determining a position and an orientation of a head-mounted display (HMD) worn by a user, the HMD including an electronic display, a front optical element, and a back optical element that is between the front optical element and the electronic display;
determining a portion of a virtual scene based on the determined position and orientation of the HMD;
displaying the determined portion of the virtual scene being on the electronic display of the HMD;
determining an eye position for each eye of the user using an eye tracking module;
determining a vergence depth based on an estimated intersection of gaze lines corresponding to the determined eye position for each eye; and
adjusting an optical power of the HMD based on the determined vergence depth by simultaneously adjusting a position of the back optical element with respect to the electronic display at a first rate of adjustment and adjusting a position of the front optical element with respect to the electronic display with the back optical element between the front optical element and the electronic display at a second rate of adjustment that is a same as the first rate of adjustment to vary an adjustable distance between the back optical element and the front optical element in accordance with the vergence depth.
