The Verge is reporting that Google will release four prescription frames designed to work with Google Glass. Google calls the frames the "Titanium collection," after the metal they're produced from. The four frame styles are designed by Google itself, rather than a traditional glasses designer, and have the necessary shape and hardware (i.e., a screw hole) for mounting Google Glass to the frames.
The Glass hardware itself is identical to the second revision of Glass, which features an optional ear bud and removable hardware for this exact purpose. The report says the Glass frames should be on sale sometime today for $225. That's $225 on top of the $1,499 Google charges for Glass, bringing the total cost to $1,724. After getting Glass and glasses frames, customers will still have to get prescription lenses cut for the frames, which will have to be done at an eyeglass shop.
Until now, it was extremely difficult for users of prescription glasses to even try Glass. Glass already comes mounted on a frame, so it was basically like trying to wear two pairs of glasses. Now that Glass can work with a much wider audience, Google says it will slowly ramp up the Explorer program and invite more users to purchase Glass. There is currently no purchase link for the frames, but the Google Glass Google+ page has links to the various frame styles of both glasses and sunglasses that will be available.
