Farsightedness
means that you can see things far away better than you can
see things up close when you are not wearing glasses or contacts.
One cause of farsightedness is a cornea (clear front window
of the eye) that is not curved enough. The "flat"
curvature of the cornea causes images to come into focus behind
the retina instead of on the retina. At the retina, the image
is unfocussed and appears blurred. Glasses or contacts help
to overcome the limitations of the flat cornea, allowing images
to focus more precisely on the retina. This results in clearer
vision. LASIK Laser Vision Correction changes the shape of
the cornea itself, allowing images to focus more precisely
on the retina, even without glasses or contacts.
