Speculation that Google Glass will also come as prescription frames have been rife and now images of the wearable device have been spotted online, suggesting that the company has a prescription version in the works.

The images which show off a standard set of frames were shared by Google employee Brian Matiash before they were pulled, which suggests that they were not meant for public release.

The images were posted on the Google+ page of Matiash on Thursday, December 5, and showed the modified version of the Google Glass. Phandroid, however, managed to capture the photos before they were pulled down.

"Googler Brian Matiash is finally giving us a better view of prescription Google Glass, sharing a few images of the high-tech eyewear - likely still in its prototype stages - to his Google+ page. From the looks of it, frames carrying a design much like non-prescription Glass will need to be made specifically for Glass, with one side attaching to the main unit. This means if you were hoping to bring your current favorite pair of eyeglasses with you, they likely wont have a proper Glass fitment," reports Phandroid.

While the prescription variant of Google Glass resembles the current version, it does not have the steel band which enables the wearer to put their regular glasses in what appears to be a cradle in the device's body. At this juncture, however, it is not known whether the cradle will be able to house traditional glasses.

A possibility exists, that the prescription version of Google Glass could have a permanently fixed eyeglass component, which would need a specific adjustment for each device.

Earlier this month, Google started issuing Explorers invitations that would allow them to swap their original $15,00 Google Glass for an updated version. Explorers could also change the color free of charge.
