Online support is good as well. First pair I ordered from them had a defective coating after the first 6 months (it was 'splotchy', it looked like water dried on the lenses but it wouldn't come off'). They sent me a replacement pair for free.

The only downside I have with online glasses is you making adjustments to the fitting of the glasses. Your eye doctor will usually do this for you when you buy glasses for them, but online glasses require you to do it yourself or go into a store (if they have one). With that said, still not a big enough negative for me to go back to buying from my eye doctor.

Warby will reimburse $50 to go to an eye doctor for fitting. See "Fit" here: https://www.warbyparker.com/help. I admittedly haven't needed to do this so I'm not sure what the experience is like.
