Which statement describes reflex accommodation?

• A. Vergence accommodation
• B. Reflex accommodation is the most important component of accommodation and automatic focusing due to blur detection; relies on optical feedback
• C. Proximal accommodation
• D. Tonic accommodation

Answer: (B)

Reflex accommodation is the automatic focusing response driven by retinal blur. When the image on the retina is blurred, signals trigger the lens to change power (via the ciliary muscle) to bring objects into sharp focus. This process relies on optical feedback from the visual system and happens without conscious control, making it the dominant automatic mechanism for focusing across different viewing distances. Other components—proximal accommodation (influenced by the perceived closeness of an object) and tonic accommodation (the baseline resting level of focus)—are separate influences, while any concept of “verge nce accommodation” isn’t the standard description of reflex accommodation.
