Myopia commonly known as being nearsighted and shortsighted
is a condition of the eye where the light that comes in does not directly focus
on the retina but in front of it. This causes the image that one sees when
looking at a distant object to be out of focus, but in focus when looking at a
close object. Eye care professionals most commonly correct myopia through the
use of corrective lenses, such as glasses or contact lenses. It may also be
corrected by refractive surgery, though there are cases of associated side
effects. The corrective lenses have a negative optical power which compensates
for the excessive positive diopters of the myopic eye.
