This would be an implanted mirrored sun- glasses window into the eyelid, so that you could close your eyes and still see through the eyelids, so you could protect your eyes from salt, wind etc, but still see through them, just with everything darkened. For sleep there would be opaque lenses.

Why not mirrored lenses for when your eyes are open? It's gonna suck the first time someone wearing these gets punched in the eye. Or they lose the opaque ones and have to try to sleep with their eyes "open".
