Which condition is characterized by difficulty seeing objects clearly to the side?

Tunnel vision is a condition in which a person's peripheral vision is severely restricted, making it difficult to see objects clearly outside of their direct line of sight. This narrowing of the visual field can lead to challenges in noticing things to the side, which is critical for safe driving and navigation. Individuals with tunnel vision may see objects straight ahead clearly but struggle to perceive those on the periphery, increasing the risk of accidents, especially in situations that require quick reactions to surrounding vehicles, pedestrians, or hazards.

The other options refer to different aspects of vision. "Field of vision" pertains to the entire range of sight that a person can see at one time, which does not specifically indicate restricted peripheral vision like tunnel vision does. "Glare resistance" refers to the ability to see in bright light or when there is a glare, and it doesn't pertain to the clarity of side vision. "Depth perception" involves the ability to judge distances between objects and is more related to how well an individual can perceive spatial relationships rather than side visibility.
