The device sits at eyebrow level, higher than where eyeglasses would go.

From Tuesday, the Californian company is offering four styles of prescription frames and two new types of shades available to its "explorers" - the people trying out Glass.
The frames will cost $US225 ($A257.60) and the shades $US150. That's on top of the $US1500 price of Glass.
Users can take the frames to any optometrist for prescription lenses. Google says some insurance plans may cover the cost of the frames.
Glass's designers picked four basic but distinct frame styles. On one end is a chunky "bold" style that stands out. On the other is a "thin" design - to blend in as much as possible.
When Google unveiled Glass in a video nearly two years ago, it drew unfavourable comparisons to Bluetooth headsets, the trademarks of the fashion-ignorant technophile.
