What is the term for the area in space that the eye can see?

Depth of Field
Visual Field
Field of Vision
Scope of Sight

The correct answer is: Visual Field

The term for the area in space that the eye can see is known as the Visual Field. This refers to the entire area that can be seen at any one time with the eyes in a fixed position. It includes both central and peripheral vision. Understanding the visual field is crucial in optometry as it helps assess various eye conditions and overall visual health. Depth of Field pertains to photography and optics, describing how much of the scene appears sharp in an image. Field of Vision is sometimes used interchangeably with Visual Field, but it is less common in clinical settings. Scope of Sight is not a standard term used in the field and might create confusion.
