Abstract

Systems and methods for creating fully custom products from scratch without exclusive use of off-the-shelf or pre-specified components. A system for creating custom products includes an image capture device for capturing image data and/or measurement data of a user. A computer is communicatively coupled with the image capture device and configured to construct an anatomic model of the user based on the captured image data and/or measurement data. The computer provides a configurable product model and enables preview and automatic or user-guided customization of the product model. A display is communicatively coupled with the computer and displays the custom product model superimposed on the anatomic model or image data of the user. The computer is further configured to provide the customized product model to a manufacturer for manufacturing eyewear for the user in accordance with the customized product model. The manufacturing system is configured to interpret the product model and prepare instructions and control equipment for the manufacturing of the customized product.
