It's good to have a high quality pair from a local shop so you have something to compare Zenni or other online shops to. YMMV of course, but I've had good experiences with Zenni, and only had one pair out of dozens for my family that had issues (seemed to be uncentered or had the PD incorrect), and that was over 5 years ago. It's nice being able to grab a cheap pair of glasses for activities where there is a high probability of them getting damaged or lost, and having a backup pair handy. The reduced mental load of not having to worry is worth it!
