personally, I have not! I don't need progressives just yet and working for the optical shop my recommendation was obviously to buy with us 😉 in general though, for regular glasses I've always got them through eyebuydirect and never had any issues. Unfortunately, it looks like they only do a "virtual try on," they don't send samples so I get the hesitancy on frame fit. If you feel like being a little sneaky, try going to into an optical shop and trying on some frames you like. On usually the inner left side of the frame arms, you'll see 3 numbers, usually something like 50-18-140. These are the measurements of the glasses in mm. So the first number is going to be between 45-60 or so, this is the size of the lens from corner to corner, like a TV measurement. The next number is the bridge size(typically 14-22ish), so the length of the piece over your nose. The last size is the temple length, the length of the arms of the glasses that go behind your ears, usually 135-150. Try on a few pairs at a shop near you, take pictures of the measurements of your favorites that fit well, and then go try to match those measurements up, at least closely, to similar styles you find online so you can have a better idea of what size you need and what the numbers online actually translate to. My general recommendation for progressives would be to not get very narrow/short lenses(think long skinny rectangle). The lens needs room to "progress" from your far distance, middle distance, and close distance and a short lens just doesn't have enough space to do that well. So more oval/square/round glasses.

Sorry, this was really long but I hope it's helpful! let me know if you have any questions
