  \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

  come  to  a  focus  behind  the  retina;  farsightedness;  --  called

  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.
