A: We have a full-service, state-of-the-art lab right in the store. However, it depends on the type of lenses, the prescription and any additional specialty coatings required to make your glasses. If we are able to make the prescription lenses in our lab, it can take anywhere from an hour to a day. If we send the RX to an outside lab for any reason, it can take up to seven to ten days; however, we typically receive them back in our lab, sooner than that.
