ABSTRACT:
Hydrogen-plasma modification of a contact lens made from a fluorinated polymer reduces the surface chemistry of by removing fluorine, leaving behind a carbon-enriched surface that is further plasma processed into a hydrophilic surface for a lens material to be inserted into the ocular environment.
