Hyperopia \Hy`per*o"pi*a\ (h[imac]`p[~e]r*[=o]"p[i^]*[.a]), n.
   [NL., fr. Gr. "ype`r over + 'w`ps, 'wpo`s, the eye.]
   An abnormal condition of the eye in which, through shortness
   of the eyeball or fault of the refractive media, the rays of
   light come to a focus behind the retina, making vision for
   distant objects better than for near objects; farsightedness;
   -- called also hypermetropia. Cf. Emmetropia. --
   Hy`per*op"tic, a.

   Syn: hypermetropia, farsightedness, longsightedness.

\Hy`per*met"ro*py\, n. [NL. hypermetropia, fr. Gr. ? excessive +
   ?, ?, the eye. See Hypermeter.]
   An abnormal condition of the eye in which, through shortness
   of the eyeball or fault of the refractive media, the rays of

   [Obsolescent]

   Syn: hyperopia, farsightedness, longsightedness.
        [1913 Webster]

   Note: In hypermetropia, vision for distant objects, although
         not better absolutely, is better than that for near
         objects, and hence, the individual is said to be
         farsighted. It is corrected by the use of convex
         glasses. -- Hy`per*me*trop"ic, a.
         [1913 Webster]
