We didn't return because we didn't feel it was Zenni's fault. There was no defect with the glasses, they just didn't happen to fit my wife's face and couldn't be adjusted to.

I was just posting to point out an inherent flaw with the entire concept of online glasses ordering and one I have no solution to.

I'd love to imagine a future where they can 3D scan a face and produce bespoke frames.

The unconditional return warranty exists because fit & style are difficult online. Returns are included in the price you paid, it’s like insurance, not everyone needs it, but sometimes you do.

Warby Parker is using the iPhone X camera for facial scan & frame recommendations.

how good a recommendation can be is based on resolution http://eyednamarket.com/multivendor/images/5.jpg

Thanks. What’s the best USB-connected camera that can be purchased today for high resolution facial 3D scanning on a PC?

Artec Eva but is very expensive.
