Natural Touch Opaque contact lenses are made to alter the color of dark eyes. CooperVision designed Natural Touch Opaque lenses to be worn for up to one year and replaced.
Natural Touch soft contact lenses are made by incorporating opaque pigment in an iris pattern between two layers of tefilcon polymer. The opaquing pigment consists of carmine, mica, and titanium dioxide.
