Original Abstract Submitted
an xr display system includes a near-eye optical see-through xr display having an image presentation component with an eye-facing side and a world-facing side and configured to present virtual visual content to a user's eye from locations across an image presentation surface of the eye-facing side. a dynamic push lens positioned on the world-facing side and a dynamic pull lens positioned on the eye-facing side each include a liquid crystal cell dynamically switchable by an electrical stimulus between an inactive state and an active state. in the active state, the dynamic push lens converges environmental light approaching the image presentation component from the world-facing side by applying a positive optical power, and the dynamic pull lens diverges light passing out of the eye-facing side of the image presentation component toward the user's eye by applying a negative optical power.
