A compact head-worn display with multiply folded optics providing displayed images overlaid onto a see-through view of a surrounding environment includes a solid prism of a first material with an angled planar surface to fold an optical axis and one or more surfaces that provide optical power, one or more additional lens elements with optical power made of a second material that is different from the material of the solid prism, an image source that provides image light associated with the displayed images, a combiner that folds the optical axis and directs the image light toward a user's eye and wherein the multiply folded optics provide a more compact head-worn display and the first and second materials are selected to reduce a lateral color in the displayed images.
