This invention discloses an optical lens device comprising: a
liquid crystal material housed between two half-
cell components; wherein one or more of the two half-
cell components include a first
concentric electrode pattern and a second
concentric electrode pattern, the first
concentric electrode pattern and the second concentric
electrode pattern being electrically operable in parallel to at least switch the
liquid crystal material to a first state and switch out of the first state; wherein the first state includes a cooperative
refractive index distribution in adjacent first and second regions centered on an
optical axis; wherein at least one of the two half-
cell components includes at least one annular
solid wall structure located in a reset region between a first edge of the first region and a second edge of the second region; and wherein the
solid wall structure is positioned closer to the first region than to the second region; and when the
liquid crystal material is in the first state, the
refractive index of unpolarized light propagating in a direction perpendicular to the half-cell components is more closely matched with the liquid
crystal material at the first edge of the first region than the liquid
crystal material at the second edge of the second region.
