Myopia
"Myopia" is an error of refraction of the eye in which near objects can
be seen clearly while those in the distance appear blurred. This condition
is commonly called "nearsightedness," and is caused by the eye being too
long from front to back. As a result, the corneal lens focuses images of
distant objects in front of the retina. Glasses or contact lenses with
concave lenses will correct the eye's error and bring the images of
far-off objects into sharp focus on the retina. Concave lenses curve
inward, like the inside of a bowl.
