   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.
