Abstract
Systems and methods include receiving an image for presenting on a display screen of a head mounted display (HMD). The image is provided by an application. The received image is pre-distorted to enable optics provided in a HMD to render the image. An alignment offset is identified for an eye of a user wearing the HMD by determining a position of the eye relative to an optical axis of at least one lens of the optics of the HMD. The pre-distorted image provided by the application is adjusted to define a corrected pre-distorted image that accounts for the alignment offset. The corrected pre-distorted image is forwarded to the display screen of the HMD for rendering, such that the image presented through the optics of the HMD removes aberrations caused by the alignment offset.
