Medically termed nearsightedness or
myopia is a common cause of blurred vision that can be mild, moderate,
or severe. It is a type of refractive error of the eye. If you are
nearsighted, you have trouble seeing things that are far away and out of
focus. This occurs when the physical length of the eye is greater than
the optical length which is difficult for the eyes to focus light
directly on the retina. If the light rays are not clearly focused on the
retina, the images you see may be blurry.
Nearsightedness can impinge on males and
females in the same way. People who have a family history of
nearsightedness are more likely to develop it. Most nearsightedness is
caused by a natural change in the cornea or the lens of the eye.
