Abstract
Embodiments generally relate to methods for preventing the formation of an emulsion in a liquid lens. In one embodiment, the method comprises fabricating a top substrate, a bottom substrate, and a central substrate including a cavity configured to be filled by first and second liquids. The liquid lens comprising the top substrate, the bottom substrate and the central substrate is assembled, with at least one of the top substrate and the bottom substrate in the assembled liquid lens being characterized by a stabilizing feature determining that in response to an impact load on the assembled liquid lens that would cause localized pressure drops of maximum magnitude X in the absence of the stabilizing feature, the maximum magnitude of localized pressure drops within the liquid lens is smaller than X.
