Field-of-view (FoV) is one of the key parameters of head-mounted displays (HMDs), because a wider FoV gives higher presence and immersion in a virtual environment. We propose a method that expands the FoV of HMDs by using two kinds of lenses with different levels of magnification. A central convex lens is surrounded by a Fresnel lens with high magnification that fills the peripheral vision with a blurred image. This method doesn't need complicated optics, and is advantageous in terms of device cost and weight because only two additional Fresnel lenses are necessary.
