An eye disorder in which there is a significant disparity in the refractive power of the two eyes. One eye may be normal, while the other is astigmatic, nearsighted, or farsighted. Therefore, each eye needs a different lens correction from the other. A wrong prescription can induce aniseikonia or anisophoria. Uncorrected anisometropia of large amounts rarely displays symptoms since there is amblyopia, or one of the retinal images is suppressed. Low quantities of uncorrected anisometropia may cause double vision or eyestrain. Congenital abnormalities in the iris anatomy are also responsible for asymmetrical pupil sizes in children.
