How is peripheral vision defined?

Peripheral vision is defined as the awareness of what is surrounding us. This type of vision allows individuals to detect movements and objects outside their direct line of sight, which is crucial for spatial awareness and navigating environments safely. Peripheral vision is fundamental for activities such as driving, where being aware of vehicles and pedestrians approaching from the side is important for safety. It serves as a visual cue that complements central vision, helping to form a complete visual field.

In contrast, the other options focus on specific aspects of vision that do not encompass the broader concept of peripheral vision. The ability to see things directly in front pertains to central vision rather than peripheral awareness. Clarity of vision at a distance also relates primarily to central vision, often measured by visual acuity, which is not relevant to peripheral awareness. The perception of colors is tied to color vision and does not adequately define peripheral vision, as color perception occurs primarily in the central field of vision.
