#ametrop

• Ametrope — A person suffering from ametropia; having an eye affected by a refractive error (such as myopia, hyperopia, or astigmatism), which prevents the formation of a clear image on the retina without corrective lenses. From a structural perspective, it describes an ocular optical system whose anatomical proportions between the anteroposterior axial length and the convergence power are unbalanced.
• Ametropic — The feminine singular form of the adjective 'ametrop'; describes an entity, optical system, or ocular structure affected by a refractive error. As a common noun, it designates a female patient or individual suffering from a form of ametropia (myopia, hyperopia, astigmatism) who requires correction via convergent, divergent, or cylindrical lenses to achieve proper focus on the retina.
• Ametropia — 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.
