Abstract: The disclosure relates to a VR eyepiece system. The VR eyepiece system includes: a lens assembly, which includes a first lens, a second lens, a third lens and a fourth lens that are coaxially arranged in sequence from an eye side to an image side; a quarter-wave plate, which is attached to an image-side surface of a polarizing reflective film; a transflective film, which is attached to an image-side surface of the third lens; and a display assembly, which is arranged on an image-side surface of the fourth lens.
