Google has put the Glass Explorer Edition up for sale, following the recent release of the Glass Development Kit.
The hardware, which has been made available for purchase by developers via a code in an email, follows the release of the GDK, which allows developers to further control aspects of the smart eyewear.
The Explorer Edition of the Glass uses a high resolution display placed just above the right eye to give the impression of viewing a 25-inch high definition screen eight feet away.
The Glass also includes a five-megapixel camera with 720P video recording, Bluetooth, Wi-Fi and 12GB of storage for apps and media.
A consumer version of the Glass is predicted for released next year.
