of the cornea
. Result of wearing contact lenses improperly or for too long. This is physical warping, and can be seen with the naked eye. The cornea is, for the most part, a smooth curved
surface, however, when contact lenses are overworn (causing hypoxia
), a side effect includes the warping of the cornea, through corneal edema
(warping of the corneal tissue). This changes the shape of the cornea, and affects vision.
If you're in a gutsy mood, go look for pictures of corneal warpage and refractive error changes. They are NOT pretty.
