VR visual acuity is usually performed at what distance?

• A. 5 Feet
• B. 7 Feet
• C. 15 Feet
• D. 10 Feet/3 Meters

Answer: (D)

Measuring VR visual acuity at 10 feet (3 meters) targets a functional distance where many daily activities and environmental cues are encountered. This intermediate distance provides a reliable, practical estimate of how well someone can recognize objects, signs, and hazards in typical living or clinical spaces, without forcing excessive accommodation or vergence that can distort far- or near-only testing. It also aligns with standard charts used in rehabilitation settings, making the results more comparable and useful for planning therapy and assistive strategies. Distances like 5 or 7 feet are more focused on near-task performance and can overemphasize near vision, while 15 feet is less representative of everyday spaces in which many tasks occur.
