Sony has unveiled eyeglasses that can show full-color video images. The prototype supports a QVGA resolution, weighs 120g, is 3mm thick at the lens, and has a contrast ratio of 50:1.

The glasses use a proprietary holographic waveguide and an optical engine made up of a LED light source and a transparent LCD panel. Video coming from the optical engine is reflected by a film in the holographic waveguide. It then bounces off a glass plate and is diffracted to the eyes by a second holographic film.
