Vision discomfort due to the accommodation‐convergence mismatch remains a challenge for current HMDs used for VR/AR applications. A potential solution of this issue is to use an adaptive focus lens that is lightweight, flat and has a large aperture. In this paper, we present a 5 cm diameter Liquid Crystal based focus tunable lens. Despite the large aperture, the lens has characteristics of fast switching speed(500ms), low driving voltage (<5 V), and low thickness (<5mm).
