Google said Thursday it was offering a free upgrade to the new Google Glass Explorer Edition for early buyers.
The upgrade is said to be faster and more durable, with an added slot to install on ordinary glasses.
But Google said the renewed version would not be compatible with first-generation accessories. The offer is valid through Feb. 5 and is open to those who bought Google Glass before Oct. 28.
The high-tech wearable device works as a miniature computer, featuring a side-mounted touchpad and a transparent display in one of the lenses.
