The company's developer partners range from logistics and manufacturing to patient care. These apps have long-been involved with the product formerly known as Google Glass through the business-focused "Glass at Work" programme.

Writing in his bog, Glass project leader Jay Kothari said that GE Aviation, AGCO, DHL, Dignity Health, NSF International, Sutter Health, Boeing and Volkswagen have been using Glass over the past several years, and make up just a sampling of 50 companies using the wearable.

Google Glass was found useful in factories and other enterprise environments. Google discovered this and began work on a product built by a team dedicated to building a new version of Glass for the enterprise.

The Glass Enterprise Edition glasses are lighter and more "comfortable for long term wear". They also offer more power and longer battery life and offer support for folks with prescription lenses, Wired said. The glasses, too, are stronger and do double duty as safety glasses.

This model, which has an upgraded 8-megapixel camera, has a red light that glows when the camera is recording.

The original glass launched in 2012, but it failed to catch on with consumers. Where it did succeed is with professionals, like field workers and doctors, who use the device to record information without needing to use their hands.

"Now the Glass product team is back at X, and we'll be collaborating with the Google Cloud team and our partners to help customers across a variety of business sectors make the most of Glass. Together, we're looking forward to seeing more businesses give their workers a way to work faster and in a more focused way, hands-free."
