Google cofounder Sergey is smarting with a pair of black lens smart glasses on his face. He was trying out Google Glass. Eventually it flopped.

But it set the stage of wonderment and bewilderment about smart glasses.

Many tech companies have tried but none have truly popularized the idea of smart eyewear, but one succeeded. Facebook.

Called Ray-Ban Stories. Facebook hopes they'll be worn to take pictures and short videos, listen to music, and make phone calls, by anyone 13 or older.

Ray-Ban Stories worth $299. Built by Facebook and EsillorLuxottica.

The glasses come in three styles, including the iconic Ray-Ban Wayfarer, and five hues, including blue and green, are on the darker end of the spectrum. They're being sold at some Ray-Ban stores and at Ray-Ban.com, and are available to buyers in six countries, including the United States, Canada, and the United Kingdom.

Ray-Ban Stories solves one of the biggest issues facing Google Glass and many other chunky, funky smart glasses of the past. The electronics are so well hidden that there are just a few hints that something is different about these specs: there's a camera embedded in the edge of each side of the frame, for instance. But on a pair of shiny Wayfarers they seem to melt into the frame itself.
