A visual field test measures how much ‘side’ vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights or grids are flashed on, and you have to press a button whenever you see them. 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.
Each eye is tested separately and the entire test takes 15-45 minutes. If you only need Dr. Reimer to perform a driving licence visual field test, it may take as little as 5-10 minutes for this eye service.
