Noe & Pedro Ruiz at Adafruit have created a pair of open source near-eye video glasses combined with a Raspberry Pi. Their 3D Printed design turns a pair of 'private display glasses' into a "google glass"-like form factor. It easily clips to your prescription glasses, and can display any kind of device with Composite Video like a Raspberry Pi. They have a , a tutorial on how to build them, along with the 3d files required to print it out."
