How does speed affect peripheral vision?

Speed has a significant influence on peripheral vision, particularly in driving scenarios. As a driver’s speed increases, the ability to perceive objects and movements outside of one’s direct line of sight diminishes. This narrowing of peripheral vision occurs because the brain focuses more on the area directly in front for immediate navigation and hazard detection, which makes it harder to notice things happening at the sides.

At higher speeds, the need to concentrate on the road ahead becomes more critical, and distractions or movements in the periphery can go unnoticed. This reduction in awareness of side objects can lead to unsafe driving practices, such as missing important visual cues related to other vehicles, pedestrians, or potential hazards. Understanding the impact of speed on peripheral vision is essential for safe driving, as it emphasizes the importance of adjusting speed to maintain broader situational awareness and reaction time.
