1. An augmented reality (AR) device comprising:
a plurality of eye trackers;
a first variable focus lens and a second variable focus lens;
a waveguide disposed between the first variable focus lens and the second variable focus lens;
a display module configured to output light of a virtual image toward the waveguide; and
one or more processors configured to:
obtain, through the plurality of eye trackers, a direction of a left eye of a user of the AR device and a direction of a right eye of the user,
determine a first focus adjustment region of the first variable focus lens based on the direction of the left eye or the direction of the right eye,
obtain a gaze point based on the direction of the left eye and the direction of the right eye,
determine a refractive power of the first focus adjustment region based on the gaze point, and,
