Virtual reality device

A virtual reality device relates to the field of virtual reality simulation technology. The virtual reality device comprises a display screen (1), a housing (2), a Fresnel lens (3) and a pair of lenses (4). The Fresnel lens is arranged between a convex lens and the display screen. Light of the display screen penetrates through the Fresnel lens. In penetration of the light, the display screen is amplified; and a secondary amplification function is performed by means of the convex lens, thereby performing a dual-amplification function, making a picture fill a whole visual field. Because of small thickness of the Fresnel lens, the Fresnel lens can perfectly satisfy the requirement at a position where distance and weight are restricted. Through amplification of the Fresnel lens, a direct distance between the convex lens and a mobile phone is reduced. In other words, a deformation caused by the convex lens is greatly reduced, thereby greatly improving experience effect of virtual reality glasses. 种虚拟现实装置，涉及虚拟现实仿真技
