Which visual function provides awareness of objects outside the central field?

• A. Peripheral vision
• B. Eye sight
• C. Depth perception
• D. Glare recovery

Answer: (A)

Peripheral vision is what lets you notice objects at the edges of your visual field without looking directly at them. This broad awareness is crucial when driving, as you can sense hazards, pedestrians, or vehicles coming from the sides while you focus ahead. The other terms don’t describe this edge-detecting function: eye sight refers to how clearly you can see (visual acuity) in your focus area, depth perception is about judging distance, and glare recovery is how quickly vision returns after a bright light. Peripheral vision provides awareness of objects outside the central field, enabling safer scanning and moment-to-moment hazard detection.
