A liquid lens device includes: first and second immiscible fluids defining an interface moveable by electrowetting; a cap portion; a base portion; a gasket positioned between the cap portion and the base portion; an upper window positioned within the cap portion; and a lower window positioned within the base portion, the windows facing and substantially parallel to each other. The lower window comprises opposing primary surfaces and an edge. The lower window is joined to the base portion with an adhesive, the adhesive positioned in contact with a portion of one or more of the primary surfaces and the edge. The fluids are sealed within the cap portion, base portion, gasket and windows. Further, a height of the edge of the lower window is greater than 0.3 mm and less than 1.2 mm.
