Which axis corresponds to horizontal gaze shifts (abduction/adduction)?

Explanation:
Horizontal gaze shifts are the left–right movements of the eyes, known as abduction and adduction. In the coordinate framework often used for ocular motility, the axis that runs side to side across the face corresponds to these horizontal movements. This is why abduction (moving the eye away from the midline) and adduction (moving toward the midline) are described as occurring along the X axis. The vertical axis handles up–down movements (elevation/depression), the depth axis handles forward–backward changes (vergence), and any additional W axis isn’t part of the standard horizontal gaze description.
