1. A system for creating a model of a user-specific eyewear product, the system comprising: a data storage device storing instructions for creating the model of the user-specific eyewear product; and a processor configured to execute the instructions to perform a method comprising: obtaining an anatomic model of a user based on image data and/or measurement data of an anatomic feature of the user; receiving a configurable parametric model of a product for creating a user-specific version of the product, the configurable parametric model comprising one or more geometric parameters defining the geometry of at least a frame of the product; modifying one or more of the one or more geometric parameters of the configurable parametric model based on one or more geometric features derived from the anatomic model of the user to create an updated parametric model of the product; and generating an electronic file storing the updated parametric model of the product, for generating a display of the updated parametric model or for generating instructions for manufacturing the user-specific version of the product.
