A see through display includes a variably transmissive element positioned between a real world view and an eye of a user, and a generated display optical system for generating a displayed information image superimposed over the real world view in the visual field of the user. The variably transmissive element is controllable to dynamically vary the light intensity passing through the element into the visual field of the user. The variably transmissive element may be spatially addressed to allow selective variable transfer of light intensity through the element into the visual field of the user.
