As the membrane expands, the center thickness of the lens can increase, and accordingly, the optical power of the lens can increase. The reverse also can be achieved by causing the membrane to collapse inward, causing the center thickness to decrease, thereby creating negative optical power (i.e., diverging light rays after passing through the lens).

These can vary from designs that have a non-constant thickness of liquid crystal, often a lens-shaped cavity, whereby the electric field is stronger where the liquid crystal thickness is weaker, creating a focusing gradient. Other lenses can insert various shapes of conductors or insulators into the gap between the substrates to tailor the shape of the electric field established in the liquid crystal cavity.
