This procedure maps out your field of view and shows your blindspot and any other areas of reduced vision. The test is done individually for each eye. This is useful to the optometrist as it can show up areas that may be less sensitive than others where vision is not so good. It can also be useful in backing up any problems that may have been detected by the optometrist.
The image above is an example of a typical visual fields plot which is printed at the end of the visual fields test. The small dark spots represent the blind spot of each eye – where the optic nerve meets the retina. The central area shows where visual acuity is greatest.
The visual field map on the far left of the image shows an example of a field defect affecting one eye in particular The defects are shown as the darker areas and here vision will be poorer than in the lighter areas.
