The area of the external environment that is visible to the eye or eyes at a given position; the field of vision. Visual field is usually measured in degrees of visual angle.

Space visible to the eyes when they are fixating straight ahead.

Total field of vision that can be seen by both eyes without turning the head.

Field of vision measured by special tests.

Field of vision as tested by computer aided techniques

all of the points of the physical environment that can be perceived by a stable eye at a given moment

The area of vision to the side when one is looking straight ahead. Defects in the sensitivity of the peripheral vision can be helpful in diagnosing many types of visual and general health conditions.

The portion of the environment that the eye sees on fixed forward gaze.

The area that one can see without moving one's eyes.

the region in space which can be seen without shifting the gaze; can apply to that of both eyes or of each eye separately

Refers to the area in which objects are visible to the eye without a shift in gaze. This normally extends in an arc of 150 degrees from right to left and 120 degrees up and down.

The field of view that can be perceived when the head and eyes are kept fixed.

VIZ-yoo-ul FE-eld] The complete area of vision that includes what is seen above, below, to the sides and in the center.

the entire area that can be seen while the eye is fixing or gazing steadily at a target in the direct line of vision

the area on both sides that can be seen while looking straight ahead

Area of vision the eye can see while its attention is directed straight ahead. Go to Top

The entire area that can be seen when the eye is forward, including peripheral vision.

The entire range in which a person can see, including peripheral vision.

the entire expanse of space visible at a given instant without moving the eyes - also called field of vision

(field of vision, vision field): Area around the zone of central vision. ( champ visuel, n.m)

Test of the range of vision side to side, up to down

The entire area that can be seen when your eye is looking forward, including any side vision.

Portion of space extending in all directions which can be seen by one eye without changing its position.

the area or extent of space visible to an eye in a given position of gaze. There is a central visual field--that is directly in front of us, the target at which we are looking, and a peripheral visual field---that which we perceive in our "side vision". The fields of each eye partly overlap. We do not perceive the blind spots from each eye because the area that is missing in one eye is present in the other.

The space in which objects are visible to an eye when the eye is in a fixed position. Visual field, which tends to diminish with age, approximates a monocular field of 60¡ nasally, 94¡ temporally, 54¡ up and 70¡ down.

(VIZ-yoo-ul FEELD) Extent of area visible to an eye as it looks straight ahead. Measured in degrees away from direct line of sight.

The total visual array acting on the eye when it is directed toward a fixation point.

The term visual field is sometimes used as a synonym to field of view, though they do not designate the same thing. The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments" (J. Smythies http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=8804101&dopt=Abstract), while field of view "refers to the physical objects and light sources in the external world that impinge the retina".
