glassed out
n. A vacant look and obliviousness to one's surroundings caused by reading and operating a Google Glass wearable computer.
And Glass hasn't been able to ditch what could be its true Achilles' heel: its dorky image. Labeled "Segway for your face," it has become the butt of jokes on late-night television and on the Internet. Not only have Glass wearers been subjected to public ridicule for looking "glassed out," they are referred to as a cross between Glass and a curse word.

But as The Atlantic Wire's Rebecca Greenfield has explained, even if it sounds right in theory, Glass wearers, in practice, just zone out. Silicon Valley technology workers at the epicenter of the Glass outbreak have reportedly given a new name to this state: "glassed out." As if lifted from the pages of a William Gibson novel, Google Glass becomes a pscyhotropic drug made of bits and metal rather than chemicals and gelatin.

The very best thing I learned this year at SXSW is that people in the Valley have coined a term for the weird, half-conscious expression that Google Glass wearers get on their faces when they are concentrating on doing things with the tiny little screen inside their glasses. They call it "glassed out," which you would use in a sentence like: "Barry." "Barry." "BARRY!!!" Oh, nvm, he's glassed out, that explains it, ok." I love it.

Glassed out is the modern update to Jonathan Franzen's "the schizophrenic eyes of the cellurlarly occupied" ( The Corrections ).
