Visual Field
|
The entire area that the eye can see from side to side without physically moving the eyes or head (includes peripheral vision). The portion of the environment that the eye sees, on fixed forward gaze, includes the entire field of vision (central and peripheral) and is measured by a perimetry test. The normal field of vision is about 140 degrees for each eye (monocular vision) and about 180 degrees for both eyes (binocular vision). |
