Hyperopia

(hi-per-o1 ’-pe-ah) \y~kp, over; hip, sight]. 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 an abnormally short anteroposterior diameter of the eye, or to a subnormal refractive power of its media. H., Absolute, that which cannot be corrected completely by accommodation, so that there is indistinct vision even for distance. H., Axial, that due to abnormal shortne of the anteroposterior diameter of the eye, the refractive power being normal. H., Facultative, that which may be corrected by the accommodation, so that there is distinct vision at a distance. H., Latent, that part of the total H. that cannot be overcome by the accommodation, or the difference between the manifest and the total hyperopia. H., Manifest, that which the accommodation can overcome, or that corrigible by a convex gla aided by the accommodation. H., Relative, a high hyperopia in which distinct vision is po ible only when exce ive convergence is made. H., Total, the entire hyperopia, both latent and manifest. 322
