  Myopia  \My*o"pi*a\,  n.  [NL.  See  {Myope}.]  (Med.) 
  Nearsightedness;  shortsightedness;  a  condition  of  the  eye  in 
  which  the  rays  from  distant  object  are  brought  to  a  focus 
  before  they  reach  the  retina,  and  hence  form  an  indistinct 
  image;  while  the  rays  from  very  near  objects  are  normally 
  converged  so  as  to  produce  a  distinct  image.  It  is  corrected 
  by  the  use  of  a  concave  lens.
