The ability to maintain both eyes pointed at precisely the same object is called what?

• A. Binocular fusion
• B. Eye teaming
• C. Saccadic movements
• D. Vergence

Answer: (B)

Two-eyed coordination is needed to keep both eyes aimed at the same object. This ability to work the eyes together so that they fixate on a single target is called eye teaming. When the eyes team well, images fall on corresponding retinal areas and binocular vision is stable, which supports clear depth perception and comfortable viewing. Saccadic movements are rapid eye jumps to new targets, not about keeping both eyes aligned on one object. Vergence describes movements that adjust the angle between the eyes when changing focus distance (convergence for near, divergence for far), which helps align the eyes but is specifically about changing fixation rather than maintaining steady alignment on a single object. Binocular fusion is the brain’s process of combining two slightly different images into one perception, which depends on proper alignment but is about integration after alignment, not the act of maintaining fixation itself.
