If you've been waiting impatiently to get a pair of Google Glass, mark your calendar and grab your checkbook.
Google announced late Thursday that it will sell prototypes of the wearable computers for one day next week in an effort to expand its cadre of early testers, known as Explorers .
Google's wearable computer called Glass.
"Our Explorers are moms, bakers, surgeons, rockers, and each new Explorer has brought a new perspective that is making Glass better," wrote Google's Glass team in a post on its Google+ page. "But every day we get requests from those of you who haven't found a way into the program yet, and we want your feedback too. So in typical Explorer Program fashion, we're trying something new."
Glass will go on sale Tuesday at 9 a.m. ET. Any U.S. resident age 18 or over will have a chance to buy a pair of Glass for $1,500 plus tax.
The eyewear will be sold first come, first serve and the number of spaces in the Explorer program are limited. Google did not say how many people will be able to buy into the program.
To try for a chance to buy Glass, prospective buyers need to go to the Google Glass site, fill out a a brief form and and note why they're interested in the computerized eyeglasses.
"We're excited to meet our new Explorers, and we can't wait to hear your thoughts about Glass," the Glass team wrote.
Google began expanding its Explorer program in February 2013. Prospective users had to explain what they would do if they had a pair of Glass in 50 words or less. The company chose 8,000 potential users and developers to become Explorers. These early adopters started posting photos, videos and comments about all the different things they were doing with Glass.
For more than a year, the Explorers have worn Glass playing sports, treating patients in healthcare facilities, traveling and recording their children's birthday parties.
Google is expected to officially release Glass for sale sometime this year.
This week, Google announced that it is moving to push Glass use into the enterprise with its Glass at Work program.
More details about about the advancement of Glass and its app ecosystem is expected at Google I/O, the company's major developer conference, which will be held June 25 and 26 in San Francisco.
Registration for Google I/O is set to begin April 15.
