    Abstract: A VR equipment includes a casing, and an optical module, an eye movement module, and a display module located inside the casing. The optical module includes a lens barrel and first to fourth lenses located in the lens barrel and arranged in sequence from an object plane to an image plane along an optical axis. The eye movement module is located between the first and second lenses. The eye movement module has a light-emitting unit and a receiving unit. The light-emitting unit emits a detection light to human eyes which is then reflected. The reflected detection light is reflected at an object side surface of the second lens and then enters the receiving unit after passing through an object side surface and an image side surface of the first lens. The display module is at an image side surface of the fourth lens. The display module displays an image.
