Visual Field Testing

1 C Users Shari Pictures visual field

A visual field test measures how much 'side' vision you have. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.
