Abstract
The present invention relates to an electrowetting-based variable-focus lens comprising an enclosure with at least two components, an arrangement of first and second immiscible liquids (5, 6) contained in said enclosure, wherein the liquids have different refractive indices and are in contact over a moveable refractive optical interface, a first electrode associated with one of said liquids, the electrode comprising a film (21, 22; 23, 24) of conducting material extending from a region internal to the enclosure to a region external to the enclosure, wherein the conducting material forms a bonding element between said components of the enclosure.
