I-Glasses makes a 3D head set with good resolution but it is rather clunky
looking. Probably not a good way to keep up with what is going on in the
real world.

Looking at a chartplotter and a 3d mapping program gave me some ideas.

Build a small computer display into the lenses of glasses. Wherever
you looked, they could either be transparent or display the positions
of buoys, etc and water depth contours superimposed on what you were
looking at.
