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. |
