Warby Parkers are cheaply designed: nose pads are not affixed with screws, and thus are prone to being lost. Most (all?) hinges are rigid, without spring suspension. It’s kind of ridiculous for these prices (compare with Zenni and Costco).
I have been very happy with my 1 year old pair of WP glasses. There aren't any nose pads or spring hinges but I haven't noticed any negative effects from those design choices. For $110 with anti-glare coating I have no complaints.
