Frame construction is generally much poorer quality. I've had them break from just taking them off my face too fast. Face fit is tricky, they allow you to select things like your "size" but this is broken down into "small/medium/large" when in reality it needs to take into account things like temple (arm) length, bridge width, etc. My main pair is perfect because I spent the big bucks on them and had a professional constantly tweaking them, putting them back on my face, tweaking them some more. And that comes with the ability to return to the store and have them do it again for free if I feel like I need to. Online you won't get any of that, so the fit isn't perfect. Optical clarity, no complaints. The lenses are good. But we're talking $500+ vs. $80.
