What is meant by the term "field of vision"?

The term "field of vision" refers to the total area that an individual can see without the need to move their head or eyes. This encompasses all the visual information that can be perceived at any given moment and highlights the importance of peripheral vision alongside central vision.

Having a clear understanding of field of vision is essential in many contexts, such as evaluating visual abilities for driving, sports, or various occupational tasks. It indicates how much of the environment is visible to a person at a glance, which is crucial for situational awareness and safety.

The other options focus on more specific aspects of vision, such as restricted fields due to eye coverage or the state of vision with closed eyes, which do not capture the full scope of vision available without additional movement.
