Myopia also called nearsightedness, is a condition in which a person has difficulty seeing objects that are located at a distance, although vision of close objects (near vision) is good. Nearsightedness: Visual image is focused front of the retina. Normal vision occurs when light is focused directly on the retina rather than in front or behind it.   In some cases, nearsightedness is an inherited condition caused by an abnormally long eye, as measured from front to back. Because there is an increased distance between the cornea (the clear window that covers the front of the eye) and the retina (the light-sensitive layer at the back of the eye), images tend to focus in front of the retina, rather than on the retina itself. In other cases, nearsightedness is the result of a mismatch between the length of the eye and the ability of the eyes lens to focus an image in the correct location. Again, this causes images to focus in front of the retina, resulting in nearsightedness.   © 2005-2008 VISIONFOREGOLFING.COM AND TIMED DESIGNS, INC. ALL RIGHTS RESERVED
