Abstract: Introduced herein are various techniques for displaying virtual and augmented reality content via a head-mounted display (HMD). The techniques can be used to improve the effectiveness of the HMD, as well as the general experience and comfort of users of the HMD.

These techniques allow the user to more easily fuse the digital content, thereby decreasing the eye fatigue and strain typically experienced when viewing virtual or augmented reality content.
