Abstract
A wearable display system, such as a Head Mounted Display, having a display engine producing light, preferably linearly polarized light, which defines a synthetic image that is relayed to a wire grid polarizing combiner which overlays the synthetic image onto a real image of an object of the outside world, and wherein the real image is contemporaneously viewed through the wire grid polarizing combiner by the wearer of the system. The wire grid polarizing combiner can be curved in at least one axis, and preferably two axis such that optical power is added to the wire grid polarizing combiner.
