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.
