Abstract
A wide-angle lens is applicable to a head-mounted display having a display screen. The wide-angle lens includes a first lens having a positive refractive power and a second lens having a positive refractive power. Light emitted by the display screen passes to a user through the second lens and the first lens sequentially. The wide-angle lens satisfies the following conditions: where fand fare the focal lengths of the first lens and the second lens, respectively, and f is the focal length of the wide-angle lens. The wide-angle lens has a greater view angle and achieves better parallax correction.
