Aside from the design, the major upgrade here is the addition of a second HD camera. Now, there's a sensor over each eye, which give the Specs some depth perception. There are also two buttons — one on each side of your face, that you can press to start recording a ten-second clip or hold down for a still image. As before, you don't have to do anything to stop recording. Just push down and the device captures 10 seconds of footage. And if you want to capture more, just keep hitting the button five more times to continue shooting up to a minute of video.

3D Snaps

The first benefit of the dual camera setup this is that the Specs can now take what the company calls 3D Snaps. It's a little hard to describe, but think of these like Portrait mode photos, but sort of in 3D. Your subject is rendered almost like a pop-up against a flat background. When you move your phone around, you'll see more of your subject's profile — like you're looking around a corner.

This works best when you can get some distance between your subject and the background, otherwise the effect is either completely unnoticeable or the back of your friend's head becomes a weird blob melted into what's behind them. Snap also recommends you get close to your subject for the best results — between three and fifteen feet away.

Depth for better AR filters

The other thing the added depth enables is smarter AR effects called 3D filters that you can add to your clips in Snapchat. On regular Stories, this is typically a flat overlay on your footage, like flowers falling all over your screen. With the Spectacles 3, the animated effects actually interact with your scene. So instead of flowers just falling straight down, they'll actually bounce off of tables, chairs and other surfaces. It's a little gimmicky, but they're fun to watch and play with.

I have to give Snap props for what it's been able to do with its depth-mapping. The Specs record stereoscopic 3D videos that I can launch in VR and watch in a headset. Real trees that I walked by on a Chelsea street had depth and dimension, even before I converted the clip to 3D. The falling flowers filter I mentioned before didn't just bounce off tables and chairs, but they also cascaded down the sides of buildings as if they were painted onto the bricks, then slouched onto the ground, gathering like leaves on a pond's surface.

I really enjoyed how aware these animations were of the environment. One of them displays faux red and silver heart-shaped balloons all over, and not only do they land on top of desks, but they also disappear behind pillars, showing up if you look behind the obstruction. This occlusion adds to the immersiveness of the filter and makes it feel more like physical objects interacting with the real world.

Currently, there are only 10 filters available, but Snap says it will continue to add new effects to keep things fresh for users, just like it does for regular shots from your phone.

The quality of the footage itself is good, too. The two HD cameras here captured clear, colorful videos, and a tree-lined street's fall foliage looked vibrant. In low light, however, the Spectacles 3 delivered noisy, somewhat blurry footage. Though, nobody should be wearing sunglasses indoors and at night.

Limits

That's one of the few limits of Spectacles 3 — since they're shades, you're meant to use them outdoors and in daylight. You can swap in prescription lenses, sure, but low light performance isn't great here, so don't get too excited about using them in a bar, at a fireworks show or at a concert.

You might also want to avoid taking them to the beach or by the pool. Unlike the Spectacles 2, which were IPx7 water-resistant, the new shades aren't rated at all. I definitely was worried when I got caught in the rain.They didn't seem to get damaged though, and should hold up under a light splash.

As impressed as I am by what the second camera adds to the experience, there are some other problems. For one, you'll still have to use the Snapchat app to download your media from the glasses, and apply the effects you want. You'll also have to save the clips to your phone before you can apply the 3D effects, which can take up a ton of space. Since these Snaps now contain twice the information they did before, they're a lot bigger and can take longer to transfer. Thankfully, they'll send over WiFi when available, instead of over Bluetooth.
