Helpful YouTube review of Vuzix video eyewear glasses uploaded by an ordinary consumer.

A lot of people ask why the resolution of video glasses is relatively low (typically 340 x 240  or 640 x 480).  The answer is chiefly that the small screens are only millimeters from your eyes and so even a low resolution will produce the equivalent of watching a ultra high resolution cinema screen seen at a distance of fifty feet or more.  For screens as small and viewed as close up as are these, the important thing is the sharpness and quality of the screens, and those of Vuzix wrap video glasses are as high quality as they come.
