Contact lenses are provided for the iontophoretic therapies of eyes. Implement to include a reservoir, it is suitable for the therapeutic compound comprising an electrification, the therapeutic combination that an eyeball is electrification that delivers into for influencing the therapeutic combination of electrification provides a current source of iontophoretic current, and a sensing circuit, control current source maintain pH ranges selected by the one of the therapeutic combination of electrification. Alternate embodiment include it is active, the consumption electrode for generating the ion for being enough to provide the electronic repulsive force of the compound of electrification to effect transports into ocular tissue.
