That depends on the order - it ranges anywhere from 1 week to 6 weeks. The specific production time for your loupes is shown on the product page when you are placing your order.
Traditional TTL and Flip-up Loupes: 1-2 weeks
ErgoPrism Loupes: 4-6 weeks
Actually, there really isn't any measuring involved - all we need is 2 images from you wearing one of our ErgoFit Frames and we can do the rest. To learn more about the process, check out this Youtube video.
Of course! Our LumaShield is designed to work with all Loupes. Additionally, because of their design, our ErgoPrism Loupes fit under some face shields where other Loupes cannot.
