By all accounts, they are working on some sort of device that projects a light field onto the retina. But that is strictly additive. You can't darken anything. This image you see of the elephant in your hand - no way to do that. At best it'd be rather transparent.
Unless there is some aspect of vision that somebody here would like to chime in on [locality on the retinal sensor allowing to perceive darkness by lightening up other areas?], color me deeply skeptical. It seems like "fullscreen" Google Glass, at best.
