     [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.

  Hypermetropia \Hy`per*me*tro"pi*a\, Hypermetropy
  \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
     light come to a focus behind the retina, making vision for
     distant objects better than for near objects; farsightedness;
     -- now most commonly called {hyperopia}. Cf. {Emmetropia}.
     [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.

     A visual impairment resulting from faulty refraction of light
     rays in the eye. Subtypes include {myopia} {astigmatism} and
