Founded by Heidi Hertel to solve glasses for kids and parents, Fitz Frames makes made-to-measure eyewear using facial scans and 3D printing. Each pair is designed around the wearer’s measurements and manufactured at Fitz’s facility in Youngstown, Ohio, producing lightweight frames built one at a time in the USA. Customers use the Fitz app to try on styles virtually and order prescription, sunglass, or blue-light lenses.
