The invention discloses a wearable vision detection device based on electroencephalogram signals. The wearable vision detection device comprises portable electroencephalogram acquisition equipment, an electroencephalogram recognition module and a vision detection module, the portable electroencephalogram acquisition equipment is used for playing a stimulation normal form video and acquiring an electroencephalogram signal from the brain of a subject; the electroencephalogram recognition module is used for controlling video playing of the portable electroencephalogram acquisition equipment and verifying and analyzing electroencephalogram signals; the vision detection module is used for carrying out preprocessing, feature analysis and extraction, feature fusion and model detection on the electroencephalogram signals; wherein the fusion features of the subject are detected through a pre-constructed model, and the vision range of the subject is obtained. On the basis of an objective evaluation system based on visi
