之前 Google Glass 推出了 Eplorers 计划，让用家购买使用 Google Glass；跟着在一个月前推出了一日限定购买 Google Glass。现在 Google Glass 再进一步开放，给美国用家购买。
在 Google+ 上公布，虽然 Google Glass 仍在 Beta 阶段，但就会进一步开放，由今天起只要 Google 有货的，美国用家就可以购买 Google Glass。
Last week we told you we’d be trying out new ways to find Explorers. Well, we weren’t kidding. We learned a lot when we opened our site a few weeks ago, so we’ve decided to move to a more open beta. We’re still in the Explorer Program while we continue to improve our hardware and software, but starting today anyone in the US can buy the Glass Explorer Edition, as long as we have it on hand: google.com/glass
