Virtual fitting systems and methods for spectacles

A computer-implemented method, comprising:

• receiving, from a user device at a fitting server, a selection of one or more spectacle frames from a plurality of spectacle frames in a frame database associated with the fitting server;
• obtaining, with the fitting server, facial landmark location information for a user of the user device based on sensor data from a sensor of the user device;
• obtaining, with the fitting server, frame landmark location information for each of the one or more spectacle frames;
• and
• generating, with a fitting engine of the fitting server, fit information for each of the one or more spectacle frames based on the facial landmark location information and the frame landmark location information;
• and
• providing the fit information for each of the one or more spectacle frames, with the fitting server for display at the user device.

A computer-implemented method, comprising:

• storing, in a frame database, one of a plurality of size categories for each of a plurality of spectacle frames, each size category corresponding to a range of user measurements;
• obtaining, using a sensor of an electronic device, three-dimensional location information for a user;
• determining, based on the three-dimensional location information, a user measurement for the user;
• identifying a corresponding one of the size categories for the user, based on the user measurement of the user and the ranges of user measurements for the size categories;
• and
• providing, for display, information associated with a subset of the plurality of spectacle frames, each of the spectacle frames in the subset having the identified corresponding one of the size categories.
