As noted by several posts on the Google+ Glass community page (via SearchEngineLand), Google has begun sending emails to Google Glass owners allowing them to invite a friend to the Explorer program. Google has been distributing Glass on an invite only basis up until now (on top of its #IfIhadglass contests), but this marks the first time it is allowing users to invite others into the beta program. You might remember Google used the same invite-a-friend strategy when Gmail first launched.

It appears the invites are only being sent to a select number of Glass owners, as Google’s Sarah Price later confirmed that “no more emails are going out right now for this experiment.”

Those being invited will have to be in the US and 18 years or older, and also have to pick up their Glass in either New York, Los Angeles, or San Francisco. We’d assume those invited will be paying the same $1500 price tag that other Explorers have paid, but Google didn’t provide any info on pricing.
