The depth-sensing front camera on the iPhone X isn't just useful for unlocking your phone or making silly emoji clips. Eyewear maker Warby Parker has updated its Glasses app for iOS to include an iPhone X-only recommendation feature. Let the app scan your face and it'll recommend the frames that are most likely to fit your measurements. This isn't the same as modeling the frames on your face (wouldn't the iPhone X be ideal for that?), but it could save you a lot of hemming and hawing as you wonder which styles are a good match.
