses for the child, which should be worn every day and should never be taken off at times. In addition, various amblyopia training should be carried out under the guidance of a doctor. Such as amblyopia treatment instrument when training, usually let the child do more fine work: wear beads, tracing, etc.. Parents must follow the doctor’s requirements, let the child cooperate with the treatment, do not be afraid of trouble, and affect the training effect, or even training failure.
