Google will makes it controversial Internet-linked Glass eyewear available for purchase for a limited time in the United States beginning on April 15.

Anyone in the United States with $1,500 to spend on Glass will be able to join the ranks of “explorers” who have gotten to test out the devices prior to them hitting the market, the California-based Internet titan said Thursday in a post at Google+ social network.

“Our Explorers are moms, artists, surgeons, rockers, and each new Explorer has brought a new perspective that is making Glass better,” Google said in the post.

“But every day we get requests from those of you who haven’t found a way into the program yet, and we want your feedback too.”

On April 15, Google will commence what it billed as the biggest expansion of the Explorer program to date by letting anyone in the US buy the eyewear online.

Google said online sales would take place “for a limited time,” but did not specify how long that might be.
