(hi-per-o'-pe-ah). That condition of the refractive media of the eye in which, with suspended accommodation, the focus of parallel rays of light is behind the retina; it is due to abnormally short anteroposterior diameter of the e, or to a subnormal refractive power of its media. Absolute, that which cannot be corrected cometely by accommodation, so that there is indistinct ion even for distance. H., Axial, that due to abrmal shortne of the antero-posterior diameter of eye, the refractive power being normal. H., acultative, that which may be corrected by the com mod at i on, so that there is distinct vision at a tance. H., Latent, that part of the total that cant be overcome by the accommodation, or the differce between the manifest and the total hyperopia. H., anifest, that which the accommodation can overrate, or that corrigible by a convex gla aided by e accommodation. H., Relative, a high hyperopia which distinct vision is po ible only when exce ive nvergence is made. H., Total, the entire hyperopia, both latent and manifest.
