Abstract

The disclosed method may include (1) providing, from a display, an image to an eye by way of a lens assembly on an optical path between the display and the eye, wherein the lens assembly includes (a) a first liquid crystal lens providing a first electronically controllable cylindrical power, oriented along a first constant axis, in response to a first signal and (b) a second liquid crystal lens providing a second electronically controllable cylindrical power, oriented along a second constant axis that is rotationally offset from the first constant axis, in response to a second signal, (2) determining, based on information indicating cylindrical power and cylindrical axis components, the electronically controllable cylindrical powers that result in providing the cylindrical power component, oriented along the cylindrical axis component, and (3) generating, based on the electronically controllable cylindrical powers, the signals. Various other systems and methods are also disclosed.
