What term describes a narrow field of side vision?

Tunnel vision is the term that describes a narrow field of side vision. This phenomenon occurs when an individual's peripheral vision is impaired or restricted, leading to a visual field that is limited primarily to what is directly in front of them. This can be a critical concern for drivers, as it reduces awareness of surroundings, such as vehicles, pedestrians, and obstacles that might be present outside the direct line of sight.

Recognizing tunnel vision is important for drivers because it can significantly impact their ability to make safe driving decisions. It is essential for a driver to maintain an adequate field of vision to react appropriately to changing road conditions and avoid potential hazards. Understanding the effects of tunnel vision helps in promoting safe driving practices and awareness of one's visual capabilities on the road.
