- Kinetic visual field test. In some cases, you may have a test called kinetic visual field testing. While it is similar to the perimetry testing process described above, the kinetic test uses moving light targets instead of blinking lights.

The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; [1] in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.
A visual field test is a simple and painless test an eye care provider gives you to diagnose or monitor various eye conditions. A visual field test measures two things: How far up, down, left and right your eye sees without moving (when you’re looking straight ahead).
Definition. The field of vision is that portion of space in which objects are visible at the same moment during steady fixation of gaze in one direction. The monocular visual field consists of central vision, which includes the inner 30 degrees of vision and central fixation, and the peripheral visual field, which extends 100 degrees laterally ...
