1. A computer-implemented method for creating a model of an individual-specific eyewear product, using a computer system, the method comprising:

  • receiving or modifying a first parametric model of an eyewear product, the first parametric model including a lens portion and a frame portion of the eyewear product;

    determining, for the first parametric model, a product geometric constraint between the lens portion and the frame portion of the eyewear product;

    obtaining an anatomic model of an individual'"'"'s anatomy;

    determining, using the anatomic model, a user measurement characterizing a distance or a relationship between the first parametric model and the anatomic model, the measurement defining one or more of;

    a vertex distance, pantoscopic tilt, monocular pupillary distance, ocular center height, or frame wrap calculated for the individual'"'"'s anatomy;

    determining an effect of the user measurement on the product geometric constraint;

    generating a second parametric model comprising a modification to both the lens portion and the frame portion of the first parametric model based on the determined effect; and

    generating a display of the second parametric model or generating an electronic file comprising instructions for manufacturing a physical embodiment of the eyewear product according to the second parametric model.
