Another question if I might! Are glasses/specticals of non magic nature fir correcting vision a thing in Faerûn? Oh, yes. Many are pince-nez or monocle format, or hang down from a headband above them; some jewelers and artificers wear magnifying lenses in this manner, too.#Realmslore

Then the next question would be how expensive they are… It depends. On how complex and powerful the lenses, and where and when you're buying them (large city with competition, like a temple of Gond = cheaper than if you must buy from a traveling merchant). Waterdeep: reading glasses as low as 5gp, but usually 25-100 gp.#Realmslore
