what is a field test at the eye doctors
In addition to what can be seen straight ahead, the visual field includes what can be seen above, below, and to either side of the point the eyes are focused on. Vision is typically the sharpest in the middle of the visual field. A visual field test is often given as part of an eye exam. Visual field testing helps your doctor to determine where your side vision (peripheral vision) begins and ends and how well you can see objects in your peripheral vision.
