  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.
