Ametropia
Definition
Any defect or anomaly of eye refraction, characterized by the inability of the ocular optical system (cornea, crystalline lens) to focus parallel light rays exactly on the retina when accommodation is at rest. This structural disruption includes myopia, hyperopia, and astigmatism, being the opposite of the normal state of emmetropia.
