field of vision

Field of vision refers to the entire area you can see when looking straight ahead without moving your eyes or head. It includes both what’s directly in front of you and what you can perceive to the sides, up, and down. Think of it like a panoramic window of your sight—some parts are clearer and more detailed, especially directly in front, while the edges are broader but less sharp. Factors like eye health, lighting, and obstructions can affect your field of vision. Understanding it helps assess visual health and detect issues like tunnel vision or peripheral vision loss.
