1. A computer system for obtaining one or more measurements used to construct vision-corrective lenses for an eyeglass frame, the computer system comprising: a server computing device comprising one or more physical processors programmed with computer program instructions to: obtain a user-provided image that includes an image of a user wearing the eyeglass frame; determine an identification of the eyeglass frame being worn by the user; obtain a predefined reference based on the identification, wherein the predefined reference includes an image of the eyeglass frame; compare the user-provided image with the predefined reference; resize the user-provided image and/or the predefined reference such that a size of the eyeglass frame from the user-provided image substantially matches a size of the eyeglass frame from the predefined reference based on the comparison; and determine one or more measurements used to construct the vision-corrective lenses based on the resized user-provided image and/or the predefined reference.
