What term describes a reflex direction of the eye toward an object?

• A. Fixation
• B. Accommodation
• C. Pupillary reflex
• D. Vitreous body

Answer: (A)

Fixation is the reflex direction of the eyes toward an object, aligning the target with the fovea so you can hold a steady, sharp gaze on it. When you look at something, the eye movements bring the object into the center of vision, and fixation is the subsequent maintenance of that gaze. This is distinct from accommodation, which is changing the lens to focus at different distances; the pupillary reflex, which adjusts pupil size in response to light or focus; and the vitreous body, which is the gel-like material filling the eye. So the term that describes turning and holding the gaze toward an object is fixation.
