Zusammenfassung:	The present invention discloses a translating multifocal contact lens including one or more of multiple Optic Zones, a lower-lid contact surface, and an under-lid support structure and method steps and apparatus for implementing the same. In preferred embodiments, a translating multifocal lens with at least a portion of one surface may be Free-formed comprising one or both of a lower-lid contact surface and an under-lid support structure capable of limiting the amount of translation of a lens across a surface of an eye when an eye changes from one Optic Zone to another.
