Which statement best describes proximal accommodation?

• A. It is stimulated by retinal feedback
• B. It is stimulated by perceptual cues and does not rely on retinal feedback
• C. It occurs only in bright light
• D. It is identical to tonic accommodation

Answer: (B)

Proximal accommodation is driven by perceptual information about how near an object appears, not by the quality of the image on the retina. The brain uses cues from context, size, and our sense of distance (proprioceptive and cognitive cues about proximity) to adjust lens power. This means it can occur based on how near something is, even if retinal feedback (blur signals) isn’t guiding the response. That’s why the statement describing it as being stimulated by perceptual cues and not relying on retinal feedback is the best description. The other ideas imply that retinal blur drives it, or tie it to lighting or to a baseline state, which doesn’t capture this distance-based, top-down cueing.
