A variable focal length lens in which pressurized fluid is contained within a one-piece flexible membrane. Changes in the pressure on the fluid affect changes in the focal length of the lens, and changes in the cross section of the membrane affect changes in the curvature of the lens. Further, selection of a fluid with an index of refraction different from the index of refraction of the membrane adjust for chromatic variation.
