Vuzix has updated its line of video eye-wear and is compatible with both 2D and 3D content, the glasses can display an equivalent of up to 75-inch screen as seen from a distance of 10 feet and feature separate focus adjustment for each eye as well as adjustable eye distance and viewing angles. The lenses also come in different colors for the fashion conscious.
Weighing approximately 3oz with twin 1280 x 720 LCD, 16 million color displays with 35 degree diagonal field of view and 16:9 / 4:3 aspect ratio. Brightness, contrast, hue and color saturation are adjustable via on-screen controls and eye separation is also adjustable. It even has an adjustable nose bridge for folks that have a nose like mine.
Connectivity options include composite AV cable, component video cable and AV cable for most videophones, portable DVDs, and camcorders, but there's no HDMI input or wireless connectivity. These can also connect to PCs and laptops for game playing with VR head tracking. Using them with a camera is cool for those high, low, or behind shots where you do not have to keep your eye in the viewfinder.
Two rechargeable AA batteries provide up to three hours of video playback and reportedly can be replaced with lithium ion batteries offering up to seven hours. The video-glasses are available now from $169 - $499. I love technology.

Moverio is an alternative $770 pair of glasses that sports a 80 inch 3D experience and has a slot for a picture card and plays music. Not quite HD quality, but close. LINK 2012 may be the year for a breakthrough.
