A variable focus lens (10) comprises a fluid chamber (12) having an optical axis (20). One or more piezoelectric element (22) is disposed about the optical axis within a portion of the fluid chamber. First and second fluids (24,26) are disposed within another portion the fluid chamber and in contact with one another over a meniscus (28,36) extending transverse the optical axis, the first and second fluids being substantially immiscible and having different indices of refraction. The perimeter of the meniscus is fixedly located on a surface in relationship to the one or more piezoelectric element, wherein responsive to application of a voltage potential (32) to the one or more piezoelectric element, the one or more piezoelectric element controllably alters one or more of (i) a shape of the meniscus or (ii) a translation of the meniscus.
