PURPOSE: An aspherical electricity variable type fluid lens is provided to control fluid pressure through interaction of a pair of permanent magnets and control focal distance with low power by consuming the power in the variable area only. CONSTITUTION: A first PDMS polymer transparent film and a second PDMS polymer transparent film comprise a transparency liquidity refractive agent. A compression tube is combined with the first PDMS polymer transparent film. A first compression tube rigid frame(103) and a second compression tube rigid frame fix the compression tube and the first PDMS polymer transparent film. A piston frame(101) is combined with the top of the first compression tube rigid frame. A first permanent magnet(100) is combined with the piston frame. The second PDMS transparent film is combined with the center of inside a voice coil frame(109). The voice coil frame is combined with the bottom of the second compression tube rigid frame. A fixing ring fixes the second PDMS transparent film. A voice coil is wound around one side of the voice coil frame. A second permanent magnet(110) is combined with the bottom of the voice coil frame.
