Visual fields
Visual fields refer to the entire area that a person can see while looking straight ahead, including peripheral (or side) vision. This area encompasses everything visible, from the far left to the far right, and from above to below. Visual field tests are commonly conducted by eye care professionals to assess an individual’s vision and detect conditions like glaucoma, retinal issues, or neurological disorders. A normal visual field allows a person to perceive their surroundings effectively, which is crucial for daily activities and safety. Any loss or reduction in this field can indicate potential health concerns.

Visual fields refer to the entire area a person can see at any given moment, including both central and peripheral vision. Central vision is what we focus on directly, while peripheral vision allows us to detect motion and objects outside our direct line of sight. Each eye contributes to the overall visual field, which is approximately 180 degrees wide, encompassing what we can see without moving our head. Understanding visual fields is crucial in evaluating eye health and detecting conditions that may affect vision, such as glaucoma or retinal damage.
