Abstract: 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.
