Abstract
The disclosed system may include (1) a lens assembly that provides an electronically controllable cylindrical power, oriented along an electronically controllable axis, on an optical path between a display device and an eye of a viewer in response to at least one first control signal, and (2) a controller that (a) receives information indicating a cylindrical power component and a cylindrical axis component of an eyeglass prescription for the viewer, and (b) generates, based on the information, the at least one first control signal to cause the lens assembly to provide the cylindrical power component, oriented along the cylindrical axis component, for the viewer. Various other systems and methods are also disclosed.
