Abstract: A conventional head-mounted display (HMDs) can display a virtual image at a fixed focus (e.g., infinite focus). If the user looks at an object that appears closer than the virtual image, then accommodation by the user's eyes will cause the virtual image to appear blurry. The HMDs disclosed herein include a dynamic electro-active focusing element that changes the focus of the virtual image to account for accommodation by the user. This dynamic electro-active focusing element may include a curved layer of electro-active material, such as nematic or bi-stable (e.g., cholesteric) liquid crystal, disposed between a static concave mirror and a convex surface on a beam splitter or other optical element. Changing the refractive index of the electro-active material causes the focus of the dynamic electro-active focusing element, making it possible to shift the virtual image's focus in as the user's eyes change focus.
