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.

Myopia : Myopia: Nearsightedness, the ability to see close objects more clearly than distant objects.
Myopia can be caused by a longer-than-normal eyeball or by any condition that prevents light rays from focusing on the retina.
Most forms of myopia can be managed with corrective lenses. Surgery is available to permanently correct some forms of myopia, although long-term effectiveness and safety has not been fully
determined.
