Please note: Device with FaceID required (iPhone XR and newer models, except the iPhone SE). Topology, the leading provider of augmented reality and optical measurements technology in the eyewear market, has re-imagined the way people shop for eyewear. Our 3-D Face Scan app unlocks the convenience and safety of online shopping with the professional guidance and precise optical measurements of the in-store experience. This is Topology's Touchless Optical Platform. Our groundbreaking process begins with an incredibly accurate 3D scan of your face, made possible by the amazing FaceID sensor embedded in compatible Apple devices. Our algorithms extract all your facial measurements, compare them against a growing database of branded eyewear products, and return the subset that are perfectly-tailored to you - viewable on the retailer's e-commerce website or on our retail iPad app and seamlessly integrated into the in-store shopping experience. Topology also uses your 3D scan to measure, with amazing precision, all necessary 3D optical measurements, enabling the delivery of even the most complicated and sophisticated of Rx lenses. For the first time, vision needs such as a strong Rx, high astigmatism, and/or progressive lenses are dispensed with unrivaled clarity.
