A pair of multifocal contact lenses, each including an optical zone portion and a stabilization zone portion. The optical zone portion has a distance prescription zone and a near prescription zone. The near prescription zone has a near vision add power appropriate to reduce accommodative effort to substantially zero for a selected working distance and convergence support having base-in prism combined between the pair of multifocal lenses appropriate to reduce convergence effort to substantially zero for the selected working distance. The stabilization zone portion is structured to maintain orientation of the pair of lenses with a base of the base in prism directed substantially nasally.
