PROBLEM TO BE SOLVED: To provide an optical device in which unintended deformation of an interface is avoided. SOLUTION: The present invention discloses an optical device comprising a container enclosing an insulating liquid (A) and a liquid (B) responsive to an electric field. The insulating liquid (A) and the liquid (B) responsive to an electric field are immiscible and are in contact with each other via an interface (14), and at least one of the liquids (A) and (B) are at least partially placed in a light path through the container. The optical device further comprises: electrode arrangements (2 and 12) for controlling a shape of the interface (14) by means of a voltage; and means (100) for preventing the interface (14) from an exposure to an external electric field. Consequently, the build-up of an electrostatic charge on a surface of the optical device is avoided, which prevents an unwanted distortion of the interface (14) caused by the interaction of the liquid (B) responsive to an electric field and the electrostatic charge.
