An electrowetting optical device having a non-aqueous conductive liquid and a non-conductive liquid, the liquids being non-miscible, and a dielectric enclosure on which both liquids are in contact and form a triple interface. The non-aqueous conductive liquid includes a non-ionic polar organic solvent, and at least 2 weight % of a first compound, where the first compound is non-aqueous and is either ionic or non-ionic. If the first compound is non-ionic, the first compound is more polar than the solvent, the polarity of the non-ionic first compound being measured by Hansen parameters, a sum of the Hansen parameter for polarity (&#x3b4;) and of the Hansen parameter for hydrogen bonding (&#x3b4;) being higher than the sum of the corresponding Hansen parameters of the non-ionic polar organic solvent, and the non-aqueous conductive liquid having an ionic second compound.

Non-aqueous conductive liquids for liquid lenses

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&#xb0; C.
