Abstract
Eyewear having a stereoscopic display including a lens system, and a push-pull lens set including prisms to produce a binocular overlap of two images that coincides with an accommodation plane. The overlap of two virtual images generated by a respective display as seen by the user's two eyes provides user comfort. The stereoscopic display may have a single accommodation plane, where the binocular overlap of the two virtual images depends on the location of the accommodation plane and the depth of the content formed by disparity in the two images. By providing the content at or near the location where the virtual images are at least substantially overlapped, the user viewing comfort is improved. The binocular overlap is controlled by tilting or steering the virtual images inward, such that the overlap occurs at the accommodation plane.
