Google Glass, Google’s new information spectacles, have generated quite a bit of controversy since the quirky devices were first revealed.

Now, it seems that privacy concerns over Google Glass have ruffled the feathers of some lawmakers in Congress.

The New York Times reports that eight members of Congress have sent a letter to Google CEO Larry Page that contains eight questions about Google Glass. The purpose of the letter is to determine whether the search engine giant’s new technology will respect personal privacy. A response is expected by June 14.

The newspaper says that the letter asked Page how Google plans on gathering and storing data from Google Glass and how the company plans to protect the privacy of people in the vicinity of those utilizing the new technology. The eight lawmakers also asked Google whether the device would have facial recognition technology.

Google’s new tech glasses will allow people to connect to the Internet, snap photos, and record and view videos. Google Glass users will also be able to text with friends and interact with various social media sites.

Though the aim of Google Glass is to make access to information more convenient, the wearable technology has raised some privacy concerns. Due to these privacy concerns, Google Glass has already been banned in several places. For example, Las Vegas-based Sapphire Gentlemen’s Club said they will be requiring that customers leave their Google Glass at the door, reports NBC News.
