A display system includes a display configured to emit an image for viewing by a viewer. The display system further includes one or more phase lens layers disposed on, and substantially co-extensive in length and width with the display. Each of the one or more phase lens layers is configured to have different first and second focal lengths for different respective first and second polarization states. The display system further includes a first polarization modifying layer disposed between the display and the one or more phase lens layers. The first polarization modifying layer is configured to receive the emitted image and transmit a transmitted image. The transmitted image has the first and second polarization states in response to different respective first and second signals applied to the first polarization modifying layer.
