Vuzix has been a leader in video eyewear. Many of the headsets that Vuxix has been most known for look like typical virtual screen headsets.
At CES 2009 they introduced the Wrap 920AV which is eyewear that looks like standard sunglasses they are see through but can double as video eyewear. The Wrap 920AV allows you to play videos and at the same time allow you to see the world around you. The glasses kind of remind of heads up displays with significant more resolution.
The Wrap 920AV provides a 60-inch monitor as seen from 9 feet and has available expansion options all in a lightweight package that is less than 3 ounces.
