What eye function is the nurse preparing to assess when the client is asked to stand 20 feet from a specific chart that is mounted on the examination room wall?

A. External Eye Structures: This assessment involves examining the visible parts of the eye and surrounding structures, not the distance vision. B. Near Vision: Near vision is typically assessed using a reading chart held at a close distance, not a chart mounted on the wall. C. Peripheral Vision: Peripheral vision assessments involve testing the field of vision to detect loss or abnormalities, rather than focusing on distant vision. D. Distant Vision: Standing 20 feet from a chart to read letters tests distant vision, as it assesses the ability to see objects clearly at a distance.
