We did exactly this last time (prescription sunglasses and regular from Zenni). We went to Costco for the exam/prescription which was pretty hassle free. I'll set out the positives and negatives:

Positive: They nailed the prescription (perfect). The lenses were as thin as normal with the 1.67 "high-index polymer" upgrade (which is important as the prescription is bad in one eye, could result in super thick lenses). In all other respects they do what they say they do.

Negatives: We ran into an unexpected and ultimately fatal issue; even with perfect lenses and fine looking frames, my wife could not get them to sit straight or comfortably on her face. They'd slide down her nose and fall, both pairs. We bent them with pliers and a heat gun, followed the guide on Zenni's site, even had the gall to take them into an opticians (Standard Optical) and they tried adjusting them for us, no dice. This is on both pairs (sunglasses and regular). Even after our best attempts and taking them into a Standard Optical, we could not make it work.

We now have two pairs of Zenni sitting in a draw and had to spend another $180+ on just regular glasses from Costco (no sunglasses due to cost). These ones at least stay on her face. It is such an obnoxious and unusual issue to have, but two frames from two different lines of frames both didn't work for us and could not be fixed. It definitely shows the biggest problem with online glasses shopping in general, good prices, but if they don't fit your face then you're now out $170 (Plus whatever we spent at Costco after failing at Zenni).

This isn't meant to be a slam against Zenni in particular, they did what they said they'd do at a good price. This is a cautionary tale about online glasses shopping in general...



Zenni refunds 50% of the price for returns.

Eyebuydirect (14 days) and 39dollarglasses (30 days) offer full refund for returns.


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.
