A visual field test is a method of measuring an individual's entire scope of vision, that is their central and peripheral (side) vision.

Visual field testing maps the visual fields of each eye individually and can detect blind spots (scotomas) as well as more subtle areas of dim vision.

The visual field test is a subjective examination, so the patient must be able to understand the testing instructions, fully cooperate, and complete the entire visual test in order to provide useful information.
