Isabelle Olsson, lead designer of Google's Project Glass, talks about the design of the Google Glass during the keynote at Google's annual developer conference, in San Francisco on June 27, 2012. - 

We know Google plans to make its high tech spectacles called Google Glass available this year. The price tag: about $1,500 a pair. But are these lens-less frames really a technological revolution?

"It's cool for a piece of technology," says Joshua Topolsky, editor and chief of The Verge, who took an official test run of the specs around New York City. But "it has to transcend a piece of technology because you are wearing it on your face."

Though Topolsky says the average person may not be quick to don Google Glass -- at least in its current state -- partnerships with companies like Rayban or Warby Parker could help win over mainstream users.

And then there are slick new features which could interest more than just tech geeks. Glass makes use of Google's Knowledge Graph which serves up instant, easy-to-read information when you search.

"If you ask for the weather, it won't just give you links to the weather, it will show you what the weather is on a nice stylized card," explains Topolsky.
