Driven by Lumus' patented Light-guide Optical Element, a micro-display pod, and the Optical Engine which projects light into the lens -- where it is reflected back to the user's eye via reflectors embedded in the lens -- the Lumus' DK-32 delivers a bright 720p 3D-capable display that only weighs 27 grams.
While not everyone has been able to get their hands on Blu-ray movies yet, many are reporting a surprisingly poor visual display from former DVD reference star The Fifth Element.
Switching involves looking at an element of the screen and giving a big blink to select -- the display seems adjusted in such a way that normal blinks won't trigger it, so you're less likely to accidentally set something off.
