Which functional domains are often measured in VR outcomes?

• A. Reading, driving, and cooking
• B. Vision acuity only
• C. Color perception
• D. Hearing thresholds

Answer: (A)

The idea being tested is that VR outcomes in vision rehabilitation are about how well someone can perform real-world tasks, not just clinical vision tests. Reading, driving, and cooking are classic examples because they require a blend of vision with attention, processing speed, and motor skills. VR can simulate these activities and measure meaningful performance—how quickly a task is completed, how accurately it’s done, and whether safety is maintained. This provides a direct window into daily independence and how rehabilitation is helping.

Reading assesses sustained, fine-use of vision in a familiar task; driving tests scanning, speed of visual processing, and hazard perception in a dynamic environment; cooking evaluates planning, sequencing, and the ability to monitor visually guided steps in a practical home task. Together they cover a broad range of everyday functional demands, making them well-suited as VR outcome domains.

The other options focus on isolated or non-visual measures—acuity is a basic eye-chart metric, color perception is a specific perceptual ability, and hearing thresholds pertain to audition. While important, they don’t capture how vision loss translates into daily activities, which is the purpose of VR outcome measures.
