Amblyopia can be corrected. There are three main methods of correction for amblyopia: first, symptomatic treatment. The cause of amblyopia is mainly due to the presence of a variety of congenital diseases in the child’s eyes, such as common monocular strabismus, large refractive error, refractive aberration, congenital cataract, congenital corneal clouding, etc.. The above causes need to be treated symptomatically to get rid of the unfavorable factors. Strabismus can be corrected surgically, refractive error and refractive aberration can be treated with glasses, and congenital cataract and corneal clouding can also be treated surgically. Second, masking treatment. Blocking the healthy eye and forcing the amblyopic eye to gaze can improve the visual acuity of the amblyopic eye. Third, amblyopia training. There are more methods in this category, including the commonly used visual function training, wearing beads, red filters, etc. The appropriate program needs to be chosen according to the child’s condition.
