Amblyopia in one eye in children may be caused by refractive error, strabismic amblyopia, etc.. It can be corrected by wearing eyeglasses, strabismus surgery and other methods. 1. Wearing glasses: Refractive error may cause amblyopia in one eye, and it is recommended to consult a doctor in time to correct the vision with moderate concave lenses. 2. Strabismus surgery: Strabismus is a condition in which both eyes cannot focus on the target at the same time, i.e., when one eye is focusing on a target, the other eye is not in the same position as the focusing eye. Strabismus surgery is usually performed to restore or improve visual function. If a child has amblyopia in one eye, there may be other causes, and the child should seek medical attention and treatment as prescribed by the doctor.
