a visual impairment resulting from faulty refraction of light rays in the eye. Subtypes include myopia astigmatism and hyperopia.
a refractive error (such as myopia, hyperopia, or astigmatism) in which images fail to focus upon the retina, requiring spectacle lenses or contact lenses to refocus the incoming light onto the retina
The presence of a refractive error in the eye.
Occurs when eyes with vision defects such as astigmatism, myopia, and Hyperopia are unable to properly focus light rays into a clear image. Eyes with ametropia typically require corrective lenses or eye surgery.
(ophthalmology) faulty refraction of light rays in the eye as in astigmatism or myopia
Refractive condition in which parallel rays do not focus on the retina; manifestation if refractive error.

Abnormal refractive eye condition, such as myopia, hyperopia and astigmatism. ( ametropie, n.f)
the refractive condition where parallel rays do not focus on the retina that is, there is an imperfection in the refractive state of the eye.
Any imperfection in refractive state of the eye. Examples would be one with hyperopia, myopia, or astigmatism.
Refractive error that prevents the eye from focusing the image of distant objects on the retina; includes hyperopia, myopia and astigmatism.
The condition of an eye with a refractive error.
