anisometropia

A condition in which the refractive error of one eye differs significantly from the other, usually by one diopter or more. This imbalance can cause unequal focus between the eyes, leading to blurred vision, eyestrain, and headaches. Anisometropia may involve myopia, hyperopia, or astigmatism. If left untreated in children, it can result in amblyopia. Treatment options include corrective lenses, contact lenses, or refractive surgery, depending on the severity and type of anisometropia.
