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.

A variable focus flashlight module including a first lens, a second lens, a third lens, and a light source module sequentially from a magnified side to a minified side along an optical axis of the variable focus flashlight module is provided. The first lens has a negative refracting power. The second lens has a positive refracting power. The third lens has a positive refracting power. The light source module includes multiple light emitting elements arranged in an array. A total length of the variable focus flashlight module is a constant value, and a ratio of a focal length of the second lens to a focal length of the third lens falls within a range of 1.78 to 3.02.
