Prescription safety glasses will normally ship within 7-12 business days. Our production time can vary depending on frame availability and certain lens options. Your order will ship via the method you select during the checkout process. Unfortunately, the method of shipping that you choose will not cut down on production time. Therefore, selecting Next Day Air does not mean that you will receive your order the next day. It only means that UPS will ship it to you in one day from the time that they pick up the package from our facility.
