Confrontation testing should be performed at a distance of

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (B)

Confrontation testing checks the peripheral visual fields by presenting a simple stimulus while the patient fixates on a central point. The standard distance of about two feet provides a reliable, comfortable setup where the stimulus is large enough to be seen and easy to monitor, yet far enough away to test a meaningful portion of the peripheral field. This distance helps ensure consistent results across patients and minimizes issues from very near or very far testing. If you move closer than two feet, the stimulus can appear too large or be affected by accommodation, making responses less consistent. If you move farther than two feet, the stimulus becomes smaller and harder to detect, reducing the test’s sensitivity. That’s why two feet is used as the best practical distance.
