Which movements involve both eyes moving in the same direction?

• A. One eye moves
• B. Disconjugate movements
• C. Both eyes move in opposite directions
• D. Both eyes move in the same direction

Answer: (D)

Conjugate movements are when both eyes move in the same direction. When you shift your gaze to the right, left, up, or down, each eye travels in harmony to point toward the same target, using coordinated, symmetrical muscle activity. This is the kind of movement that keeps the two eyes aligned to form a single image as you move your head or track a moving object.

This contrasts with disconjugate movements, where the eyes move in opposite directions to adjust focus between near and far objects. A classic example is convergence, where the eyes turn inward together to look at something close, or divergence, where they move apart to look at something farther away. Movements where only one eye moves (monocular movements) aren’t the coordinated binocular gaze the question is describing.

So the option that states both eyes move in the same direction best captures the concept of conjugate (version) movements.
