Abstract
Head-mounted display systems may include a display subsystem, an optics subsystem, a prescription accommodation subsystem, and a varifocal adjustment subsystem. The prescription accommodation subsystem may include a prescription accommodation actuator that is configured to adjust a focus of a displayed image to account for the user's visual refractive error. The varifocal adjustment subsystem may include a varifocal adjustment actuator configured to further adjust the focus of the image to change a perceived view of the image on the display subsystem. Various other methods, systems, and computer-readable media are also disclosed.
