A vari-focal fluidic lens is provided. The fluidic lens includes a frame, an first membrane, a second membrane, and an optical fluid.

The elastic membrane is attached to one side of the frame to cover at least the lens portion. The second membrane is attached to an opposite side of the frame to cover at least the driving portion and is deformable in response to temperature change to vary a volume of the inner space. Optical fluid is contained in the inner space.
