I ordered a pair of (non prescription) sunglasses from Warby Parker, which are very stylish, but one of the lenses dropped out within a week. I had them repaired, but the lens was so scratched from the fall that they were no longer wearable.
I ordered a pair of prescription glasses too, which were too wide at the temple to use. WP told me to have them repaired elsewhere and they would cover the cost. I was told by 3 opticians that the frames couldn't be repaired to fit. I contacted WP, but as I needed glasses right away ( and was holding the misshapen ones with an 80's style Croakie!) and they weren't amenable to doing anything for me much less a rush order, I went instead back to a real optical shop.
