Visual Field Test
A Visual Field Test is just a more comprehensive screening of your full horizontal and vertical vision than what is done prior to your yearly exam. It helps determine the potential of blind spots (scotomas), which could indicate eye diseases.
Using a formal visual field testing machine, the patient will be asked to press a button, similar to the screening, when a flash of light is seen. Each eye is tested individually and usually takes around 3–4 minutes to complete.
