We work closely with a lab that is able to produce our prescription lenses between 48 hours to 2 weeks depending on the prescription and special options that may have added to the lenses. Once we receive the lenses from the lab we inspect them and assemble the safety glasses ordered. Our process from the time we receive your prescription to when you receive your glasses will take 1-4 weeks. If you have a time restraint call or email us to see how we may assist you.
