Citing the popularity of smart wearables and the potential boom of augmented reality (AR)-based technology in the future, Facebook was said to be working with premium accessory brand Ray-Ban to develop its AR-based glasses. Later, the social media giant confirmed that it has partnered with Essilor Luxottica, the parent company of Ray-Ban, to launch an AR glass this year. Now, we have some more details about Facebook’s Ray-Ban AR glasses, coming straight from CEO Mark Zuckerberg.

Now, although the CEO did not reveal much about the upcoming wearable, we already know that it won’t come with an integrated display. The company has previously confirmed that it wants to develop smart glasses that are “flexible enough to work for most face shapes and sizes,” to cater to more people.
