Abstract
Systems and methods for providing an optical system in a head-mounted display (HMD) that is operable to modify virtual image light to correct for one or more vision conditions of a user's eyes. The optical system includes a left optical subsystem for the left eye and a right optical system for the right eye. Each optical subsystem includes at least one correction portion having a diffractive optical element assembly. Selective electrical or mechanical control or adjustment of the diffractive optical element assembly provides for the correction of vision conditions in the user's eyes.
