Eyepiece with expanded field angle

[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings.

[0033] see figure 1 , an eyepiece for expanding the field of view, comprising an eyepiece main body, the front end surface of the eyepiece main body is a first curved surface 1, the rear end surface of the eyepiece main body is a second curved surface 2, and both the first curved surface 1 and the second curved surface 2 are rotationally symmetrical surfaces ; The center of the first curved surface 1 is convex, the edge of the first curved surface 1 is concave, and the second curved surface 2 is convex. The eyepiece structure adopted in the present invention is used for virtual reality device display, and the traditional double convex eyepiece structure is optimized. Under the premise of 2K resolution, within a specific space range, the distorti
