An electrowetting optical device including a conductive liquid and a non-conductive liquid, the liquids being non miscible, and a dielectric enclosure on which both fluids are in contact and form a triple interface. The non-conductive liquid includes from 0.0001 weight percent to 1 about weight percent of a surface adsorbing agent. The surface adsorbing agent is an amphiphilic molecule having a solubility in water lower than 0.1 about weight percent at 25° C.
