A variable focus lens apparatus includes at least one rigid optical disc, at least one flexible optical membrane and at least one layer of a transparent fluid that is in communication with a fluid channel and a reservoir. When incorporated in a spectacle lens, the lens system enables wearers to adjust the power of each lens individually, so as to achieve the preferred binocular visual performance, consistent with maximum stereopsis and binocular fusion at any desired object plane.
