Google says it is joining forces with the frame giant behind Ray-Ban and other brands to create and sell Glass internet-linked eyewear in the US.
The California-based technology titan billed the partnership with Luxottica as its "biggest step yet into the emerging smart eyewear market".
Luxottica brands include Oakley, Alain Mikli, Ray-Ban and Vogue-Eyewear.
The announcement in a Google+ post came as the web titan sought to burnish the Glass image before its expected debut in the US this year.
Google last week debunked Glass myths, including that it invades privacy, distracts wearers and is for "technology-worshipping geeks".
"If someone wants to secretly record you, there are much, much better cameras out there than one you wear conspicuously on your face and that lights up every time you give a voice command, or press a button," Google said.
Google in February gave early adopters of its internet-connected eyewear a bit of advice: don't be "Glassholes".
It was the final suggestion in a recommended code of conduct posted online for software developers and others taking part in an Explorer program providing early access to Google Glass.
The internet titan appeared intent on avoiding the kinds of caustic run-ins that have seen some Glass wearers tossed from eateries, pubs or other establishments due to concerns over camera capabilities built into devices.
Don't be "creepy or rude (aka, a 'Glasshole')," Google said in a guide posted online for Explorer program members.
"Respect others and if they have questions about Glass don't get snappy."
Google suggest Glass wearers be polite and offer demonstrations to possibly win over the wary. Glass fans were advised it is proper to follow the same rules set down for smartphone use in businesses.
"If you're asked to turn your phone off, turn Glass off as well," Google said.
"Breaking the rules or being rude will not get businesses excited about Glass and will ruin it for other Explorers."
Google early this year unveiled a partnership with US vision insurer VSP to make prescription Glass and to reimburse some of the costs under health benefits.
That does not include the $1,500 price for Glass, which is in a test phase with a small number of "explorers".
Glass connects to the internet using Wi-Fi hot spots or, more typically, by being wirelessly tethered to mobile phones. Pictures or video are may be shared through the Google Plus social network.
During the testing phase, developers are creating apps for the eyewear, which can range from getting weather reports to sharing videos to playing games.
