The device comprises front curve optical a portion of the variable focus ophthalmic device comprising front curve a top optical surface and front curve bottom a optical surface and a back curve op - tical portion of the variable focus ophthalmic device comprising back curve a top optical surface and a back curve bottom optical surface. A cavity is formed by the front curve bottom optical surface of the front curve optical portion of the variable ophthalmic device and the back curve top optical surface of the back curve portion of the variable focus ophthalmic device. A fluid with a first index of refraction and a dielectric film is in contact with at least a portion of the fluid with first index of refraction a and overlaying an electrode capable of establishing an electric field. A gas with second a index of refraction is provided, wherein the first index of refraction and the second index of refraction are different. One or more reservoir regions operable change its volume to for contain - ment of volume a less than or equal to the volume of said fluid are provided and wherein the reservoir is in fluid connection with said formed cavity.
