This Phase I project will demonstrate the feasibility of using specially modified contact lenses combined with an LCD display illuminated with a wave-guided backlight to enable an 80 degree field of view see-through display. The new eyewear architecture being proposed is a radical departure from traditional near eye displays. Rather than present the eye with collimated rays of light that appear to originate from a distant source, the performance of the eye is enhanced by sophisticated contact lenses to enable short focal length accommodation of non-collimated light rays. The special contact lenses add one additional focal accommodation distance to the wearer s normal vision. This is done with no impact to the wearer s normal sight other than a slight attenuation of ambient brightness. The result is that the eye is able to observe the near-eye imagery over its full field of view while simultaneously observing the surrounding environment. This eliminates all of the imaging optics from the eyewear resulting in a see-thru display panel that can be bonded directly to standard ballistic eyewear. The proposed Phase 1 research will demonstrate the ability to view see-through monochromatic near eye imagery over an 80 degree field of view.
