Anisometropia (/ænˌaɪsəmɨˈtroʊpiə/ US dict: an·ī′·sə·mə·trō′·pē·ə) is the condition in which the two eyes have unequal refractive power; that is are in different states of myopia (nearsightedness) hyperopia (farsightedness) or in the extreme antimetropia (wherein one eye is myopic and the other is hyperopic) the unequal refractive states cause unequal rotations thus leading to diplopia and asthenopia.
