You would use a special sort of display that would direct a distinct image to each eye.

3D displays that don't use special glasses already do this.

You made me google it; I had no idea those existed. At first sight, it looks like it should be able to do what you ask. Geez, it could even diagnose your (short|long)sightedness|astigmatism and recheck it every now and then.

Pretty sweet tech; I hope it gets commercially viable soon!
