Ray-Ban prescription glasses lost in Austin

My husband lost his Ray-Ban glasses a few weeks ago somewhere around Central Austin (or possibly elsewhere in Austin — he’s not exactly sure when he noticed they were missing). They’re prescription glasses, and this particular model is hard to replace. So he’s been struggling a bit — lots of squinting 🙈
We’d be really grateful if they turn up. A tasty treat of your choice is on us as a thank-you!
