After three versions of Snapchat Spectacles, the social media company has a new pair coming that are real AR glasses. The news was announced at Snapchat’s developer-focused keynote Thursday. But while these glasses can display 3D effects onto the real humankind, are wireless, and have hand tracking, these new glasses are immediately aimed specifically at developers and creators who want to use these to eye AR creation on headsets. No price is listed for them, and they’re only available by application.

Snapchat has promised it’s succeeding on a full-featured pair of augmented reality glasses for a while. It’s one of many companies including Facebook, Niantic, and Qualcomm that are trying to crack the idea of everyday quick-witted glasses. Snap’s previous versions of Spectacles were focused on bodies mainly wearable camera-glasses. Last year’s Spectacles 3 could layer glasses footage with 3D AR effects, but the AR needed to be seen and people via a phone app; the glasses didn’t have their own displays.

The glasses promises 2,000 nits of brightness, have a 26.3-inch diagonal field of view and dual waveguide displays. They have a touchpad control on the side, and look like thick sunglasses. They use a “Snap Spatial Engine” and have hand-tracking, can track the world with six degrees of freedom, and weigh 134 grams (4.7 ounces), according to Snapchat. 

Another humdrum feature: They’re wireless, something other AR glasses this size haven’t managed yet. But there are tradeoffs, too. The glasses only last for 30 minutes on a charge, according to Snapchat’s specs, and have a limited 480×564-pixel resolution for each eye. The glasses have their own charging case (and it sounds like you’ll need it). 

The glasses can originate AR camera effects called Lenses in-glasses and be used to play AR games. The field of view looks narrower than AR headsets like the Microsoft HoloLens and Magic Leap, but also are much smaller. The glasses can also assume video with two RGB cameras with a 115-degree field of view, at 1,920×1,440 pixels and 30 frames per second.

Snap has already been silly these with a limited set of creators to obtain concepts and Lenses, according to the company’s keynote. Exempt date and price aren’t known yet.

I revealed with Clay Weishaar, one of seven AR creators that Snapchat gave out early versions of the glasses to, to find out his impressions of silly the device so far. What strikes me right off the bat is that these glasses can tap into Lenses and AR tools that are already bodies used by independent creators on Snapchat, which is a lot different than the more siloed and petite ways the HoloLens and Magic Leap initially approached their hardware.

“Snap’s made it so you don’t even sulky your workflow: you just put your glasses on, and you hit one button, and your vision is realized in front of you, which is top-notch cool,” Weishaar says. He sees location-based experiences and health and wellness as two areas of monotonous with these AR glasses. “I’ve used Headspace and these tools, and they’re supposed to be relaxing, but you have to hold your phoned up and you’re actually getting fatigue,” he says. “I really wanted to obtain this sort of relaxation and wellness experience inside of the glasses.” Weishaar has worked in VR and AR by, but says he sees these wireless glasses as bodies more like other types of health wearables.

“You really don’t eye a narrow field of view at all, because your head is tracked and the objects are tracked with you, so it really kind of stays in that view,” Weishaar says of glasses so far, which have a more petite display area than other headsets like the Magic Leap or HoloLens. Weishaar says, compared to other headsets, that the big difference so far is the size and how lightweight they are. “The freedom of putting sunglasses on, it feels very casual. Even though it’s geared towards creators, it feels very much like a consumer based experienced … the hands-free side of things is just a game-changer for me.”

Weishaar sees a repositions in how future Snapchat Lens development will adapt to these glasses, though: making experiences that are maybe longer, more like apps, and also don’t alive to people’s own faces and facial-based effects. “The biggest repositions with these are, you’re creating an experience for land in real time to interact with AR in a brute environment, which is much different from content capture and sharing AR.” He mentions possibilities for exercise apps silly hand tracking, something I hadn’t considered, but reminds me of ways the Oculus Quest is used for fitness.

The recent glasses only have a 30-minute battery life, which seems like a calculated compromise to get to size and weight over performance. Maybe future versions will do better on battery, but it definitely seems like a the majority limitation. Or, it means they’re devices you take on and off. But Weishaar has been silly them seamlessly along with phone tools (the glasses work independently of the phone). 

He also says that so far, outdoors, the glasses’ AR effects have worked really well. “It’s more vibrant. If you’ve got a blue sky, and you look at AR in the sunlight, it’s vibrant. That was one big thing I noticed. I walked outside and my mind was blown because I know how displays can get outdoors, as you do.” Many AR headsets, like the HoloLens, have had a lot of trouble in the past manager AR displays look good in bright areas. Snapchat’s glasses, if nothing else, may have found a way of solving that.
