My*o"pi*a, n. Etym: [NL. See Myope.] (Med.) Defn: 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.
