1. Augmented reality (AR) glasses comprising:
a first light source configured to emit display light for displaying an augmented reality image;
an eye tracking (ET) sensor configured to detect reflection light reflected from a user's eyes;
a glass member comprising a display waveguide configured to guide the display light emitted from the first light source to a display area of a see-through display and an eye tracking (ET) waveguide configured to guide the reflection light to the eye tracking sensor; and
a processor electrically connected to the first light source and the eye tracking sensor,
wherein the processor is configured to:
control the first light source to emit the display light, and
track a user's gaze, based on the reflection light detected through the eye tracking sensor.
