The present invention discloses a visual field examination device and detection method. The device includes: a virtual reality eye mask, electrodes, a visor, and an upper computer； the visor is located inside the virtual reality eye mask, for detecting one eye or both eyes； the electrodes are used for acquiring brain waves of a human body； the virtual reality eye mask is connected to the electrodes, for determining the scope of visual field according to the brain waves； the upper computer is connected to the virtual reality eye mask, for collecting a brain wave signal and a visual field scope signal. The method of the present invention greatly improves the efficiency of visual field examination, avoids the influence of a person's subjective response, and makes visual field screening become an intelligent detection instrument that can be used at home, without the needs of special operation and response from the detected person.
