A head mounted display includes a combiner configured to receive display light from a micro-display. The world-facing surface of the combiner has a curvature that corresponds to a user's vision correction prescription. The head mounted display also includes a corrective layer having a second curvature that corresponds to the user's vision correction prescription. The corrective layer is disposed on the eye-facing surface of the combiner such that the focal point of the display light is adjusted for the specific user as the display light exits the combiner towards the user's eye.
