In a blogpost on Tuesday, the Internet company said the eyewear will be available at USD 1,500 as long as the stocks lasted.

Google opened sales for the gadget to public in US for USD 1,500 last month for a day to make it available to more than just the select group of users such as apps developers.

 Google, which is still working to improve hardware and software of the product, did not say how many glasses it would sell or whether it will make more of these glasses after they run out of stock.

The consumer version is expected to go on sale to the general public towards the end of 2014.

A stamp-sized electronic screen mounted on the side of a pair of eyeglass frames, Google Glass can record video, access email, provide turn-by-turn driving directions and retrieve information from the web by connecting wirelessly to a user's cell phone.

Google Glass has also raised privacy concerns, prompting some legislators to propose bans on the gadget.
