Hypermetropia \Hy`per*me*tro"pi*a\, Hypermetropy
\Hy`per*met"ro*py\, n. [NL. hypermetropia, fr. Gr. ? excessive +
   ?, ?, the eye. See {Hypermeter}.]
   A 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; farsightedness; -- called
   also {hyperopia}. Cf. {Emmetropia}.

   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.
